parameter
Explanation
FGROUP Channel axis
identifiers
Variable F value reference: defines the axes to which the path feed refers.
Maximum axis number: 8
The default setting for the F value reference is activated with FGROUP ( ) without
parameters.

Preparatory instruction for
the definition of a tangential
follow-up: The tangent for the
follow-up is determined by
the two master axes
specified. The coupling factor
specifies the relationship
between a change in the
angle of tangent and the
following axis. It is usually 1.
