3.4.2 Details of input signals
(1) WDT error, H/W error signal (X10)
This signal turns on when a watchdog timer error is detected through the self-diagnostic function of the QD73A1.
In this case, Servo ON signal (SVON) turns off and analog output becomes 0.
(2) QD73A1 READY signal (X11)
When PLC READY signal (Y2D) is turned on through a sequence program, fixed parameters are checked and
this signal turns on.
When PLC READY signal (Y2D) is turned off, this signal turns off.
Use this signal as an interlock in sequence programs.
(3) OPR request signal (X12)
This signal turns on at any of the following timing.
When the power is turned on
When the CPU module was reset
When OPR starts
When Servo READY signal (READY) turns off while BUSY signal (X14) is on
When Servo READY signal (READY) turns off while BUSY signal (X14) is off
(only when "0: Clear the deviation counter when the servo ready signal is OFF." is selected for "Deviation
counter clear setting" in the switch setting)
This signal turns off when OPR is completed.
When PLC READY signal (Y2D) is turned on (rising edge), this signal does not turn on.
(4) OPR complete signal (X13)
This signal turns on when OPR is completed.
This signal does not turn on if operation stopped during OPR.
This signal turns off when JOG operation or major positioning control is started.
In the count method, this signal turns off when OPR starts.
This signal turns off when Servo READY signal (READY) turns off (only when "0: Clear the deviation counter
when the servo ready signal is OFF." is selected for "Deviation counter clear setting" in the switch setting)
(5) BUSY signal (X14)
This signal turns on when major positioning control, JOG operation, or OPR starts.
This signal turns off when command pulse output is completed.
If positioning is started while BUSY signal (X14) is on, the error "BUSY signal ON at start" (error code: 81) occurs.
