July 2013 6.4 Axis-error compensation 689
The figure below shows the relationships for a specific acceleration of the axis
j. Axis i is to be compensated, where the compensation value depends on the
position of the axis k:
Considerations
before using CTC
Considerations before using CTC:
What kind of cross talk is to be expected?
Which dependencies in the workspace (position) concerning cross talk are
to be expected?
The cross talk to be expected must then be measured.
Only axes that are controlled by the same DSP can be compensated with each
other for software option 141 (CTC). This means that such axes cannot be
distributed to drive-control motherboards.
