Generic coupling
● When a coupling module is activated in a synchronized action, the following axis must
already be active in the channel and be in the state "neutral axis " or "axis already assigned
to the part program of the channel". The corresponding axis state can be generated, if
necessary, in the synchronized action by programming GET[<following axis>].
● The commands of the generic coupling CP ... are processed directly in synchronized
actions by the coupling module. The command therefore takes effect immediately.
● With the programming of a coupling factor (CPLNUM, CPLDEN) or table number (CPLCTID),
a previously activated non-linear coupling relationship, e.g. a curve table, is deactivated.
Generic coupling: Using the TRAIL, LEAD, EG or COUP coupling type.
If in the framework of the generic coupling, a behavior corresponding to one of the known
coupling types "Coupled motion", "Master value coupling", "Electronic gear" or "Synchronous
spindle" is required, the command CPSETTYPE is also possible in synchronized actions when
creating or defining the coupling module:
CPSETTYPE[FAx] = <coupling type>
<Coupling type>
CP
TRAIL
LEAD
EG
COUP
Supplementary conditions
Synchronism status of a following axis
The system variable $AA_SYNC[<axis>] can be used to read the synchronism status of a
following axis in the part program or synchronized action.
