  Operation 

 

Fig. 1-2 Manual reference position return 

Moreover, the tool can be moved into the reference position with the program code, and the 

method is called as the automatic reference position return. 

●

   

MPG feeding

 

The tool can be moved the distance corresponding to the rotation angle by rotating MPG. (See 

Section 5.4) .   

●

   

Manual operation

 

The tool can be moved along each axis by the switches on the machine operation panel, buttons 

or MPG. 

 

Fig.1-3 

（

）

Manual (manual continuous) feed (refer to 5.2 for details.) 

During the button is pressed, the tool can be continuously moved.   

（

2

）

Incremental feed (refer to 5.3 for details.)   

         After the button is pressed, the tool is only moved for certain distance when the button is 

pressed once.   

●

   

DNC running:

 The program can be directly read from the external input/output equipment for 

running the machine; however, the program isn’t saved into CNC memory, and the operation is called 
as DNC running (Refer to 6.3 for details.)
