Arc center correction.

CIRINERR
Maximum absolute radius error permitted.
Possible values: From 0 to 99999.9999 mm or degrees / from 0 to 3937.00787 inch.
Default value: 0.0100 mm or degrees / 0.00039 inch.
Associated variable: (V.)[ch].MPG.CIRINERR
See general machine parameter CIRINFACT.
CIRINFACT
Maximum relative radius error permitted.
Possible values: from 0 to 100.0 %.
Default value: 0.1 %.
Associated variable: (V.)[ch].MPG.CIRINFACT
These parameters set the conditions for correcting the center position in circular
interpolations. On circular interpolations, the CNC calculates the radius of the starting point
and end point of the tool path. Theoretically, they should be the same; but these parameters
may be used to set the maximum difference allowed between both radius.
Parameter CIRINERR indicates the maximum absolute error allowed. Parameter
CIRINFACT indicates the maximum relative error allowed (% of the radius). Both parameters
are taken into account. The CNC will show the relevant error message when this difference
between them is greater than CIRINERR and greater than —CIRINFACT x Radius—.
This function is controlled via program using functions G264 and G265.
