Controlcannotdetermine
centerpoint because R was
used.
If programming a radius command, R, in the same block as I, J, and/or K,
the control gives the R priority. The I, J, and/or K words are then ignored.
When programming I, J, and/or K words for the arc center, the words that
have a zero value can be omitted.
Important: The system installer can specify the maximum allowed
difference between the starting radius of the arc and the ending radius of
the arc. If the difference exceeds the allowed value set in AMP, an error
message occurs.
