5.4.13 Automatic retract function used for the home position return
For a home position return using a proximity dog, if the home position return starts from or beyond the
proximity dog, this function executes the home position return after the position is shifted back to where the
home position return is possible.
(1) When the current position is on the proximity dog
When the current position is on the proximity dog, the position is shifted back automatically to execute
the home position return.

After the position shifts to the position

0 r/min
(2) When the current position is beyond the proximity dog
The position is shifted in a direction of the home position return. When LSP (Forward rotation stroke
end) or LSN (Reverse rotation stroke end) is detected, the position is shifted back automatically. The
position will be shifted passing the proximity dog, and the travel will stop. The home position return will
be restarted from that position. If the proximity dog is not detected, the travel stops at LSP or LSN on the
opposite side, and [AL. 90 Home position return incomplete warning] occurs.
