TNC 360 1 Machine Axes 4-15
1.4 Traverse ranges
For all four axes, three different software traverse ranges can be defined by machine parameters
(e.g. for pendulum machining). The traverse ranges are defined by so-called software limit switches.
The input values for the software limit switches are referenced to the machine datum. The
momentary software limit switch range is selected by the markers (M2817, M2816) and activated
by the strobe marker M2824.
The MOD function "Axis limit" can be used to enter an additional limitation for each traverse range.
In the setting for one traverse range, the software limit switches that are entered via MOD function
as well as the datum are effective for all traverse ranges that are selected through the PLC.
Traverse ranges 1 to 3:
Entry:
Linear axis:
– 30 000.000 to + 30 000.000 [mm]
Rotary axis: – 30 000.000 to + 30 000.000 [°]
