2 COMMON PARAMETERS
2.4 Motion CPU Operating Status
"[Rq.1120] PLC ready flag (R: M30000/Q: M2000)" OFF -> ON (STOP -> RUN) processing
■Processing details
1. The Y device content is initialized based on the "Output mode setting of STOP to RUN" (Refer to Page 55 CPU
parameter) operation.
2. All parameters are read from a file. (Refer to Page 71 Initial processing)
3. Clear the M-code storage area of all axes.
4. The "PCPU READY complete flag (SM500)" is turned ON when all of the above steps are complete. (Motion SFC
program execution is possible. The execution of automatically started Motion SFC programs is started from the
beginning.)
• If there is a starting axis, an error occurs, and the processing above is not executed.
• The processing above is not executed during the test mode. It is executed when the test mode is cancelled and "[Rq.1120]
PLC ready flag (R: M30000/Q: M2000)" is ON.
Refer to the following for details on the processing time when the "[Rq.1120] PLC ready flag (R: M30000/Q:
M2000)" turns from OFF to ON.

"[Rq.1120] PLC ready flag (R: M30000/Q: M2000)" ON -> OFF (RUN -> STOP) processing
■Processing details
1. Deceleration stop of the starting axis.
2. Execution of the Motion SFC program is stopped. (The program currently being executed stops at the position where
only the set number of consecutive transitions has been executed.)
3. All Y devices are turned OFF. If the "Output mode setting of STOP to RUN" (Refer to Page 55 CPU parameter) is
"output the output (Y) status before STOP", the status prior to clearing is saved. However, the high-speed counter
module Y device set for the synchronous encoder or manual pulse generator input does not turn OFF even if the status
is STOP.
4. The "PCPU READY complete flag (SM500)" is turned OFF.
• Refer to the following for details on the processing time when the "[Rq.1120] PLC ready flag (R: M30000/Q:
M2000)" turns from ON to OFF.

• Axis stoppage processing when transitioning from the RUN status to STOP status may differ depending on
the cause of the stoppage. Refer to the following for details.
