The value range of the feed rates depends on the selected computational resolution
When the 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)
is assigned its default values, the following range of values can be programmed with the
specified resolution:
Range of values for path feedrate F and geometry axes:
Metric system:
Inch system:
0.001 ≤ F ≤ 999,999.999
[mm/min, mm/rev, degrees/min, degrees/rev] 0.001 ≤ F ≤ 399,999.999 [inch/min, inch/rev]
Range of values for feedrate for positioning axes:
Metric system:
Inch system:
0.001 ≤ FA ≤ 999,999.999
[mm/min, mm/rev, degrees/min, degrees/rev] 0.001 ≤ FA ≤ 399,999.999
[inch/min, inch/rev]
Range of values for spindle speed S:
0.001 ≤ S ≤ 999,999.999 [rpm]
If the computational resolution is increased/decreased by a factor of 10, the ranges of values
change accordingly.
