DC-bus overvoltage
If the braking energy is too high and the DC-bus voltage therefore exceeds the overvoltage

threshold which results from the mains setting in

C00173

, the "Overvoltage in the DC bus"

error message is output and the response set in

C00600

is activated (default setting:

"Trouble").

Note!

For hoist applications the "Fault" response should be selected in

C00600

(in

combination with an emergency stop via mechanical brakes).
