1731 Arc radius value corresponding to a maximum feedrate
[Data type] 2-word
[Unit of data]
Increment system IS-A IS-B IS-C Unit
Linear axis (millimeter machine) 0.01 0.001 0.0001 mm
Linear axis (inch machine) 0.001 0.0001 0.00001 inch
[Valid data range] 1000 to 99999999
Set the arc radius corresponding to the maximum feedrate set in
parameter No.1730.
1732 Minimum value (RV min) for arc radius-based feedrate clamp
[Data type] Word
[Unit of data, valid data range]
Valid data range
Increment system Unit of data
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
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.
1740
Critical angle subtended by two blocks for automatic corner deceleration
[Data type] 2-word
[Unit of data] 0.001 deg
[Valid data range] 0 to 180000
Set a critical angle to be subtended by two blocks for corner
deceleration when the angle-based automatic corner deceleration
function is used.
The angle subtended by two blocks is defined as q in the examples
shown below.
Block A (G01)
Block B (G01)
ngle subtended by two straight lines
Block A (G02)
Block B(G01)
ngle subtended by an arc and its tangent
