Detailed description
2.5 Generic coupling
2.5.3.5 Implicit creation and deletion of coupling modules
Switch-on commands may also be used to create coupling modules (without prior definition
with CPDEF).
Programming example
CPON=(X2) CPLA[X2]=(X1)
or
CPLON[X2]=(X1)
CPOF=(X2)
Boundary conditions
• Implicitly created coupling modules (via switch-on commands) are deleted once they are
• Implicitly created coupling modules can be transformed into explicit coupling modules
with the following instruction CPDEF/CPLDEF. In this case CPOF does not delete the
coupling module and the data is retained.

completely deactivated (CPOF).
Advantage: Deleting them with CPDEL/CPLDEL is not necessary.
Disadvantage (possibly): All coupling properties which were set with CPOF are lost.
; Creates a coupling module for following axis X2 with
leading axis X1 and activates the coupling module.
; After its deactivation, the implicitly created coupling
module is deleted.
Special functions: Axis Couplings and ESR (M3)
