Starting the Zero Point Return in the Low Region
1.
The axis travels in the reverse direction at the Approach Speed (setting parameter OL3E).
2.
When the rising edge of the DEC2 signal is detected, the axis decelerates to a stop.
3.
After decelerating to a stop, the axis travels in the forward direction at the Creep Rate (setting parame-
ter OL40).
4.
After the falling edge of the DEC2 signal is detected, the position is latched when the rising edge of the
first phase-C pulse is detected.
5.
The axis moves from the latched position by the distance set in the Zero Point Return Travel Distance
(setting parameter OL42) and stops. The machine coordinate system is established with this final
position as the zero point.
