Note:
The IKA links are processed in descending sequence, i.e. IKA32 first, then IKA31 etc. until
IKA1.
Example:
R00 is the output quantity of IKA12 and the input quantity of IKA11 and IKA13. R00 as result
(output quantity) of the link of IKA12 is therefore included in the same interpolation cycle in
IKA11 as input quantity. In IKA 13, however, R00 is taken into account only in the next
interpolation cycle. With IK13, linking of the R parameter to an axis can result in an
interpolation-cycle and speed-dependent offset.
