The value range of the feedrates depends on the computational resolution selected. If
MD10200 INT_INCR_PER_MM (computational resolution for linear positions)
(1,000 incr./mm) or MD10210 INT_INCR_PER_DEG (computational resolution for angular
positions) (1,000 incr./degree) are assigned their default values, the following range of
values can be programmed with the specified resolution:
Value range for path feed F: Metric system:
0.001 v F v 999,999.999 [mm/min, mm/rev, degree/min, degree/rev].
Value range for spindle speed S:
0.001 v S v 999,999.999 [rev/min]
If the computational resolution is increased/decreased by a factor of 10, the value ranges
change accordingly (maximum number of decimal points is constant).
7.1.2 Traversing ranges
The range of values of the traversing range depends on the computational resolution
selected.
If MD10200 INT_INCR_PER_MM (computational resolution for linear positions) (1000
incr./mm) or MD10210 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 specified resolution:
Table 7- 1 Traversing ranges of axes
G71 [mm, degrees] G70 [inch, degrees]
Linear axes X, Y, Z, etc. ± 999,999.999 ± 399,999.999
Rotary axes A, B, C, etc. ± 999,999.999 ± 999,999.999
Interpolation parameters I, J, K ± 999,999.999 ± 399,999.999
The unit of measurement of rotary axes is always degrees.
If the calculation resolution is increased/decreased by a factor of 10, the value ranges
change accordingly (maximum number of decimal points is constant).
The traversing range can be limited by software limit switches and working areas, see
Chapter "Axis Monitoring (A3)".
The traversing range for rotary axes can be limited via machine data, see Chapter "Rotary
Axes (R2)".
