Abstract
A process supplies energy to electronically controlled drives, particularly drives for workpiece handling devices, in and on a press having a press slide. The workpiece handling devices are electromechanically driven and electronically controlled. In the event of a power supply system outage, at least the workpiece handling devices are supplied at least for a short time by an intermediate circuit of a drive amplifier or an uninterruptable power supply system with voltage. Thereby, all devices important for the movement of the workpiece handling devices are supplied with voltage from the intermediate circuit or the uninterruptable power supply system.
