Sizing

Drive sizing is based on the rated motor current and power. To achieve the rated
motor power, the rated current of the drive must be more than or equal to the rated
motor current. Also, the rated power of the drive must be more than or equal to the
rated motor power. The power ratings are the same regardless of the supply voltage
in one voltage range.
