Abstract: A microprocessor-assisted sewing machine control equipment is flexibly applicable for controlling the sewing machine driving motor and further electric motors which are controlled independently of or in dependence on the rotary position. To this end, a control system is allocated to each electric motor, comprising an open-loop control unit for rotary-position-independent controlling, a closed-loop control unit for controlling the electric motor in dependence on the rotary position, and a selection unit. The selection unit couples for control either the closed-loop control unit or the open-loop control unit with the electric motor, depending on whether the electric motor is controlled by closed-loop control in dependence on the rotary position or by open-loop control independently of the rotary position.

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.
