8.3.3. Travel Limit Output (±): OTXA
Reports that the Motor gets in the area specified by the travel limits.
(For both cases of software and hardware over travel limits.)
Different from the outputs OTPA and OTMA, there is no function to distinguish the direction of
limit switch.

Put the Motor in servo-off state by
the input SVON.
Move the Motor out of the area, or turn off the
Motor servo and move the Motor manually
When a travel limit is detected in the middle of operation, the Motor stops before it reaches the
target position. Thus, the output IPOS (In-position) does not close.
When the travel limit is detected while the Motor is stopping, the output IPOS does not change
because the System maintains the position at where the last positioning was completed.
