-10GM)
9.4.1 Positioning by constant quantity of reciprocating motion (FX
2N
-20GM)
1) Outline of positioning
The machine moves a workpiece from the left table to the right table. Suppose that the left-
and-right direction is the X axis, and the up-and-down direction is the Y axis.
2) Operating procedure
c
The machine returns to the zero point by the start com-
mand only at the first time.
d
The machine moves down. When the clamp solenoid Y1
turns on, the machine clamps a workpiece.
e
The machine moves up, and moves to the right table.
f
The machine moves down. When the clamp solenoid Y1
turns off, the machine releases the workpiece.
g
The machine moves up, and returns to the left table.
