An upper die can be mounted on the slide. A lower die can be placed on the bolster. The power storage unit is configured to be able to supply stored power to the servomotor. The current detector detects current supplied from the power storage unit. The control unit performs stop control to stop supply of current from the power storage unit to the servomotor based on a detection value of the current detector.
