Denominator of coupl. fact. KF
KF = numerator/denominator
preset: 1
Denominator must be positive.
----
Denominator is 0, if instead of
the numerator

number of a curve table is
specified.
Synchronized position for
specified leading axis
Default: 0
Synchronized position for
specified following axis
Default: 0

Number of leading axes
defined with EGDEF. 0 if no
axis has been defined as a
following axis with EGDEF.
Axis identifier of leading axis
whose index n has been
specified.
Determine power-on state of a
leading axis:
0: Switched off
1: activated
