Detailed description
2.1 Velocities, traversing ranges, accuracies
2.1.2 Traversing ranges
Range of values of the traversing ranges
The range of values of the traversing range depends on the computational resolution
selected.
If machine data:
MD10200 $MN_INT_INCR_PER_MM
(computational resolution for linear positions) (1000 incr./mm)
or
MD10210 $MN_INT_INCR_PER_DEG
(computational resolution for angular positions) (1000 incr./degree)
are assigned their default values, the following range of values can be programmed with the
input resolution:
Table 2-1
Linear axes X, Y, Z, etc.
Rotary axes A, B, C, etc.
Interpolation parameters I, J, K
The unit of measurement of rotary axes is always degrees.
If the computational resolution is increased/decreased by a factor of 10, the ranges of values
change accordingly.
The traversing range can be limited by software limit switches and working areas.
