Abstract
A servo-press machine determining whether or not a drive power supply voltage between a positive power supply path and a negative power supply path that connect a power supply device and a motor rotation control section is lower than an induced voltage of a servomotor, and correcting speed-related data based on slide motion information when the servo-press machine has determined that the drive power supply voltage is lower than the induced voltage.
