1460
Upper limit of feedrate for the one–digit F code command (F1 to F4)
1461
Upper limit of feedrate for the one–digit F code command (F5 to F9)

Millimeter machine 1 mm/min 6 to 15000 6 to 12000
Inch machine 0.1 inch/min 6 to 6000 6 to 4800
Rotaion axis 1 deg/min 6 to 15000 6 to 12000
Set the upper limit of feedrate for the F1-digit feed command.
As the feedrate increases by turning the manual pulse generator, the
feedrate is clamped when it reaches the upper limit set. If an F1-digit feed
command F1 to F4 is executed, the upper limit is that set in parameter
1460. If an F1-digit command F5 to F9 is executed, the upper limit is that
set in parameter 1461.
1465
Virtual radius for feedrate control about rotation axis

[Valid data range] 0 to 99999999
Set the radius of a virtual circle when using such a control method that the
feedrate of a rotation axis is converted to a travel speed on a circle of a
virtual radius.
NOTE
1 Note that the increment system remains unchanged
regardless of whether metric input or inch input is used.
2 This function is enabled when bit 0 (ROTx) of parameter No.
1006 and bit 0 (RFDx) of parameter No. 1408 are set to 1.
3 Be careful when setting bit 0 (RFDx) of parameter No. 1408
and parameter No. 1465 (virtual radius). In particular, when
this function is used with a small virtual radius value, axis
movement speeds up.
4 If a large value is set for the amount of travel and parameter
No. 1465 (virtual radius), an alarm (P/S 5307: Internal data
exceeded an allowable range.) is issued.
5 This function cannot be used in the following modes:
Rapid traverse, feed per revolution (G94), threading, AI
look–ahead control, high–speed remote buffer A,
high–speed remote buffer B
