Troubleshooting and fault elimination
Cause
Ambient temperature is too high
Heatsink is very dirty
Impermissible high currents or
frequent and too long
acceleration processes
Motor too hot due to
impermissible high currents or
frequent and too long
acceleration processes
No PTC connected
Controller is too hot inside
Motor too hot due to
impermissible high currents or
frequent and too long
acceleration processes
No PTC connected
Mains voltage is too high
Braking operation
Earth leakage at motor end

Fault elimination
Fault messages
Remedy
Allow controller to cool and provide
for better ventilation
Clean heatsink
l Check drive dimensioning
l Check load, replace
rough−running, defective
bearings, if necessary
Check drive dimensioning
Connect PTC or switch off monitoring
l Reduce controller load
l Improve cooling
l Check fan in the controller
Check drive dimensioning
Connect PTC or switch off monitoring
Check supply voltage
l Increase deceleration times
l For operation with an external
brake resistor:
– Check dimensioning,
connection and supply cable of
the brake resistor
– Increase deceleration times
Check motor supply cable and motor
for earth fault (disconnect motor
from the inverter)
