More Information
Summary:The circuit has an end stage (5) for electrical connection to the stepper motor (1), a step generator (6) and at least one first control lead (7) for connecting the control unit to the step generator. The circuit has an arrangement (9-14) for setting the first control lead(s) to a defined potential on detecting the presence of a fault in the stepper motor, enabling the control unit to detect the presence of the potential.
