The judgement of the positioning start completion and positioning completion is made
with the following signals.
• Positioning start completion .........M2400+20n (positioning start complete signal)
• Positioning completion ...............M2401+20n (positioning complete signal)
(1) A program that outputs the M-code from PY000 to PY00F to external destination
after conversion into BCD code at the positioning start completion is shown below.
