a) When starting to return, HOM-SW=0 and it is located on the negative side of the origin sensor
position, and starts to return at high speed in the positive direction. After encountering the rising
edge of HOM-SW, decelerate, reverse, and run at low speed in the negative direction until the
HOM-SW is invalid. After the position, it decelerates to stop, and then runs forward at a low speed,
and stops at the rst Z pulse after the rising edge of HOM-SW.
b) When starting to return, HOM -SW=0 and it is located on the positive side of the origin sensor,
and starts to return at high speed in the positive direction. After encountering the rising edge of
POT, decelerate, reverse, and run at high speed in the negative direction; Decelerate after falling
edge, reverse and forward at low speed, encounter HOM-
The rst Z pulse after SW rises stops.
c) When starting to return, HOM-SW=1, start the return at low speed in negative direction, after
encountering the falling edge of HOM-SW, decelerate, reverse, and run at low speed in the forward
direction, and stop at the rst Z pulse after encountering the rising edge of HOM-SW.
