Troubleshooting and fault elimination
Cause
•
Failure of one/several motor phase(s)
•
Motor current too low
Mains voltage too low
DC-bus voltage too low
400 V controller connected to 240 V mains
Short circuit
Excessive capacitive charging current of the motor
cable
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
2
x t overload) Motor is thermally overloaded, for instance,
because of
•
impermissible continuous current
•
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
Mains voltage too high
Braking operation
Earth leakage on the motor side

Remedy
Connect motor
•
Check motor cables
•
Check V boost
min
•
Connect motor to corresponding power or adapt the
motor under C0599.
Check mains voltage
Check supply module
Connect controller to the appropriate mains voltage
•
Find reason for short circuit; check motor cable
•
Check braking resistor and cable for braking resistor
Use shorter motor cables with lower charging current
Check motor, check motor cable
Use shorter motor cables with lower charging current
Deactivate earth-fault detection for testing purposes
•
Increase acceleration time
•
Check drive selection
Check wiring
Check motor
•
Increase deceleration time
•
Check size of external brake resistor
Check drive selection
•
Check drive selection
•
Check setting of C0120
Allow controller to cool and ensure better ventilation
Clean heatsink
•
Check drive selection
•
Check load, if necessary, replace defective bearings
Check drive selection
Connect PTC or switch off monitoring
•
Reduce controller load
•
Improve cooling
•
Check fan in the controller
Check drive selection
Connect PTC or switch off monitoring
Check voltage supply
•
Prolong deceleration times.
•
Operation with external brake resistor:
– Check dimensioning, connection and cable of the
brake resistor.
– Increase the deceleration times
Check motor cable and motor for earth fault (disconnect
motor from inverter)
