Operation
（
1
）
Press the reference position return switch , and it is one of the mode selection switch;
（
2
）
Press one of the rapid movement override switches for deceleration;
（
3
）
After pressing the feeding axis corresponding the reference position return and the direction
selection switch , the reference position return is started. The tool is
moved to the deceleration point at the rapid traverse rate (The absolute position encoder
zero return doesn’t have the deceleration point and it can be directly returned to the
reference position), and the tool is returned to the reference position at FL speed set by the
parameter. After the tool is returned to the reference position, the reference position return
finish lamp (LED) is ON;
（

）
The same operation is executed for other axes.
Note 1: The manual reference position return can only be returned to the 1st reference position, the
coordinate system is automatically set after the manual reference position return ends.
Note 2: Once the reference position return is completed, “the reference position return finish” indicator
lamp is ON, the machine tool doesn’t move unit the reference position return switch is OFF.
Note 3: When “leaving off the reference position” is executed, the reference position return finish
indicator lamp is OFF.
Note 4: The direction of each axis reference position return is set by the 5th bit of the parameter #1006.
Note 5: The 2nd bit of the parameter 1404: After setting the reference position, the reference position
return is executed in Manual mode, the tool is moved to the reference position at the rapid
feedrate or at the manual rapid feedrate.
Note 6: After setting the system reference position with the absolute encoder, the system automatically
sets the coordinate system after power on, again without setting the reference position. About
the non-absolute encoder system, the system should execute the reference position return after
power on, again.
The above mentioned is one example, please refer to the user manual from the machine tool builder
for operation.
5.2 Manual Feeding
In manual mode, press the feeding axis and the direction selection switches on the machine
operation panel and the machine tool is moved along the selected direction of the selected axis.
Each axis manual continuous feedrate is set by the parameter (#1423), and each axis manual
continuous feedrate is adjusted by the manual continuous feedrate override dial.
