• When the PLC READY signal [Y0] turns from OFF to ON, the parameter setting
range is checked. If no error is found, this signal turns ON.
• When the PLC READY signal [Y0] turns OFF, this signal turns OFF.
• When watch dog timer error occurs, this signal turns OFF.
• This signal is used for interlock in a sequence program, etc.

• After the PLC is turned ON or the CPU module is reset, this signal turns ON if the
access from the CPU module to the QD75 is possible.
• When "Asynchronous" is selected in the module synchronization setting of the CPU
module, this signal can be used as interlock for the access from a sequence program
to the QD75.

• In the WITH mode, this signal turns ON when the positioning data operation is
started. In the AFTER mode, this signal turns ON when the positioning data
operation is completed.
• This signal turns OFF with the "
Cd.7
M code OFF request".
• When M code is not designated (when
Da.10
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 [Y0] 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.

• This signal turns ON at the start of positioning, OPR or JOG operation. It turns OFF
when the "
Da.9
Dwell time" has passed after positioning stops. (This signal
remains ON during positioning.) This signal turns OFF when the positioning is
stopped with step operation.
• During manual pulse generator operation, this signal turns ON while the "
Cd.21
Manual pulse generator enable flag" is ON.
• This signal turns OFF at error completion or positioning stop.

• This signal turns ON when the positioning start signal turns ON and the QD75 starts
the positioning process.

• This signal turns ON for the time set in "
Pr.40
Positioning complete signal output
time" from the instant when the positioning control for each positioning data No. is
completed.
(It does not turn ON when "
Pr.40
Positioning complete signal output time" is "0".)
• If positioning (including OPR), JOG/Inching operation, or manual pulse generator
operation is started while this signal is ON, the signal will turn OFF.
• This signal will not turn ON when speed control or positioning is canceled midway.
