[Pr.43] Home position return method
Set the "home position return method" for carrying out machine home position return.
Setting value Details
0: Near-point dog After decelerating at the near-point dog ON, stop at the zero signal and complete the machine home
method position return.
4: Count method 1 After decelerating at the near-point dog ON, move the designated distance, and complete the
machine home position return with the zero signal.
5: Count method 2 After decelerating at the near-point dog ON, move the designated distance, and complete the
machine home position return.
6: Data set method The position where the machine home position return has been made will be the home position.
7: Scale origin signal After deceleration stop at the near-point dog ON, move to the opposite direction against the home
detection method position return direction, and move to the home position return direction after deceleration stop once
at the detection of the first zero signal. Then, it stops at the detected nearest zero signal, and
completes the machine home position return.
