*２） The MEND output is OFF at Servo OFF.
*３） The PCSTART1 input is ignored when MEND output is OFF.
*４） This is enabled at the User I/O setting Option 1.
The Point No. output method depends on the [Point No. Output Method (No644.0)] setting at the time
of PCSTART1 input.
*５） Any changes made to the point table setting during a motion will not be applied to the motion.
*６） The startup timing depends on other conditions.
