Cause
Grounded motor phase
Excessive capacitive charging
current of the motor cable
Acceleration time too short
(C0012)
Defective motor cable
Interturn fault in the motor
Deceleration time set too short
(C0013)
Frequent and long overload
Motor is thermally overloaded,

x t overload) for instance, because of
l impermissible continuous
current
l frequent or too long
acceleration processes
Ambient temperature too high Allow controller to cool and ensure
Heatsink very dirty
Impermissibly high currents or
too frequent and too long
acceleration
Motor too hot because of
excessive currents or frequent
and too long accelerations
PTC not connected
Controller too hot inside
Motor too hot because of
excessive currents or frequent
and too long accelerations
PTC not connected

Remedy
Check motor, check motor cable
Use shorter motor cables with
lower charging current
Deactivate earth−fault detection for
testing purposes
l Increase acceleration time
Check drive selection
l
Check wiring
Check motor
Increase deceleration time
l
Check size of external brake
l
resistor
Check drive selection
l Check drive selection
l Check setting of C0120
better ventilation
Clean heatsink
Check drive selection
l
Check load, if necessary,
l
replace defective bearings
Check drive selection
Connect PTC or switch off
monitoring
Reduce controller load
l
l Improve cooling
Check fan in the controller
l
Check drive selection
Connect PTC or switch off
