P 3.2.2 Brake Chopper Voltage Reduce
Description: Set the activation level of the brake chopper. If set to 0, the brake chopper is active if the voltage exceeds the overvoltage
control activation level. The value set is subtracted from the overvoltage control activation level, lowering the brake chopper activation
level, respectively.
Default Value: 0
Unit: V
