brake resistor
The brake resistor is a module capable of absorbing the
brake power generated in regenerative braking. This
regenerative braking power increases the intermediate
circuit voltage and a brake chopper ensures that the
power is transmitted to the brake resistor.
initialising
If initialising is carried out (H-03 Restore Factory Settings),
the programmable parameters of the frequency converter
return to their default settings.
intermittent duty cycle
An intermittent duty rating refers to a sequence of duty
cycles. Each cycle consists of an on-load and an off-load
period. The operation can be either periodic duty or noneperiodic duty.
LCP
The local control panel (LCP) keypad makes up a complete
interface for control and programming of the frequency
converter. The control panel keypad is detachable and can
be installed up to 3 metres from the frequency converter,
in a front panel with the installation kit option.

Numerical local control panel LCP101.
on-line/off-line parameters
Changes to on-line parameters are activated immediately
after the data value is changed. Changes to off-line
parameters are not activated until [OK] is entered on the
LCP.
PID controller
The PID controller maintains the desired speed, pressure
and temperature by adjusting the output frequency to
match the varying load.
PCD
Process Data.
pulse input/incremental encoder
An external digital sensor used for feedback information of
motor speed and direction. Encoders are used for highspeed accuracy feedback and in high dynamic applications.
The encoder connection is either via terminal 32 or
encoder option MCB 102.
RCD
Residual Current Device. A device that disconnects a circuit
in case of an imbalance between an energised conductor
and ground. Also known as a ground fault circuit
interrupter (GFCI).
set-up
Parameter settings can be saved in four set-ups. Change
between the four parameter set-ups and edit one set-up,
while another set-up is active.
SFAVM
Switching pattern called Stator Flux oriented Asynchronous
Vector Modulation (F-37 Adv. Switching Pattern).
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.
thermistor
A temperature-dependent resistor placed where the
temperature is monitored (frequency converter or motor).
THD
Total Harmonic Distortion. A state of full harmonic
distortion.
trip
A state entered in fault situations. For example, if the
frequency converter is subject to an overtemperature or
when it is protecting the motor, process, or mechanism.
Restart is prevented until the cause of the fault has
disappeared and the trip state is cancelled by activating
Reset or, in some cases, by being programmed to reset
automatically. Do not use trip for personal safety.
trip locked
A state entered in fault situations when the frequency
converter is protecting itself and requires physical
intervention. For example, if the frequency converter is
subject to a short circuit on the output, it will enter trip
lock. A locked trip can only be cancelled by cutting off
mains, removing the cause of the fault, and reconnecting
the frequency converter.

The power factor indicates to what extent the frequency
converter imposes a load on the mains supply.
The lower the power factor, the higher the IRMS for the
same kW performance.
IRMS = I12 + I52 + I72 + . . + In2
In addition, a high power factor indicates that the different
harmonic currents are low.
The built-in DC coils produce a high power factor, which
minimizes the imposed load on the mains supply.

2.2 CE Labelling
2.2.2 What Is Covered
The EU "Guidelines on the Application of Council Directive
2004/108/EC" outline three typical situations for using a
frequency converter. See 2.2.3 Danfoss Frequency Converter
and CE Labelling and 2.2.4 Compliance with EMC Directive
2004/108/EC for CE labelling and EMC coverage.
1.
The frequency converter is sold directly to the
end-consumer. The frequency converter is for
example sold to a DIY market. The end-consumer
is a layman who uses the frequency converter
with a hobby machine, or household appliance.
For such applications, the frequency converter
must be CE labelled in accordance with the EMC
directive.
2.
The frequency converter is sold for installation in
a plant, such as a production plant or a heating/
ventilation plant designed and installed by trade
professionals. The frequency converter and the
finished plant do not have to be CE labelled
under the EMC directive. However, the unit must
comply with the basic EMC requirements of the
directive. Use components, appliances, and
systems that are CE labelled under the EMC
directive.
3.
The frequency converter is sold as part of a
complete system, such as an air-conditioning
system. The system is marketed as complete. The
complete system must be CE labelled in
accordance with the EMC directive. The
manufacturer can ensure CE labelling under the
EMC directive either by using CE labelled
components or by testing the EMC of the system.
The entire system need not be tested when only
CE labelled components are used.
2.2.1 CE Conformity and Labelling
What is CE conformity and labelling?
The purpose of CE labelling is to avoid technical trade
obstacles within EFTA and the EU. The EU has introduced
the CE label as a simple way of showing whether a
product complies with the relevant EU directives. The CE
label says nothing about the specifications or quality of
the product. Frequency converters follow three EU
directives:
The machinery directive (2006/42/EC)
Frequency converters with integrated safety function are
now falling under the machinery directive. Danfoss CElabels in accordance with the directive and issues a
declaration of conformity upon request. Frequency
converters without safety function do not fall under the
machinery directive. However, if a frequency converter is
supplied for use in a machine, we provide information on
safety aspects relating to the frequency converter.
The low-voltage directive (2006/95/EC)
Frequency converters must be CE labelled in accordance
with the low-voltage directive of January 1, 1997. The
directive applies to all electrical equipment and appliances
used in the 50–1000 V AC and the 75–1500 V DC voltage
ranges. Danfoss CE-labels in accordance with the directive
and issues a declaration of conformity upon request.
The EMC directive (2004/108/EC)
EMC is short for electromagnetic compatibility. The
presence of electromagnetic compatibility means that the
mutual interference between different components/
appliances does not affect the way the appliances work.
The EMC directive came into effect January 1, 1996.
Danfoss CE-labels in accordance with the directive and
issues a declaration of conformity upon request. To carry
out EMC-correct installation, see 5.7 EMC-correct Installation.
2.2.3 Danfoss Frequency Converter and CE
Labelling
CE labelling is a positive feature when used for its original
purpose: To facilitate trade within the EU and EFTA.

Introduction
VLT® HVAC Drive FC 102 Design Guide
However, CE labelling could cover many different specifications, so check the specifics of each CE label.
Danfoss CE labels the frequency converters in accordance
with the low-voltage directive. If the frequency converter is
installed correctly, compliance with the low-voltage
directive is guaranteed. Danfoss issues a declaration of
conformity that confirms our CE labelling in accordance
with the low-voltage directive.
The CE label also applies to the EMC directive if the
instructions for EMC-correct installation and filtering are
followed. On this basis, a declaration of conformity in
accordance with the EMC directive is issued.
For more on EMC, refer to 5.7 EMC-correct Installation.
Danfoss provides other types of assistance to obtain the
best EMC result.
2.2.4 Compliance with EMC Directive
2004/108/EC
Trade professionals use the frequency converter as a
complex component forming part of a larger appliance,
system, or installation. The responsibility for the final EMC
properties of the appliance, system, or installation rests
with the installer. As an aid to the installer, Danfoss has
prepared EMC installation guidelines for the power drive
system. Following EMC-correct installation instructions
ensures compliance with standards and test levels stated
for power drive systems. See 2.9 General aspects of EMC.
The frequency converter has been designed to meet the
IEC/EN 60068-2-3 standard, EN 50178 § 9.4.2.2 at 50 °C.
2.4 Aggressive Environments
A frequency converter contains many mechanical and
electronic components. All are to some extent vulnerable
to environmental effects.
CAUTION
Do not install the frequency converter in environments
with airborne liquids, particles, or gases capable of
affecting and damaging the electronic components.
Failure to take the necessary protective measures
increases the risk of stoppages, thus reducing the life of
the frequency converter.
16
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 can
corrode components and metal parts. In such
environments, use equipment with enclosure rating IP
54/55. As an extra protection, coated printed circuit boards
can be ordered as an option.
Airborne Particles such as dust can 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 IP
54/55 (NEMA 12) or an enclosure for IP 00/IP 20 (NEMA 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 damage the electronic
components. In such environments, mount the unit in an
enclosure with fresh air ventilation, keeping aggressive
gases away from the frequency converter.
Optional coating of printed circuit boards provides extra
protection in such areas.
NOTICE
2.3 Air Humidity
Degree of protection as per IEC 60529
Install the safe torque off function only in an enclosure
with an IP54 or higher rating (or equivalent environment).
Doing so will avoid cross faults and short circuits between
terminals, connectors, tracks, and safety-related circuitry
caused by foreign objects.
Mounting frequency converters in aggressive
environments increases the risk of stoppages and considerably reduces the life of the unit.
Before installing the frequency converter, observe existing
installations in the environment to check the ambient air
for liquids, particles, and gases. Typical indicators of
harmful airborne liquids are water, oil, or corrosion on
metal parts.
Excessive dust particle levels are often found on installation enclosures and existing electrical installations. One
indicator of aggressive airborne gases is blackening of
copper rails and cable ends on existing installations.
D and E enclosures have a stainless steel back-channel
option to provide more protection in aggressive
environments. Proper ventilation is still required for the
internal components of the drive. Contact Danfoss for
more information.

2.7.3 Example of Energy Savings
As seen in Illustration 2.5, the flow is controlled by
changing the RPM. Reducing the speed only 20% from the
rated speed also reduces the flow by 20%. The flow is
directly proportional to the RPM. The consumption of
electricity, however, is reduced by 50%.
If the system only runs at 100% flow a few days per year,
while the average is below 80% of the rated flow, the
amount of energy saved is even more than 50%.

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 softstarter is widely used. Such motor starters are not required
if a frequency converter is used.
As illustrated in Illustration 2.8, a frequency converter does
not consume more than rated current.
2.7.6 Better Control
If a frequency converter is used for controlling the flow or
pressure of a system, improved control is obtained.
A frequency converter can vary the speed of the fan or

While dampers and IGVs work to maintain a constant
pressure in the ductwork, a frequency converter solution
saves more energy and reduces the complexity of the
installation. Instead of creating an artificial pressure drop
or a decrease in fan efficiency, the frequency converter
decreases the speed of the fan to provide the flow and
pressure required by the system.
Centrifugal devices such as fans decrease the pressure and
flow they produce as their speed is reduced. Their power
consumption is reduced.
The return fan is frequently controlled to maintain a fixed
difference in airflow between the supply and return. The
advanced PID controller of the HVAC frequency converter
can be used to eliminate the need for more controllers.

setpoint or fixed difference between the supply and return
air flows.
CAV, or constant air volume systems are central ventilation
systems used to supply large common zones with the
minimum amounts of fresh tempered air. They preceded
VAV systems and are found in older multi-zoned
commercial buildings as well. These systems preheat fresh
air with air handling units (AHUs) that have heating coils.
Many are also used for air conditioning buildings and have
a cooling coil. Fan coil units are often used to help with
the heating and cooling requirements in the individual
zones.
2.7.16 The VLT Solution
With a frequency converter, significant energy savings can
be obtained while maintaining decent control of the
building. Temperature sensors or CO2 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 CO2 sensor
detects lower levels and decreases the supply fan speed.
The return fan modulates to maintain a static pressure
Cooling coil
Temperature control needs vary based on outside
temperature and number of people in the controlled zone.
As the temperature decreases below the setpoint, the
supply fan can decrease its speed. The return fan
modulates to maintain a static pressure setpoint.
Decreasing the air flow, reduces the energy used to heat
or cool the fresh air, resulting in further savings.
Several features of the Danfoss HVAC dedicated frequency
converter can be used to improve the performance of a
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 3-zone, 3 setpoint
PID controller which allows monitoring both temperature
and air quality. Even if the temperature requirement is
satisfied, the frequency converter maintains enough supply
air to satisfy the air quality sensor. The controller can
monitor and compare two feedback signals to control the
return fan by maintaining a fixed differential air flow
between the supply and return ducts.

2.7.17 Cooling Tower Fan
2.7.18 The VLT Solution
Cooling tower fans are used to cool condenser water in
water-cooled chiller systems. Water-cooled chillers provide
the most efficient means of creating chilled water. They
are as much as 20% more efficient than air cooled chillers.
Depending on climate, cooling towers are often the most
energy efficient method of cooling the condenser water
from chillers.
Cooling towers cool the condenser water by evaporation.
The condenser water is sprayed into the cooling tower
onto the fill to increase its surface area. The tower fan
blows air through the fill and sprayed water to aid in the
evaporation. Evaporation removes energy from the water,
dropping its temperature. The cooled water collects in the
basin of the cooling tower where it is pumped back into
the chiller condenser and the cycle is repeated.
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 off as needed.
With the Danfoss HVAC frequency converter, as the cooling
tower fans drop below a certain speed, the cooling effect
decreases. When using a gear-box to frequency control the
tower fan, a minimum speed of 40–50% could be 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.
130BB453.10
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 can cause vibrations. These
frequencies can easily be avoided by programming the
bypass frequency ranges in the frequency converter.

2.7.19 Condenser Pumps
2.7.20 The VLT Solution
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 condenser section and
releases it into the atmosphere in the cooling tower. These
systems provide the most efficient means of creating
chilled water. They are as much as 20% more efficient than
air cooled chillers.
Frequency converters can be added to condenser water
pumps instead of balancing the pumps with a throttling
valve or trimming the pump impeller.
2 2
130BB452.10
Using a frequency converter instead of a throttling valve
saves the energy that the valve would otherwise have
absorbed. This change can amount to savings of 15–20%
or more. Trimming the pump impeller is irreversible, so if
the conditions change and higher flow is required the
impeller must be replaced.

VLT® HVAC Drive FC 102 Design Guide
Primary pumps in a primary/secondary pumping system
can maintain a constant flow through devices that
encounter operation or control difficulties when exposed
to variable flow. The primary/secondary pumping
technique decouples the “primary” production loop from
the “secondary” distribution loop. Decoupling allows
devices such as chillers to obtain constant design flow and
operate properly while allowing the rest of the system to
vary in flow.
As the evaporator flow rate decreases in a chiller, the
chilled water begins to become over-chilled. As this
happens, the chiller attempts to decrease its cooling
capacity. If the flow rate drops far enough, or too quickly,
the chiller cannot shed its load sufficiently and the low
evaporator temperature safety trips the chiller, requiring a
manual reset. This situation is common in large installations, especially when two or more chillers in parallel are
installed if primary/secondary pumping is not used.
2.7.22 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. Two
control methods are common:
The first method uses a flow meter. Because the desired
flow rate is known and constant, a flow meter installed at
the discharge of each chiller can control the pump directly.
Using the PID controller, the frequency converter always
maintains the appropriate flow rate, even compensating
for the changing resistance in the primary piping loop as
chillers and their pumps are staged on and off.
The other method is local speed determination. The
operator simply decreases the output frequency until the
design flow rate is achieved.
Using a frequency converter to decrease the pump speed
is similar to trimming the pump impeller, but more
efficient. The balancing contractor simply decreases the
speed of the pump until the proper flow rate is achieved
and leaves the speed fixed. The pump operates at this
speed any time the chiller is staged on. Because the
primary loop lacks control valves or other devices that can
change the system curve, and the variance due to staging
pumps and chillers on and off is small, this fixed speed
remains appropriate. If the flow rate must be increased
later in the life of the system, the frequency converter can
simply increase the pump speed instead of requiring a
new pump impeller.

2.7.23 Secondary Pumps
2.7.24 The VLT Solution
Secondary pumps in a primary/secondary chilled water
pumping system are used to distribute the chilled water to
the loads from the primary production loop. The primary/
secondary pumping system is used to de-couple one
piping loop from another hydronically. In this case, the
primary pump maintains a constant flow through the
chillers, allowing the secondary pumps to vary flow,
increase control and save energy.
If the primary/secondary design concept is not used and a
variable volume system is designed, when the flow rate
drops far enough or too quickly, the chiller cannot shed its
load properly. The low evaporator temperature safety then
trips the chiller, requiring a manual reset. This situation is
common in large installations especially when two or more
chillers in parallel are installed.
While the primary/secondary system with 2-way valves
improves energy and system control, using frequency
converters increases the energy savings and control
potential further.
With the proper sensor location, the addition of frequency
converters allows the pumps to match their speed to the
system curve instead of the pump curve.
This eliminates wasted energy and most of the overpressurization, two-way valves can be subjected to.
As the monitored loads are reached, the 2-way valves close
down, increasing the differential pressure measured across
the load and two-way valve. As this differential 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 and
two way valve together under design conditions.

2.8.5 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 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.
2 2
130BA359.12
For example, consider a pump application where the speed of a pump is controlled so that the static pressure in a pipe is
constant. The desired 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 value to the frequency converter as a feedback
signal. If the feedback signal is greater than the setpoint reference, the frequency converter slows down to reduce the
pressure. Likewise, if the pipe pressure is lower than the setpoint reference, the frequency converter speeds up to increase
the pump pressure.

While the default values for the closed loop controller often provide satisfactory performance, the control of the system can
often be optimised by adjusting some of the closed loop controller parameters. It is also possible to auto tune the PI
constants.
2.8.6 Feedback Handling
Feedback handling can be configured to work with
applications requiring advanced control, such as multiple
setpoints and multiple feedbacks. Three types of control
are common.
Single Zone, Single Setpoint
Single zone single setpoint is a basic configuration.
Setpoint 1 is added to any other reference (if any, see
2.8.8 Reference Handling ) and the feedback signal is
selected using CL-20 Feedback Function.
Multi-Zone, Single Setpoint
Multi zone single setpoint uses 2 or 3 feedback sensors but
only 1 setpoint. The feedbacks can be added, subtracted
(only feedback 1 and 2) or averaged. In addition, the
maximum or minimum value could be used. Setpoint 1 is
used exclusively in this configuration.
frequency converter. [14] Multi Setpoint Maximum attempts
to keep all zones at or below their respective setpoints,
while [13] Multi Setpoint Min attempts to keep all zones at
or above their respective setpoints.
Example:
A 2 zone 2 setpoint application in which the Zone 1
setpoint is 15 bar and the feedback is 5.5 bar. Zone 2
setpoint is 4.4 bar and the feedback is 4.6 bar. If [14] Multi
Setpoint Max is selected, the setpoint and feedback of
Zone 2 are sent to the PID controller, since this has the
smaller difference (feedback is higher than setpoint,
resulting in a negative difference). If [13] Multi Setpoint Min
is selected, the setpoint and feedback of Zone 1 are sent
to the PID controller, since this has the larger difference
(feedback is lower than setpoint, resulting in a positive
difference).
If [13] Multi Setpoint Min is selected, the setpoint/feedback
pair with the largest difference controls the speed of the

In some applications it may be useful to convert the

pressure is proportional to flow, the square root of the
pressure signal yields a value proportional to the flow. This

2.8.11 Tuning the Closed Loop Controller
Once the closed loop controller has been set up, the
performance of the controller should be tested. In many
cases, its performance may be acceptable using the default
values of CL-93 PID Proportional Gain and CL-94 PID Integral
Time. However, in some cases it may be helpful to
optimize these parameter values to provide faster system
response while still controlling speed overshoot.
2.8.12 Manual PID Adjustment
38
1.
Start the motor.
2.
Set CL-93 PID 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
set-point reference to attempt to cause
oscillation.
3.
Reduce the PID proportional gain until the
feedback signal stabilizes. Reduce the proportional gain by 40-60%.
4.
Set CL-94 PID Integral Time to 20 sec. and reduce
it until the feedback signal begins to oscillate. If
necessary, start and stop the frequency converter
or make step changes in the set-point reference
to attempt to cause oscillation.
5.
Increase the PID integral time until the feedback
signal stabilizes. Increase of the integral time by
15-50%.
6.
CL-95 PID Differentiation Time should only be used
for fast-acting systems. The typical value is 25%
of CL-94 PID Integral Time. The differential
function should only be used when the setting of
the proportional gain and the integral time has
been fully optimized. Make sure that oscillations
of the feedback signal are sufficiently dampened
by the low-pass filter for the feedback signal
(parameters 6-16, 6-26, 5-54 or 5-59 as required).

2.9 General aspects of EMC
2.9.1 General Aspects of EMC Emissions
2 2
Electrical interference is usually conducted 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, motor cable, and motor.
Capacitive currents in the motor cable coupled with a high dU/dt from the motor voltage generate leakage currents.
The use of a screened motor cable increases the leakage current (see Illustration 2.26) because screened cables have higher
capacitance to earth than unscreened cables. If the leakage current is not filtered, causing greater interference on the mains
in the radio frequency range below approximately 5 MHz. Since the leakage current (I1) is carried back to the unit through
the screen (I 3), there is only a small electromagnetic field (I4) from the screened motor cable.

The screen reduces the radiated interference but increases the low-frequency interference on the mains. The motor cable
screen must be connected to the frequency converter enclosure as well as the motor enclosure. This is best done by using
integrated screen clamps so as to avoid twisted screen ends (pigtails). These increase the screen impedance at higher
frequencies, which reduces the screen effect and increases the leakage current (I4).
If a screened cable is used for fieldbus, relay, control cable, signal interface and brake, the screen must be mounted on the
enclosure at both ends. In some situations, however, it will be necessary to break the screen to avoid current loops.

If the screen is to be placed on a mounting plate for the frequency converter, the mounting plate must be made of metal,
because the screen currents have to be conveyed back to the unit. Moreover, ensure good electrical contact from the
mounting plate through the mounting screws to the frequency converter chassis.
Use of unscreened cables does not comply with all emission requirements, although the 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 generated by the control electronics. See 5.7 EMC-correct Installation for more information on EMC.

(transformer, cables). Consequently, in plants with a high
percentage of rectifier load, maintain harmonic currents at
a low level to avoid overload of the transformer and high
temperature in the cables.
Power sizes up to PK75 in T2 and T4 complies with IEC/EN

To ensure low harmonic currents, the frequency converter
is equipped with intermediate circuit coils as standard. This
normally reduces the input current IRMS 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.

2.9.7 Immunity Requirements
The immunity requirements for frequency converters
depend on the environment in which they are installed.
The requirements for the industrial environment are higher
than the requirements for the home and office
environments. All Danfoss frequency converters comply
with the requirements for the industrial environment and
consequently comply with the lower requirements for
home and office environment with a large safety margin.
To document immunity against electrical interference from
electrical phenomena, the following immunity tests have
been performed on a system consisting of a frequency
converter (with options if relevant), a screened control
cable and a control box with potentiometer, motor cable
and motor.
The tests were performed in accordance with the following
basic standards:

The functional galvanic isolation is for the 24 V back-up
option and for the standard bus interface.
2.10 Galvanic Isolation (PELV)
2.10.1 PELV - Protective Extra Low Voltage
WARNING
PELV (Protective Extra Low Voltage) offers protection
through extra low voltage. To ensure protection against
electric shock, use a PELV electrical supply and install 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 400 V.)
Galvanic (ensured) isolation is obtained by fulfilling
requirements for higher isolation and 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 below, also comply with the requirements for
higher isolation and the relevant test as described in EN
61800-5-1.
The PELV galvanic isolation is shown in six locations. See

WARNING
Touching the electrical parts could be fatal, even after
the equipment has been disconnected from mains.
Ensure that other voltage inputs, such as load sharing
(linkage of DC intermediate circuit), as well as the motor
connection for kinetic back-up, have been disocnnect.
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
specific unit.
Follow national and local codes regarding protective
earthing of equipment with a leakage current > 3,5 mA.
Frequency converter technology implies high frequency
switching at high power. This will generate a leakage
current in the earth connection. A fault current in the
frequency converter at the output power terminals might
contain a DC component, which can charge the filter
capacitors and cause a transient earth current.
The earth leakage current is made up of several contributions and depends on various system configurations
including RFI filtering, screened motor cables, and
frequency converter power.

2.12 Brake Function
EN/IEC61800-5-1 (Power Drive System Product Standard)
requires special care if the leakage current exceeds 3.5 mA.
Earth grounding must be reinforced in one of the
following ways:
In certain applications (in a tunnel or underground railway
station ventilation system, for example), it is desirable to
bring the motor to a stop faster than can be achieved
through controlling via ramp down or by free-wheeling. In
such applications, use dynamic braking with a brake
resistor to ensure that the energy is absorbed in the
resistor and not in the frequency converter.

Using RCDs
Where residual current devices (RCDs), also known as earth
leakage circuit breakers (ELCBs), are used, comply with the
following:
• Use only RCDs of type B, which are capable of
detecting AC and DC currents

2.12.1 Brake Resistor Selection
If the amount of kinetic energy transferred to the resistor
in each braking period is not known, calculate the average
power on the basis of the cycle time and braking time
(intermittent duty cycle). The resistor intermittent duty
cycle is an indication of the duty cycle at which the
resistor is active. Illustration 2.33 shows a typical braking
cycle.
The intermittent duty cycle for the resistor is calculated as

NOTICE
Check that the brake resistor can cope with a voltage of
820 V or 1130 V - unless Danfoss brake resistors are
used.
Danfoss recommends the brake resistance Rrec, which
guarantees that the frequency converter is able to brake at
the highest braking torque (Mbr(%)) of 110%. The formula
can be written as:
46
If a short circuit in the brake transistor occurs, power
dissipation in the brake resistor is only prevented by
using a mains switch or contactor to disconnect the
mains for the frequency converter. (The contactor can be
controlled by the frequency converter).
Do not touch the brake resistor as it can get
very hot during braking.
The brake resistance depends on the intermediate circuit
voltage (UDC).
The brake function of the frequency converter is settled in
3 areas of mains power supply:
ηmotor is typically at 0.90
η is typically at 0.98

The resistor brake circuit resistance selected should not
be higher than that recommended by Danfoss. If a brake
resistor with a higher ohmic value is selected, the
braking torque may not be achieved because there is a
risk that the frequency converter cuts out for safety
reasons.
2.12.3 Control with Brake Function
The brake is protected against short-circuiting of the brake
resistor, and the brake transistor is monitored to ensure
that short-circuiting of the transistor is detected. A relay/
digital output can be used for protecting the brake resistor
against overloading in connection with a fault in the
frequency converter.
In addition, the brake makes it possible to read out the
momentary power and the mean power for the latest 120
seconds. The brake can also monitor the power energizing
and make sure it does not exceed a limit selected in
B-12 Brake Power Limit (kW). In B-13 Braking Thermal
Overload, select the function to carry out when the power
transmitted to the brake resistor exceeds the limit set in
B-12 Brake Power Limit (kW).
NOTICE
Monitoring the brake power is not a safety function. A
thermal switch is required. The brake resistor circuit is
not earth leakage protected.
Over voltage control (OVC), for units without a brake
resistor, can be selected as an alternative brake function in

the value of 1-40 Back EMF at 1000 RPM, P-06 Base
Speed and P-39 Motor Poles.
If it is possible that the motor may overspeed, a
brake resistor is recommended.
NOTICE
OVC cannot be activated when running a PM motor
(when P-20 Motor Construction is set to [1] PM non
salient SPM).
2.12.4 Brake Resistor Cabling
EMC (twisted cables/shielding)
Twist the wires to reduces noise between the brake
resistor and the frequency converter.
Use a metal screen for enhanced EMC performance
2.13 Extreme Running Conditions
Short Circuit (Motor Phase – Phase)
The frequency converter is protected against short circuits
by current measurement in each of the three motor phases
or in the DC link. A short circuit between 2 output phases
causes an overcurrent in the inverter. The inverter is
turned off individually when the short circuit current
exceeds the permitted value (Alarm 16 Trip Lock).
See certificate in 2.6.3 Approvals & Certificates.
Output Switching
Output switching between the motor and the frequency
converter is permitted. Output switching does not damage
the frequency converter in any way but may cause fault
messages.
Motor-generated Over-voltage
The voltage in the intermediate circuit 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),
generating energy.
•
During deceleration ("ramp-down") if the moment
of inertia is high, the friction is low and the rampdown 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 may cause
higher DC link voltage.
•
Back-EMF (electromotive force) from PM motor
operation. If coasted at high rpm, the PM motor
back-EMF may potentially exceed the maximum
voltage tolerance of the frequency converter and
cause damage. To help prevent this, the value of
F-03 Max Output Frequency 1 is automatically
limited based on an internal calculation based on
WARNING
The frequency converter must be equipped
with a break chopper.
The control unit may attempt to correct the ramp if
possible (B-17 Over-voltage Control).
The inverter turns off to protect the transistors and the
intermediate circuit capacitors when a certain voltage level
is reached.
See parameters B-10 Brake Function and B-17 Over-voltage
Control to select the method used for controlling the
intermediate circuit voltage level.
NOTICE
OVC can not be activated when running a PM motor
(when P-20 Motor Construction is set to [1] PM non salient
SPM.
Mains Drop-out
During a mains drop-out, the frequency converter keeps
running until the intermediate circuit voltage drops below
the minimum stop level, which is typically 15% below the
lowest rated supply voltage. The mains voltage before the
drop-out and the motor load determine how long it takes
for the inverter to coast.
Static Overload in VVCplus mode
When the frequency converter is over loaded (the torque
limit in F-40 Torque Limiter (Driving)/F-41 Torque Limiter
(Braking) is reached), the controls reduce the output
frequency to reduce the load.
If the overload is excessive, a current may occur that
makes the frequency converter cut out after approx. 5-10
s.
Operation within the torque limit is limited in time (0-60 s.)
in SP-25 Trip Delay at Torque Limit.
2.13.1 Motor Thermal Protection
Motor thermal protection prevents the motor from
overheating. It is an electronic feature that simulates a
bimetal relay based on internal measurements. The characteristic is shown in Illustration 2.34
In Illustration 2.34, the X-axis is showing the ratio between
Imotor and Imotor nominal. The Y-axis is showing the time in
seconds before the ETR cuts off and trips the frequency
converter. The curves are showing the characteristic

It is clear that at lower speed the ETR cuts off at lower
heat due to less cooling of the motor. In that way, the
motor is protected from overheating even at low speed.

Summary
With the torque limit feature the motor is protected from
overload independent of the speed. With the ETR, the
motor is protected from overheating and there is no need
for any further motor protection. That means when the
motor is heated up, the ETR timer controls for how
longthe motor can run at the high temperature before it is
stopped to prevent overheating. If the motor is overloaded
without reaching the temperature where the ETR shuts of
the motor, the torque limit is protecting the motor and
application from being overloaded.
ETR is activated in F-10 Electronic Overload and controlled
in F-40 Torque Limiter (Driving). Set the time before the
torque limit warning trips the frequency converter in
SP-25 Trip Delay at Torque Limit.

PT100/1000 temperature sensors; one in front, one in the
back end bearing, and one in the motor windings. The
Danfoss option MCB 114 supports 2- or 3-wire sensors with
individual temperature limits for under/over temperature.
An auto detection of sensor type, PT100 or PT1000 takes
place at power up.
The option can generate an alarm if the measured
temperature is either below the low limit or above the
high limit specified by the user. The individual measured
temperature on each sensor input can be read out in the
display or by readout parameters. If an alarm occurs, the
relays or digital outputs can be programmed to be active
high by selecting [21] Thermal Warning in parameter group
5-**.
A fault condition has a common warning/alarm number
associated with it, which is Alarm/Warning 20, Temp. input
error. Any present output can be programmed to be active
in case the warning or alarm appears.

An anti-condensation heater can be installed inside the
frequency converter to prevent condensation from forming
inside the enclosure when the unit is turned off. The
heater is controlled by customer-supplied 230 V AC. For
best results, operate the heater only when the unit is not
running.
A 2.5 amp time-delay fuse, such as the Bussmann
LPJ-21/2SP, is recommended to protect the heater.
3.1.11.4 Brake Chopper
A brake chopper can be supplied for applications that
have a regenerative load. The brake chopper connects to a
brake resistor, which consumes the braking energy and
prevents an overvoltage fault on the DC bus. The brake
chopper is automatically activated when the DC bus
voltage exceeds a specified level, depending on the
nominal voltage of the frequency converter.

NOTICE
In applications where the motor is used as a brake, energy
is generated in the motor and sent back into the
frequency converter. If the energy cannot be transported
back to the motor, it increases the voltage in the
frequency converter DC line. In applications with frequent
braking and/or high inertia loads, this increase may lead to
an overvoltage trip in the frequency converter and finally a
shut down. Brake resistors are used to dissipate the excess
energy resulting from the regenerative braking. The
resistor is selected based on its ohmic value, its power
dissipation rate and its physical size. Danfoss offers a wide
variety of different resistors that are specifically designed
for Danfoss frequency converters.
Only one insulation resistance monitor can be
connected to each ungrounded (IT) system.

The high-speed switching of the frequency converter
produces some secondary effects, which influence the
motor and the enclosed environment. These side effects
are addressed by 2 different filter types, the dU/dt and the
sine-wave filter.
dU/dt filters
Motor insulation stresses are often caused by the
combination of rapid voltage and current increase. The
rapid energy changes can also be reflected back to the DC
line in the inverter and cause shut down. The dU/dt filter is
designed to reduce the voltage rise time and rapid energy
change in the motor. This reduction prevents premature
aging and flashover in the motor insulation. DU/dt filters
have a positive influence on the radiation of magnetic
noise in the cable that connects the frequency converter
to the motor. The voltage wave form is still pulse-shaped
but the dU/dt ratio is less than the installation without
filter.

3.1.14 Output Filters
Sine-wave filters
Sine-wave filters are designed to let only low frequencies
pass, resulting in a sinusoidal phase-to-phase voltage
waveform and sinusoidal current waveforms.
With the sinusoidal waveforms, special frequency converter
motors with reinforced insulation are no longer needed.
The acoustic noise from the motor is also reduced as a
consequence of the wave condition.
Besides the features of the dU/dt filter, the sine-wave filter
also reduces insulation stress and bearing currents in the
motor, thus leading to prolonged motor lifetime and
longer periods between services. Sine-wave filters enable
the use of longer motor cables in applications where the
motor is installed far from the frequency converter. The
length is limited because the filter does not reduce
leakage currents in the cables.

position in thettype code string, read from left to right.
4.1 Ordering Form
4.1.1 Drive Configurator
It is possible to design a frequency converter according to
the application requirements using the ordering number
system.
Order the frequency converter as either standard or with
integral options by sending a type code string describing
the product a to the local Danfoss sales office.
The type code is a string of characters describing the
configuration, for example:
FC-102N132KT4E21H1XGCXXXSXXXXAGBKCXXXXDX
From the online drive configurator, a customer can
configure the right frequency converter for a given
application and generate the type code string. The drive
configurator automatically generates an 8-digit sales
number to be delivered to the local sales office.
Another option is to establish a project list with several
products and send it to a Danfoss sales representative.

5.2.2 Motor Cables
See 8 General Specifications and Troubleshooting for
maximum dimensioning of motor cable cross-section and
length.
5 5
•
Use a screened/armoured motor cable to comply
with EMC emission specifications.
•
Keep the motor cable as short as possible to
reduce the noise level and leakage currents.
•
Connect the motor cable screen to both the
decoupling plate of the frequency converter and
the metal cabinet of the motor.
•
Make the screen connections with the largest
possible surface area (cable clamp) using the
installation devices in the frequency converter.
•
Avoid mounting with twisted screen ends
(pigtails), which will spoil high frequency
screening effects.
•
F14 requirements: Motor phase cable quantities must be
multiples of 4, resulting in 4, 8, 12, or 16, to obtain an
equal number of wires attached to each inverter module
terminal. The wires are required to be equal length within
10% between the inverter module terminals and the first
common point of a phase. The recommended common
point is the motor terminals.
Output junction box requirements: The length, minimum
2.5 meters, and quantity of cables must be equal from
each inverter module to the common terminal in the
junction box.
NOTICE
If it is necessary to split the screen to install a
motor isolator or motor relay, the screen must be
continued with the lowest possible HF
impedance.
F frame Requirements
F1/F3 requirements: Motor phase cable quantities must be
multiples of 2, resulting in 2, 4, 6, or 8, to obtain an equal
number of wires attached to both inverter module
terminals. The cables are required to be equal length
within 10% between the inverter module terminals and the
first common point of a phase. The recommended
common point is the motor terminals.
F2/F4 requirements: Motor phase cable quantities must be
multiples of 3, resulting in 3, 6, 9, or 12, to obtain an equal
number of wires attached to each inverter module
terminal. The wires are required to be equal length within
10% between the inverter module terminals and the first
common point of a phase. The recommended common
point is the motor terminals.
F8/F9 requirements: The cables are required to be equal
length within 10% between the inverter module terminals
and the first common point of a phase. The recommended
common point is the motor terminals.
F10/F11 requirements: Motor phase cable quantities must
be multiples of 2, resulting in 2, 4, 6, or 8, to obtain an
equal number of wires attached to both inverter module
terminals. The cables are required to be equal length
within 10% between the inverter module terminals and the
first common point of a phase. The recommended
common point is the motor terminals.
F12/F13 requirements: Motor phase cable quantities must
be multiples of 3, resulting in 3, 6, 9, or 12, to obtain an
equal number of wires attached to each inverter module
100
terminal. The wires are required to be equal length within
10% between the inverter module terminals and the first
common point of a phase. The recommended common
point is the motor terminals.
If a retrofit application requires an unequal number of
wires per phase, consult the factory for requirements
and documentation or use the top/bottom entry side
cabinet busbar option.
5.2.3 Electrical Installation of Motor Cables
Screening of cables: Avoid installation with twisted screen
ends (pigtails). They spoil the screening effect at higher
frequencies. If it is necessary to break the screen to install
a motor isolator or motor contactor, continue the screen at
the lowest possible HF impedance.
Connect the motor cable screen to both the decoupling
plate of the frequency converter and to the metal housing
of the motor.
Make the screen connections with the largest possible
surface area (cable clamp) using the installation devices in
the frequency converter.
If it is necessary to split the screen to install a motor
isolator or motor relay, continue the screen with the
lowest possible HF impedance.
Cable-length and cross-section: The frequency converter
has been tested with a given length of cable and a given
cross-section of that cable. If the cross-section is increased,
the cable capacitance, and thus the leakage current, may
increase. Reduce the cable length accordingly. Keep the
motor cable as short as possible to reduce the noise level
and leakage currents.
Switching frequency: When frequency converters are used
together with sine-wave filters to reduce the acoustic noise
from a motor, the switching frequency must be set
according to the sine-wave filter instruction in
14-01 Switching Frequency.
MG16C102 - Rev. 2013-08-20
VLT® HVAC Drive FC 102 Design Guide
Aluminum conductors: Do not use aluminum conductors.
Terminals can accept aluminum conductors but the
conductor surface has to be clean and the oxidation
removed and sealed by neutral, acid-free grease before the
conductor is connected.
Additionally, the terminal screw must be retightened after
two days due to the softness of the aluminum. Maintain a
gas tight joint connection to prevent oxidation.

5.2.7 Power Connections
Make the screen connections with the largest possible
surface area (cable clamp) by using the installation devices
within the frequency converter.
NOTICE
Cable-length and cross-section
The frequency converter has been EMC tested with a given
length of cable. Keep the motor cable as short as possible
to reduce the noise level and leakage currents.
All cabling must comply with national and local
regulations on cable cross-sections and ambient
temperature. UL applications require 75 °C copper
conductors. Non-UL applications can use 75 °C and 90 °C
copper conductors.
The power cable connections are situated as shown in
Illustration 5.51. Dimensioning of cable cross section must
comply with the current ratings and local legislation. See
8.1 General Specifications for correct dimensioning of motor
cable cross-section and length.
Switching frequency
When frequency converters are used together with sinewave filters to reduce the acoustic noise from a motor, the
switching frequency must be set according to the
instructions in 14-01 Switching Frequency.
Term. 96 97
no.
U
For protection of the frequency converter, use the
recommended fuses unless the unit has built-in fuses.
Recommended fuses are listed in the Operating
Instructions. Ensure that proper fusing complies with local
regulations.
The mains connection is fitted to the mains switch if
included.

requirements are not complied with. Use a screened/
armoured motor cable to comply with EMC emission
specifications. For more information, see 5.7 EMC-correct
Installation.

Screening of cables
Avoid installation with twisted screen ends (pigtails). They
spoil the screening effect at higher frequencies. If it is
necessary to break the screen to install a motor isolator or
contactor, continue the screen at the lowest possible HF
impedance.
Connect the motor cable screen to both the de-coupling
plate of the frequency converter and the metal housing of
the motor.

Notes:
Parallel connection shown. A single 3-phase cable may be used with sufficient carrying capability. Install shorting bus bars.
2) 6-pulse connection eliminates the harmonics reduction benefits of the 12-pulse rectifier.
3) Suitable for IT and TN mains connection.
4) If one of the 6-pulse modular rectifiers becomes inoperable, it is possible to operate the frequency converter at reduced
load with a single 6-pulse rectifier. Contact Danfoss for reconnection details.
5) No paralleling of mains cabling is shown here. A 12-pulse frequency converter used as a 6-pulse should have mains cables
of equal numbers and lengths.

NOTICE
NOTICE
Use mains cables of equal length ( ±10%) and the same
wire size for all three phases on both rectifier sections.
In motors without phase insulation paper or other
insulation reinforcement suitable for operation with
voltage supply, fit a sine-wave filter on the output of the
frequency converter.
Screening of Cables
Avoid installation with twisted screen ends (pigtails). They
spoil the screening effect at higher frequencies. If it is
necessary to break the screen to install a motor isolator or
motor contactor, the screen must be continued at the
lowest possible HF impedance.
Connect the motor cable screen to both the de-coupling
plate of the frequency converter and the metal housing of
the motor.
Make the screen connections with the largest possible
surface area (cable clamp) using the supplied installation
devices within the frequency converter.
Cable-Length and Cross-Section
Keep the motor cable as short as possible to reduce the
noise level and leakage currents.
Switching Frequency
When frequency converters are used together with sinewave filters to reduce the acoustic noise from a motor, set
the switching frequency according to the instruction in
14-01 Switching Frequency.

5.2.9 Fuses
NOTICE
All fuses mentioned are maximum fuse sizes.
Branch circuit protection:
To protect the installation against electrical and fire hazard,
all branch circuits in an installation, switch gear or
machine, must be short-circuit and overcurrent protected
according to the national/international regulations.
Short circuit protection:
The frequency converter must be protected against shortcircuit to avoid electrical or fire hazard. Danfoss
recommends using the fuses mentioned in Table 5.65 and
Table 5.66 to protect service personnel or other equipment
in case of an internal failure. The frequency converter
provides full short circuit protection in a short-circuit on
the motor output.
Over-current protection:
To avoid fire hazard due to overheating of the cables,
provide over-current protection in accordance with
national regulations. The frequency converter is equipped
with an internal over current protection that can be used
for upstream overload protection (UL-applications
excluded). See F-43 Current Limit. Fuses must be designed
for protection in a circuit capable of supplying a maximum
of 100,000 Arms (symmetrical), 500 V/600 V maximum.

NOTICE
Safe Torque Off (STO) input is available with STO function
only
Control cables must be screened.
Very long control cables and analog signals occasionally
result in 50/60 Hz earth loops due to noise from mains
supply cables.
Use a clamp from the accessory bag to connect the screen
to the frequency converter de-coupling plate for control
cables.
130BT340.10
In this case, break the screen or insert a 100 nF capacitor
between screen and chassis.
The digital and analog inputs and outputs must be
connected separately to the common inputs (terminal 20,
55, 39) to avoid ground currents from both groups to
affect other groups. For example, switching on the digital
input disturbs the analog input signal.

WARNING
When running high voltage tests of the entire installation, interrupt the mains and motor connection if the
leakage currents are too high.
5.6.2 Safety Earth Connection
The frequency converter has a high leakage current and
must be earthed appropriately for safety reasons according
to EN 50178.

WARNING
effectiveness at high frequencies. Use low
impedance cable clamps or EMC cable glands
instead.
The earth leakage current from the frequency converter
exceeds 3.5 mA. To ensure a good mechanical
connection from the earth cable to the earth connection
(terminal 95), the cable cross-section must be at least 10
mm2 or 2 rated earth wires terminated separately.
•
Avoid using unscreened/unarmoured motor or
control cables inside cabinets housing the
frequency converter, whenever possible.
Leave the screen as close to the connectors as possible.
5.7.1 Electrical Installation - EMC
Precautions
Follow the EMC-correct guidelines below to comply with
EN 61800-3 First environment. If the installation is in EN
61800-3 Second environment, deviation from these
guidelines is allowed but not recommended. See also
paragraphs 2.2 CE Labelling, 2.9 General aspects of EMC and
2.9.3 EMC Test Results (Emission)
Good engineering practice to ensure EMC-correct
electrical installation:
• Use only braided screened/armoured motor
cables and braided screened/armoured control
cables. The screen should provide a minimum
coverage of 80%. The screen material is metal,
typically copper, aluminium, steel or lead. There
are no special requirements for the mains cable.
•
•
•
Installations using rigid metal conduits do not
require screened cable, but the motor cable must
be installed in conduit separate from the control
and mains cables. Full connection of the conduit
from the drive to the motor is required. The EMC
performance of flexible conduits varies. Contact
the manufacturer for more information.
Connect the screen/armour/conduit to earth at
both ends for motor cables as well as for control
cables. In some cases, it is not possible to
connect the screen in both ends. In such cases,
connect the screen at the frequency converter.
See also 5.7.1 Electrical Installation - EMC
Precautions
Avoid terminating the screen/armour with twisted
ends (pigtails). It increases the high frequency
impedance of the screen, which reduces its
Illustration 5.104 shows an example of an EMC-correct
electrical installation of an IP 20 frequency converter. The
frequency converter is fitted in an installation cabinet with
an output contactor and connected to a PLC, which is
installed in a separate cabinet.
If the installation is not carried out according to the
guideline and if unscreened cables and control wires are
used, some emission requirements are not complied with,
although the immunity requirements are fulfilled.

5.7.2 Use of EMC-Correct Cables
Danfoss recommends braided screened/armoured cables to
optimise EMC immunity of the control cables and the EMC
emission from the motor cables.
The ability of a cable to reduce the incoming and
outgoing radiation of electric noise depends on the
transfer impedance (ZT). The screen of a cable is normally
designed to reduce the transfer of electric noise; however,
a screen with a lower transfer impedance (ZT) value is
more effective than a screen with a higher transfer
impedance (ZT).
152
Transfer impedance (ZT) is rarely stated by cable manufacturers but it is often possible to estimate transfer
impedance (ZT) by assessing the physical design of the
cable.
Transfer impedance (ZT) can be assessed by the
following:
• The conductibility of the screen material.
•
The contact resistance between the individual

noise that disturbs the entire system is possible.
Fit an equalising cable, next to the control cable.
Minimum cable cross-section: 16 mm 2.

Using long control cables sometimes causes
50/60 Hz earth loops. Connect one end of the

leads short).
e.
Cables for serial communication
Eliminate low-frequency noise currents between
two frequency converters by connecting one end
of the screen to terminal 61. This terminal is
connected to earth via an internal RC link. Use

6.1.4 Automatic Motor Adaptation (AMA)
6.1.5 Smart Logic Control
AMA is an algorithm to measure the electrical motor
parameters on a motor at standstill. This means that AMA
itself does not supply any torque.
AMA is useful when commissioning systems and
optimising the adjustment of the applied motor. This
feature is particularly used where the default setting does
not apply to the connected motor.
P-04 Auto Tune allows a choice of complete AMA with
determination of all electrical motor parameters or reduced
AMA with determination of the stator resistance Rs only.
The duration of a total AMA varies from a few minutes on
small motors to more than 15 minutes on large motors.
In applications where a PLC is generating a simple
sequence the Smart Logic Controller (SLC) can take over
elementary tasks from the main control.
SLC is designed to act from event send to or generated in
the frequency converter. The frequency converter then
performs the pre-programmed action.
Limitations and preconditions:
• For the AMA to determine the motor parameters
optimally, enter the correct motor nameplate
data in P-07 Motor Power [kW] to P-08 Motor
Rotation Check.
•
•
AMA can only be performed if the rated motor
current is minimum 35% of the rated output
current of the frequency converter. AMA can be
carried out on up to one oversized motor.
•
It is possible to carry out a reduced AMA test
with a sine-wave filter installed. Avoid carrying
out a complete AMA with a sine-wave filter. If an
overall setting is required, remove the sine-wave
filter while running a total AMA. After completion
of the AMA, reinsert the sine-wave filter.
•
If motors are coupled in parallel, use only
reduced AMA if any.
•
Avoid running a complete AMA when using
synchronous motors. If using synchronous
motors, run a reduced AMA and manually set the
extended motor data. The AMA function does not
apply to permanent magnet (PM) motors.
•
•
156
For the best adjustment of the frequency
converter, carry out AMA on a cold motor.
Repeated AMA runs may heat the motor,
resulting in an increase of the stator resistance,
Rs. Normally, this is not critical.
6.1.6 Smart Logic Control Programming
The Smart Logic Control (SLC) is essentially a sequence of
user-defined actions (see LC-52 Logic Controller Action)
executed by the SLC when the associated user-defined
event (see LC-51 Logic Controller Event) is evaluated as
TRUE by the SLC.
Events and actions are each numbered and are linked in
pairs called states. This means that when event [1] is
fulfilled (attains the value TRUE), action [1] is executed.
After this, the conditions of event [2] is evaluated and if
evaluated TRUE, action [2] is executed and so on. Events
and actions are placed in array parameters.
Only one event is evaluated at any time. If an event is
evaluated as FALSE, nothing happens (in the SLC) during
the present scan interval and no other events are
evaluated. When the SLC starts, it evaluates event [1] (and
only event [1]) each scan interval. Only when event [1] is
evaluated TRUE, the SLC executes action [1] and starts
evaluating event [2].
It is possible to program from 0 to 20 events and actions.
When the last event/action has been executed, the
sequence starts over again from event [1]/action [1].
Illustration 6.4 shows an example with 3 events/actions:
130BA062.13

Application Examples
Start

The frequency converter does not produce motor
torque during an AMA. During an AMA, it is
imperative that the application does not force the
motor shaft to run, which is known to happen
with wind milling in ventilation systems, for
example. This disturbs the AMA function.

Cascade Controller
Illustration 6.7 BASIC Cascade Controller
The BASIC cascade controller is used for pump applications
where a certain pressure (“head”) or level needs to be
maintained over a wide dynamic range. Running a large
pump at variable speed over a wide range is not an ideal
solution because of low pump efficiency and because
there is a practical limit of about 25% rated full load speed
for running a pump.
158
In the BASIC cascade controller, the frequency converter
controls a variable speed motor as the variable speed
pump (lead) and can stage up to 2 additional constant
speed pumps on and off. By varying the speed of the
initial pump, variable speed control of the entire system is
provided. This maintains constant pressure while
eliminating pressure surges, resulting in reduced system
stress and quieter operation.
Fixed Lead Pump
The motors must be of equal size. The BASIC cascade
controller allows the frequency converter to control up to
3 equal size pumps using the two built-in relays. When the
variable pump (lead) is connected directly to the drive, the
other 2 pumps are controlled by the 2 built-in relays.
When lead pump alternations is enabled, pumps are
connected to the built-in relays and the frequency
converter is capable of operating 2 pumps.
Lead Pump Alternation
When the motors are of equal size, lead pump alteration
enables the frequency converter to cycle the drive
between the pumps in the system (maximum of 2 pumps).
In this operation, the run time between pumps is
equalized, reducing the required pump maintenance and
increasing reliability and lifetime of the system. The
alternation of the lead pump can take place at a command
signal or at staging (adding another pump).
The command can be a manual alternation or an
alternation event signal. If the alternation event is selected,
MG16C102 - Rev. 2013-08-20
Application Examples
VLT® HVAC Drive FC 102 Design Guide
the lead pump alternation takes place every time the
event occurs. Selections include whenever an alternation
timer expires, at a predefined time of day or when the
lead pump goes into sleep mode. Staging is determined
by the actual system load.
After a time delay, the relay for the fixed speed pump cuts
in (staged) and this pump becomes the new lead pump.
The new lead pump ramps up to maximum speed and
then down to minimum speed. When ramping down and
reaching the staging frequency, the old lead pump is now
cut in (staged) on the mains as the new fixed speed pump.
A separate parameter limits alternation to take place only
if total capacity required is > 50%. Total pump capacity is
determined as lead pump plus fixed speed pump
capacities.
If the lead pump has been running at minimum frequency
(fmin) for a programmed amount of time, with a fixed
speed pump running, the lead pump contributes little to
the system. When the programmed value of the timer
expires, the lead pump is removed, avoiding a water
circulation problem.
Bandwidth Management
In cascade control systems, the desired system pressure is
kept within a bandwidth rather than at a constant level to
avoid frequent switching of fixed speed pumps. The
staging bandwidth provides the required bandwidth for
operation. When a large and quick change in system
pressure occurs, the override bandwidth overrides the
staging bandwidth to prevent immediate response to a
short duration pressure change. An Override Bandwidth
Timer can be programmed to prevent staging until the
system pressure has stabilized and normal control
established.
6.1.10 System Status and Operation
If the lead pump goes into sleep mode, the function is
displayed in the LCP. It is possible to alternate the lead
pump on a Sleep Mode condition.
When the cascade controller is enabled, the operation
status for each pump and the cascade controller is
displayed on the LCP. Information displayed includes:

When the Cascade Controller is enabled and running
normally and the frequency converter issues a trip alarm,
the system head is maintained by staging and destaging
fixed speed pumps. To prevent frequent staging and

speed bandwidth is used instead of the staging
bandwidth.

With lead pump alternation enabled, a maximum of 2
pumps are controlled. At an alternation command, the
lead pump will ramp to minimum frequency (fmin) and
after a delay will ramp to maximum frequency (fmax). When
the speed of the lead pump reaches the destaging
frequency, the fixed speed pump is cut out (de-staged).
The lead pump continues to ramp up and then ramps
down to a stop and the 2 relays are cut out.

De-stage at no-flow ensures that all fixed speed
pumps are stopped individually until the no-flow

RS-485 is a 2-wire bus interface compatible with multi-drop
network topology, i.e. 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 one network segment.
Repeaters divide network segments. Note that 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 screened
twisted pair (STP) cable for bus cabling, and always follow
good common installation practice.
Low-impedance earth connection of the screen at every
node is important. Connect a large surface of the screen to
earth with a cable clamp or a conductive cable gland. If
needed, apply potential-equalizing cables to maintain the
same earth 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
screened motor cable.

The following EMC precautions are recommended in order
to achieve interference-free operation of the RS-485
network.
Observe relevant national and local regulations regarding
protective earth connection. Keep the RS-485 communication cable away from motor and brake resistor cables to
avoid coupling of high frequency noise from one cable to
another. Normally a distance of 200 mm (8 inches) is
sufficient, but it is best to keep the greatest possible
distance between the cables, especially where cables run
in parallel over long distances. When crossing is
unavoidable, the RS-485 cable must cross motor and brake
resistor cables at a 90° angle.
Illustration 7.4 Crossing Cables
7.2 FC Protocol Overview
The FC protocol, also referred to as FC bus or standard
bus, is the Danfoss standard fieldbus. It defines 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 first being requested to
do so, and direct message transfer between the individual
slaves is not possible. Communications occur in the halfduplex mode.
The master function cannot be transferred to another node
(single-master system).
The physical layer is RS-485, thus utilizing the RS-485 port
built into the frequency converter. The FC protocol
supports different telegram formats:
•
•
•

A long format of 16 bytes that also includes a
parameter channel.

7.4.1 Content of a Character (byte)
Each character transferred begins with a start bit. Eight
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 1’s in the 8 data bits and the parity bit in total.
A stop bit completes a character, thus consisting of 11 bits
in all.

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. This permits a
range of control options, including controlling the setpoint
of the frequency converter when its internal PID controller
is used.
Each telegram has the following structure:
1.
Start character (STX)=02 Hex
2.
A byte denoting the telegram length (LGE)
3.
A byte denoting the frequency converter address
(ADR)
A number of data bytes (variable, depending on the type

The 10 represents the fixed characters, while the “n’” is variable (depending on the length of the text).
7.4.4 Address (ADR)
Two different address formats are used.
The address range of the frequency converter is either 1-31 or 1-126.
1. Address format 1-31:
Bit 7 = 0 (address format 1-31 active)
7 7
Bit 6 is not used
Bit 5 = 1: Broadcast, address bits (0-4) are not used
Bit 5 = 0: No Broadcast
Bit 0-4 = frequency converter address 1-31
2. 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 first 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 (master=>slave) and response telegrams (slave=>master).
The 3 types of telegram are:

Bits no. 0-11 transfer parameter numbers. The function of
the relevant parameter is defined in the parameter
description in the Programming Guide.
The parameter value block consists of 2 words (4 bytes),
and the value depends on the defined 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 it from the
master to the slave.
7.4.9 Index (IND)
The index is used together with the parameter number to
read/write-access parameters with an index. The index
consists of 2 bytes, a low byte and a high byte.
Only the low byte is used as an index.
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 not a numerical value but several data options,
select the data value by entering the value in the PWE
block. Serial communication is only capable of reading
parameters containing data type 9 (text string).

the length of the telegram is variable, and the texts are of
different lengths. The length is defined in the second byte
of the telegram, LGE. When using text transfer the index
character indicates whether it is a read or a write
command.

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 Modbus RTU (Remote Terminal Unit) is designed to
communicate with any controller that supports the
interfaces defined in this document. It is assumed that the
user has full knowledge of the capabilities and limitations
of the controller.
7.6.3 Modbus RTU Overview
Regardless of the type of physical communication
networks, the Modbus RTU Overview describes the process
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 message fields.
During communications over a Modbus RTU network, the
protocol determines how each controller:
•
•
•
•
Learns its device address
Recognizes a message addressed to it
Determines which actions to take
Extracts any data or other information contained
in the message
If a reply is required, the controller constructs the reply
message and sends it.
Controllers communicate using a master-slave technique in
which only one device (the master) can initiate
transactions (called queries). The other devices (slaves)
respond by supplying the requested data to the master, or
by taking the action requested in the query.
The master can address individual slaves, or can initiate a
broadcast message to all slaves. Slaves return a message
(called 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’s query by placing
into it the device (or broadcast) address, a function code
defining the requested action, any data to be sent, and an
error-checking field. The slave’s response message is also
constructed using Modbus protocol. It contains fields
confirming the action taken, any data to be returned, and
an error-checking field. If an error occurs in receipt of the

message, or if the slave is unable to perform the requested
action, the slave will construct an error message, and send
it in response, or a time-out occurs.

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

VLT® HVAC Drive FC 102 Design Guide
7.8.3 Start/Stop Field
7.8.6 Data Field
Messages start with a silent period of at least 3.5 character
intervals. This is implemented as a multiple of character
intervals at the selected network baud rate (shown as Start
T1-T2-T3-T4). The first field 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 message. A new message can begin after this period.
The data field is constructed using sets of 2 hexadecimal
digits, in the range of 00 to FF hexadecimal. These are
made up of one RTU character. The data field of messages
sent from a master to slave device contains additional
information, which the slave must use to take the action
defined by the function code. This can include items such
as:
The entire message frame must be transmitted as a
continuous stream. If a silent period of more than 1.5
character intervals occurs before completion of the frame,
the receiving device flushes the incomplete message and
assumes that the next byte is the address field of a new
message. Similarly, if a new message begins before 3.5
character intervals after a previous message, the receiving
device considers it a continuation of the previous message.
This causes a time-out (no response from the slave), since
the value in the final CRC field is not valid for the
combined messages.
7.8.4 Address Field
The address field of a message 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 field of the message.
When the slave sends its response, it places its own
address in this address field to let the master know which
slave is responding.
7.8.5 Function Field
The function field of a message frame contains 8 bits. Valid
codes are in the range of 1-FF. Function fields are used to
send messages between master and slave. When a
message is sent from a master to a slave device, the
function code field tells the slave what kind of action to
perform. When the slave responds to the master, it uses
the function code field to indicate either a normal (errorfree) 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 significant bit set to
logic 1. The slave places a unique code into the data field
of the response message, telling the master what kind of
error occurred, or the reason. Refer to 7.8.11 Modbus
Exception Codes for more information.

Coil or register addresses
Quantity of items to be handled
Count of actual data bytes in the field
7.8.7 CRC Check Field
Messages include an error-checking field, operating on the
basis of a Cyclical Redundancy Check (CRC) method. The
CRC field checks the contents of the entire message. It is
applied regardless of any parity check method used for the
individual characters of the message. The CRC value is
calculated by the transmitting device, which appends the
CRC as the last field in the message. The receiving device
recalculates a CRC during receipt of the message and
compares the calculated value to the actual value received
in the CRC field. If the 2 values are unequal, a bus time-out
results. The error-checking field contains a 16-bit binary
value implemented as two 8-bit bytes. When this is done,
the low-order byte of the field is appended first, followed
by the high-order byte. The CRC high-order byte is the last
byte sent in the message.
7.8.8 Coil Register Addressing
In Modbus, all data are organized in coils and holding
registers. Coils hold a single bit, whereas holding registers
hold a 2-byte word (i.e. 16 bits). All data addresses in
Modbus messages are referenced to zero. The first
occurrence of a data item is addressed as item number
zero. For example: The coil known as ‘coil 1’ in a
programmable controller is addressed as coil 0000 in the
data address field of a Modbus message. Coil 127 decimal
is addressed as coil 007EHEX (126 decimal).
Holding register 40001 is addressed as register 0000 in the
data address field of the message. The function code field
already specifies a ‘holding register’ operation. Therefore,
the ‘4XXXX’ reference is implicit. Holding register 40108 is
addressed as register 006BHEX (107 decimal).

7.8.11 Modbus Exception Codes
7.9.2 Storage of Data
For a full explanation of the structure of an exception code
response, refer to 7.8.5 Function Field.
The Coil 65 decimal determines whether data written to
the frequency converter are stored in EEPROM and RAM
(coil 65 = 1) or only in RAM (coil 65 = 0).
Cod
e
Name
Meaning
1
Illegal
function
The function code received in the query is
not an allowable action for the server (or
slave). This can 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, because it is
not configured and is being asked to return
7.9.3 IND
register values, for example.
2
Illegal data
address
The data address received in the query is
not an allowable address for the server (or
slave). More specifically, the combination of
reference number and transfer length is
invalid. For a controller with 100 registers, a
request with offset 96 and length 4
succeeds, a request with offset 96 and
length 5 generates exception 02.
3
4
Illegal data
value
A value contained in the query data field 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 specifically 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 significance of
any particular value of any particular
register.
Slave device An unrecoverable error occurred while the
failure
server (or slave) was attempting to perform
the requested action.
Table 7.21 Modbus Exception Codes
7.9 Parameter Access
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.
174
The array index is set in Holding Register 9 and used when
accessing array parameters.
7.9.4 Text Blocks
Parameters stored as text strings are accessed in the same
way as 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
filled.
7.9.5 Conversion Factor
Since a parameter value can only be transferred as a whole
number, use a conversion factor to transfer decimals.
7.9.6 Parameter Values
Standard Data Types
Standard data types are int16, int32, uint8, uint16 and
uint32. They are stored as 4x registers (40001 – 4FFFF). The
parameters are read using function 03HEX "Read Holding
Registers." Parameters are written using the function 6HEX
"Preset Single Register" for 1 register (16 bits), and the
function 10HEX "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 03HEX "Read Holding Registers" and written
using function 10HEX "Preset Multiple Registers." Readable
sizes range from 1 register (2 characters) up to 10 registers
(20 characters).
7.10 Examples
The following examples illustrate various Modbus RTU
commands. If an error occurs, refer to 8 General Specifications and Troubleshooting.

Speed reference value is transmitted to the frequency converter in a relative value in %. The value is transmitted in the form
of a 16-bit word; in integers (0-32767) the value 16384 (4000 Hex) corresponds to 100%. Negative figures are formatted by
means of 2’s complement. The Actual Output frequency (MAV) is scaled in the same way as the bus reference.

3) The typical power loss is at normal conditions and expected to be within ± 15% (tolerance relates to variety in voltage and cable conditions.)
These values are based on a typical motor efficiency (IE2/IE3 border line). Lower efficiency motors add to the power loss in the frequency
converter and the opposite is also true. If the switching frequency is raised from nominal, the power losses rise significantly. LCP and typical
control card power consumptions are included. Further options and customer load can add up to 30 W to the losses (though typically only 4 W
extra for a fully loaded control card or options for slot A or slot B, each).
4) Measured using 5 m screened motor cables at rated load and rated frequency.
5) Wiring terminals on N132, N160, and N315 frequency converters cannot receive cables one size larger.

1) For type of fuse, consult the Operating Instructions
2) American Wire Gauge
3) The typical power loss is at normal conditions and expected to be within ± 15% (tolerance relates to variety in voltage and cable conditions.)
These values are based on a typical motor efficiency (eff2/eff3 border line). Lower efficiency motors add to the power loss in the frequency
converter and the opposite is also true. If the switching frequency is raised from nominal, the power losses rise significantly. LCP and typical
control card power consumptions are included. Further options and customer load can add up to 30 W to the losses (though typically only 4 W
extra for a fully loaded control card or options for slot A or slot B, each)
4) Measured using 5 m screened motor cables at rated load and rated frequency

Protection and Features
•
•
Electronic thermal motor protection against overload.
•
•
•
The frequency converter is protected against short-circuits on motor terminals U, V, W.
If a mains phase is missing, the frequency converter trips or issues a warning (depending on the load).
•
The frequency converter is protected against earth faults on motor terminals U, V, W.
Temperature monitoring of the heatsink ensures that the frequency converter trips when the temperature reaches
95 °C ± 5 °C. An overload temperature cannot be reset until the temperature of the heatsink is below 70 °C ± 5 °C
(Guideline - these temperatures vary for different power sizes and enclosures). The frequency converter has an
auto derating function to prevent its heatsink reaching 95 °C.
Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the intermediate circuit
voltage is too low or high.

Mains voltage low/mains drop-out:
During low mains voltage or a mains drop-out, the frequency converter continues until the intermediate circuit voltage drops
below the minimum stop level, which corresponds typically to 15% below the lowest rated supply voltage. Power-up and full
torque cannot be expected at mains voltage lower than 10% below the lowest rated supply voltage.

converter depends on magnetizing level. In general, the
efficiency is just as good as with mains operation. The
efficiency of the motor depends on the type of motor.
In the range of 75-100% of the rated torque, the efficiency
of the motor is practically constant, both when it is
controlled by the frequency converter and when it runs
directly on mains.
In small motors, the influence from the U/f characteristic
on efficiency is marginal. However, in motors from 11 kW
and up, the advantages are significant.
8.2 Efficiency
Efficiency of the Frequency Converter ( ηVLT )
The load on the frequency converter has little effect on its
efficiency. In general, the efficiency is the same at the
rated motor frequency fM,N, even if the motor supplies
100% of the rated shaft torque or only 75%.
In general, the switching frequency does not affect the
efficiency of small motors. Motors from 11 kW up have
their efficiency improved (1-2%) because the sine shape of
the motor current is almost perfect at high switching
frequency.
The efficiency of the frequency converter does not change
even if other U/f characteristics are chosen.
However, the U/f characteristics influence the efficiency of
the motor.
Efficiency of the system (ηSYSTEM)
To calculate the system efficiency, the efficiency of the
frequency converter (ηVLT) is multiplied by the efficiency of
the motor (ηMOTOR):
ηSYSTEM = ηVLT x ηMOTOR
The efficiency declines slightly when the switching
frequency is set to a value of above 5 kHz. The efficiency is
also slightly reduced if the mains voltage is 480 V, or if the
motor cable is longer than 30 m.

If the motor cable is long (100 m), the rise time and peak
voltage increase.
8.4 Peak Voltage on Motor
When a transistor in the inverter bridge switches, the
voltage across the motor increases by a du/dt ratio
depending on:
•
•
In motors without phase insulation paper or other
insulation reinforcement suitable for operation with
voltage supply (such as a frequency converter), fit a sinewave filter on the output of the frequency converter.
Motor cable
To obtain approximate values for cable lengths and
voltages not mentioned below, use the following
guidelines:
-
type
-
cross-section
-
length
-
screened/unscreened
Inductance
The natural induction causes an overshoot UPEAK in the
motor voltage before it stabilizes itself at a level
depending on the voltage in the intermediate circuit. The
rise time and the peak voltage UPEAK affects the service life
of the motor. If the peak voltage is too high, motors
without phase coil insulation are especially affected. If the
motor cable is short (a few metres), the rise time and peak
voltage are lower.
1.
Rise time increases/decreases proportionally with
cable length.
2.
UPEAK = DC link voltage x 1.9
(DC link voltage = Mains voltage x 1.35).

Table 8.15 Derating Tables for Frequency Converters Rated 525–690 V (T7)
The frequency converter constantly checks for critical levels
of internal temperature, load current, high voltage on the
intermediate circuit and low motor speeds. As a response
to a critical level, the frequency converter can adjust the
switching frequency and/or change the switching pattern
in order to ensure the performance of the frequency
converter. The capability to automatically reduce the
output current extends the acceptable operating
conditions even further.
Below 1000 m altitude, no derating is necessary but above
1000 m the ambient temperature (TAMB) or max. output
current (Iout) should be derated in accordance with
Illustration 8.3.

An alternative is to lower the ambient temperature at high
altitudes and thereby ensure 100% output current at high
altitudes. As an example of how to read the graph, the
situation at 2 km is elaborated. At a temperature of 45 °C
(TAMB, MAX - 3.3 K), 91% of the rated output current is
available. At a temperature of 41.7 °C, 100% of the rated
output current is available.

An alternative is to reduce the load level of the motor by
selecting a larger motor. However, the design of the
frequency converter puts a limit to the motor size.
Variable (Quadratic) Torque Applications (VT)
In VT applications such as centrifugal pumps and fans,
where the torque is proportional to the square of the
speed and the power is proportional to the cube of the
speed, there is no need for additional cooling or derating
of the motor.
95
In Illustration 8.6, the typical VT curve is below the
maximum torque with de-rating and maximum torque
with forced cooling at all speeds.

8.5.5 Derating for Running at Low Speed
When a motor is connected to a frequency converter, it is
necessary to check that the cooling of the motor is
adequate.
The level of heating depends on the load on the motor, as
well as the operating speed and time.
Constant torque applications (CT mode)
A problem may occur at low RPM values in constant
torque applications. A motor may overheat at low speeds
due to less cooling air from the motor integral fan.
If the motor runs continuously at an RPM value lower than
half of the rated value, additional air-cooling is needed. A
motor designed for this type of operation may also be
used.

Note 1) Over-syncronous speed operation will result in the
available motor torque decreasing inversely proportional with
the increase in speed. This must be considered during the
design phase to avoid over-loading of the motor.
Table 8.16 Legend to Illustration 8.6
8.6 Troubleshooting
A warning or alarm is signalled by the relevant LED on the
front of the frequency converter and indicated by a code
on the display.
A warning remains active until its cause is terminated.
Under certain circumstances, operation of the motor may
still continue. Warning messages are sometimes critical,
but not always.
In the event of an alarm, the frequency converter trips.
Reset alarms to restart operation once their cause has
been rectified.
MG16C102 - Rev. 2013-08-20
General Specifications and ...
VLT® HVAC Drive FC 102 Design Guide
CAUTION
There are 4 ways to restart after an event:
1.
Pressing [RESET] on the LCP.
2.
Via a digital input with the “Reset” function.
3.
Via serial communication/optional fieldbus.
4.
By resetting automatically using the Auto Reset
function, which is a default setting for VLT® HVAC
Drive. See H-04 Auto-Reset (Times) in the VLT®
HVAC Programming Guide
Alarms that are trip-locked offer additional protection,
meaning that the mains supply must be switched off
before the alarm can be reset. After switching mains
supply back on, the frequency converter is no longer
blocked and may be reset as described above once the
cause has been rectified. Alarms that are not trip-locked
can also be reset using the automatic reset function in
H-04 Auto-Reset (Times) (Warning: automatic wake-up is
possible)
If a warning and alarm is marked against a code in
Table 8.17, this means that either a warning occurs
before an alarm, or it can be specified whether it is a
warning or an alarm that is to be displayed for a given
fault.
This is possible, for instance, in F-10 Electronic Overload.
After an alarm or trip, the motor carries on coasting, and
the alarm and warning flash on the frequency converter.
Once the problem has been rectified, only the alarm
continues flashing.
NOTICE
After pressing [RESET] , press the [Auto On] or
[Hand On] button to restart the motor.
If an alarm cannot be reset, the reason may be that its
cause has not been rectified, or the alarm is trip-locked
(see also Table 8.17).

A trip is the action when an alarm has appeared. The trip
will coast the motor and can be reset by pressing the reset
button or making a reset by a digital input (parameter
group 5-1* [1]). The original event that caused an alarm
cannot damage the frequency converter or cause
dangerous conditions. A trip lock is an action when an
alarm occurs, which may cause damage to frequency
converter or connected parts. A trip lock situation can only
be reset by a power cycling.

Table 8.25 Extended Status Word 2
8.6.4 Warning and Alarm Introduction
The warning/alarm information below defines each
warning/alarm condition, provides the probable cause for
the condition, and details a remedy or troubleshooting
procedure.
Test procedures are described in the service manual and
should only be performed by qualified personnel.
WARNING 1, 10 Volts low
The control card voltage is below 10 V from terminal 50.
Remove some of the load from terminal 50, as the 10 V
supply is overloaded. Max. 15 mA or minimum 590 Ω.
This condition can be caused by a short in a connected
potentiometer or improper wiring of the potentiometer.
Troubleshooting
Remove the wiring from terminal 50. If the warning clears,
the problem is with the customer wiring. If the warning
does not clear, replace the control card.
WARNING/ALARM 2, Live zero error
This warning or alarm only appears if programmed by the
user in AN-01 Live Zero Timeout Function. The signal on one
of the analogue inputs is less than 50% of the minimum
value programmed for that input. Broken wiring or faulty
device sending the signal can cause this condition.
MG16C102 - Rev. 2013-08-20

General Specifications and ...
VLT® HVAC Drive FC 102 Design Guide
Troubleshooting
Check connections on all the analog input
terminals:
•
Control card terminals 53 and 54 for
signals, terminal 55 common.
•
MCB 101 terminals 11 and 12 for signals,
terminal 10 common.
•
MCB 109 terminals 1, 3, 5 for signals,
terminals 2, 4, 6 common).
Check that the frequency converter programming
and switch settings match the analog signal type.
WARNING/ALARM 4, Mains phase loss
A phase is missing on the supply side, or the mains
voltage imbalance is too high. This message also appears
for a fault in the input rectifier on the frequency converter.
Options are programmed at SP-12 Function at Line
Imbalance.
Troubleshooting
Check the supply voltage and supply currents to the
frequency converter.
WARNING 5, DC link voltage high
The intermediate circuit voltage (DC) is higher than the
high voltage warning limit. The limit is dependent on the
frequency converter voltage rating. The unit is still active.
WARNING 6, DC link voltage low
The intermediate circuit voltage (DC) is lower than the low
voltage warning limit. The limit is dependent on the
frequency converter voltage rating. The unit is still active.
WARNING/ALARM 7, DC overvoltage
If the intermediate circuit voltage exceeds the limit, the
frequency converter trips after a time.
Troubleshooting
Connect a brake resistor
Change the ramp type
Activate the functions in B-10 Brake Function
Increase SP-26 Trip Delay at Drive Fault
WARNING/ALARM 8, DC under voltage
If the intermediate circuit voltage (DC link) drops below
the under voltage limit, the frequency converter checks for
a 24 V DC backup supply. If no 24 V DC backup supply is
connected, the frequency converter trips after a fixed time
delay. The time delay varies with unit size.
Troubleshooting
Check that the supply voltage matches the
frequency converter voltage.
206
Display the thermal drive load on the LCP and
monitor the value. When running above the
frequency converter continuous current rating,
the counter increases. When running below the
frequency converter continuous current rating,
the counter decreases.
See 8.5 Special Conditions for more details if a high
switching frequency is required.
WARNING/ALARM 10, Motor overload temperature
According to the electronic thermal protection (ETR), the
motor is too hot. Select whether the frequency converter
gives a warning or an alarm when the counter reaches
100% in F-10 Electronic Overload. The fault occurs when the
motor is overloaded by more than 100% for too long.
Troubleshooting
Check for motor overheating.
Check if the motor is mechanically overloaded.
Check that the motor current set in P-03 Motor
Current is correct.
Ensure that motor data in parameters 1-20
through 1-25 are set correctly.
If an external fan is in use, check in F-11 Motor
External Fan that it is selected.
Extend the ramp time
Perform soft charge circuit test.
Troubleshooting
Compare the output current on the LCP with the
frequency converter rated current.
Compare the output current on the LCP with
measured motor current.
Perform input terminal signal test.
Perform input voltage test.
WARNING/ALARM 9, Inverter overload
The frequency converter is about to cut out because of an
overload (too high current for too long). The counter for
electronic, thermal inverter protection gives a warning at
98% and trips at 100%, while giving an alarm. The
frequency converter cannot be reset until the counter is
below 90%.
The fault is that the frequency converter is overloaded by
more than 100% for too long.
Run AMA in P-04 Auto Tune tune the frequency
converter to the motor more accurately and
reduce thermal loading.
WARNING/ALARM 11, Motor thermistor over temp
The thermistor might be disconnected. Select whether the
frequency converter gives a warning or an alarm in
F-10 Electronic Overload.
Troubleshooting
Check for motor overheating.
Check if the motor is mechanically overloaded.
When using terminal 53 or 54, check that the
thermistor is connected correctly between either
terminal 53 or 54 (analogue voltage input) and
terminal 50 (+10 V supply) and that the terminal
MG16C102 - Rev. 2013-08-20
General Specifications and ...
VLT® HVAC Drive FC 102 Design Guide
switch for 53 or 54 is set for voltage. Check that
F-12 Motor Thermistor Input selects terminal 53 or
54.
Record the value of the following parameters and contact
Danfoss.
15-40 FC Type
When using digital inputs 18 or 19, check that
the thermistor is connected correctly between

WARNING/ALARM 12, Torque limit
The torque has exceeded the value in F-40 Torque Limiter
(Driving) or the value in F-41 Torque Limiter (Braking).
SP-25 Trip Delay at Torque Limit can change this from a
warning only condition to a warning followed by an alarm.
Troubleshooting
If the motor torque limit is exceeded during ramp
up, extend the ramp up time.
If the generator torque limit is exceeded during
ramp down, extend the ramp down time.
If torque limit occurs while running, possibly
increase the torque limit. Be sure the system can
operate safely at a higher torque.
Check the application for excessive current draw
on the motor.
WARNING/ALARM 13, Over current
The inverter peak current limit (approximately 200% of the
rated current) is exceeded. The warning lasts about 1.5 s,
then the frequency converter trips and issues an alarm.
This fault may be caused by shock loading or fast
acceleration with high inertia loads. If extended mechanical
brake control is selected, trip can be reset externally.

WARNING 60, External interlock
A digital input signal indicates a fault condition external to
the frequency converter. An external interlock has
commanded the frequency converter to trip. Clear the
external fault condition. To resume normal operation,
apply 24 V DC to the terminal programmed for external
interlock. Reset the frequency converter.
WARNING 62, Output frequency at maximum limit
The output frequency has reached the value set in
F-03 Max Output Frequency 1. Check the application to
determine the cause. Possibly increase the output
frequency limit. Be sure the system can operate safely at a
higher output frequency. The warning clears when the
output drops below the maximum limit.

The cutout temperature of the control card is 80 °C.
Troubleshooting
• Check that the ambient operating temperature is
within limits
Check for clogged filters
Check fan operation
Check the control card
WARNING 66, Heatsink temperature low
The frequency converter is too cold to operate. This
warning is based on the temperature sensor in the IGBT
module.
Increase the ambient temperature of the unit. A trickle
amount of current can be supplied to the frequency
converter whenever the motor is stopped by setting
B-00 DC Hold Current at 5% and H-80 Function at Stop.
ALARM 67, Option module configuration has changed
One or more options have either been added or removed
since the last power-down. Check that the configuration
change is intentional and reset the unit.
ALARM 68, Safe Stop activated
Loss of the 24 V DC signal on terminal 37 has caused the
unit to trip. To resume normal operation, apply 24 V DC to
terminal 37 and reset the unit.
210
Troubleshooting
Check that the ambient operating temperature is
within limits.
Check for clogged filters.
WARNING 59, Current limit

ALARM 69, Power card temperature
The temperature sensor on the power card is either too
hot or too cold.
Check fan operation.
Check the power card.
ALARM 70, Illegal frequency converter configuration
The control card and power card are incompatible. Contact
the supplier with the type code of the unit from the
nameplate and the part numbers of the cards to check
compatibility.
ALARM 71, PTC 1 safe torque off
Safe torque off has been activated from the MCB 112 PTC
thermistor card (motor too warm). Normal operation can
resume when the MCB 112 applies 24 V DC to T-37 again
(when the motor temperature reaches an acceptable level)
and when the digital input from the MCB 112 is
deactivated. When that happens, a reset signal is sent (via
Bus, Digital I/O, or by pressing [RESET]).
ALARM 72, Dangerous failure
Safe torque off with trip lock. The dangerous failure alarm
is issued if the combination of safe torque off commands
is unexpected. This occurs if the MCB 112 VLT PTC
Thermistor Card enables X44/10 but safe torque off is not
enabled. Furthermore, if the MCB 112 is the only device
using safe torque off (specified through selection [4] or [5]
in 5-19 Terminal 37 Safe Stop), an unexpected combination
is activation of safe torque off without the X44/10 being
activated. Table 8.26 summarizes the unexpected
combinations that lead to Alarm 72. Note that if X44/10 is
activated in selection 2 or 3, this signal is ignored.
However, the MCB 112 is still able to activate safe torque
off.
ALARM 80, Drive initialised to default value
Parameter settings are initialised to default settings after a
manual reset. Reset the unit to clear the alarm.
ALARM 92, No flow
A no-flow condition has occurred. AP-23 No-Flow Function
is set for alarm. Troubleshoot the system and reset the
frequency converter after the fault has been cleared.
ALARM 93, Dry pump
A no-flow condition in the system with the frequency
converter operating at high speed may indicate a dry
pump. AP-26 Dry Pump Function is set for alarm.
Troubleshoot the system and reset the frequency converter
after clearing the fault.
ALARM 94, End of curve
Feedback is lower than the set point. This may indicate
leakage in the system. AP-50 End of Curve Function is set
for alarm. Troubleshoot the system and reset the frequency
converter after the fault has been cleared.
MG16C102 - Rev. 2013-08-20
General Specifications and ...
VLT® HVAC Drive FC 102 Design Guide
ALARM 95, Broken belt

Motor start has been delayed due to short-cycle
protection. AP-76 Interval between Starts is enabled.
Troubleshoot the system and reset the frequency converter
after the fault has been cleared.
WARNING 97, Stop delayed
Stopping the motor has been delayed due to short cycle
protection. AP-76 Interval between Starts is enabled.
Troubleshoot the system and reset the frequency converter
after the fault has been cleared.
WARNING 98, Clock fault
Time is not set or the RTC clock has failed. Reset the clock
in K-70 Date and Time.
WARNING/ALARM 104, Mixing fan fault
The fan monitor checks that the fan is spinning at drive
power-up or whenever the mixing fan is turned on. If the
fan is not operating, then the fault is annunciated. The
mixing-fan fault can be configured as a warning or an
alarm trip by parameter 14-53 (Fan Monitor).
8 8
Troubleshooting Cycle power to the frequency converter
to determine if the warning/alarm returns.
WARNING 200, Fire mode
This indicates the frequency converter is operating in fire
mode. The warning clears when fire mode is removed. See
the fire mode data in the alarm log.
WARNING 201, Fire mode was active
This indicates the frequency converter had entered fire
mode. Cycle power to the unit to remove the warning. See
the fire mode data in the alarm log.
WARNING 202, Fire mode limits exceeded
While operating in fire mode one or more alarm conditions
have been ignored which would normally trip the unit.
Operating in this condition voids unit warranty. Cycle
power to the unit to remove the warning. See the fire
mode data in the alarm log.
WARNING 203, Missing motor
With a frequency converter operating multi-motors, an
under-load condition was detected. This could indicate a
missing motor. Inspect the system for proper operation.
WARNING 204, Locked rotor
With a frequency converter operating multi-motors, an
overload condition was detected. This could indicate a
locked rotor. Inspect the motor for proper operation.
WARNING 250, New spare part
