1.4 Traverse ranges
For all five 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 related to the machine datum (MP960.x). The
momentary software limit switch range is selected by the markers (M2817, M2816) and activated
by the strobe-marker (M2824).
The software limit switches for axes of rotation are not active unless a value of 0 is entered in
machine parameter MP810 (see section "Display and operation").
The MOD-function "Axis-limit" can be used to enter an additional limitation for each traverse range.
