This signal turns ON at the start of positioning, zero point return or JOG, and turns
OFF after the "
Da.8
Dwell time" has passed after positioning stop. (This signal
remains ON during positioning.) This signal turns OFF when stopped with step
operation.
•
During manual pulse generator operation, this signal turns ON while the "

This signal turns ON for the time set in "

Positioning complete signal output
time" from the time that each positioning data No. positioning control is completed.
(This does not turn ON when "
Pr.41
Positioning complete signal output time" is 0.)
•
If positioning is started (including zero point return), JOG operation or manual pulse
generator operation start is executed while this signal is ON, the signal will turn OFF.
•
This signal will not turn ON when speed control or positioning is canceled midway.
•
After the BUSY signal [X4,X5,X6] turns OFF, the positioning complete signal
[X7,X8,X9] turns ON.

•
In the WITH mode, this signal turns ON when the positioning data is started, and in
the AFTER mode, this signal turns ON when the positioning data positioning is
completed.
•
This signal turns OFF with the "
Cd.14
M code OFF request".
•
When there is no M code designated (when "
Da.9
M code" is 0), this signal will
remain OFF.
•
With using continuous path control for the positioning operation, the positioning will
continue even when this signal does not turn OFF. However, a warning will occur.
(Warning code: 503)
•
When the PLC READY signal [Y1D] turns OFF, the M code ON signal will also turn
OFF.
•
If operation is started while the M code is ON, an error will occur. (Error code: 536)
