a) When starting to return, HOM-SW=0, start the return at high speed in 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 and stop, and then go negative
again Run at low speed and stop at the rst Z pulse after encountering the rising edge of HW.
b) When starting to return, HOM-SW=1, start returning at low speed in positive direction, after
encountering the falling edge of HOM-SW, decelerate, reverse, and run at low speed in negative
direction, and stop at the rst Z pulse after encountering the rising edge of HOM-SW.
7.8.2.11 Return to origin mode 7: forward return, look for the falling edge of the origin
sensor and Z pulse signal, and automatically reverse when encountering the positive limit

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