1 STARTING AND STOPPING
1.1 Starting
Starting with Positioning start signal [Y10, Y11, Y12, Y13]
This section describes operations started with Positioning start signal [Y10, Y11, Y12, Y13].
• When Positioning start signal [Y10, Y11, Y12, Y13] is turned on, Start complete signal [X10, X11, X12, X13] and BUSY
signal [XC, XD, XE, XF] turn on, and the positioning operation starts. The on state of BUSY signal [XC, XD, XE, XF]
indicates that the corresponding axis is in operation.
• When Positioning start signal [Y10, Y11, Y12, Y13] is turned off, Start complete signal [X10, X11, X12, X13] turns off. If
Positioning start signal [Y10, Y11, Y12, Y13] remains on even after the positioning is completed, Start complete signal [X10,
X11, X12, X13] also remains on.
• If Positioning start signal is turned on again while BUSY signal [XC, XD, XE, XF] is on, Start during operation (Warning
code: 0900H) occurs.
• The operation performed after the completion of the positioning operation depends on whether or not the next positioning
control is set.

Time chart for starting
Even when the positioning control of a movement amount 0 is performed, BUSY signal [XC, XD, XE, XF] turns
on. However, since the ON time of the signal is short, the ON state of the signal may not be detected in the
program. (The on state of Start complete signal [X10, X11, X12, X13], Positioning complete signal [X14, X15,
X16, X17], and M code ON signal [X4, X5, X6, X7] can be detected in the program.)
Presence or absence of the next
positioning control
Processing
When the next positioning control is performed
• If [Da.9] Dwell time is set, the RD75 waits for the set time to elapse, and the positioning will be completed.
• When the positioning has been completed, BUSY signal [XC, XD, XE, XF] turns off and Positioning
complete signal [X14, X15, X16, X17] turns on. However, when the speed control has been used or the
ON time of Positioning complete signal is 0, Positioning complete signal [X14, X15, X16, X17] does not
turn on.
• When the time set in [Pr.40] Positioning complete signal output time elapses, Positioning complete signal
[X14, X15, X16, X17] turns off.
When the next positioning control is not
performed
• If [Da.9] Dwell time is set, the RD75 waits for the set time to elapse.
• When the time set in [Da.9] Dwell time elapses, the next positioning control starts.
