PLC CPU)

The ON/OFF timing and conditions of the input signals are shown below.
• When the PLC READY signal [Y0] turns from OFF to ON, the parameter and the
ON: Prepared
OFF: Not OPR data setting range is checked. If no error is found, this signal turns ON. (When
prepared
the axis error occurrence signal [X1] is ON, this signal does not turn ON if the PLC
watch dog READY signal [Y0] is turned from OFF to ON.)
• When the PLC READY signal [Y0] turns OFF, this signal turns OFF.
timer error
• When a watch dog timer (WDT) error occurs, this signal turns OFF.
• This signal is used for interlock in a sequence program, etc.
Module READY signal [X0]
• This signal turns ON if an error occurs in any of axes 1 to 8, and turns OFF when
OFF: No error
ON: Error " Cd. 1 Axis error reset" is set for all axes.
occurrence
(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
OFF: No warning
ON: Warning " Cd. 1 Axis error reset" is set for all axes.
occurrence
(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.
OFF: Not BUSY
ON: BUSY 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
OFF: Start
incomplete
the positioning control process.
ON: Start
(The start complete signal also turns ON during OPR control.)
complete
Positioning start signal [Y8]
Start complete signal [X10]
• This signal turns ON for the time set in " Pr. 7 Positioning complete signal output
OFF: Positioning
incomplete
time" from completion of position control of the corresponding axis.
ON: Positioning
(It does not turn ON if 0 is set in " Pr. 7 Positioning complete signal output time".)
complete
• 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.
(Refer to
• This signal does not turn ON if position control is stopped midway.
