Fault name Possible cause
Undervoltage (fault) The DC-link voltage is lower
than the limits.
Undervoltage (alarm)

NOTE!
This fault becomes active
only if the drive is in Run
state.
Input phase The input line phase is
missing.
Output phase super- The measurement of cur-
vision rent tells that there is no
current in 1 motor phase.
AC drive undertem- Too low a temperature in
perature (fault) the heatsink of the power
unit or in the power board.
AC drive undertem- The heatsink temperature is
perature (alarm) less than -10 °C.
AC drive overtemper- Too high a temperature in
ature (fault, heatsink) the heatsink of the power
unit or in the power board.
AC drive overtemper- The heatsink temperature is
ature (alarm, heat- more than 100 °C.
sink)
AC drive overtemper-
ature (fault, board)
AC drive overtemper-
ature (alarm, board)
Motor stalled The motor stalled.
Motor overtempera- There is too heavy a load on
ture the motor.
Motor underload There is not a sufficient load
on the motor.
How to correct the fault
If there is a temporary supply volt-
age break, reset the fault and
restart the drive.
Do a check of the supply voltage. If
too low a supply volt-
the supply voltage is sufficient,
age
there is an internal fault.
AC drive internal fault
Ask instructions from the distribu-
a defective input fuse
tor near to you.
the external charge
switch is not closed
Do a check of the supply voltage,
the fuses and supply cable.
Do a check of the motor cable and
the motor.
Do a check of the actual quantity
and flow of cooling air.
Examine the heatsink for dust.
Do a check of the ambient temper-
ature.
Make sure that the switching fre-
quency is not too high in relation to
the ambient temperature and the
motor load.
Do a check of the motor and the
load.
Decrease the motor load. If there is
no motor overload, do a check of
the temperature model parame-
ters.
Do a check of the load.
