CPMVDI[FAx]= <value>
Coupling Mode VDI Signal
CPMVDI is a bit-coded CP keyword, which defines the response of the cou‐
pling module of following axis FAx to certain NC/PLC interface signals.
The bit combination operators B_OR, B_AND, B_NOT, and B_XOR can be
used to set individual bits.
Comment
Definition of a spindle coupling:
Leading spindle S1 with following spindle S2
Activation of the coupling with following
spindle S2. NST "feed stop / spindle stop"
or "CP SW limit stop" should brake the cou-
pling group.
