* AD75 positioning complete refers to when the output of pulses from AD75 is completed.
Thus, even if the AD75 positioning complete signal turns ON, the system may continue to
operate.

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 " Cd.22
Manual pulse generator enable flag" is ON.
• This signal turns OFF at an error complete or stop.
• This signal turns ON for the time set in " Pr.41 Positioning complete signal output

time" from the time that each positioning data No. positioning control is completed.
ON : Positioning
(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.
OFF : No error
• This signal turns ON when an error listed in section 14.1 occurs, and turns OFF
ON : Error
when the error is reset.

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)
