Chapter 6 Sequence Program Used for Positioning Control
POINT
The BUSY signal turns ON even when position control of movement amount 0 is
executed. However, since the ON time is short, the ON status may not be
detected in the sequence program.
(The ON status of the start complete signal, positioning complete signal and M
code ON signal can be detected in the sequence program.)
