Fault Cause
400 V controller is connected
to 240 V mains
Short circuit Short circuit
Capacitive charging current of
the motor cable too high
Earth fault A motor phase has earth
contact
Capacitive charging current of
the motor cable too high
Controller Acceleration time set is too
overload during short (C0012)
acceleration or
Defective motor cable
short circuit
Interturn fault in the motor
Controller Deceleration time set is too
overload during short (C0013)
deceleration
Controller Frequent and too long
overload during overload
steady-state
operation
Motor overload Motor is thermally overload by

Remedy
Connect controller to correct
mains voltage
Search for cause of short
circuit; check motor cable
Check brake resistor and cable
to brake resistor
Use shorter/low-capacitance
motor cable
Check motor; check motor cable
Use shorter/low-capacitance
motor cable
Deactivate earth-fault detection
for inspection purposes
Increase acceleration time
Check drive dimensioning
Check wiring
Check motor
Increase deceleration time
Check dimensioning of the
external brake resistor
Check drive dimensioning
Check drive dimensioning
Check setting of C0120
Allow controller to cool and
provide better ventilation
Clean heatsink
Check drive dimensioning
Check load, exchange
rough-running, defective
bearings if necessary
Check drive dimensioning
