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.

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.

Exponential acceleration/deceleration time constant for cutting feed in the ad-
vanced preview control mode
[Data type] Word axis
[Unit of data] 1 ms
[Valid data range] 0 to 4000
Set an exponential acceleration/deceleration time constant for cutting
feed in the advanced preview control mode.
