4.8.3 Continuous Interpolation
With continuous interpolation the controller continuously executes
multiple interpolation paths including straight line, arc and helical
interpolations described above. You do continuous interpolation by
giving multiple interpolation commands in sequence. These
commands shall be saved in buffer of the controller queueing for
execution.
Figure 4-47: Illustration on continuous interpolation (Buffer) movement
For continuous interpolation the only restriction is that the
dimension and axis ID must remain the same. E.g., 3D straight
line must link with 3D arc but not 2D arc and axis to be used must
be the same as well. This controller provides seven setup
methods for speed blending between two adjacent paths.
1. Aborting and blending
2. Aborting forced
3. Aborting stop
4. Buffered
5. Blending when deceleration start
6. Blending when residue-distance met
7. Blending when residue-distance % met
