ON : Not
ready/WDT
error
•
When the PLC READY signal [Y1D] turns from OFF to ON, the parameter setting
range is checked, and if there is no error, this signal turns OFF.
•
When the PLC READY signal [Y1D] turns OFF, this signal turns ON.
•
When a WDT error occurs, this signal turns ON.
•
This is used for the interlock with the sequence program, etc.

When the positioning start signal turns ON, and the AD75 starts the positioning
process, this signal turns ON.

•
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 " 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.
(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.

when the error is reset.

setting
ON : M code set
•
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)
Important
*1 When position control of movement amount 0 is executed, the BUSY signal also turns ON. However,
since the ON time is short, the ON status may not be detected in the sequence program.
*2 AD75 positioning complete refers to when the output of position/speed commands from AD75 is
completed.
Thus, even if the AD75 positioning complete signal turns ON, the system may continue to operate.
