1731 Arc radius value corresponding to a maximum feedrate
[Data type] 2–word
[Unit of data]
Unit IS–A IS–B Unit
Linear axis (millimeter machine)
0.01 0.001 mm
Linear axis (inch machine)
0.001 0.0001 inch
[Valid data range] 1000 to 99999999
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
[Data type] Word
Valid data range

Millimeter machine 1 mm/min 0 to 15000
Inch machine 0.1 inch/min 0 to 6000
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.
1762
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.
1763
Minimum speed in exponential acceleration/deceleration for cutting feed in the
advanced preview control mode
