FX Series Positioning Controllers Program Examples 9
9-11
9.3.5 Interrupt stop (FX
2N
-10GM, FX
2N
-20GM)
1) Outline of positioning
When the interrupt input X3 (X6 in the FX
2N
-20GM) turns on, the machine decelerates and
stops, then proceeds to the next step while ignoring the remaining distance.
2) Operating procedure
c
The machine returns to the zero point by the start command only at the first time. After
that, the machine moves to the target position.
d
When the interrupt input X3 turns on during operation, the machine decelerates and
stops, then proceeds to the next step while ignoring the remaining distance.
e
After the output Y0 turns on and off, the machine returns to the address "0".
3)Operation chart
4)Program (FX
2N
-10GM)
* In the FX
2N
-20GM, change this portion to "O0, N0".
5) Parameter
Set the positioning parameter No. 16 (mechanical zero point address) to "0". For other
parameters, refer to Paragraph 9.2.4.
Caution
If this program is executed in the FX
2N
-20GM, the Y axis (which is not controlled in this pro-
gram) cannot be controlled because instructions for simultaneous 2-axis operation are actually
used.
