ABSTRACT:
A method and apparatus for controlling a multiple motor drive arranged to drive printing cylinders of a printing machine sychronously decelerates each of the drives upon a failure or defect occurring in one or more of the components of the drive system such that the individual printing cylinders are decelerated in a manner synchronized with one another with respect to rotation angle. The apparatus includes a main control device which detects a failure in one of the drive system components and controls the drive units to decelerate the drive units to a standstill in accordance with a time function. The time function is determined by the rotation of the drive unit which contains the component that failed. The apparatus ensures in an electrical and single-fault manner that the failure of a component in one of the drive units does not lead to rotation of the cylinders or axles beyond a predetermined amount which would cause damage to the grippers or the cylinders by the grippers contacting the cylinder surface of an adjacent cylinder.
