Backgauge position. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Backgauge position. When a negative sign is programmed this backgauge dimension is
an incremental dimension. The incremental dimension is subtracted from the actual X-
axis position. Therefore this parameter can also be used as a chaining measure.

Only in case you have a configuration with a R-axis.

The function key (‘gauge func’) appears when you put the cursor bar on this X-axis parameter.

4.e

If you press ‘gauge func’ a window appears with three programmable parameters.
