A frequency converter is an electronic motor controller
that converts DC 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.
The frequency converter offers many control, monitoring
and efficiency functions such as:
Monitoring the system and motor status
•
Issuing warnings or alarms for fault conditions
•
Starting and stopping the motor
•
Optimising energy efficiency
•
Operation and monitoring functions are available as status
indications to an outside control system or serial communication network.

protection.
If frequency converter rating is less than
•
motor, full motor output cannot be
achieved.
3.3
Mechanical Installation
3.3.1 Cooling
Provide top and bottom clearance for air cooling.
•
Generally, 225 mm (9 in) is required.
Improper mounting can result in overheating and
•
reduced performance.
Consider derating for temperatures starting
•
between 45 °C (113 °F) and 50 °C (122 °F) and
elevation 1000 m (3300 ft) above sea level. See
VLT® Refrigeration Drive FC 103 Design Guide for
detailed information.
The high-power frequency converters utilise a backchannel cooling concept that removes heat sink cooling
air. Approximately 90% of the heat is lead out of the back
channel of the frequency converters. The back-channel air
can be redirected from the panel or room using one of the
kits below.
Duct cooling
A back-channel cooling kit is available to direct the heat
sink cooling air out of the panel when an IP20/chassis
frequency converter is installed in a Rittal enclosure. Use of
this kit reduces the heat in the panel and smaller door fans
can be specified on the enclosure.
Cooling out the back (top and bottom covers)
The back-channel cooling air can be ventilated out of the
room so that the heat from the back channel is not
dissipated into the control room.
NOTICE
A door fan(s) is required on the enclosure to remove the
heat not contained in the back channel of the frequency
converters and any additional losses generated by other
components inside the enclosure. Calculate the total
required air flow so that the appropriate fans can be
selected. A cooling clearance of 225 mm is required
above the frequency converter.
Airflow
Secure the necessary airflow over the heat sink. The flow
rate is shown in Table 3.2.

This section contains detailed instructions for wiring the
frequency converter. The following tasks are described:
Wiring the motor to the frequency converter
•
output terminals.
Wiring the AC mains to the frequency converter
•
input terminals.
Connecting control and serial communication
•
wiring.
After power has been applied, checking input
•
and motor power; programming control terminals
for their intended functions.
WARNING
EQUIPMENT HAZARD
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 are
performed only by trained and qualified personnel.
Failure to follow these guidelines could result in death or
serious injury.
33
CAUTION
WIRING ISOLATION
Run input power, motor wiring, and control wiring in 3
separate metallic conduits, or use separated shielded
cable for high frequency noise isolation. Failure to isolate
power, motor, and control wiring could result in less
than optimum performance of the frequency converter
and associated equipment.
For safety, comply with the following requirements:
Electronic controls equipment is connected to
•
hazardous mains voltage. Take extreme 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.
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
chapter 9 Warnings and Alarms 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 3.24. 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 overcurrent protection. Input
fusing is required to provide this protection, see
Illustration 3.25. If not factory supplied, fuses must
be provided by the installer as part of installation.
See maximum fuse ratings in
chapter 11.3.1 Protection.

Grounding Requirements
3.4.2
WARNING
GROUNDING HAZARD
For operator safety, it is important to 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.
Ground currents are higher than 3.5 mA.
•
Failure to ground the frequency converter properly could
result in death or serious injury.
3.4.2.1
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 generates a leakage current
in the ground 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 ground current. The ground 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.
Grounding must be reinforced in one of the following
ways:
See EN 60364-5-54 § 543.7 for further information.
proper ground connections.
Do not ground one frequency converter to
•
another in a daisy-chain fashion.
Keep the ground wire connections as short as

cover before mounting the mains power cable.
NOTICE
The EMC metal cover is only included in units with an
RFI filter.
Illustration 3.53 Mounting of EMC Shield.
3.5.2
Using Screened Control 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).
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 on the basis of
the following factors:
The conductibility of the screen material.
•
The contact resistance between the individual
•
screen conductors.
The screen coverage, i.e. the physical area of the
•
cable covered by the screen - often stated as a
percentage value.
Screen type, i.e. braided or twisted pattern.
•
33
3.5 Control Wiring Connection
Isolate control wiring from high power
•
components in the frequency converter.
If the frequency converter is connected to a
•
thermistor for PELV isolation, optional thermistor
control wiring must be reinforced/double
insulated. A 24 V DC supply voltage is
recommended.
Access

Cables
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 ground potential between
the frequency converter and the PLC is different, electric
noise may occur that disturbs the entire system. Solve this
problem by fitting an equalizing cable next to the control
cable. Minimum cable cross section: 16 mm2.

See chapter 6 Programming for details on
accessing parameters and programming.
Illustration 3.62 Location of Terminals 53 and 54 Switches and
Bus Termination Switch
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 1 network segment.
Repeaters divide network segments. Each repeater
functions as a node within the segment it is installed in.
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.
Always follow good common installation practice.
•
Low-impedance ground connection of the screen at every
node is important, including at high frequencies.
Connect a large surface of the screen to ground,
•
for example with a cable clamp or a conductive
cable gland. It may be necessary to apply

HIGH VOLTAGE
If input and output connections have been connected improperly, there is potential for high voltage on these terminals.
If power leads for multiple motors are improperly run in same conduit, there is potential for leakage current to charge
capacitors within the frequency converter, even when disconnected from mains input.
For initial start-up, make no assumptions about power components.
•
Follow pre-start procedures.
•
Failure to follow pre-start procedures could result in personal injury or damage to equipment.
1.Switch off the Input power to the unit and ensure that it is locked out. Do not rely on the frequency converter
disconnect switches for input power isolation.
2.Verify that there is no voltage on input terminals L1 (91), L2 (92), and L3 (93), phase-to-phase and phase-toground,
3.Verify that there is no voltage on output terminals 96 (U), 97 (V), and 98 (W), phase-to-phase and phase-to-ground.
4.Confirm continuity of the motor by measuring ohm values on U-V (96-97), V-W (97-98), and W-U (98-96).
5.Check for proper grounding of the frequency converter as well as the motor.
6.Inspect the frequency converter for loose connections on terminals.
7.Record the following motor-nameplate data
7aPower
7bVoltage
7cFrequency

Danfoss has a software program available for developing,
storing, and transferring frequency converter
programming. The MCT 10 Set-up Software allows the user
to connect a PC to the frequency converter and perform
live programming rather than using the LCP. Additionally,
all frequency converter programming can be done off-line
and simply downloaded to the frequency converter. Or the
entire frequency converter profile can be loaded onto the
PC for back-up storage or analysis.
The USB connector or RS-485 terminal are available for
connecting the PC to the frequency converter.
When the frequency converter is in Status mode, status

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.
9.2 Warning and Alarm Types
9.2.1 Warnings
A warning is issued when an alarm condition is impending,
or when an abnormal operating condition is present and
may result in the frequency converter issuing an alarm. A
warning clears itself when the abnormal condition is
removed.
Alarm Trip
9.2.2
An alarm is issued when the frequency converter is
tripped, that is, the frequency converter suspends
operation to prevent frequency converter or system
damage. The motor coasts to a stop. The frequency
converter logic continues to operate and monitor the
frequency converter status. After the fault condition is
corrected, the frequency converter can be reset. It is then
ready to start operation again.
