Details
This signal that comes ON under the speed control can be used to judge whether the operation is performed under the speed
control or position control. The signal goes OFF when the power is switched ON, under the position control, and during JOG
operation or manual pulse generator operation. During the speed-position or position-speed switching control, this signal comes
ON only when the speed control is in effect. During the speed-position switching control, this signal goes OFF when the speed-
position switching signal executes a switching over from speed control to position control. During the position-speed switching
control, this signal comes ON when the position-speed switching signal executes a switching over from position control to speed
control.
This signal is used during the speed-position switching control for interlocking the movement amount change function. During the
speed-position switching control, this signal comes ON when position control takes over. This signal goes OFF when the next
positioning data is processed, and during JOG operation or manual pulse generator operation.
This signal is ON when the remaining distance is equal to or less than the command in-position range (set by a detailed
parameter). This signal remains OFF with data that specify the continuous path control (P11) as the operation pattern. The state
of this signal is monitored every operation cycle except when the monitoring is canceled under the speed control or while the
speed control is in effect during the speed-position or position-speed switching control. While operations are performed with
interpolation, this signal comes ON only in respect of the starting axis. (This signal goes OFF in respect of all axes upon starting.)
This signal comes ON when a home position return is required and goes OFF at completion of a home position return.
For details of home position return request flag, refer to Page 33 Outline of Home Position Return Control.
This signal comes ON when a machine home position return operation completes normally. This signal goes OFF when the
operation start.
This signal is used during the speed-position switching control for interlocking the movement amount change function. During the
speed-position switching control, this signal comes ON when position control takes over. This signal goes OFF when the next
positioning data is processed, and during JOG operation or manual pulse generator operation.
This signal comes ON when an axis warning is reported and goes OFF when the axis error reset signal comes ON.
This signal comes ON when the speed is "0" by the speed change or override. Otherwise, it goes OFF.
In the WITH mode, this signal turns ON when the positioning data operation is started. In the AFTER mode, this signal turns ON
when the positioning data operation is completed.
This signal turns OFF with "[Cd.7] M code OFF request".
When M code is not designated (when "[Da.10] M code/Condition data No./Number of LOOP to LEND repetitions/Number of
pitches" 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, the warning "M code ON signal ON" (warning code: 0D52H) will occur.
When the PLC READY signal [Y0] turns OFF, the M code ON signal will also turn OFF.
If operation is started while the M code is ON, the error "M code ON signal start" (error code: 1AA0H) will occur.
This signal turns ON when an error (Page 623 List of Error Codes), and turns OFF when the error is reset on "[Cd.5] Axis
error reset".
This signal turns ON when the positioning start signal turns ON and the Motion module starts the positioning process. (The start
complete signal also turns ON during home position return control.)
This signal turns ON for the time set in "[Pr.40] Positioning complete signal output time" from the instant when the positioning
control for each positioning data No. is completed.
For the interpolation control, the positioning complete signal of interpolation axis turns ON during the time set to the reference
axis.
(It does not turn ON when "[Pr.40] Positioning complete signal output time" is "0".)
If positioning (including home position return), JOG/Inching operation, or manual pulse generator operation is started while this
signal is ON, the signal will turn OFF.
This signal will not turn ON when speed control or positioning is canceled midway.
