To stop the positioning operation, be sure to insert the stop contact before the positioning instruction
so that the 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.
