12.1.6 Home position return method 6
The home position return method 6 is the home return method in forward direction. The deceleration point is the
forward limit switch, and the home position is the Z signal.
(1 ) Home position return method 6 running route 1
Start in the forward direction, decelerate after touching the forward rising edge of the limit switch, find the deceleration
point, and use the first Z pulse in the reverse direction as the home position signal. The home position return method 6
running route 1 is shown in Figure 12.10.

Start in the forward limit signal and run in reverse direction, decelerate after touching the reverse falling edge of the limit
switch, find the deceleration point, and use the first Z pulse in the reverse direction as the home position signal. The home

and home position are both Z-signal.
Home position return method 8: Start in the forward direction and decelerate to 0 and stop when it touches the first Z
signal in the forward direction. The process of finding the home position signal for home position return method 8 is shown
in Figure 12.12.
