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