11.3.4 Positioning Stop Factor
(1) Stop factor and how to deal with stop factor
• If following factor occurs during positioning, it stops without completing positioning.
In case positioning stops by stop instruction (STP, EMG) or following stop factor, generally, the only axis
where stop instruction is executed or stop factor occurs stops.

Note
*1 : Positioning refers to position control, speed control by positioning data.
*2 : If axis is „Output prohibited status‟ after being stopped, run a instruction to cancel „Output
prohibited status‟. (CLR instruction) .
*3 : Stop by sequence program refers to stop by “Stop instruction” at XGB program.
(2) Stop Process and Priority
(a) Dec. stop process
• If it stops due to deceleration stop instruction, since positioning operation is not complete, it does not
generate positioning completion signal.
(b) Process of emergency stop and external input upper/lower limits
• If emergency stop instruction or external input upper/lower limits are inputted during positioning control,
it stops positioning control and turns into „Output prohibited stats‟, generating an error.
(c) Stop process priority
The priority of stop process is as follows.
Dec. stop < Emg. stop
