Abstract

PURPOSE: To ignore the disturbance due to the delay time of transmission, by sample-holding the output of the position deviation counter by the sample pulse having a much longer period than the delay time of transmission of the photocoupler or the D/A converter.
CONSTITUTION: The position deviation counter 11 obtaines the deviation signal by counting the difference between the command pulse and the feedback pulse delivered from the position detector 17, and then applies this deviation signal to sample holding circuit 12. The circuit 12 carries out the sample holding with the sample pulse having a much longer period than the delay time of transmission of the photocoupler 13 or the D/A converter 14. The position deviation which is sample- held once at the circuit 12 is applied to the converter 14 via coupler 13. The converter 14 converts the applied position deviation into the analog signal and then applies this analog signal to the actuator 16. Thus the actuator 16 is operated so that the position deviation may be 0.
