Output voltage at base frequency can be adjusted separately, such as 80 to 240V (230V series) or 320 to 480V
(460V series).
Output voltage at max. frequency can be adjusted separately, such as 80 to 240V (230V series) or 320 to 480V
(460V series).
Torque boost Auto: Optimum control corresponding to the load torque.
