Movement Track
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 the rising edge of HOM-SW After
that, decelerate, reverse, and run at low speed in negative direction to the position where HOM-
SW is invalid, then decelerate to stop, and then run at low speed in positive direction.
Stop after falling edge of SW.
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. Stop after falling edge.
c) When starting to return, HOM-SW=1, start the return at a forward low speed, and stop after
encountering the falling edge of HOM-SW.
