16.7.13 Automatic retract function used for the home position return
For a home position return using the proximity dog, when the home position return is started from the
position on or beyond the proximity dog, the home position return is performed after the machine moves
back to the position where the home position can be performed.
(1) When the current position is on the proximity dog
When the current position is on the proximity dog, the machine moves backward automatically, and the
home position return is performed.
(2) When the current position is beyond the proximity dog
At start-up, the operation is performed in the direction of the home position return. When LSP (Forward
rotation stroke end) or LSN (Reverse rotation stroke end) is detected, the machine moves backward
automatically. The machine passes and stops before the proximity dog, and the home position return is
performed from the position again. If the proximity dog cannot be detected, the machine stops at LSP or
LSN on the opposite side, and [AL. 90 Home position return incomplete warning] will occur.
The software limit cannot be used with these functions.
