Important
1 : The BUSY signal turns ON even when position control of movement amount 0 is
executed. However, since the ON time is short, the ON status may not be detected in the
sequence program.
2 : "Position control complete" of the QD70 refers to the point when the pulse output from
QD70 is completed.
Thus, even if the QD70's positioning complete signal turns ON, the system may continue
operation.

• When the Programmable controller READY signal [Y0] turns from OFF to ON, the
parameter and the OPR data setting range is checked. If no error is found, this signal
turns ON. (When the axis error occurrence signal [X1] is ON, this signal does not turn
ON if the Programmable controller READY signal [Y0] is turned from OFF to ON.)
• When the Programmable controller READY signal [Y0] turns OFF, this signal turns
OFF.
• When a watch dog timer (WDT) error occurs, this signal turns OFF.
• This signal is used for interlock in a sequence program, etc.
Programmable controller
READY signal [Y0]
Module READY signal [X0]
• This signal turns ON if an error occurs in any of axes 1 to 8, and turns OFF when
" Cd. 1 Axis error reset" is set for all axes.
(Use " Md. 10 Error status" to confirm the error status of the corresponding axis.)
• This signal turns ON if a warning occurs in any of axes 1 to 8, and turns OFF when
" Cd. 1 Axis error reset" is set for all axes.
(Use " Md. 11 Warning status" to confirm the warning status of the corresponding
axis.)
• This signal turns ON at the start of positioning control, OPR control or JOG operation.
It turns OFF when the " Da. 7 Dwell time" has passed after positioning control stops.
(This signal remains ON during positioning control.)
• This signal turns OFF at error or stop.
• This signal turns ON when the positioning start signal turns ON and the QD70 starts
the positioning control process.
(The start complete signal also turns ON during OPR control.)
Positioning start signal [Y8]
Start complete signal [X10]
• This signal turns ON for the time set in " Pr. 7 Positioning complete signal output
time" from completion of position control of the corresponding axis.
(It does not turn ON if 0 is set in " Pr. 7 Positioning complete signal output time".)
• While ON, this signal turns OFF if a positioning control start (including OPR control)
or JOG operation start is made.
• This signal does not turn ON at the termination of JOG operation.
• This signal does not turn ON if position control is stopped midway.
