PREF: 21.03 Default: 0.00 % Range: 0.00 to 25.00 %
This parameter allows for no-load stator resistance voltage drop compensation. This correctly fluxes the motor (under no-load
conditions) at low output frequencies, thereby increasing available motor torque. Fixed boost can be set in addition to auto
boost and acceleration boost.
