Abstract
The present invention pertains to the register coordination of cylinders of a web-fed rotary printing press which print on a web, wherein a first cylinder printing on one side of the web is driven by a first motor and a second cylinder printing on the same side of the web is driven by a second motor. An angular position of the second cylinder is coordinated with the first cylinder in good register by a controller. In the case of a change in a production condition, at least one controller parameter (kP, kD, kI, kf) of the controller is changed and the controller setting is adapted to the production condition as a result.
