Pr.41 Allowable circular interpolation error width
With the "allowable circular interpolation error width", the allowable error range of
the calculated arc path and end point address is set. If the error of the calculated
arc path and end point address is within the set range, circular interpolation will be
carried out to the set end point address while compensating the error with spiral
interpolation.
The allowable circular interpolation error width is set in the following axis buffer
memory addresses.
If axis 1 is the reference axis, set in the axis 1 buffer memory address
[60, 61].
If axis 2 is the reference axis, set in the axis 2 buffer memory address
[210, 211].
If axis 3 is the reference axis, set in the axis 3 buffer memory address
[360, 361].
If axis 4 is the reference axis, set in the axis 4 buffer memory address
[510, 511].
Path with spiral interpolation
Start point address
With circular interpolation control using the center point designation, the arc
path calculated with the start point address and center point address and the
end point address may deviate.
