Fault detection and elimination
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, for
instance, because of
l impermissible continuous current
l frequent or too long acceleration
processes
Ambient temperature too high
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

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