2.4 Product Overview
A frequency converter is an electronic motor controller
that converts AC mains input into a variable AC waveform
output. The frequency and voltage of the output are
regulated to control the motor speed or torque. The
frequency converter can vary the speed of the motor in
response to system feedback, such as position sensors on a
conveyor belt. The frequency converter can also regulate
the motor by responding to remote commands from
external controllers.
In addition, the frequency converter monitors the system
and motor status, issues warnings or alarms for fault
conditions, starts and stops the motor, optimizes energy
efficiency, and offers many more control, monitoring, and
efficiency functions. Operation and monitoring functions
are available as status indications to an outside control
system or serial communication network.

WARNING
CAUTION
EQUIPMENT HAZARD!
WIRING ISOLATION!
Rotating shafts and electrical equipment can be hazardous.
All electrical work must conform to national and local
electrical codes. It is strongly recommended that installation, start up, and maintenance be performed only by
trained and qualified personnel. Failure to follow these
guidelines could result in death or serious injury.
10

•
130BX370.10
For personal safety, comply with the following
requirements
Electronic controls equipment is connected to
hazardous mains voltage. Extreme care should be
taken to protect against electrical hazards when
applying power to the unit.
•
Run motor cables from multiple frequency
converters separately. Induced voltage from
output motor cables run together can charge
equipment capacitors even with the equipment
turned off and locked out.
•
Field wiring terminals are not intended to receive
a conductor one size larger.
3 3
Overload and Equipment Protection
An electronically activated function within the
frequency converter provides overload protection
for the motor. The overload calculates the level of
increase to activate timing for the trip (controller
output stop) function. The higher the current
draw, the quicker the trip response. The overload
provides Class 20 motor protection. See for
details on the trip function.
•
Because the motor wiring carries high frequency
current, it is important that wiring for mains,
motor power, and control are run separately. Use
metallic conduit or separated shielded wire. See
Illustration 3.3. Failure to isolate power, motor,
and control wiring could result in less than
optimum equipment performance.
•
All frequency converters must be provided with
short-circuit and over-current protection. Input
fusing is required to provide this protection, see
Illustration 3.4. If not factory supplied, fuses must
be provided by the installer as part of installation.
See maximum fuse ratings in 11.3.1 Protection.

3.4.2 Earth (Ground) Requirements
WARNING
EARTHING (GROUNDING) HAZARD!
For operator safety, it is important to earth (ground) the
frequency converter properly in accordance with national
and local electrical codes as well as instructions contained
within this document. Do not use conduit connected to
the frequency converter as a replacement for proper
grounding. Earth (ground) currents are higher than 3.5 mA.
Failure to earth (ground) the frequency converter properly
could result in death or serious injury.Earthing (grounding)
hazard
NOTE
It is the responsibility of the user or certified electrical
installer to ensure correct earthing (grounding) of the
equipment in accordance with national and local electrical
codes and standards.
•
Follow all local and national electrical codes to
earth (ground) electrical equipment properly.
•
Proper protective earthing (grounding) for
equipment with earth (ground) currents higher
than 3.5 mA must be established, see
3.4.2.1 Leakage Current (>3.5 mA).
•
A dedicated earth wire (ground wire) is required
for input power, motor power and control wiring.
•
Use the clamps provided with the equipment for
proper earth connections (ground connections).
•
Do not earth (ground) one frequency converter to
another in a “daisy chain” fashion.
•
Keep the earth (ground) wire connections as
short as possible.
•
Using high-strand wire to reduce electrical noise
is recommended.
•
Follow motor manufacturer wiring requirements.
Earthing (grounding) must be reinforced in one of the
following ways:
•
•
Earth (ground) wire of at least 10 mm2
Two separate earth (ground) wires both
complying with the dimensioning rules.
See EN 60364-5-54 § 543.7 for further information.
Using RCDs
Where residual current devices (RCDs)–also known as earth
leakage circuit breakers (ELCBs)–are used, comply with the
following: residual current devices (RCDs)
•
Use RCDs of type B only, which are capable of
detecting AC and DC currents.
•
Use RCDs with an inrush delay to prevent faults
due to transient earth currents.
•
Dimension RCDs according to the system configuration and environmental considerations.
3.4.2.1 Leakage Current (>3.5 mA)
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 depends on various system configurations
including RFI filtering, screened motor cables, and
frequency converter power.
EN/IEC61800-5-1 (Power Drive System Product Standard)
requires special care if the leakage current exceeds 3.5 mA.

Correct screening
The preferred method in most cases is to secure control
and serial communication cables with screening clamps
provided at both ends to ensure best possible high
frequency cable contact. If the earth (ground) potential
between the frequency converter and the PLC is different,
electric noise may occur that will disturb the entire system.
Solve this problem by fitting an equalizing cable next to
the control cable. Minimum cable cross section: 16 mm2.

associated with that terminal. See and for
terminals and associated parameters.
•
It is important to confirm that the control
terminal is programmed for the correct function.

3.6 Serial Communication
RS-485 is a two-wire bus interface compatible with multidrop 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. 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 converter 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 (ground) connection of the screen at
every node is important, including at high frequencies.
Thus, connect a large surface of the screen to earth
(ground), for example with a cable clamp or a conductive
cable gland. It may be necessary to apply potentialequalizing cables to maintain the same earth (ground)

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.

WARNING
HIGH VOLTAGE!
Frequency converters contain high voltage when
connected to AC mains. Installation, start-up and
maintenance should be performed by qualified personnel
only. Failure to perform installation, start-up and
maintenance by qualified personnel could result in death
or serious injury.
WARNING
UNINTENDED START!
When the frequency converter is connected to AC mains,
the motor may start at any time. The frequency converter,
motor, and any driven equipment must be in operational
readiness. Failure to be in operational readiness when the
frequency converter is connected to AC mains could result

7.1 Introduction
NOTE
•
A jumper wire may be required between terminal 12 (or
13) and terminal 37 for the frequency converter to operate
when using factory default programming values.
The examples in this section are intended as a quick
reference for common applications.
Parameter settings are the regional default values
unless otherwise indicated (selected in
0-03 Regional Settings)
•

9 Warnings and Alarms
9.2.3 Alarm Trip-lock
The frequency converter monitors the condition of its
input power, output, and motor factors as well as other
system performance indicators. A warning or alarm may
not necessarily indicate a problem internal to the
frequency converter itself. In many cases, it indicates failure
conditions from input voltage, motor load or temperature,
external signals, or other areas monitored by the frequency
converter’s internal logic. Be sure to investigate those areas
exterior to the frequency converter as indicated in the
alarm or warning.
An alarm that causes the frequency converter to trip-lock
requires that input power be cycled. The motor will coast
to a stop. The frequency converter logic will continue to
operate and monitor the frequency converter status.
Remove input power to the frequency converter and
correct the cause of the fault, then restore power. This
action puts the frequency converter into a trip condition as
described above and may be reset in any of those 4 ways.

Warnings and Alarms
VLT® Refrigeration Drive 110-250 kW Operating Instructions
WARNING/ALARM 7, DC overvoltage
If the intermediate circuit voltage exceeds the limit, the
frequency converter trips after a time.
9.5 Fault Messages
The warning/alarm information below defines each
warning/alarm condition, provides the probable cause for
the condition, and details a remedy or troubleshooting
procedure.
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 6-01 Live Zero Timeout Function. The signal on one
of the analog 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.
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.
•
Perform Input Terminal Signal Test.
WARNING/ALARM 3, No motor
No motor has been connected to the output of the
frequency converter.
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 14-12 Function at Mains
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.
54
Troubleshooting
• Connect a brake resistor
•
•
•
•
Extend the ramp time
Change the ramp type
Activate the functions in 2-10 Brake Function
Increase 14-26 Trip Delay at Inverter Fault
WARNING/ALARM 8, DC under voltage
If the intermediate circuit voltage (DC link) drops below
the under voltage limit, the frequency converter checks if a
24 V DC backup supply is connected. 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.
•
•
Perform input voltage test.
Perform soft charge circuit 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.
Troubleshooting
• Compare the output current shown on the LCP
with the frequency converter rated current.
•
Compare the output current shown on the LCP
with measured motor current.
•
Display the Thermal Drive Load on the LCP and
monitor the value. When running above the
frequency converter continuous current rating,
the counter should increase. When running below
the frequency converter continuous current
rating, the counter should decrease.
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 1-90 Motor Thermal Protection. 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
MG16F102 - VLT® is a registered Danfoss trademark

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 1-91 Motor
External Fan that it is selected.
•
Running AMA in 1-29 Automatic Motor Adaptation
(AMA) tunes the frequency converter to the
motor more accurately and reduces 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
1-90 Motor Thermal Protection.
Troubleshooting
• Check for motor overheating.
•
•
Check if the motor is mechanically overloaded.
Check that the thermistor is connected correctly
between either terminal 53 or 54 (analog voltage
input) and terminal 50 (+10 V supply) and that
the terminal switch for 53 or 54 is set for voltage.
Check 1-93 Thermistor Source selects terminal 53
or 54.
•
When using digital inputs 18 or 19, check that
the thermistor is connected correctly between
either terminal 18 or 19 (digital input PNP only)
and terminal 50.
•
If a KTY sensor is used, check for correct
connection between terminals 54 and 55
•
If using a thermal switch or thermistor, check that
the programming if 1-93 Thermistor Resource
matches sensor wiring.
•
If using a KTY sensor, check the programming of
1-95 KTY Sensor Type, 1-96 KTY Thermistor
Resource, and 1-97 KTY Threshold level match
sensor wiring.
WARNING/ALARM 12, Torque limit
The torque has exceeded the value in 4-16 Torque Limit
Motor Mode or the value in 4-17 Torque Limit Generator
Mode. 14-25 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
secs., 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.
Troubleshooting
•
Remove power and check if the motor shaft can
be turned.
•
Check that the motor size matches the frequency
converter.
•
Check parameters 1-20 through 1-25 for correct
motor data.
ALARM 14, Earth (ground) fault
There is current from the output phases to earth, either in
the cable between the frequency converter and the motor
or in the motor itself.
Troubleshooting:
• Remove power to the frequency converter and
repair the earth fault.

ALARM 64, Voltage Limit
The load and speed combination demands a motor
voltage higher than the actual DC link voltage.
WARNING/ALARM 65, Control card over temperature
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. Also, a
trickle amount of current can be supplied to the frequency
converter whenever the motor is stopped by setting
2-00 DC Hold/Preheat Current at 5% and 1-80 Function at
Stop
Troubleshooting
The heatsink temperature measured as 0° C could indicate
that the temperature sensor is defective, causing the fan
speed to increase to the maximum. If the sensor wire
between the IGBT and the gate drive card is disconnected,
this warning would result. Also, check the IGBT thermal
sensor.
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.

detected number of active power units.
Troubleshooting:
When replacing an F-frame module, this will occur if the
power specific data in the module power card does not
match the rest of the frequency converter. Please confirm
the spare part and its power card are the correct part
number.
77 WARNING, Reduced power mode
This warning indicates that the frequency converter is
operating in reduced power mode (i.e. less than the
allowed number of inverter sections). This warning will be
generated on power cycle when the frequency converter is
set to run with fewer inverters and will remain on.
ALARM 79, Illegal power section configuration
The scaling card is the incorrect part number or not
installed. Also MK102 connector on the power card could
not be installed.
ALARM 80, Drive initialised to default value

Protection and Features
• Electronic thermal motor protection against overload.
•
Temperature monitoring of the heatsink ensures that the frequency converter trips if the temperature reaches a
predefined level. An overload temperature cannot be reset until the temperature of the heatsink is below the
values stated in the tables on the following pages (Guideline - these temperatures may vary for different power
sizes, frame sizes, enclosure ratings etc.).
•
•
•
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.
Monitoring of the intermediate circuit voltage ensures that the frequency converter trips if the intermediate circuit
voltage is too low or too high.

2) American Wire Gauge.
3) Measured using 5 m screened motor cables at rated load and rated frequency.
4) The typical power loss is at nominal load conditions and expected to be within ±15% (tolerence relates to
variety in voltage and cable conditions). Values are based on a typical motor efficiency (eff2/eff3 border line).
Motors with lower efficiency will also add to the power loss in the frequency converter and opposite. If the
switching frequency is increased comed to the default setting, the power losses may rise significantly. LCP and

typical control card power consumptions are included. Further options and customer load may add up to 30 W to
the losses. (Though typical only 4 W extra for a fully loaded control card, or options for slot A or slot B, each).
Although measurements are made with state of the art equipment, some measurement inaccuracy must be
allowed for (±5%).

11.3 Fuse Specifications
11.3.1 Protection
Branch Circuit Protection:
In order to protect the installation against electrical and
fire hazard, all branch circuits in an installation, switch
gear, machines etc., must be short-circuited and overcurrent protected according to 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 below to protect
service personnel and equipment in case of an internal
failure in the frequency conveter. The frequency converter
provides full short-circuit protection in case of a shortcircuit on the motor output.
Over-current Protection:
Provide overload protection to avoid fire hazard due to
overheating of the cables in the installation. The frequency
converter is equipped with an internal over-current
protection that can be used for upstream overload
protection (UL-applications excluded). See 4-18 Current
Limit. Moreover, fuses or circuit breakers can be used to
provide the over-current protection in the installation.
Over-current protection must always be carried out
according to national regulations.
11 11
11.3.2 Non UL Compliance
If UL/cUL is not to be complied with, we recommend using
the following fuses, which will ensure compliance with
EN50178. In case of malfunction, not following the
recommendation may result in unnecessary damage to the
frequency converter.

11.3.4 Connection Tightening Torques
When tightening all electrical connections it is very
important to tighten with the correct torque. Too low or
too high torque results in a bad electrical connection. Use
a torque wrench to ensure correct torque. Always use a
torque wrench to tighten the bolts.
