ABSTRACT:
A reversible mechanical assembly is remote-controlled in displacements and in efforts by means of a device comprising a motion detector which delivers a pulse each time a driving shaft associated with a motor rotates by one step, the sign of the pulses being dependent on the direction of rotation of the motor. One input of a summing device is driven by the pulses delivered by the detector and the other input is driven by pulses delivered by an assembly for controlling the motor. The output signal of the summing device is fed back into the control assembly so as to constitute an effort return and also fed to the input of an amplifying circuit for controlling the torque produced by the motor.
