Abstract

In a method and device for controlling several stepping motor modules in printing or copying machines, sets of ramp data are centrally calculated in a computer in a calculation phase and are transmitted via a bus system to one logic unit each in a loading phase. The ramp data are stored in the stepping motor modules in non-volatile memories and are loaded to corresponding main memories depending on operating conditions. When a stepping motor module is operational, the current set of ramp data is transmitted by a control unit. A start signal transmitted by the control unit initiates the conversion of the set of ramp data selected in the corresponding logic unit into impulses of variable distance.
