(6) Positioning complete signal (X15)
This signal turns on when major positioning control is completed (completion of command pulse output).
This signal turns off when the next positioning (major positioning control, OPR, or JOG operation) starts.
If major positioning control was cancelled during its operation, this signal does not turn on.
For the operation in case of cancellation of major positioning control, refer to the following.
Page 230, Section 12.1
(7) In-position signal (X16)
This signal turns on while the accumulated pulse amount in the deviation counter is within the set range of
" In-position range" (1 to
Pr.8
This signal turns off when positioning starts.

(X16)
Accumulated pulse amount are checked being compared with "
• When the power is turned on
• When automatic deceleration starts in positioning, and thereafter
• When a JOG start signal was turned off and deceleration starts in JOG operation, and thereafter
• When the near-point dog turned on and deceleration to the creep speed starts in OPR, and thereafter
(8) Excessive error signal (X17)
This signal turns on when accumulated pulse amount exceeds the accumulated pulse setting range.
In this case, the QD73A1's status is as follows.
• Analog output voltage: 0V
• Accumulated pulse: Reset to 0
• Servo ON signal (SVON): OFF
• Actual current value =

When PLC READY signal (Y2D) is turned on, this signal turns off.

Even if this signal turns on, Error detection signal (X18) does not turn on.
For the accumulated pulse setting range, refer to the following.
