Remedy
Check voltage supply
Prolong deceleration times.
l
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)
It is absolutely necessary to repeat the data
