a) When starting to return, HOM-SW=0 and it is located on the positive side of the position of the
origin sensor, and it starts to return at a high speed in the negative direction. When it encounters
the lower part of HOM-SW After the falling edge, decelerate, reverse, and run at low speed in the
forward direction, and stop at the rst Z pulse after the rising edge of HOM-SW.
b) HOM-SW=0 when starting to return, and it is located on the negative side of the origin sensor
position, and starts to return at a high speed in negative direction, and encounters the rising edge
of NOT. Then, decelerate, reverse, and run at high speed in forward direction; after encountering
the rising edge of HOM-SW, decelerate, reverse, and run at low speed in negative direction until
HOM-SW is invalid. After the position, it decelerates and stops, and then runs forward at a low
speed, and stops at the rst Z pulse after the rising edge of HOM-SW.
c) HOM-SW=1 when starting to return, start returning at low speed in negative direction, after
encountering the falling edge of HOM-SW, decelerate, reverse, and run at low speed in forward
direction, The rst Z pulse after encountering the rising edge of HOM-SW stops.
