PROBLEM TO BE SOLVED: To provide a servo-press machine where the cause of unstable driving can be removed before the driving or during the driving. SOLUTION: Disclosed is a servo-press machine determining whether or not a drive power supply voltage Vpn between a positive power supply path and a negative power supply path 120(P, N) that connect a power supply device 110 and a motor rotation control section 30(33) is lower than an induced voltage Vm of a servomotor 7, and correcting speed-related data based on slide motion information, so as to be a low speed when the servo-press machine has determined that the drive power supply voltage is lower than the induced voltage.
