Remedy
Check drive selection
l
Check setting of C0120
l
Allow controller to cool and ensure better
ventilation
Clean heat sink
Check drive selection
l
Check load, if necessary, replace
l
defective bearings
Check drive selection
Connect PTC or switch off monitoring
l Reduce controller load
l Improve cooling
l Check fan in the controller
Check drive selection
Connect PTC or switch off monitoring
Check voltage supply
l Prolong deceleration times.
l 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)
