This device used for matrix printing devices, counting automations, in robotics, etc. It avoids current rushes and unpleasant sound effects, as well as reduces the braking distance, with a minimum number of additional elements. The device consists of an angular speed pick-up (1), a mono vibrator (2), a real-speed bloc (3), a set-speed bloc (4), a differential amplifier (5), a trigger (6), an end step (7), a servomotor (8), an "AND-NO" logical element (9), a microprocessor control bloc (10) and an analogous key (11).
