Abstract
A control device for electric direct drives of a transfer system contains at least one monitoring device which, in the case of the malfunctioning of a direct drive, switches the control device into an emergency operating mode. In the emergency operating mode, the control device disconnects the linear drive affected by the malfunction from power and controls the remaining direct drives preferably at full power or at a slightly higher power. Thereby, a freedom from collision is established between the forming tool and the transfer device, after which the press is preferably stopped.
