Abstract

PURPOSE: To detect overrun of a moving object and step-out of a servo motor by counting rough pulses, which are generated once each time the moving object moves by a prescribed quantity larger than the set unit movement quantity of a distribution pulse, to detect the movement quantity of the moving object.
CONSTITUTION: Movement quantity counter MVC is so controlled that this counter may be counted up each time moving object 10 moves by a prescribed quantity larger than the unit movement quantity set in 24 by a distribution pulse. The final count value after the completion of pulse distribution of counter MVC in 24 is operated in 23 on a basis of the command movement quantity, which is instructed by numerical control data, before pulse distribution in 24, and an abnormal signal is transmitted if the count value of counter MVC exceeds the final count value in the course of pulse distribution in 24 and if deviation between the calculation value of counter MVC and the final calculation value exceeds a prescribed value after the completion of pulse distribution in 24. Thus, overrun of moving object 10 and step- out of servo motor 12 dependent upon the throuble of circuit 24 and servo motor driving part 13 can be detected.
