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