7.4.5 Fault codes

The fault codes, their causes and correcting actions are presented in the table below. The shadowed
faults are A faults only. The items written in white on black background present faults for which you
can program different responses in the application. See parameter group Protections.
Note! When you contact the factory or the distributor due to a fault, it is advisable to write down all
fault texts and codes that appear on the keypad

Possible cause
Frequency converter has detected too high a
current (>4*I ) in the motor cable:
n
sudden heavy load increase
−
short circuit in motor cables
−
unsuitable motor
−
The DC-link voltage has exceeded the limits
defined in Table 4-3.
too short a deceleration time
−
high overvoltage spikes in supply
−
Current measurement has detected that the
sum of motor phase current is not zero.
insulation failure in cables or motor
−
component failure
-
faulty operation
-
DC-link voltage is under the voltage limits
defined in Table 4-3.
most probable cause: too low a supply
−
voltage
frequency converter internal fault
−
Current measurement has detected that there
is no current in one motor phase.
Heatsink temperature is under –10 ° C
Heatsink temperature is over 90 ° C.
Overtemperature warning is issued when the
heatsink temperature exceeds 85 ° C.
Motor stall protection has tripped.
Motor overheating has been detected by
frequency converter motor temperature
model. Motor is overloaded.

Correcting measures
Check loading.
Check motor size.
Check cables.
Make the deceleration time longer.
Check motor cables and motor.
Reset the fault and restart.
Should the fault re-occur, contact
the distributor near to you.
In case of temporary supply voltage
break reset the fault and restart the
frequency converter. Check the
supply voltage. If it is adequate, an
internal failure has occurred.
Contact the distributor near to you.
Check motor cable and motor.
Check the correct amount and flow
of cooling air.
Check the heatsink for dust.
Check the ambient temperature
(p2.6.8).
Make sure that the switching
frequency is not too high in relation
to ambient temperature and motor
load.
Check motor.
Check that Pump or Fan is not
jammed
Decrease the motor load.
If no motor overload exists, check
the temperature model parameters.
