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" should brake the
coupling group.
CPMVDI[FAx]= <value>
Coupling Mode VDI Signal
CPMVDI is a bit-coded CP keyword, which defines the response of the
coupling 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
; Defining a coupling (leading
axis Ax4 with following axis
Ax5). NST "feed stop /
spindle stop" should not
brake the coupling group.
