Comment
; CFAST is taken as synchronization mode of the coupling
to following axis X2.
CPFMON[FAx]= "<block change criterion>"
Coupling Following Mode On
Defines the behavior of the following axis/spindle during switch-on of
the coupling.
Type: STRING
Range of values:
"STOP" Stop
"CONT" Continue
"ADD" Additional
Default value: "STOP"
For spindles only!
An active motion of the following
spindle is stopped before switch-on.
For spindles and main traverse axes
only!
The current motion of the following
axis/spindle is taken over into the
coupling as start motion.
For spindles only!
The motion components of the cou‐
pling operate in addition to the cur‐
rently overlaid motion, i.e. the cur‐
rent motion of the following axis/
spindle is retained as overlaid mo‐
tion.
