Abstract
A circuit arrangement is provided for the continual operation monitoring and error diagnosis of a stepper motor controllable at its windings by control logic and driver stages using stepping pulses which are phase-shifted relative to each other. A multi-stage ring counter is used for logically representing the desired values of the stepping pulses with the ring counter under control of the stepping control pulses applied to the input of the control logic stage. A multi-stage compare circuit arrangement is used to compare the logical values of the stepping pulses from the ring counter with the logical values of the output signals from both the control logic stage and driver stage.
