Coupling Mode Brake
CPMBRAKE is a bit-coded CP keyword that defines the braking behavior of
the following axis FAx for the following events:
Bit
Event
0
● NST DB31, ... DBX4.3 (feed stop / spindle stop) present
or
● CP SW limit stop is set (see "CP SW limit monitoring
(Page 428)")
Note:
Bit 0 is significant only for a "Freely programmable" coupling type
(CPSETTYPE=CP).
Value
Meaning
0
The brake is not transferred to the leading axes.
1
The brake is transferred to the leading axes depending
on the context.

Reserved
The following rules apply for the programming:
● CPMBRAKE must be programmed in one block with CPDEF or CPON (⇒
can only be programmed for an inactive coupling).
● While defining a coupling, the following values are captured without the
explicit programming of CPMBRAKE:
Bit 0 = 1 for pre-processing couplings with CPSETTYPE=CP (otherwise
bit 0 = 0)

Comment
;
Defining a coupling (lead-
ing axis Ax4 with following
axis Ax5). NST "feed stop /
spindle stop" or "CP SW lim-
it stop" should not brake
the coupling group.
