Test Mode Transition/Cancellation - Mitsubishi Electric MELSEC iQ-R16MTCPU Programming Manual

Test mode transition/cancellation

At a test mode transition request, initial processing is performed, and parameters and programs are read. Refer to initial
processing for details of initial processing. (Page 71 Initial processing)
Test mode transition
When transitioning to test mode all axes become servo OFF regardless of the servo ON/OFF status. ("[Rq.1123] All axes
servo ON command (R: M30042/Q: M2042)" and "[Rq.1155] Servo OFF command (R: M34495+32n/Q: M3215+20n)" turn
ON.)
In the following cases, transition to test mode is not possible.
• "[Rq.1120] PLC ready flag (R: M30000/Q: M2000)" turns ON.
• There is an axis in operation.
• An error occurred in the initial processing at test mode request transition.
Note that at transition to test mode, all servo ON axes will change to servo OFF.
Test mode cancellation
To cancel test mode, request cancellation after stopping all axes. If there is an axis in operation, test mode cannot be
cancelled. When test mode is cancelled the servo ON/OFF status of all axes ("[Rq.1123] All axes servo ON command (R:
M30042/Q: M2042)", "[Rq.1155] Servo OFF command (R: M34495+32n/Q: M3215+20n)") does not change from that of
before cancellation.
To servo ON the servo OFF axes after test mode is cancelled, turn "[Rq.1155] Servo OFF command (R: M34495+32n/Q:
M3215+20n)" from ON to OFF.
