FIELD: controlling.
SUBSTANCE: invention relates to the field of automation and computing technology, and can be used to automate the control of displacement mechanisms in units equipped with stepper electric drives. The technical result of the claimed technical solution is achieved by including interrelated logic elements "AND", "OR", dividers by 2, a clock frequency generator, a reset pulse shaper, pulse counters, a code comparison circuit, triggers, a displacement sensor, and a shift register.
EFFECT: ensured fault-free operation of the apparatus.
