8.5 Generic coupling
Constraints
● The coupling characteristics set with CPMRESET is retained until the coupling module is
deleted with (CPDEL).
● For the coupling type (CPSETTYPE="TRAIL", "LEAD", "EG" or "COUP") the response is
defined by the following machine data during RESET:
MD20110 $MC_RESET_MODE_MASK (definition of initial control system settings after
RESET/TP-End)
→ See Section "Defaults" in " Coupling Types (CPSETTYPE) (Page 419) ".

Condition at parts program start (CPMSTART)

At part program start the coupling can be activated, deactivated or the current status can be
retained. The behavior can be set separately for each coupling module.

CPMSTART[FAx]= <value>
Coupling Mode Start
Defines the behavior of a coupling at part program start.
Type: STRING
Range of values:
"NONE" The current state of the coupling is retained.
"ON" When the appropriate coupling module is created, the cou‐
pling is switched on. All defined leading axis relationships
are activated. This is also performed when all or parts of
these leading axis relationships are active, i.e. resynchro‐
nization is performed even with a completely activated
coupling.
"OF" The coupling is switched off. When the relevant coupling
module was created without an explicit definition (CPDEF),
the coupling module is deleted. Otherwise it is retained,
i.e. it can still be used.
"DEL" The coupling is deactivated and then deleted.
Default value: "NONE"
Comment
; At part program start, coupling to following axis X2 is
switched on.
