9.4.2 Linear interpolation (FX
2N
-20GM)
1) Outline of positioning
The machine moves to the target address in a linear route, waits until an auxiliary unit fin-
ishes its work, then returns to the zero point.
2) Operating procedure
c
The machine returns to the zero point by the start command only at the first time.
d
The machine moves to the target address in a linear route.
e
The output Y0 turns on and off.
f
The machine returns to the zero point (0, 0).

5) Parameter
Set the positioning parameter No. 16 (mechanical zero point address) to "0" for both the X
and Y axes. For other parameters, refer to Paragraph 9.2.4.
