Fan Curve 2-77
Fan Curve When torque performance is set to Fan Curve the relation ship between
frequency and voltage is as shown in the following figure. The fan curve
provides the option to generate voltage that is a function of the stator
frequency squared up to the motor nameplate frequency. Above base
frequency voltage is a linear function of frequency. At low speed the fan
curve is offset by the run boost parameter to provide necessary starting
torque. No extra parameters are needed for fan curve.
