To stop the positioning operation, be sure to insert the stop contact before the positioning instruction so that STL
instruction cannot be turned off (reset) until the "pulse output monitor" flag (M8340 (for Y000)) is turned off.
To prevent simultaneous activation of positioning instructions, the instruction activation timing should be delayed by 1
scan time.
