In order to establish a machine coordinate system correctly during machine working period, a
machine reference point (measuring beginning) will be set within the moving range of each
coordinate axis. In machine start-up, generally returning to the reference point will be executed
automatically or manually, i.e. machine tool will return to its measuring beginning (X, Y, Z=0) to
establish the machine coordinate system. Machine reference point can be coincident with the
machine origin (in the default system setting), or not.
When origin switch works normally, if spindle moves away from origin switch direction in the
process of returning to the machine origin, the value of parameter
“X/Y/Z direction in back to refer”
(coarse positioning direction) should be modified, please refer to question 2 in section 3.4.5 when
the moving direction of machine is incorrect during backing to the machine origin. The setting value
of parameters parameter
“X/Y/Z direction in back to refer” is opposite to the direction of fine
positioning. If the speed of returning to the machine origin is quite slow, you can adjust values of
parameter
“X/Y/Z speed in back to refer” (coarse positioning speed) properly. “Trace back” (retract)
refers to a certain distance away from origin to leave the signal sensitive zone of origin switch after
backing to machine origin ends.

X-axis screw pitch
It is used to analyze the switch distance of
coarse positioning and fine positioning in
homing.
0.001~9999.9 mm
Y-axis screw pitch
Z-axis screw pitch
Since screw pitch is related with the machine specification, users need to measure it before setting
the parameters in actual operation.
3.4.5 FAQ & Troubleshooting
1) Origin signal can not be detected in the process of returning to machine origin.
It is generally caused by origin switch. The debugging & adjusting steps are shown in Fig. 3-14.
