B-64120EN/01 4.DESCRIPTION OF PARAMETERS
- 77 -
1465
Virtual radius for feedrate control about rotation axis
[Data type] 2-word axis
[Unit of data]
Increment system IS-A IS-B IS-C Unit
Metric input mm
Inch input
0.01 0.001 0.0001
inch
[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, inverse time feed (G93), feed per
revolution (G94), threading, AI advanced preview
control, AI contour control
