regulated rather than terminal voltage. The default value of 100.0 % provides full compensation. This parameter can be adjusted to apply less
compensation if required or not. If this parameter is adjusted then the set point for the field weakening voltage loop (Pr 5.59 ) may need adjusting also
to get the required armature voltage on the motor.
default value of 100 % provides full compensation. In some motors compensation windings are employed to correct for speed droop under load and
so 100 % compensation is not required. In these cases this parameter must be adjusted to apply the correct amount of compensation. Setting a
negative value will cause the speed to fall as load increases.
