■Command in-position flag
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.)
■Home position return request flag
This signal comes ON when the power is switched ON, when the absolute system has not been set, when the machine home
position return has not been executed at the absolute position system, when a machine home position return operation starts.
This signal goes OFF when a machine home position return operation completes.
(For details of home position return request flag, refer to Page 31 Outline of Home Position Return Control.)
■Home position return complete flag
This signal comes ON when a machine home position return operation completes normally. This signal goes OFF when the
operation start.
■Position-speed switching latch flag
This signal is used during the position-speed switching control for interlocking the command speed change function. During
the position-speed switching control, this signal comes ON when speed control takes over. This signal goes OFF when the
next positioning data is processed, and during JOG operation or manual pulse generator operation.
■Axis warning detection flag
This signal comes On when an axis warning is reported and goes OFF when the axis error reset signal comes ON.
■Speed change 0 flag
This signal comes ON when the speed is "0" by the speed change or override. Otherwise, it goes OFF.
■M code ON
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 the "[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: 0992H) 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: 19A0H) will occur.
■Error detection
This signal turns ON when an error (Page 591 List of Error Codes), and turns OFF when the error is reset on "[Cd.5] Axis
error reset".
■Start complete
This signal turns ON when the positioning start signal turns ON and the Simple Motion module starts the positioning process.
(The start complete signal also turns ON during home position return control.)
