CPFMON Behavior of the following axis
when switching on
CPFMON[FAx]= "<switch-on behavior>"
"<switch-on
behavior>":
"STOP" For spindles only!
An active motion of the fol‐
lowing spindle is stopped
before switch-on.
"CONT" For spindles and main tra‐
verse axes only!
The current motion of the
following axis/spindle is tak‐
en over into the coupling as
start motion.
"ADD" For spindles only!
The motion components of
the coupling operate in ad‐
dition to the currently over‐
laid motion, i.e. the current
motion of the following axis/
spindle is retained as over‐
laid motion.
CPFMOF Behavior of the following axis at
complete switch-off
CPFMOF[FAx]="<switch-off behavior>"
"<switch-off
behavior>":
"STOP" Stop of a following axis/
spindle.
An active overlaid motion is
also braked to standstill.
The coupling is then
opened
"CONT" For spindles and main tra‐
verse axes only!
The following spindle con‐
tinues to traverse at the
speed/velocity that applied
at the instant of deactiva‐
tion.
CPFPOS + CPOF Switch-off position of the follow‐
ing axis when switching off
CPOF=(FAx) CPFPOS[FAx]=<value>
