Automatic Retract Function Used For The Home Position Return - Mitsubishi Electric MELSERVO-J4 Instruction Manual

5. HOW TO USE THE PROGRAM

5.4.13 Automatic retract function used for the home position return

If the current position is on or beyond the proximity dog at the time of dog type/count type home position
return, it is not necessary to start after performing JOG operation, etc. to move the machine backward.
When the current position is on the proximity dog, the machine moves backward automatically, and the
home position return is performed.
At start-up, the operation is performed in the direction of home position return. When the servo amplifier
detects the limit switch, 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 the limit switch on the opposite side, and [AL. 90 Home position
return incomplete warning] will occur.
The software limit cannot be used with these functions.
