Remedy
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)
