Set a maximum feedrate for the arc radius set in parameter No.1731. Set
this parameter when the arc radius–based feedrate clamping function is
enabled.

Set the arc radius corresponding to the maximum feedrate set in parameter
No.1730. Set this parameter when the arc radius–based feedrate clamping
function is enabled.
1732
Minimum value (RV min) for arc radius–based feedrate clamp

Millimeter machine 1 mm/min 0 to 15000 0 to 12000
Inch machine 0.1 inch/min 0 to 6000 0 to 4800
The arc radius–based feedrate clamping function reduces the maximum
feedrate as the arc radius decreases. When the specified maximum
feedrate is not greater than RV min (minimum value for arc radius–based
feedrate clamping), RV min is used as the maximum feedrate.
