Start by the positioning start signal
The operation at starting by the positioning start signal is shown below.
• When the positioning start signal turns ON, the start complete signal ([Md.31] Status: b14) and BUSY signal turn ON, and
the positioning operation starts. It can be seen that the axis is operating when the BUSY signal is ON.
• When the positioning start signal turns OFF, the start complete signal ([Md.31] Status: b14) also turns OFF. If the
positioning start signal is ON even after positioning is completed, the start complete signal ([Md.31] Status: b14) will remain
ON.
• If the positioning start signal turns ON again while the BUSY signal is ON, the warning "Start during operation" (warning
code: 0D00H)" will occur.
• The process executed when the positioning operation is completed will differ by whether the next positioning control is
executed.

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 program. (The ON status of the start complete
signal ([Md.31] Status: b14), positioning complete signal ([Md.31] Status: b15) and M code ON signal ([Md.31]
Status: b12) can be detected in the program.)

Processing details
• If dwell time is set, the system will wait for the set time to pass, and then positioning will be completed.
• When positioning is completed, the BUSY signal will turn OFF and the positioning complete signal
([Md.31] Status: b15) will turn ON. However, when using speed control or when the positioning complete
signal ON time is "0", the signal will not turn ON.
• When the time set in "[Pr.40] Positioning complete signal output time" is passed, the positioning complete
signal ([Md.31] Status: b15) will turn OFF.
• If dwell time is set, the system will wait for the set time to pass.
• When the set dwell time is passed, the next positioning will start.
