FANUC Series 30i-MODEL A
Rotary table dynamic fixture offset
1.2 Fixture offset screen
The fixture offset screen is either a fixture offset (ACT) screen for verifying
the currently selected fixture offset value or a fixture offset screen for setting
and verifying eight fixture offset value sets.
・ Ative Fixture offset screen
・
1. Press the［OFFSET/SETTING］function key
2. Press the continuous menu key sevral times, until The [F-ACT] soft key
appears.
3. Press the [F-ACT] soft key.
The fixture offset (ACT) screen displays.
This screen displays the currently selected fixture offset number (P) and
fixture offset vector.
