CPMBRAKE[FAx]= <value>
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 552)")
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.
1 - 31 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)
14.5 Generic coupling
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.
