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 reference axis buffer
memory addresses.
• For circular interpolation in axis 1 and axis 2, set in the axis 1 buffer memory
address [60, 61]
• For circular interpolation in axis 2 and axis 3, set in the axis 2 buffer memory
address [210, 211]
•
For circular interpolation in axis 3 and axis 1, set in the axis 3 buffer memory
address [360, 361]
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.
