Start with "[Cd.184] Positioning start signal"
This section describes operations started with "[Cd.184] Positioning start signal".
• When the "[Cd.184] Positioning start signal" is turned ON, the start complete signal ([Md.31] Status: b14) and "[Md.141]
BUSY signal" turn ON, and positioning operations start. The on state of the "[Md.141] BUSY signal" indicates that the
corresponding axis is in operation.
• When the "[Cd.184] Positioning start signal" is turned OFF, the start complete signal ([Md.31] Status: b14) turns OFF. If the
"[Cd.184] Positioning start signal" remains ON even after the positioning is completed, the start complete signal ([Md.31]
Status: b14) also remains ON.
• If the positioning start signal is turned ON again while the "[Md.141] BUSY signal" is ON, Start during operation (Warning
code: 0900H) occurs.
• The operation performed after the completion of the positioning operation depends on whether or not the next positioning
control is set.

The "[Md.141] BUSY signal" turns ON even when the position control of a movement amount 0 is
implemented. However, as the ON time is short, the ON status may not be detected by the program. (Start
complete signal ([Md.31] Status: b14), Positioning complete signal ([Md.31] Status: b15), and M code ON
signal ([Md.31] Status: b12) can detect the ON status using the program.)

7.1 Starting
Processing
• If [Da.9] Dwell time is set, the positioning module waits for the set time to elapse, and the positioning will
be completed.
• When positioning is finished, the "[Md.141] BUSY signal" turns OFF, and the start complete signal
([Md.31] Status: b14) turns ON. However, when the speed control has been used or the ON time of
Positioning complete signal is 0, Positioning complete signal [X14, X15, X16, X17] does not turn on.
• When the time set in "[Pr.40] Positioning complete output signal time" elapses, the positioning complete
signal ([Md.31] Status: b15) turns OFF.
• If [Da.9] Dwell time is set, the positioning module waits for the set time to elapse.
• When the time set in [Da.9] Dwell time elapses, the next positioning control starts.
