Abstract
Safety system for a printing machine having at least one machine drive, a brake device and an electronic control system therefor. The electronic control system has power control stages which permit electronic braking of the drive assembly, and a monitoring circuit, to which can be fed nominal and actual values of the speed of the drive assembly, and which actuate the brake device in the case of impermissibly high deviation between a nominal value and an actual value. Accelerations and decelerations necessary in the operation of the printing machine are achieved by suitable control of the respective machine drive.
