Product Overview
An adjustable frequency drive is an electronic motor
controller that converts AC line power input into a variable
AC waveform output. The frequency and voltage of the
output are regulated to control the motor speed or torque.
The adjustable frequency drive can vary the speed of the
motor in response to system feedback, such as position
sensors on a conveyor belt. The adjustable frequency drive
can also regulate the motor by responding to remote
commands from external controllers.
In addition, the adjustable frequency drive 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.

2.4.1 Requirements
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 be performed only by
trained and qualified personnel. Failure to follow these
guidelines could result in death or serious injury.
Input fusing is required to provide this
protection, see Figure 2.6. If not factory supplied,
fuses must be provided by the installer as part of
installation. See maximum fuse ratings in
10.3 Fuse Specifications.
2
2
CAUTION
WIRING ISOLATION!
Run input power, motor wiring and control wiring in three
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 adjustable frequency drive and associated
equipment performance.
For your safety, comply with the following requirements.
Electronic controls equipment is connected to
•
hazardous AC line voltage. Extreme care should
be taken to protect against electrical hazards
when applying power to the unit.
Run motor cables from multiple adjustable
•
frequency drives separately. Induced voltage from
output motor cables run together can charge
equipment capacitors even with the equipment
turned off and locked out.
Overload and Equipment Protection
An electronically activated function within the
•
adjustable frequency drive 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
8 Warnings and Alarms for details on the trip
function.
Because the motor wiring carries high frequency
•
current, it is important that wiring for line power,
motor power, and control is run separately. Use
metallic conduit or separated shielded wire.
Failure to isolate power, motor, and control
wiring could result in less than optimum
equipment performance.
All adjustable frequency drives must be provided
•
with short-circuit and overcurrent protection.
Figure 2.6 Adjustable Frequency Drive Fuses
Wire Type and Ratings
All wiring must comply with local and national
•
regulations regarding cross-section and ambient
temperature requirements.
Danfoss recommends that all power connections
•
be made with a minimum 167 °F [75 °C] rated
copper wire.
See 10.1 Power-dependent Specifications for
•
recommended wire sizes.
Grounding Requirements
2.4.2
WARNING
GROUNDING HAZARD!
For operator safety, it is important to ground the
adjustable frequency drive properly in accordance with
national and local electrical codes, as well as instructions
contained within these instructions. Ground currents are
higher than 3.5 mA. Failure to ground the adjustable
frequency drive properly could result in death or serious
injury.
NOTE!
It is the responsibility of the user or certified electrical
installer to ensure correct grounding of the equipment in
accordance with national and local electrical codes and
standards.

requirements
2.4.2.1
Follow national and local codes regarding protective
grounding of equipment with a leakage current > 3.5 mA.
Adjustable frequency drive technology implies high
frequency switching at high power. This will generate a
leakage current in the ground connection. A fault current
in the adjustable frequency drive 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, shielded
motor cables, and adjustable frequency drive power.
EN/IEC61800-5-1 (Power Drive System Product Standard)
requires special care if the leakage current exceeds 3.5 mA.

2.4.5.4 Using Shielded Control Cables
Correct shielding
The preferred method in most cases is to secure control
and serial communication cables with shielding clamps
provided at both ends to ensure best possible high
frequency cable contact.
If the ground potential between the adjustable frequency
drive and the PLC is different, electrical 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: 0.025 in2 [16 mm2].

Control Terminal Functions
Adjustable frequency drive functions are commanded by
receiving control input signals.
Each terminal must be programmed for the
•
function it will be supporting in the parameters
associated with that terminal. See Table 2.5 for
terminals and associated parameters.
It is important to confirm that the control
•
terminal is programmed for the correct function.
See 4 User Interface for details on accessing
parameters and 5 About Adjustable FrequencyDrive Programming for details on programming.
The default terminal programming is intended to
•
initiate adjustable frequency drive functioning in
a typical operational mode.
2.4.5.6
Jumper Terminals 12 and 27
A jumper wire may be required between terminal 12 (or
13) and terminal 27 for the adjustable frequency drive to
operate when using factory default programming values.
Digital input terminal 27 is designed to receive an
•
24 V DC external interlock command. In many
applications, the user wires an external interlock
device to terminal 27
When no interlock device is used, wire a jumper
•
between control terminal 12 (recommended) or
13 to terminal 27. This provides an internal 24 V
signal on terminal 27.

If the adjustable frequency drive is in alarm mode or in an
overvoltage situation, the mechanical brake immediately
cuts in.
In the vertical movement, the key point is that the load
must be held, stopped, controlled (raised, lowered) in a
perfectly safe mode during the entire operation. Because
the adjustable frequency drive is not a safety device, the
crane/lift designer (OEM) must decide on the type and
number of safety devices (e.g. speed switch, emergency
brakes, etc.) to be used, in order to be able to stop the
load in case of emergency or malfunction of the system,
according to relevant national crane/lift regulations.

Stop functionality and safety levels are appropriate and
sufficient. Safe Stop is designed and approved suitable for
the requirements of:
-Safety Category 3 according to EN ISO 13849-1
-Performance Level "d" according to EN ISO
13849-1:2008
-SIL 2 Capability according to IEC 61508 and EN

Refer to EN IEC 61800-5-2 for details of Safe torque off
(STO) function.
2)
Refer to EN IEC 60204-1 for details of stop category 0
and 1.
Activation and Termination of Safe Stop
The Safe Stop (STO) function is activated by removing the
voltage at Terminal 37 of the Safe Inverter. By connecting
the Safe Inverter to external safety devices providing a safe
delay, an installation for a safe Stop Category 1 can be
obtained. The Safe Stop function can be used for
asynchronous, synchronous, and permanent magnet
motors.
WARNING
After installation of Safe Stop (STO), a commissioning test
as specified in 2.5.2 Safe Stop Commissioning Test must be
performed. A passed commissioning test is mandatory
after first installation and after each change to the safety
installation.
Safe Stop Technical Data
The following values are associated to the different types
of safety levels:

installation in a closed cabinet that is only accessible for
skilled personnel.
SISTEMA Data
Functional safety data is available via a data library for use
with the SISTEMA calculation tool from the IFA (Institute
for Occupational Safety and Health of the German Social
Accident Insurance) and data for manual calculation. The
library is complete and continually extended.
Terminal 37 Safe Stop Function
2.5.1
The adjustable frequency drive is available with safe stop
functionality via control terminal 37. Safe stop disables the
control voltage of the power semiconductors of the
adjustable frequency drive output stage. This in turn
prevents generating the voltage required to rotate the
motor. When the Safe Stop (T37) is activated, the
adjustable frequency drive issues an alarm, trips the unit,
and coasts the motor to a stop. Manual restart is required.
The safe stop function can be used as an emergency stop
for the adjustable frequency drive. In normal operating
mode when safe stop is not required, use the regular stop
function instead. When automatic restart is used, ensure
the requirements of ISO 12100-2 paragraph 5.3.2.5 are
fulfilled.
Liability Conditions
It is the responsibility of the user to ensure that qualified
personnel installs and operates the safe stop function:
Read and understand the safety regulations
•
concerning health and safety/accident prevention

The information and instructions of the instruction manual
are not sufficient for a proper and safe use of the safe stop
functionality. The related information and instructions of
the relevant Design Guide must be followed.
Protective Measures
Qualified and skilled personnel are required for
•
installation and commissioning of safety
engineering systems
The unit must be installed in an IP54 cabinet or
•
in an equivalent environment. In special
applications, a higher IP degree is required
The cable between terminal 37 and the external
•
safety device must be short circuit protected
according to ISO 13849-2 table D.4
When external forces influence the motor axis (for
•
example, suspended loads), additional measures
are required (for example, a safety holding brake)
to eliminate potential hazards
Safe Stop Installation and Set-up
It is not recommended to stop the adjustable
•
frequency drive by using the Safe Torque Off
function. If a running adjustable frequency drive
is stopped by using the function, the unit trips
and stops by coasting. If unacceptable or
dangerous, use another stopping mode to stop
the adjustable frequency drive and machinery,
before using this function. Depending on the
application, a mechanical brake can be required.
For synchronous and permanent magnet motor
•
adjustable frequency drives, in a multiple IGBT
power semiconductor failure: In spite of the
activation of the Safe Torque Off function, the
system can produce an alignment torque which
maximally rotates the motor shaft by 180/p
degrees. p denotes the pole pair number.
This function is suitable for performing
•
mechanical work on the system or affected area
of a machine only. It does not provide electrical
safety. Do not use this function as a control for
starting and/or stopping the adjustable frequency
drive.
Follow these steps to perform a safe installation of the
adjustable frequency drive:
1.Remove the jumper wire between control
terminals 37 and 12 or 13. Cutting or breaking
the jumper is not sufficient to avoid shortcircuiting. (See jumper on Figure 2.21.)
2.Connect an external Safety monitoring relay via a
NO safety function to terminal 37 (safe stop) and
either terminal 12 or 13 (24 V DC). Follow the
instructions for the safety device. The Safety
monitoring relay must comply with Category
3 /PL “d” (ISO 13849-1) or SIL 2 (EN 62061).
WARNING
SAFE STOP FUNCTION!
The safe stop function does NOT isolate AC line voltage to
the adjustable frequency drive or auxiliary circuits. Perform
work on electrical parts of the adjustable frequency drive
or the motor only after isolating the AC line voltage supply
and waiting the length of time specified in Table 1.1.
Failure to isolate the AC line voltage supply from the unit
and waiting the time specified could result in death or
serious injury.

WARNING
Safe Stop activation (that is removal of 24 V DC voltage
supply to terminal 37) does not provide electrical safety.
The Safe Stop function itself is therefore not sufficient to
implement the Emergency-Off function as defined by EN
60204-1. Emergency-Off requires measures of electrical
isolation, for example, by switching off line power via an
additional contactor.
1.Activate the Safe Stop function by removing the
24 V DC voltage supply to the terminal 37.
2.After activation of Safe Stop (that is, after the
response time), the adjustable frequency drive
coasts (stops creating a rotational field in the
motor). The response time is typically less than 10
ms.
The adjustable frequency drive is guaranteed not to restart
creation of a rotational field by an internal fault (in
accordance with Cat. 3 PL d acc. EN ISO 13849-1 and SIL 2
acc. EN 62061). After activation of Safe Stop, the display
shows the text ”Safe Stop activated”. The associated help
text says, "Safe Stop has been activated”. This means that
the Safe Stop has been activated, or that normal operation
has not been resumed yet after Safe Stop activation.

Safe Stop Commissioning Test
After installation and before first operation, perform a
commissioning test of the installation using safe stop. Also,
perform the test after each modification of the installation.
NOTE!
The requirements of Cat. 3 /PL “d” (ISO 13849-1) are only
fulfilled while 24 V DC supply to terminal 37 is kept
removed or low by a safety device which itself fulfills Cat.
3 PL “d” (ISO 13849-1). If external forces act on the motor,
it must not operate without additional measures for fall
protection. External forces can arise for example, in the
event of vertical axis (suspended loads) where an
unwanted movement, for example caused by gravity, could
cause a hazard. Fall protection measures can be additional
mechanical brakes.
By default the Safe Stop function is set to an Unintended
Restart Prevention behavior. Therefore, to resume
operation after activation of Safe Stop,
1.reapply 24 V DC voltage to terminal 37 (text Safe

WARNING
Automatic Restart Behavior is permitted in one of the two
situations:
1.Unintended restart prevention is implemented by
other parts of the safe stop installation.
2.A presence in the hazard zone can be physically
excluded when safe stop is not activated. In
particular, paragraph 5.3.2.5 of ISO 12100-2 2003
must be observed
2.5.2 Safe Stop Commissioning Test
After installation and before first operation, perform a
commissioning test of an installation or application, using
Safe Stop.
Perform the test again after each modification of the
installation or application involving the Safe Stop.
NOTE!
A passed commissioning test is mandatory after first installation and after each change to the safety installation.
The commissioning test (select one of cases 1 or 2 as
applicable):
Case 1: Restart prevention for Safe Stop is required (that is
Safe Stop only where 5-19 Terminal 37 Safe Stop is set to
default value [1], or combined Safe Stop and MCB 112
where 5-19 Terminal 37 Safe Stop is set to [6] PTC 1 & RelayA or [9] PTC 1 & Relay W/A):
1.1 Remove the 24 V DC voltage supply to
terminal 37 using the interrupt device while the
adjustable frequency drive drives the motor (that
is line power supply is not interrupted). The test
step is passed when
the motor reacts with a coast, and
•
the mechanical brake is activated (if
•
connected)
the alarm “Safe Stop [A68]” is displayed
•
in the LCP, if mounted
1.2 Send Reset signal (via bus, digital I/O, or
[Reset] key). The test step is passed if the motor
remains in the safe stop state, and the
mechanical brake (if connected) remains
activated.
1.3 Reapply 24 V DC to terminal 37. The test step
is passed if the motor remains in the coasted
state, and the mechanical brake (if connected)
remains activated.
1.4 Send Reset signal (via bus, digital I/O, or
[Reset] key). The test step is passed when the
motor becomes operational again.
The commissioning test is passed if all four test steps 1.1,
1.2, 1.3 and 1.4 are passed.
Case 2: Automatic Restart of Safe Stop is wanted and

2.2 Reapply 24 V DC to terminal 37.
The test step is passed if the motor becomes operational
again. The commissioning test is passed if both test steps
2.1 and 2.2 are passed.
NOTE!
See warning on the restart behavior in 2.5.1 Terminal 37
Safe Stop Function
WARNING
The Safe Stop function can be used for asynchronous,
synchronous and permanent magnet motors. Two faults
can occur in the power semiconductor of the adjustable
frequency drive. When using synchronous or permanent
magnet motors a residual rotation can result from the
faults. The rotation can be calculated to Angle = 360/
(Number of Poles). The application using synchronous or
permanent magnet motors must take this residual rotation
into consideration and ensure that it does not pose a
safety risk. This situation is not relevant for asynchronous
motors.

3.1 Pre-start
3.1.1 Safety Inspection
WARNING
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 adjustable
frequency drive, even when disconnected from line power
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.Input power to the unit must be OFF and locked
out. Do not rely on the adjustable frequency
drive 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-to-ground,
3.Verify that there is no voltage on output
terminals 96 (U), 97 (V), and 98 (W), phase-tophase 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 adjustable
frequency drive as well as the motor.
6.Inspect the adjustable frequency drive for loose
connections on terminals.
7.Record the following motor nameplate data:
power, voltage, frequency, full load current, and
nominal speed. These values are needed to
program motor nameplate data later.

WARNING
HIGH VOLTAGE!
Adjustable frequency drives contain high voltage when
connected to AC line power. 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 adjustable frequency drive is connected to AC
line power, the motor may start at any time. The
adjustable frequency drive, motor, and any driven
equipment must be in operational readiness. Failure to be
in operational readiness when the adjustable frequency
drive is connected to AC line power could result in death,
serious injury, equipment, or property damage.
1.Confirm input voltage is balanced within 3%. If
not, correct input voltage imbalance before
proceeding. Repeat procedure after voltage
correction.
2.Ensure optional equipment wiring, if present,
matches installation application.
3.Ensure that all operator devices are in the OFF
position. Panel doors closed or cover mounted.
4.Apply power to the unit. DO NOT start the
adjustable frequency drive at this time. For units
with a disconnect switch, turn to the ON position

If the status line at the bottom of the LCP reads AUTO
REMOTE COAST, this indicates that the unit is ready to
operate but is missing an input signal on terminal 27.
3.3 Basic Operational Programming
Programming
For best performance, adjustable frequency drives require
basic operational programming before running. Basic
operational programming requires entering motor
nameplate data for the motor being operated and the
minimum and maximum motor speeds. The recommended
parameter settings are intended for start-up and checkout
purposes. Application settings may vary. See 4.1 LocalControl Panel for detailed instructions on entering data
through the LCP.
Enter data with power ON, but before operating the
adjustable frequency drive. There are two ways of
programming the adjustable frequency drive: either by
using the Smart Application Set-up (SAS) or by using the
procedure described further down. The SAS is a quick
wizard for setting up the most commonly used
applications. At first power-up and after a reset, the SAS
appears on the LCP. Follow the instructions that appear on
the successive screens for setting up the applications
listed. SAS can also be found under the Quick Menu. [Info]
can be used throughout the Smart Set-up to see help
information for various selections, settings and messages.
NOTE!
The start conditions will be ignored while in the wizard.
NOTE!
If no action is taken after first power-up or reset, the SAS
screen will automatically disappear after 10 minutes.
When not using the SAS, enter data in accordance with
the following procedure.
1.Press [Main Menu] twice on the LCP.
2.Press the navigation keys to scroll to parameter
group Q2 Quick Set-up and press [OK].

Automatic Motor Adaptation
Automatic motor adaptation (AMA) is a test procedure that
measures the electrical characteristics of the motor to
optimize compatibility between the adjustable frequency
drive and the motor.
The adjustable frequency drive builds a
•
mathematical model of the motor for regulating
output motor current. The procedure also tests
the input phase balance of electrical power. It
compares the motor characteristics with the data
entered in parameters 1-20 Motor Power [kW] to
1-25 Motor Nominal Speed.

This parameter gives stator winding
resistance (Rs) similar to asynchronous
motor stator resistance. When line-line
data (where stator resistance is
measured between any two lines) are
available, you need to divide it with 2.
This parameter gives direct axis
inductance of the PM motor. When lineline data are available, you need to
divide it with 2.
This parameter gives back EMF across
stator terminal of PM Motor at 1,000
RPM mechanical speed specifically. It is
defined between line to line and
expressed in RMS Value. In case the PM
Motor specifications provides this value
related to another motor speed, the
voltage must be recalculated for 1,000

5.1 Introduction
The adjustable frequency drive is programmed for its
application functions using parameters. Parameters are
accessed by pressing either [Quick Menu] or [Main Menu]
on the LCP. (See 4 User Interface for details on using the
LCP function keys.) Parameters may also be accessed
through a PC using the MCT 10 Set-up Software (see
5.6.1 Remote Programming with MCT 10 Set-up Software).
adjustable frequency drive reference to 0 Hz.
(This sets the minimum adjustable frequency
drive speed at 0 Hz.)

The quick menu is intended for initial start-up (Q2-** QuickSet-up). Data entered in a parameter can change the
options available in the parameters following that entry.
The main menu accesses all parameters and allows for
advanced adjustable frequency drive applications.
5.2 Programming Example
Here is an example for programming the adjustable
frequency drive for a common application in open-loop
using the quick menu.
This procedure programs the adjustable
•
frequency drive to receive a 0–10 V DC analog
control signal on input terminal 53
The adjustable frequency drive will respond by
•
providing 6-60 Hz output to the motor proportional to the input signal (0–10 V DC = 6–60 Hz)
Select the following parameters using the navigation keys
to scroll to the titles and press [OK] after each action.

5.6 Remote Programming with MCT 10 Setup Software
Danfoss has a software program available for developing,
storing, and transferring adjustable frequency drive
programming. The MCT 10 Set-up Software allows the user
to connect a PC to the adjustable frequency drive and
perform live programming rather than using the LCP.
Additionally, all adjustable frequency drive programming
can be done off-line and simply downloaded to the
adjustable frequency drive. Or the entire adjustable
frequency drive profile can be loaded onto the PC for
backup storage or analysis.
The USB connector or RS-485 terminal is available for
connecting to the adjustable frequency drive.
MCT 10 Set-up Software is available for free download at
www.VLT-software.com. A CD is also available by
requesting part number 130B1000. For further information,
see the Instruction Manual.

7.1 Status Display
When the adjustable frequency drive is in status mode,
status messages are generated automatically from within
the adjustable frequency drive and appear in the bottom
line of the display (see Figure 7.1.)
Figure 7.1 Status Display
a.The first part of the status line indicates where
the stop/start command originates.
b.The second part of the status line indicates where
the speed control originates.
c.The last part of the status line gives the present
adjustable frequency drive status. These show the
operational mode the adjustable frequency drive
is in.
NOTE!
In auto/remote mode, the adjustable frequency drive
requires external commands to execute functions.
7.2 Status Message Definitions Table
Table 7.1, Table 7.2 and Table 7.3 define the meaning of the
status message display words.
OffThe adjustable frequency drive does not react
to any control signal until [Auto On] or [Hand
On] is pressed.
Auto onThe adjustable frequency drive is controlled
from the control terminals and/or the serial
communication.
Hand onThe adjustable frequency drive can be
controlled by the navigation keys on the LCP.
Stop commands, reset, reversing, DC brake,
and other signals applied to the control
terminals can override local control.
Table 7.1 Operation Mode
RemoteThe speed reference is given from external
signals, serial communication, or internal
preset references.

8.1 System Monitoring
The adjustable frequency drive 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
adjustable frequency drive itself. In many cases, it indicates
failure conditions from input voltage, motor load or
temperature, external signals, or other areas monitored by
the adjustable frequency drive’s internal logic. Be sure to
investigate those areas exterior to the adjustable frequency
drive as indicated in the alarm or warning.
8.2 Warning and Alarm Types
Warnings
A warning is issued when an alarm condition is impending
or when an abnormal operating condition is present and
may result in the adjustable frequency drive issuing an
alarm. A warning clears by itself when the abnormal
condition is removed.
Alarms
Trip
An alarm is issued when the adjustable frequency drive is
tripped, that is, the adjustable frequency drive suspends
operation to prevent adjustable frequency drive or system
damage. The motor will coast to a stop. The adjustable
frequency drive logic will continue to operate and monitor
the adjustable frequency drive status. After the fault
condition is remedied, the adjustable frequency drive can
be reset. It will then be ready to start operation again.
A trip can be reset in any of four ways
Press [Reset] on the LCP

An alarm that causes the adjustable frequency drive to
trip-lock requires that input power is cycled. The motor will
coast to a stop. The adjustable frequency drive logic will
continue to operate and monitor the adjustable frequency
drive status. Remove input power to the adjustable
frequency drive and correct the cause of the fault, then
restore power. This action puts the adjustable frequency
drive into a trip condition as described above and may be
reset in any of those four ways.

8.4 Warning and Alarm Definitions
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,
88
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 adjustable frequency drive
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
adjustable frequency drive.
WARNING/ALARM 4, Mains phase loss
A phase is missing on the supply side, or the line voltage
imbalance is too high. This message also appears for a
fault in the input rectifier on the adjustable frequency
drive. Options are programmed at 14-12 Function at MainsImbalance.
Troubleshooting
Check the supply voltage and supply currents to the
adjustable frequency drive.
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
adjustable frequency drive 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
adjustable frequency drive voltage rating. The unit is still
active.
WARNING/ALARM 7, DC overvoltage
If the intermediate circuit voltage exceeds the limit, the
adjustable frequency drive trips after a time.
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
If the alarm/warning occurs during a power sag,
the solution is to use kinetic backup (14-10 LineFailure)
WARNING/ALARM 8, DC undervoltage
If the intermediate circuit voltage (DC link) drops below
the undervoltage limit, the adjustable frequency drive
checks if a 24 V DC backup supply is connected. If no 24 V
DC backup supply is connected, the adjustable frequency
drive trips after a fixed time delay. The time delay varies
with unit size.
Troubleshooting
Make sure that the supply voltage matches the
adjustable frequency drive voltage.
Perform input voltage test.
Perform soft charge circuit test.
WARNING/ALARM 9, Inverter overload
The adjustable frequency drive is about to cut out because
of an overload (current too high for too long). The counter
for electronic, thermal inverter protection issues a warning
at 98% and trips at 100%, while giving an alarm. The
adjustable frequency drive cannot be reset until the
counter is below 90%.
The fault is that the adjustable frequency drive has run
with more than 100% overload for too long.

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. Make sure that the
system can operate safely at a higher torque.
Check the application for excessive current draw
on the motor.
WARNING/ALARM 13, Overcurrent
The inverter peak current limit (approximately 200% of the
rated current) is exceeded. The warning lasts about 1.5 s,
then the adjustable frequency drive trips and issues an
alarm. This fault can be caused by shock loading or quick
acceleration with high inertia loads. It can also appear after
kinetic backup if the acceleration during ramp-up is quick.
If extended mechanical brake control is selected, trip can
be reset externally.
Troubleshooting
Remove power and check if the motor shaft can
be turned.
Make sure that the motor size matches the
adjustable frequency drive.
Check parameters 1-20 to 1-25 for correct motor
data.
ALARM 14, Ground fault

WARNING 25, Brake resistor short-circuit
The brake resistor is monitored during operation. If a short
circuit occurs, the brake function is disabled and the
warning appears. The adjustable frequency drive is still
operational but without the brake function. Remove power
to the adjustable frequency drive and replace the brake
resistor (see 2-15 Brake Check).
WARNING/ALARM 26, Brake resistor power limit
The power transmitted to the brake resistor is calculated as
a mean value over the last 120 s of run time. The
calculation is based on the intermediate circuit voltage and
the brake resistance value set in 2-16 AC Brake Max.Current. The warning is active when the dissipated braking
is higher than 90% of the brake resistance power. If [2] Trip
is selected in 2-13 Brake Power Monitoring, the adjustable
frequency drive will trip when the dissipated braking
energy reaches 100%.
WARNING
There is a risk of substantial power being transmitted to
the brake resistor if the brake transistor is short-circuited.
WARNING/ALARM 27, Brake chopper fault
The brake transistor is monitored during operation and if a
short circuit occurs, the brake function is disabled and a
warning is issued. The adjustable frequency drive is still
operational but, since the brake transistor has shortcircuited, substantial power is transmitted to the brake
resistor, even if it is inactive.
Remove power to the adjustable frequency drive and
remove the brake resistor.
This alarm/warning could also occur should the brake
resistor overheat. Terminals 104 and 106 are available as
brake resistors Klixon inputs, see section Brake ResistorTemperature Switch in the Design Guide.

10.3 Fuse Specifications
10.3.1 Fuses
It is recommended to use fuses and/or circuit breakers on
the supply side as protection in case of component breakdown inside the adjustable frequency drive (first fault).
NOTE!
This is mandatory in order to ensure compliance with IEC
60364 for CE or NEC 2009 for UL.
WARNING
Personnel and property must be protected against the
consequence of component breakdown internally in the
adjustable frequency drive.
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 protected against short-circuit
and overcurrent according to national/international
regulations.
NOTE!
The recommendations given do not cover branch circuit
protection for UL.
Short-circuit protection
Danfoss recommends using the fuses/circuit breakers
mentioned below to protect service personnel and
property in case of component breakdown in the
adjustable frequency drive.
10.3.2
Recommendations
WARNING
In case of malfunction, not following the recommendation
may result in risk to personnel and damage to the
adjustable frequency drive and other equipment.
The following tables list the recommended rated current.
Recommended fuses are of the type gG for small to
medium power sizes. For larger powers, aR fuses are
recommended. For circuit breakers, Moeller types have
been tested to have a recommendation. Other types of
circuit breakers may be used provided they limit the
energy into the adjustable frequency drive to a level equal
to or lower than the Moeller types.
If fuses/circuit breakers according to recommendations are
chosen, possible damage to the adjustable frequency drive
will mainly be limited to damage inside the unit.
For further information, please see Application Note Fusesand Circuit Breakers.
10.3.3
Fuses or circuit breakers are mandatory to comply with IEC
60364. Danfoss recommend using a selection of the
following.
The fuses below are suitable for use on a circuit capable of
delivering 100,000 Arms (symmetrical), 240 V, 480 V, 500 V,
600 V, or 690 V depending on the adjustable frequency
drive voltage rating. With the proper fusing the adjustable
frequency drive short circuit current rating (SCCR) is
100,000 Arms.
