Motor control device for variable revs drive in printing machine, uses microprocessor with incorporated memory holding control characteristic and/or control characteristic correction values

摘要

The motor control device has a required value source (1) mounted on a printed circuit (12) provided with a microprocessor (4), coupled to the required value source terminals via circuit board conductor paths. The microprocessor incorporates a memory (3') holding a motor control characteristic and/or correction values for a motor characteristic, used for providing a pulse width modulated signal for the drive motor. An Independent claim for a printing machine with at least one ventilator motor is also included.
