As shown in the figure above, the mechanical slider slides in the positive limit direction (positive
direction), and Z in the left position along the left side of the origin switch signal, that is, outside
the effective range of the origin switch signal.
When the machine is within the origin switch range (mechanical motion trajectory 2), the origin
can be found by directly running in the negative direction. When the machine is outside the origin
switch (mechanical motion track 1 and 3), the machine runs in a constant direction (positive
direction) toward the limit switch. According to the detected sequence of the origin switch and
limit switch, find the movement track and the origin.
Origin mode 8: Refer to origin mode of origin switch, Z phase signal and positive limit (adopt Z
phase signal of positive origin switch right of left edge)
As shown in the figure above, the mechanical slider slides in the positive limit direction (positive
