PCT No. PCT/JP84/00177 Sec. 371 Date Dec. 7, 1984 Sec. 102(e) Date Dec. 7, 1984 PCT Filed Apr. 7, 1984 PCT Pub. No. WO84/04006 PCT Pub. Date Oct. 11, 1984.In a servo control circuit for driving a servomotor at a commanded velocity and torque, there are provided a servomotor voltage supply circuit, a servomotor drive current sensing circuit, a servomotor rotation sensor, a single counter for counting rotation sensor pulses, a processor for effecting current loop control based on an applied torque command input, as well as voltage output control of the voltage supply circuit, and a main processor for producing the torque command as an output. A pulse count value during a period T1 for current loop control is accumulated and the result is utilized by the main processor as position information over for a period T2. This allows a counter for position information input to be deleted, thereby providing advantages in terms of construction and economy. The invention is applicable to the control of all types of DC and AC servomotors.
