• Generic coupling
Note
When programming, attention must be paid that the utilized CP key words within a
synchronized action are processed from left to right.
That is, unlike the programming in the part program, the effect of the various key words
depends on their order in the synchronized action.

With the help of the "Electronic gearbox" the movement of a following axis FA can be
interpolated dependent on up to five leading axes LA. From the parts program a gearbox
group can be:
– is defined.
– Switched-in
– Switched off
– Deleted
With the help of a coupling module, the motion of one axis, (_FA following axis), can be
interpolated depending on other (_leading) axes. Coupling modules can also be created
and activated in the part program and implicit synchronized actions. The coupling
modules created and activated in synchronized actions are designated as main run
couplings. The relationships between leading axis/values and the following axis are
defined for each leading axis/value by a coupling rule, either a coupling factor or a curve
table.
Each coupling property of the generic coupling can be programmed using keywords. The
following keywords are available in synchronized actions:
– CPLON Switching-on a leading axis of a coupling module
– CPLOF Switching-off a leading axis of a coupling module
– CPOF Switching-off a coupling module
– CPLNUM Counter of the coupling factor
– CPLDEN Denominator of the coupling factor
– CPLCTID Number of the curve table
– CPSETTYPE Coupling type of the existing coupling modes
