1732 Lower limit RVmin for feedrate clamping by arc radius
[Data type] Word
Valid data range
IS–A, IS–B IS–C
Millimeter machine 1 mm/min 0 to 15000 0 to 12000
Inch machine 0.1 inch/min 0 to 6000 0 to 4800
When the function for clamping the feedrate by arc radius is used, the
upper limit imposed on the feedrate falls with the arc radius. If the upper
limit imposed on the feedrate is less than the lower limit imposed on the
feedrate clamping RVmin, the upper limit imposed on the feedrate is set as
RVmin.
