Active compressor COMPON
With an active compressor COMPON the following applies when several blocks are joined to
form a spline segment:
FNORM:
The F word of the last block in the group applies to the spline segment.
FLIN:
The F word of the last block in the group applies to the spline segment.
The programmed F value applies until the end of the segment and is then approached
linearly.
FCUB:
The generated feed spline deviates from the programmed end points by an amount not
exceeding the value set in machine data
$MC_COMPESS_VELO_TOL.
F=FPO(…,…,…)
These blocks are not compressed.
