Feedrate of the tool can be specified by the move distance of the block and
inverse time (FRN).
Speed: mm/min (metric input)
inch/min (inch input)
Distance:mm (metric input)
inch (inch input)
Speed: mm/min (metric input)
inch/min (inch input)
Circle radius:
mm (metric input)
inch (inch input)
CAUTION
In circular interpolation, the distance is not an actual
distance o f the block but the speed is calculated from the
circle radius.

011 NO FEEDRATE COM-
MANDED
Feedrate was not commanded to a
cutting feed, F0 was specified or the
feedrate calculated (less than 0.001
mm/min, for metric input or less than
0.00001 inch for inch input) becomes
less than an allowable range.
