Description
This parameter sets the rated nominal operating voltage for the motor insulation system in Vrms. For instance, if a motor rated for a 480 Vac supply is connected to the drive, then MOTOR.VOLTMAX should be set to 480.
This value also sets the regen resistor and over voltage thresholds in the drive to acceptable values for the motor so that the motor windings are not damaged. Since VOLTMAX is specified as nominal RMS Voltage, the drive will fault if the DC bus VBUS.VALUE exceeds 2x VOLTMAX which provides sufficient margin to be safe and to prevent false trips.
