via HMI:
Description:
This parameter is important for the precise operation of the VVW control. The imprecise setting will cause the

Adjustable 200 to 600 V
Range:
Properties: cfg
Access groups MOTOR, STARTUP
via HMI:
Description:
Set according to the data on the motor nameplate and the wire connection on the motor terminal box. This
