* : When position control of movement amount 0 is executed, the BUSY signal also
turns ON. However, since the ON time is short, the ON status may not be detected in
the sequence program.
Master module)
 When the remote station READY (RX(n+7)B) turns from OFF to ON, the
parameter setting range is checked, and if there is no error, D75P2
READY complete turns OFF.
When the remote station READY (RX(n+7)B) turns OFF, D75P2 READY
turns ON.
 This is used for the interlock with the sequence program, etc.
 When the positioning start (RY(n+1)0, RY(n+1)1) turns ON, and the
D75P2 starts the positioning process, start complete turns ON.
(The start complete signal also turns ON during zero point return control.)
 Turning OFF Positioning start also turns OFF Start complete.
Positioning start (RY(n+1)0)
(RY(n+1)1)
Start complete (RXn1)
(RXn2)
 This signal turns ON at the start of positioning, zero point return or JOG,
and turns OFF after the " Da.8 Dwell time" has passed after positioning
stop. (This signal remains ON during positioning.) This signal turns OFF
when stopped with step operation.
 During manual pulse generator operation, this signal turns ON while the
"Manual pulse generator enable flag (RX(n+2)9, RX(n+4)9)" is ON.
 This signal turns OFF at an error complete or stop.
 This signal turns ON for the time set in parameter "Positioning complete
signal output time" from the time that each positioning data No. positioning
control is completed. (This does not turn ON when parameter "Positioning
complete signal output time" is 0.)
 If positioning is started (including zero point return), JOG operation or
manual pulse generator operation start is executed while this signal is ON,
the signal will turn OFF.
 This signal will not turn ON when speed control or positioning is canceled
midway.
 This signal turns ON when an error listed and turns OFF when the error is
reset.
 In the WITH mode, this signal turns ON when the positioning data is
started, and in the AFTER mode, this signal turns ON when the positioning
data positioning is completed.
 This signal turns OFF with the M code OFF request on the rising edge of
(RY(n+2)6, RY(n+4)6).
 When there is no M code designated (when " Da.9 M code" is 0), this
signal will remain OFF.
With using continuous path control for the positioning operation, the
positioning will continue even when this signal does not turn OFF.
However, a warning will occur. (Warning code: 503)
 When the Remote station READY signal (RX(n+7)B) turns OFF, the M
code ON signal will also turn OFF.
 If operation is started while the M code is ON, an error will occur. (Error
code: 536)
 Since the speed changed by speed change or positioning operation speed
override has exceeded the speed limit value, this signal turns ON during
operation at the speed limit value.
 This signal turns OFF when the speed decreases to within the speed limit
value or the axis stops. (*
 This signal turns ON during speed change processing.
This signal turns OFF at start of deceleration by the stop signal during
speed change processing or after completion of speed change processing.
