FIELD: mechanical engineering. SUBSTANCE: invention relates to the field of mechanical engineering. The device for counting the movements of the working body of the machine with a drive screw contains a screw rotation drive, a nut covering the screw and connected to the working body of the machine, and a rotary absolute encoder, the input of which is connected to the screw. The device is also equipped with a programming unit for screw pitch errors, a unit for calculating screw angle errors, the input of which is connected to a programming unit for pitch errors, a programmable code converter, the programming input of which is connected to the output of the angle error calculation unit, and the working input is connected to the output of the encoder, and a two–input adder, the first input of which is connected to the output of the code converter, and the second input is connected to the output of the encoder. EFFECT: increase in the accuracy of counting the movements of the working body of the machine with a drive screw is provided. 1 cl, 1 dwg.
