Abstract
A circuit configuration for the control of a servomotor (M) with the aid of current pulses supplied by a current-controlled final stage (1) of a control system. The pattern of current rise is analyzed after actuation of the final stage (1) for identifying a short circuit in the servomotor (M) across the power supply system (+U.sub.B). An excessively high current (I.sub.K), after a measuring period (T.sub.M), commencing after the transistor (LT) of the final stage (1) has been placed in saturated state, is indicative of a short circuit.
