CPFMSON[FAx]= "<synchronization mode>"
Coupling Following Mode Strategy On
Determines the synchronization mode during coupling.
Type: STRING
Range of values:
"CFAST" Closed Coupling

; Activation of coupling to following axis
X2. 100 is taken as synchronized
position of following axis and 200 for
leading axis X1.
; Leading axis X1 is traversed to
position 280.
; The current position X1=280 is taken
as synchronized position of the
leading axis. The previously active
synchronized position of the leading
axis (200) becomes ineffective.
The coupling is closed time-
optimized.
The coupling is only closed
when the following axis
position, required according to
the coupling rule, is in the
range of the current following
axis position.
The next tooth gap is
approached path-optimized.
