Parameter settings in 2 set-ups can be saved. Change
between the 2 parameter set-ups and edit 1 set-up, while
another set-up is active.
Slip compensation
The frequency converter compensates for the motor slip by
giving the frequency a supplement that follows the
measured motor load keeping the motor speed almost
constant.
Smart logic control (SLC)
The SLC is a sequence of user-dened actions executed
when the associated user-dened events are evaluated as
true by the SLC.
Thermistor
A temperature-dependent resistor placed where the
temperature is to be monitored (frequency converter or
motor).
Trip
A state entered in fault situations, for example, if the
frequency converter is subject to an overtemperature or
when the frequency converter is protecting the motor,
process, or mechanism. Restart is prevented until the cause
of the fault does not exist and the trip state is canceled by
activating reset or, sometimes, by being programmed to
reset automatically. Do not use trip for personal safety.
Trip lock
A state entered in fault situations when the frequency
converter is protecting itself and requiring physical
intervention, for example, if the frequency converter is
subject to a short circuit on the output. A locked trip can
only be canceled by cutting o mains, removing the cause
of the fault, and reconnecting the frequency converter.
Restart is prevented until the trip state is canceled by
activating reset or, sometimes, by being programmed to
reset automatically. Do not use trip lock for personal safety.
VT characteristics
Variable torque characteristics used for pumps and fans.
VVC
+
If compared with standard voltage/frequency ratio control,
voltage vector control (VVC
+
) improves the dynamics and
the stability, both when the speed reference is changed
and in relation to the load torque.
1.7
Power Factor
The power factor indicates to which extent the frequency
converter imposes a load on the mains supply. The power
factor is the ratio between I
1
and I
RMS
, where I
1
is the
fundamental current, and I
RMS
is the total RMS current
including harmonic currents. The lower the power factor,
the higher the I
RMS
for the same kW performance.

3 Product Overview
3.1 Advantages
3.1.1 Why use a Frequency Converter for
Controlling Fans and Pumps?
A frequency converter takes advantage of the fact that
centrifugal fans and pumps follow the laws of propor-
tionality for such fans and pumps. For further information,
see chapter 3.1.3 Example of Energy Savings.
3.1.2 The Clear Advantage - Energy Savings
The clear advantage of using a frequency converter for
controlling the speed of fans or pumps lies in the
electricity savings.
When comparing with alternative control systems and
technologies, a frequency converter is the optimum energy
control system for controlling fan and pump systems.

Illustration 3.2 Energy Savings with Frequency Converter
Solution
When using a frequency converter to reduce fan capacity
to 60% - more than 50% energy savings may be obtained
in typical applications.
3.1.3 Example of Energy Savings
As shown in Illustration 3.3, the ow is controlled by
changing the RPM. By reducing the speed by only 20%
from the rated speed, the ow is also reduced by 20%.
This is because the ow is directly proportional to the
RPM. The consumption of electricity, however, is reduced
by 50%.
If the system in question only needs to be able to supply a
ow that corresponds to 100% a few days in a year, while
the average is below 80% of the rated ow for the
remainder of the year, the amount of energy saved is even
more than 50%.

3.1.4 Comparison of Energy Savings
The Danfoss frequency converter solution oers major
savings compared with traditional energy saving solutions
such as discharge damper solution and inlet guide vanes
(IGV) solution. This is because the frequency converter is
able to control fan speed according to thermal load on the
system, and the frequency converter has a built-in facility
that enables the frequency converter to function as a
building management system, BMS.
Illustration 3.3 shows typical energy savings obtainable
with 3 well-known solutions when fan volume is reduced
to 60%.
As the graph shows, more than 50% energy savings can be
achieved in typical applications.

This example is calculated based on pump characteristics
obtained from a pump datasheet.
The result obtained shows energy savings of more than
50% at the given ow distribution over a year. The

3.1.6 Better Control
If a frequency converter is used for controlling the ow or
pressure of a system, improved control is obtained.
A frequency converter can vary the speed of the fan or
pump, obtaining variable control of ow and pressure.
Furthermore, a frequency converter can quickly adapt the
speed of the fan or pump to new ow or pressure
conditions in the system.
Simple control of process (ow, level, or pressure) utilizing
the built-in PI control.

3.1.7 Star/Delta Starter or Soft Starter not
Required
When larger motors are started, it is necessary in many
countries to use equipment that limits the start-up current.
In more traditional systems, a star/delta starter or soft
starter is widely used. Such motor starters are not required
if a frequency converter is used.
As illustrated in Illustration 3.8, a frequency converter does
not consume more than rated current.

The following sections give typical examples of
applications within HVAC.
3.1.12 Variable Air Volume
VAV or variable air volume systems, control both the
ventilation and temperature to fulll the requirements of a
building. Central VAV systems are considered to be the
most energy-ecient method to air condition buildings. By
designing central systems instead of distributed systems, a
greater eciency can be obtained.
The eciency comes from utilizing larger fans and larger
chillers which have much higher eciencies than small
motors and distributed air-cooled chillers. Savings are also
seen from the decreased maintenance requirements.

3.1.13 The VLT Solution
While dampers and IGVs work to maintain a constant
pressure in the ductwork, a frequency converter solution
saves much more energy and reduces the complexity of
the installation. Instead of creating an articial pressure
drop or causing a decrease in fan eciency, the frequency
converter decreases the speed of the fan to provide the
ow and pressure required by the system.
Centrifugal devices such as fans behave according to the
centrifugal laws. This means that the fans decrease the
pressure and ow they produce as their speed is reduced.
Their power consumption is thereby signicantly reduced.

3.1.14 Constant Air Volume
CAV, or constant air volume systems, are central ventilation
systems usually used to supply large common zones with
the minimum amounts of fresh tempered air. They
preceded VAV systems and are therefore found in older
multi-zoned commercial buildings as well. These systems
preheat amounts of fresh air utilizing air handling units
(AHUs) with a heating coil, and many are also used to air
condition buildings and have a cooling coil. Fan coil units
are frequently used to assist in the heating and cooling
requirements in the individual zones.
3.1.15 The VLT Solution
With a frequency converter, signicant energy savings can
be obtained while maintaining decent control of the
building. Temperature sensors or CO
2
sensors can be used
as feedback signals to frequency converters. Whether
controlling temperature, air quality, or both, a CAV system
can be controlled to operate based on actual building
conditions. As the number of people in the controlled area
decreases, the need for fresh air decreases. The CO
2
sensor
detects lower levels and decreases the supply fans speed.
The return fan modulates to maintain a static pressure
setpoint or
xed dierence between the supply and return
airows.
With temperature control, especially used in air
conditioning systems, as the outside temperature varies as
well as the number of people in the controlled zone
changes, dierent cooling requirements exist. As the
temperature decreases below the setpoint, the supply fan
can decrease its speed. The return fan modulates to
maintain a static pressure setpoint. By decreasing the air
ow, energy used to heat or cool the fresh air is also
reduced, adding further savings.
Several features of the Danfoss HVAC dedicated frequency
converter can be utilized to improve the performance of
the CAV system. One concern of controlling a ventilation
system is poor air quality. The programmable minimum
frequency can be set to maintain a minimum amount of
supply air regardless of the feedback or reference signal.
The frequency converter also includes a PI controller, which
allows monitoring both temperature and air quality. Even if
the temperature requirement is fullled, the frequency
converter maintains enough supply air to satisfy the air
quality sensor. The controller is capable of monitoring and
comparing 2 feedback signals to control the return fan by
maintaining a xed dierential airow between the supply
and return ducts as well.

3.1.16 Cooling Tower Fan
Cooling tower fans cool condenser-water in water-cooled
chiller systems. Water-cooled chillers provide the most
ecient means of creating chilled water. They are as much
as 20% more ecient than air cooled chillers. Depending
on climate, cooling towers are often the most energy
ecient method of cooling the condenser-water from
chillers.
They cool the condenser water by evaporation.
The condenser water is sprayed into the cooling tower
until the cooling towers ll to increase its surface area. The
tower fan blows air through the ll and sprayed water to
aid in the evaporation. Evaporation removes energy from
the water dropping its temperature. The cooled water
collects in the cooling towers basin where it is pumped
back into the chillers condenser and the cycle is repeated.
3.1.17 The VLT Solution
With a frequency converter, the cooling tower fans can be
controlled to the required speed to maintain the
condenser-water temperature. The frequency converters
can also be used to turn the fan on and o as needed.
Several features of the Danfoss HVAC dedicated frequency
converter can be utilized to improve the performance of
cooling tower fans applications. As the cooling tower fans
drop below a certain speed, the eect the fan has on
cooling the water becomes small. Also, when utilizing a
gearbox to frequency control the tower fan, a minimum
speed of 40–50% is required.
The customer programmable minimum frequency setting is
available to maintain this minimum frequency even as the
feedback or speed reference calls for lower speeds.
Also as a standard feature, the frequency converter can be
programmed to enter a sleep mode and stop the fan until
a higher speed is required. Additionally, some cooling
tower fans have undesirable frequencies that may cause
vibrations. These frequencies can easily be avoided by
programming the bypass frequency ranges in the
frequency converter.

3.1.18 Condenser Pumps
Condenser water pumps are primarily used to circulate
water through the condenser section of water cooled
chillers and their associated cooling tower. The condenser
water absorbs the heat from the chiller's condenser section
and releases it into the atmosphere in the cooling tower.
These systems are used to provide the most ecient
means of creating chilled water, they are as much as 20%
more ecient than air cooled chillers.
3.1.19 The VLT Solution
Frequency converters can be added to condenser water
pumps instead of balancing the pumps with a throttling
valve or trimming the pump impeller.
Using a frequency converter instead of a throttling valve
simply saves the energy that would have been absorbed
by the valve. This can amount to savings of 15–20% or
more. Trimming the pump impeller is irreversible, thus if
the conditions change and higher ow is required the
impeller must be replaced.

3.1.20 Primary Pumps
Primary pumps in a primary/secondary pumping system
can be used to maintain a constant ow through devices
that encounter operation or control diculties when
exposed to variable ow. The primary/secondary pumping
technique decouples the primary production loop from the
secondary distribution loop. This allows devices such as
chillers to obtain constant design ow and operate
properly while allowing the rest of the system to vary in
ow.
As the evaporator ow rate decreases in a chiller, the
chilled water begins to become overchilled. As this
happens, the chiller attempts to decrease its cooling
capacity. If the ow rate drops far enough, or too quickly,
the chiller cannot shed its load suciently and the chillers
safety trips the chiller requiring a manual reset. This
situation is common in large installations especially when 2
or more chillers in parallel are installed if primary/
secondary pumping is not utilized.
3.1.21 The VLT Solution
Depending on the size of the system and the size of the
primary loop, the energy consumption of the primary loop
can become substantial.
A frequency converter can be added to the primary system
to replace the throttling valve and/or trimming of the
impellers, leading to reduced operating expenses. 2 control
methods are common:
Flow meter
Because the desired
ow rate is known and is constant, a
ow meter installed at the discharge of each chiller, can be
used to control the pump directly. Using the built-in PI
controller, the frequency converter always maintains the
appropriate ow rate, even compensating for the changing
resistance in the primary piping loop as chillers and their
pumps are staged on and o.
Local speed determination
The operator simply decreases the output frequency until
the design ow rate is achieved.
Using a frequency converter to decrease the pump speed
is very similar to trimming the pump impeller, except it
does not require any labor, and the pump eciency
remains higher. The balancing contractor simply decreases
the speed of the pump until the proper ow rate is
achieved and leaves the speed xed. The pump operates
at this speed any time the chiller is staged on. Because the
primary loop does not have control valves or other devices
that can cause the system curve to change, and the
variance due to staging pumps and chillers on and o is
usually small, this xed speed remains appropriate. If the
ow rate needs to be increased later in the systems life,
the frequency converter can simply increase the pump
speed instead of requiring a new pump impeller.

3.1.22 Secondary Pumps
Secondary pumps in a primary/secondary chilled water
pumping system distribute the chilled water to the loads
from the primary production loop. The primary/secondary
pumping system is used to hydronically de-couple 1 piping
loop from another. In this case, the primary pump is used
to maintain a constant ow through the chillers while
allowing the secondary pumps to vary in ow, increase
control and save energy.
If the primary/secondary concept is not used in the design
of a variable volume system when the ow rate drops far
enough or too quickly, the chiller cannot shed its load
properly. The chillers low evaporator temperature safety
then trips the chiller requiring a manual reset. This
situation is common in large installations especially when 2
or more chillers in parallel are installed.
3.1.23 The VLT Solution
While the primary-secondary system with 2-way valves
improves energy savings and eases system control
problems, the true energy savings and control potential is
realized by adding frequency converters.
With the proper sensor location, the addition of frequency
converters allows the pumps to vary their speed to follow
the system curve instead of the pump curve.
This results in the elimination of wasted energy and
eliminates most of the overpressurization that 2-way valves
can be subjected to.
As the monitored loads are reached, the 2-way valves close
down. This increases the dierential pressure measured
across the load and the 2-way valve. As this dierential
pressure starts to rise, the pump is slowed to maintain the
control head also called setpoint value. This setpoint value
is calculated by summing the pressure drop of the load

In the conguration shown in Illustration 3.17,
parameter 1-00 Conguration Mode is set to [0] Open loop.
The resulting reference from the reference handling system
or the local reference is received and fed through the ramp
limitation and speed limitation before being sent to the
motor control. The output from the motor control is then
limited by the maximum frequency limit.
3.2.2 PM/EC+ Motor Control
The Danfoss EC+ concept provides the possibility for using
high-ecient PM motors (permanent magnet motors) in
IEC standard enclosure sizes operated by Danfoss
frequency converters.
The commissioning procedure is comparable to the
existing one for asynchronous (induction) motors by
utilizing the Danfoss VVC
+
PM control strategy.
Customer advantages:
Free choice of motor technology (permanent
magnet or induction motor).
Installation and operation as know on induction
motors.
Manufacturer independent when selecting system
components (for example, motors).
Best system eciency by selecting best
components.
Possible retrot of existing installations.
Power range: 45 kW (60 hp) (200 V), 0.37–90 kW
(0.5–121 hp) (400 V), 90 kW (121 hp) (600 V) for
induction motors and 0.37–22 kW (0.5–30 hp)
(400 V) for PM motors.
Current limitations for PM motors:
Currently only supported up to 22 kW (30 hp).
LC lters are not supported with PM motors.
Kinetic back-up algorithm is not supported with
PM motors.
Support only complete AMA of the stator
resistance Rs in the system.
No stall detection (supported from software
version 2.80).
3.2.3 Local (Hand On) and Remote (Auto
On) Control
The frequency converter can be operated manually via the
local control panel (LCP) or remotely via analog/digital
inputs or serial bus. If allowed in parameter 0-40 [Hand on]
Key on LCP, parameter 0-44 [O/Reset] Key on LCP, and
parameter 0-42 [Auto on] Key on LCP, it is possible to start
and stop the frequency converter via LCP by pressing
[Hand On] and [O/Reset]. Alarms can be reset via the
[O/Reset] key.

Local reference forces the conguration mode to open-
loop, independent on the setting of
parameter 1-00 Conguration Mode.
Local reference is restored at power-down.
3.2.4 Control Structure Closed Loop
The internal controller allows the frequency converter to
become a part of the controlled system. The frequency
converter receives a feedback signal from a sensor in the
system. It then compares this feedback to a setpoint
reference value and determines the error, if any, between
these 2 signals. It then adjusts the speed of the motor to
correct this error.
For example, consider a pump application where the speed
of a pump is to be controlled to ensure a constant static
pressure in a pipe. The static pressure value is supplied to
the frequency converter as the setpoint reference. A static
pressure sensor measures the actual static pressure in the
pipe and supplies this data to the frequency converter as a
feedback signal. If the feedback signal is greater than the
setpoint reference, the frequency converter slows the
pump down to reduce the pressure. In a similar way, if the
pipe pressure is lower than the setpoint reference, the
frequency converter automatically speeds the pump up to
increase the pressure provided by the pump.

Illustration 3.19 Control Structure Closed-loop
While the default values for the closed-loop controller of
the frequency converter often provide satisfactory
performance, the control of the system can often be
optimized by adjusting parameters.
3.2.5 Feedback Conversion
In some applications, it may be useful to convert the
feedback signal. One example of this is using a pressure
signal to provide ow feedback. Since the square root of
pressure is proportional to ow, the square root of the
pressure signal yields a value proportional to the ow. See
Illustration 3.20.

3.2.6 Reference Handling
Details for open-loop and closed-loop operation.
Illustration 3.21 Block Diagram Showing Remote Reference
The remote reference consists of:
Preset references.
External references (analog inputs and serial
communication bus references).
The preset relative reference.
Feedback-controlled setpoint.
Up to 8 preset references can be programmed in the
frequency converter. The active preset reference can be
selected using digital inputs or the serial communications
bus. The reference can also be supplied externally, most
commonly from an analog input. This external source is
selected by 1 of the 3 reference source parameters
(parameter 3-15 Reference 1 Source,
parameter 3-16 Reference 2 Source, and
parameter 3-17 Reference 3 Source). All reference resources
and the bus reference are added to produce the total
external reference. The external reference, the preset
reference, or the sum of the 2 can be selected to be the
active reference. Finally, this reference can by be scaled
using parameter 3-14 Preset Relative Reference.
The scaled reference is calculated as follows:
Reference = X + X ×
Y
100
Where X is the external reference, the preset reference or
the sum of these and Y is parameter 3-14 Preset Relative
Reference in [%].
If Y, parameter 3-14 Preset Relative Reference, is set to 0%,
the reference is not aected by the scaling.

3.2.7 Tuning the Drive Closed-loop
Controller
Once the frequency converter's closed-loop controller has
been set up, test the performance of the controller. Often,
its performance may be acceptable using the default
values of parameter 20-93 PI Proportional Gain and
parameter 20-94 PI Integral Time. However, sometimes it
may be helpful to optimize these parameter values to
provide faster system response while still controlling speed
overshoot.
3.2.8 Manual PI Adjustment
1. Start the motor.
2. Set parameter 20-93 PI Proportional Gain to 0.3
and increase it until the feedback signal begins to
oscillate. If necessary, start and stop the
frequency converter or make step changes in the
setpoint reference to attempt to cause oscillation.
3. Reduce the PI proportional gain until the
feedback signal stabilizes.
4. Reduce the proportional gain by 40–60%.
5. Set parameter 20-94 PI Integral Time to 20 s and
reduce it until the feedback signal begins to
oscillate. If necessary, start and stop the
frequency converter or make step changes in the
setpoint reference to attempt to cause oscillation.
6. Increase the PI integral time until the feedback
signal stabilizes.
7. Increase the integral time by 15–50%.
3.3
Ambient Running Conditions
The frequency converter has been designed to meet the
IEC/EN 60068-2-3 standard, EN 50178 9.4.2.2 at 50 °C
(122 °F).
The ambient temperature measured over 24 hours should
be at least 5 °C (41 °F) lower than the maximum ambient
temperature. If the frequency converter is operated at high
ambient temperature, decrease the continuous output
current.

CAUTION
INSTALLATION ENVIRONMENTS
Do not install the frequency converter in environments
with airborne liquids, particles, or gases that may aect
or damage the electronic components. Failure to take
necessary protective measures increases the risk of
stoppages, potentially causing equipment damage and
personnel injury.
Liquids can be carried through the air and condense in the
frequency converter and may cause corrosion of
components and metal parts. Steam, oil, and salt water
may cause corrosion of components and metal parts. In
such environments, use equipment with enclosure rating
IP54. As an extra protection, coated printed circuit boards
can be ordered as an option (standard on some power
sizes).
Airborne particles such as dust may cause mechanical,
electrical, or thermal failure in the frequency converter. A
typical indicator of excessive levels of airborne particles is
dust particles around the frequency converter fan. In dusty
environments, use equipment with enclosure rating IP54 or
a cabinet for IP20/TYPE 1 equipment.
In environments with high temperatures and humidity,
corrosive gases such as sulphur, nitrogen, and chlorine
compounds cause chemical processes on the frequency
converter components.
Such chemical reactions rapidly
aect and damage the
electronic components. In such environments, mount the
equipment in a cabinet with fresh air ventilation, keeping
aggressive gases away from the frequency converter.
An extra protection in such areas is a coating of the
printed circuit boards, which can be ordered as an option.
Before installing the frequency converter, check the
ambient air for liquids, particles, and gases. This is done by
observing existing installations in this environment. Typical
indicators of harmful airborne liquids are water or oil on
metal parts, or corrosion of metal parts.
Excessive dust particle levels are often found on instal-
lation cabinets and existing electrical installations. One
indicator of aggressive airborne gases is blackening of
copper rails and cable ends on existing installations.

General Aspects of EMC
3.4.1 Overview of EMC Emissions
Frequency converters (and other electrical devices)
generate electronic or magnetic
elds that may interfere
with their environment. The electromagnetic compatibility
(EMC) of these eects depends on the power and the
harmonic characteristics of the devices.
Uncontrolled interaction between electrical devices in a
system can degrade compatibility and impair reliable
operation. Interference may take the form of mains
harmonics distortion, electrostatic discharges, rapid voltage
uctuations, or high-frequency interference. Electrical
devices generate interference along with being aected by
interference from other generated sources.
Electrical interference usually arises at frequencies in the
range 150 kHz to 30 MHz. Airborne interference from the
frequency converter system in the range 30 MHz to 1 GHz
is generated from the inverter, the motor cable, and the
motor.
Capacitive currents in the motor cable coupled with a high
dU/dt from the motor voltage generate leakage currents,
as shown in Illustration 3.52.
The use of a shielded motor cable increases the leakage
current (see Illustration 3.52) because shielded cables have
higher capacitance to ground than unshielded cables. If
the leakage current is not ltered, it causes greater
interference on the mains in the radio frequency range
below approximately 5 MHz. Since the leakage current (I
1
)
is carried back to the unit through the shield (I
3
), there is
only a small electro-magnetic eld (I
4
) from the shielded
motor cable according to Illustration 3.52.
The shield reduces the radiated interference, but increases
the low-frequency interference on the mains. Connect the
motor cable shield to the frequency converter enclosure as
well as on the motor enclosure. This is best done by using
integrated shield clamps to avoid twisted shield ends
(pigtails). Pigtails increase the shield impedance at higher
frequencies, which reduces the shield
eect and increases
the leakage current (I
4
).
If a shielded cable is used for relay, control cable, signal
interface, and brake, mount the shield on the enclosure at
both ends. In some situations, however, it is necessary to
break the shield to avoid current loops.
If the shield is to be placed on a mounting plate for the
frequency converter, the mounting plate must be made of
metal, to convey the shield currents back to the unit.
Moreover, ensure good electrical contact from the
mounting plate through the mounting screws to the
frequency converter chassis.

When using unshielded cables, some emission
requirements are not complied with, although most
immunity requirements are observed.
To reduce the interference level from the entire system
(unit+installation), make motor and brake cables as short
as possible. Avoid placing cables with a sensitive signal
level alongside motor and brake cables. Radio interference
higher than 50 MHz (airborne) is especially generated by
the control electronics.

3.4.4 Overview of Harmonics Emission
A frequency converter takes up a non-sinusoidal current
from mains, which increases the input current I
RMS
. A non-
sinusoidal current is transformed with a Fourier analysis
and split into sine-wave currents with dierent frequencies,
that is, dierent harmonic currents I
n
with 50 Hz basic
frequency:
I
1
I
5
I
7
Hz 50 250 350
Table 3.8 Harmonic Currents
The harmonics do not aect the power consumption
directly, but increase the heat losses in the installation
(transformer, cables). So, in plants with a high percentage
of rectier load, maintain harmonic currents at a low level
to avoid overload of the transformer and high temperature
in the cables.
175HA034.10
Illustration 3.53 DC-link Coils
NOTICE
Some of the harmonic currents might disturb communi-
cation equipment connected to the same transformer or
cause resonance with power factor correction batteries.
To ensure low harmonic currents, the frequency converter
is equipped with DC-link coils as standard. This normally
reduces the input current I
RMS
by 40%.
The voltage distortion on the mains supply voltage
depends on the size of the harmonic currents multiplied
by the mains impedance for the frequency in question. The
total voltage distortion THDv is calculated based on the
individual voltage harmonics using this formula:

It is the responsibility of the installer or user of the
equipment to ensure, by consultation with the distribution
network operator if necessary, that the equipment is
connected only to a supply with a short-circuit power S
sc
greater than or equal to specied above.
Other power sizes can be connected to the public supply
network by consultation with the distribution network
operator.
Compliance with various system level guidelines:
The harmonic current data in Table 3.10 to Table 3.17 are
given in accordance with IEC/EN 61000-3-12 with reference
to the Power Drive Systems product standard. They may be
used as the basis for calculation of the harmonic currents'
inuence on the power supply system and for the
documentation of compliance with relevant regional
guidelines: IEEE 519 -1992; G5/4.
3.4.7 Immunity Requirements
The immunity requirements for frequency converters
depend on the environment where they are installed. The
requirements for the industrial environment are higher
than the requirements for the home and
oce
environment. All Danfoss frequency converters comply
with the requirements for the industrial environment and
therefore comply also with the lower requirements for
home and oce environment with a large safety margin.
3.5
Galvanic Isolation (PELV)
PELV oers protection through extra low voltage.
Protection against electric shock is ensured when the
electrical supply is of the PELV type and the installation is
made as described in local/national regulations on PELV
supplies.
All control terminals and relay terminals 01-03/04-06
comply with PELV (protective extra low voltage) (does not
apply to grounded delta leg above 440 V).
Galvanic (ensured) isolation is obtained by
fullling
requirements for higher isolation and by providing the
relevant creepage/clearance distances. These requirements
are described in the EN 61800-5-1 standard.
The components that make up the electrical isolation, as
described, also comply with the requirements for higher
isolation and the relevant test as described in EN
61800-5-1.
The PELV galvanic isolation can be shown in
Illustration 3.55.
To maintain PELV, all connections made to the control
terminals must be PELV, for example, thermistors must be
reinforced/double insulated.

WARNING
DISCHARGE TIME
Touching the electrical parts could be fatal - even after
the equipment has been disconnected from mains.
Also make sure that other voltage inputs have been
disconnected, such as load sharing (linkage of DC-link),
and the motor connection for kinetic back-up.
Before touching any electrical parts, wait at least the
amount of time indicated in Table 2.1.
Shorter time is allowed only if indicated on the
nameplate for the specic unit.
WARNING
LEAKAGE CURRENT HAZARD
Leakage currents exceed 3.5 mA. Failure to ground the
frequency converter properly can result in death or
serious injury.
Ensure the correct grounding of the equipment
by a certied electrical installer.
WARNING
RESIDUAL CURRENT DEVICE PROTECTION
This product can cause a DC current in the protective
conductor. Where a residual current device (RCD) is used
for protection in case of direct or indirect contact, only
an RCD of Type B is allowed on the supply side of this
product. Otherwise, apply another protective measure,
such as separation from the environment by double or
reinforced insulation, or isolation from the supply system
by a transformer. See also application note Protection
against Electrical Hazards.
Protective grounding of the frequency converter and the
use of RCDs must always follow national and local
regulations.
3.7 Extreme Running Conditions
Short circuit (motor phase-phase)
Current measurement in each of the 3 motor phases or in
the DC-link, protects the frequency converter against short
circuits. A short circuit between 2 output phases causes an
overcurrent in the inverter. The inverter is turned o
individually when the short circuit current exceeds the
allowed value (alarm 16, Trip Lock).
For information about protecting the frequency converter
against a short circuit at the load sharing and brake
outputs, see chapter 8.3.1 Fuses and Circuit Breakers.
Switching on the output
Switching on the output between the motor and the
frequency converter is allowed. The frequency converter is
not damaged in any way by switching on the output.
However, fault messages may appear.
Motor-generated overvoltage
The voltage in the DC link is increased when the motor
acts as a generator. This occurs in following cases:
The load drives the motor (at constant output
frequency from the frequency converter), that is
the load generates energy.
During deceleration (ramp-down) if the inertia
moment is high, the friction is low, and the ramp-
down time is too short for the energy to be
dissipated as a loss in the frequency converter,
the motor, and the installation.
Incorrect slip compensation setting
(parameter 1-62 Slip Compensation) may cause
higher DC-link voltage.
The control unit may attempt to correct the ramp if
parameter 2-17 Over-voltage Control is enabled.
The frequency converter turns o to protect the transistors
and the DC-link capacitors when a certain voltage level is
reached.
Mains drop-out
During a mains dropout, the frequency converter keeps
running until the DC-link voltage drops below the
minimum stop level, which is typically 15% below the
frequency converter's lowest rated supply voltage. The
mains voltage before the drop-out and the motor load
determines how long it takes for the frequency converter
to coast.
3.7.1 Motor Thermal Protection (ETR)
Danfoss uses ETR to protect the motor from being
overheated. It is an electronic feature that simulates a
bimetal relay based on internal measurements. The charac-
teristic is shown in Illustration 3.56.

The X-axis shows the ratio between I
motor
and I
motor
nominal. The Y-axis shows the time in seconds before the
ETR cuts o and trips the frequency converter. The curves
show the characteristic nominal speed at twice the
nominal speed and at 0.2x the nominal speed.
It is clear that at lower speed the ETR cuts o at lower
heat due to less cooling of the motor. In that way, the
motor is protected from being overheated even at low
speed. The ETR feature calculates the motor temperature
based on actual current and speed.
3.7.2 Thermistor Inputs
The thermistor cutout value is >3 k.
Integrate a thermistor (PTC sensor) in the motor for
winding protection.
Motor protection can be implemented using a range of
techniques:
PTC sensor in motor windings.
Mechanical thermal switch (Klixon type).
Electronic thermal relay (ETR).

5.1.1 Mains and Motor Connection
The frequency converter is designed to operate all
standard 3-phase asynchronous motors. For maximum
cross-section on cables, see chapter 8.4 General Technical
Data.
Use a shielded/armored motor cable to comply
with EMC emission
specications and connect
this cable to both the decoupling plate and the
motor.
Keep the motor cable as short as possible to
reduce the noise level and leakage currents.
For further details on mounting the decoupling
plate, see FC 101 Decoupling Plate Mounting
Instruction.
Also see EMC-Correct Installation in
chapter 5.1.2 EMC-compliant Electrical Installation.
For details on how to connect the frequency
converter to mains and motor, see chapter

5.1.2 EMC-compliant Electrical Installation
Pay attention to the following recommendations to ensure
EMC-correct electrical installation.
Use only shielded/armored motor cables and
shielded/armored control cables.
Connect the shield to ground at both ends.
Avoid installation with twisted shield ends
(pigtails), because this may aect the shielding
eect at high frequencies. Use the cable clamps
provided instead.
It is important to ensure good electrical contact
from the installation plate through the installation
screws to the metal cabinet of the frequency
converter.
Use starwashers and galvanically conductive
installation plates.
Do not use unshielded/unarmored motor cables
in the installation cabinets.

7 RS485 Installation and Set-up
7.1 RS485
7.1.1 Overview
RS485 is a 2-wire bus interface compatible with multi-drop
network topology, that is, nodes can be connected as a
bus, or via drop cables from a common trunk line. A total
of 32 nodes can be connected to 1 network segment.
Repeaters divide network segments.
NOTICE
Each repeater functions as a node within the segment in
which it is installed. Each node connected within a given
network must have a unique node address across all
segments.
Terminate each segment at both ends, using either the
termination switch (S801) of the frequency converters or a
biased termination resistor network. Always use shielded
twisted pair (STP) cable for bus cabling, and follow good
common installation practice.
Low-impedance ground connection of the shield at every
node is important. Connect a large surface of the shield to
ground, for example with a cable clamp or a conductive
cable gland. Apply potential-equalizing cables to maintain
the same ground potential throughout the network -
particularly in installations with long cables.
To prevent impedance mismatch, always use the same
type of cable throughout the entire network. When
connecting a motor to the frequency converter, always use
shielded motor cable.

Table 7.2 Modbus Communication Parameter Settings
7.1.5 EMC Precautions
NOTICE
Observe relevant national and local regulations
regarding protective ground connection. Failure to
ground the cables properly can result in communication
degradation and equipment damage. To avoid coupling
of high frequency noise between the cables, keep the
RS485 communication cable away from motor and brake
resistor cables. Normally, a distance of 200 mm (8 in) is
sucient. Maintain the greatest possible distance
between the cables, especially where cables run in
parallel over long distances. When crossing is
unavoidable, the RS485 cable must cross motor and
brake resistor cables at an angle of 90°.

7.2 FC Protocol
7.2.1 Overview
The FC protocol, also referred to as FC bus or standard bus,
is the Danfoss standard
eldbus. It denes an access
technique according to the master-slave principle for
communications via a serial bus.
One master and a maximum of 126 slaves can be
connected to the bus. The master selects the individual
slaves via an address character in the telegram. A slave
itself can never transmit without rst being requested to
do so, and direct message transfer between the individual
slaves is not possible. Communications occur in the half-
duplex mode.
The master function cannot be transferred to another node
(single-master system).
The physical layer is RS485, thus utilizing the RS485 port
built into the frequency converter. The FC protocol
supports
dierent telegram formats:
A short format of 8 bytes for process data.
A long format of 16 bytes that also includes a
parameter channel.
A format used for texts.
7.2.2 FC with Modbus RTU
The FC protocol provides access to the control word and
bus reference of the frequency converter.
The control word allows the Modbus master to control
several important functions of the frequency converter:
Start.
Stop of the frequency converter in various ways:
- Coast stop.
- Quick stop.
- DC brake stop.
- Normal (ramp) stop.
Reset after a fault trip.
Run at various preset speeds.
Run in reverse.
Change of the active set-up.
Control of the 2 relays built into the frequency
converter.
The bus reference is commonly used for speed control. It is
also possible to access the parameters, read their values,
and where possible, write values to them. Accessing the
parameters oers a range of control options, including
controlling the setpoint of the frequency converter when
its internal PI controller is used.
7.3
Parameter Settings to Enable the
Protocol
To enable the FC protocol for the frequency converter, set
the following parameters.

7.4 FC Protocol Message Framing Structure
7.4.1 Content of a Character (Byte)
Each character transferred begins with a start bit. Then 8
data bits are transferred, corresponding to a byte. Each
character is secured via a parity bit. This bit is set at 1
when it reaches parity. Parity is when there is an equal
number of 1s in the 8 data bits and the parity bit in total.
A stop bit completes a character, thus consisting of 11 bits
in all.

A byte denoting the telegram length (LGE).
A byte denoting the frequency converter address
(ADR).
Several data bytes (variable, depending on the type of
telegram) follow.

7.4.3 Telegram Length (LGE)
The telegram length is the number of data bytes plus the
address byte ADR and the data control byte BCC.

Address format 1–126
Bit 7 = 1 (address format 1–126 active).
Bit 0–6 = frequency converter address 1–126.
Bit 0–6 = 0 broadcast.
The slave returns the address byte unchanged to the
master in the response telegram.
7.4.5 Data Control Byte (BCC)
The checksum is calculated as an XOR-function. Before the
rst byte in the telegram is received, the calculated
checksum is 0.
7.4.6 The Data Field
The structure of data blocks depends on the type of
telegram. There are 3 telegram types, and the type applies
for both control telegrams (masterslave) and response
telegrams (slavemaster).
The 3 types of telegram are:
Process block (PCD)
The PCD is made up of a data block of 4 bytes (2 words)
and contains:
Control word and reference value (from master to
slave).
Status word and present output frequency (from
slave to master).

7.4.9 Index (IND)
The index is used with the parameter number to read/
write access parameters with an index, for example,
parameter 15-30 Alarm Log: Error Code. The index consists
of 2 bytes: a low byte and a high byte.
Only the low byte is used as an index.
7.4.10 Parameter Value (PWE)
The parameter value block consists of 2 words (4 bytes),
and the value depends on the dened command (AK). The
master prompts for a parameter value when the PWE block
contains no value. To change a parameter value (write),
write the new value in the PWE block and send from the
master to the slave.
When a slave responds to a parameter request (read
command), the present parameter value in the PWE block
is transferred and returned to the master. If a parameter
contains several data options, for example

the value in the PWE block. Serial communication is only
capable of reading parameters containing data type 9 (text
string).
Parameter 15-40 FC Type to parameter 15-53 Power Card
Serial Number contain data type 9.
For example, read the unit size and mains voltage range in
parameter 15-40 FC Type. When a text string is transferred
(read), the length of the telegram is variable, and the texts
are of dierent lengths. The telegram length is dened in
the 2
nd
byte of the telegram (LGE). When using text
transfer, the index character indicates whether it is a read
or a write command.
To read a text via the PWE block, set the parameter
command (AK) to F hex. The index character high-byte
must be 4.

The programming guide contains the descriptions of
attributes of each parameter. Parameter values are
transferred as whole numbers only. Conversion factors are
used to transfer decimals.
Parameter 4-12 Motor Speed Low Limit [Hz] has a conversion
factor of 0.1. To preset the minimum frequency to 10 Hz,
transfer the value 100. A conversion factor of 0.1 means
that the value transferred is multiplied by 0.1. The value
100 is thus perceived as 10.0.

Modbus RTU Overview
7.6.1 Introduction
Danfoss assumes that the installed controller supports the
interfaces in this document, and strictly observes all
requirements and limitations stipulated in the controller
and frequency converter.
The built-in Modbus RTU (remote terminal unit) is
designed to communicate with any controller that
supports the interfaces dened in this document. It is
assumed that the user has full knowledge of the
capabilities and limitations of the controller.
7.6.2 Overview
Regardless of the type of physical communication
networks, this section describes the process that a
controller uses to request access to another device. This
process includes how the Modbus RTU responds to
requests from another device, and how errors are detected
and reported. It also establishes a common format for the
layout and contents of telegram elds.
During communications over a Modbus RTU network, the
protocol:
Determines how each controller learns its device
address.
Recognizes a telegram addressed to it.
Determines which actions to take.
Extracts any data or other information contained
in the telegram.
If a reply is required, the controller constructs the reply
telegram and sends it.
Controllers communicate using a master/slave technique in
which only the master can initiate transactions (called
queries). Slaves respond by supplying the requested data
to the master, or by acting as requested in the query.
The master can address individual slaves, or initiate a
broadcast telegram to all slaves. Slaves return a response
to queries that are addressed to them individually. No
responses are returned to broadcast queries from the
master.
The Modbus RTU protocol establishes the format for the
master query by providing the following information:
The device (or broadcast) address.
A function code dening the requested action.
Any data to be sent.
An error-checking eld.
The response telegram of the slave device is also
constructed using Modbus protocol. It contains elds
conrming the action taken, any data to be returned, and
RS485 Installation and Set-...

77
an error-checking eld. If an error occurs in receipt of the
telegram, or if the slave is unable to perform the requested
action, the slave constructs and sends an error message.
Alternatively, a timeout occurs.
7.6.3 Frequency Converter with Modbus
RTU
The frequency converter communicates in Modbus RTU
format over the built-in RS485 interface. Modbus RTU
provides access to the control word and bus reference of
the frequency converter.
The control word allows the Modbus master to control
several important functions of the frequency converter:
Start.
Various stops:
- Coast stop.
- Quick stop.
- DC brake stop.
- Normal (ramp) stop.
Reset after a fault trip.
Run at various preset speeds.
Run in reverse.
Change the active set-up.
Control built-in relay of the frequency converter.
The bus reference is commonly used for speed control. It is
also possible to access the parameters, read their values,
and, where possible, write values to them. Accessing the
parameters
oers a range of control options, including
controlling the setpoint of the frequency converter when
its internal PI controller is used.

Table 7.13 Byte Details
7.8.2 Modbus RTU Telegram Structure
The transmitting device places a Modbus RTU telegram
into a frame with a known beginning and ending point.
This allows receiving devices to begin at the start of the
telegram, read the address portion, determine which
device is addressed (or all devices, if the telegram is
broadcast), and to recognize when the telegram is
completed. Partial telegrams are detected and errors set as
a result. Characters for transmission must be in
hexadecimal 00–FF format in each eld. The frequency
converter continuously monitors the network bus, also
during silent intervals. When the rst eld (the address
eld) is received, each frequency converter or device
decodes it to determine which device is being addressed.
Modbus RTU telegrams addressed to 0 are broadcast
telegrams. No response is permitted for broadcast
telegrams. A typical telegram frame is shown in Table 7.14.

7.8.3 Start/Stop Field
Telegrams start with a silent period of at least 3.5 character
intervals. The silent period is implemented as a multiple of
character intervals at the selected network baud rate
(shown as Start T1-T2-T3-T4). The rst eld to be
transmitted is the device address. Following the last
transmitted character, a similar period of at least 3.5
character intervals marks the end of the telegram. A new
telegram can begin after this period.
Transmit the entire telegram frame as a continuous stream.
If a silent period of more than 1.5 character intervals
occurs before completion of the frame, the receiving
device
ushes the incomplete telegram and assumes that
the next byte is the address eld of a new telegram.
Similarly, if a new telegram begins before 3.5 character
intervals after a previous telegram, the receiving device
considers it a continuation of the previous telegram. This
behavior causes a timeout (no response from the slave),
since the value in the nal CRC eld is not valid for the
combined telegrams.
7.8.4 Address Field
The address eld of a telegram frame contains 8 bits. Valid
slave device addresses are in the range of 0–247 decimal.
The individual slave devices are assigned addresses in the
range of 1–247. 0 is reserved for broadcast mode, which all
slaves recognize. A master addresses a slave by placing the
slave address in the address eld of the telegram. When
the slave sends its response, it places its own address in
this address eld to let the master know which slave is
responding.
7.8.5 Function Field
The function eld of a telegram frame contains 8 bits. Valid
codes are in the range of 1–FF. Function elds are used to
send telegrams between master and slave. When a
telegram is sent from a master to a slave device, the
function code eld tells the slave what kind of action to
perform. When the slave responds to the master, it uses
the function code eld to indicate either a normal (error-
free) response, or that some kind of error occurred (called
an exception response).
For a normal response, the slave simply echoes the original
function code. For an exception response, the slave returns
a code that is equivalent to the original function code with
its most
signicant bit set to logic 1. In addition, the slave
places a unique code into the data eld of the response
telegram. This code tells the master what kind of error
occurred, or the reason for the exception. Also refer to
chapter 7.8.11 Function Codes Supported by Modbus RTU and
chapter 7.8.12 Modbus Exception Codes.
7.8.6 Data Field
The data eld is constructed using sets of 2 hexadecimal
digits, in the range of 00–FF hexadecimal. These digits are
made up of 1 RTU character. The data eld of telegrams
sent from a master to a slave device contains additional
information which the slave must use to perform
accordingly.
The information can include items such as:
Coil or register addresses.
The quantity of items to be handled.
The count of actual data bytes in the
eld.
7.8.7 CRC Check Field
Telegrams include an error-checking eld, operating based
on a cyclic redundancy check (CRC) method. The CRC eld
checks the contents of the entire telegram. It is applied
regardless of any parity check method used for the
individual characters of the telegram. The transmitting
device calculates the CRC value and appends the CRC as
the last eld in the telegram. The receiving device
recalculates a CRC during receipt of the telegram and
compares the calculated value to the actual value received
in the CRC eld. 2 unequal values result in bus timeout.
The error-checking eld contains a 16-bit binary value
implemented as 2 8-bit bytes. After the implementation,
the low-order byte of the eld is appended rst, followed
by the high-order byte. The CRC high-order byte is the last
byte sent in the telegram.
7.8.8 Coil Register Addressing
In Modbus, all data is organized in coils and holding
registers. Coils hold a single bit, whereas holding registers
hold a 2 byte word (that is 16 bits). All data addresses in
Modbus telegrams are referenced to 0. The 1st occurrence
of a data item is addressed as item number 0. For example:
The coil known as coil 1 in a programmable controller is
addressed as coil 0000 in the data address eld of a
Modbus telegram. Coil 127 decimal is addressed as coil
007Ehex (126 decimal).
Holding register 40001 is addressed as register 0000 in the
data address eld of the telegram. The function code eld
already species a holding register operation. Therefore,
the 4XXXX reference is implicit. Holding register 40108 is
addressed as register 006Bhex (107 decimal).

The function code received in the query is
not an allowable action for the server (or
slave). This may be because the function
code is only applicable to newer devices
and was not implemented in the unit
selected. It could also indicate that the
server (or slave) is in the wrong state to
process a request of this type, for example
because it is not congured and is being
asked to return register values.

Code Name Meaning
2
Illegal data
address
The data address received in the query is
not an allowable address for the server (or
slave). More specically, the combination
of reference number and transfer length is
invalid. For a controller with 100 registers,
a request with oset 96 and length 4
succeeds, while a request with oset 96
and length 5 generates exception 02.
3
Illegal data
value
A value contained in the query data eld
is not an allowable value for server (or
slave). This indicates a fault in the
structure of the remainder of a complex
request, such as that the implied length is
incorrect. It does NOT mean that a data
item submitted for storage in a register
has a value outside the expectation of the
application program, since the Modbus
protocol is unaware of the signicance of
any value of any register.
4
Slave device
failure
An unrecoverable error occurred while the
server (or slave) was attempting to
perform the requested action.

How to Access Parameters
7.9.1 Parameter Handling
The PNU (parameter number) is translated from the
register address contained in the Modbus read or write
message. The parameter number is translated to Modbus
as (10 x parameter number) decimal. Example: Reading
parameter 3-12 Catch up/slow Down Value (16 bit): The
holding register 3120 holds the parameters value. A value
of 1352 (decimal) means that the parameter is set to
12.52%.
Reading parameter 3-14 Preset Relative Reference (32 bit):
The holding registers 3410 and 3411 hold the parameters
values. A value of 11300 (decimal), means that the
parameter is set to 1113.00.
For information on the parameters, size, and conversion
index, see chapter 6 Programming.
7.9.2 Storage of Data
The coil 65 decimal determines whether data written to
the frequency converter is stored in EEPROM and RAM (coil
65 = 1), or only in RAM (coil 65 = 0).
7.9.3 IND (Index)
Some parameters in the frequency converter are array
parameters, for example parameter 3-10 Preset Reference.
Since the Modbus does not support arrays in the holding
registers, the frequency converter has reserved the holding
register 9 as pointer to the array. Before reading or writing
an array parameter, set the holding register 9. Setting
holding register to the value of 2 causes all following read/
write to array parameters to be to the index 2.
7.9.4 Text Blocks
Parameters stored as text strings are accessed in the same
way as the other parameters. The maximum text block size
is 20 characters. If a read request for a parameter is for
more characters than the parameter stores, the response is
truncated. If the read request for a parameter is for fewer
characters than the parameter stores, the response is space
lled.
7.9.5 Conversion Factor
A parameter value can only be transferred as a whole
number. To transfer decimals, use a conversion factor.
7.9.6 Parameter Values
Standard data types
Standard data types are int 16, int 32, uint 8, uint 16, and
uint 32. They are stored as 4x registers (40001–4FFFF). The
parameters are read using function 03 hex read holding
registers. Parameters are written using the function 6 hex
preset single register for 1 register (16 bits), and the
function 10 hex preset multiple registers for 2 registers (32
bits). Readable sizes range from 1 register (16 bits) up to
10 registers (20 characters).
Non-standard data types
Non-standard data types are text strings and are stored as
4x registers (40001–4FFFF). The parameters are read using
function 03 hex read holding registers and written using
function 10 hex preset multiple registers. Readable sizes
range from 1 register (2 characters) up to 10 registers (20
characters).

8.3 Fuses and Circuit Breakers
Branch circuit protection
To prevent re hazards, protect the branch circuits in an
installation - switch gear, machines, and so on - against
short circuits and overcurrent. Follow national and local
regulations.
Short-circuit protection
Danfoss recommends using the fuses and circuit breakers
listed in Table 8.11 to protect service personnel or other
equipment in case of an internal failure in the unit or a
short circuit on the DC link. The frequency converter
provides full short-circuit protection in case of a short
circuit on the motor.
Overcurrent protection
Provide overload protection to avoid overheating of the
cables in the installation. Overcurrent protection must
always be carried out according to local and national
regulations. Circuit breakers and fuses must be designed
for protection in a circuit capable of supplying a maximum
of 100000 A
rms
(symmetrical), 480 V maximum.
UL/Non-UL compliance
To ensure compliance with UL or IEC 61800-5-1, use the
circuit breakers or fuses listed in Table 8.11.
Circuit breakers must be designed for protection in a
circuit capable of supplying a maximum of 10000 A
rms
(symmetrical), 480 V maximum.
NOTICE
In the event of malfunction, failure to follow the
protection recommendation may result in damage to the
frequency converter.

8.4 General Technical Data
Protection and features
Electronic motor thermal protection against overload.
Temperature monitoring of the heat sink ensures that the frequency converter trips if there is overtemperature.
The frequency converter is protected against short circuits between motor terminals U, V, W.
When a motor phase is missing, the frequency converter trips and issues an alarm.
When a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).
Monitoring of the DC-link voltage ensures that the frequency converter trips when the DC-link voltage is too low
or too high.
The frequency converter is protected against ground faults on motor terminals U, V, W.
