a) POT=0 when starting to return, start returning at high speed in positive direction, after
encountering the rising edge of POT, decelerate, reverse, and run at low speed in negative
direction.
The rst Z pulse after the falling edge of POT stops.
b) When starting to return, POT=1, start to return at a negative low speed, and stop at the rst Z
pulse after encountering the falling edge of POT.

Z-phase Signal
a) When starting to return, HOM-SW=0, start the 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, and stop at the rst Z pulse after encountering the falling edge of HOM-SW.
b) When starting to return, HOM-SW=1, start the return at a negative low speed, and stop at the
rst Z pulse after encountering the falling edge of HOM-SW.
