-10GM, FX
2N
-20GM)
1) Outline of positioning
When an interrupt signal for the first step is input from the outside while the machine is
operating in the speed mode, the operation speed decreases. When an interrupt signal for
the second step is input, the positioning mode is selected, and the machine stops after
moving for the specified distance.
2) Operating procedure
c
The machine starts to move by the start command. When the interrupt signal X0 (for the
X axis) for the first step is turned ON from the outside, the operation speed decreases.
When the interrupt signal X1 (for the X axis) for the second step is turned ON, the
machine moves by the specified incremental quantity from that point, then stops.

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

Ox0, N0 cod92(SET) x0; Sets the current value to "0".
N1 cod72(DINT) x1000 f1200 f200; Moves the machine at the speed "1200" until
X0 turns on. When X0 turns on, the machine
reduces the speed from "1,200" to "200",
moves by the incremental quantity "1,000" at
the speed "200", then stops.
