Configured coupling
For the configured coupling, the LS and FS are defined via machine data. The configured
spindles cannot be changed in the part program. The coupling can be parameterized in the
part program using
User-defined coupling

A coupling is defined in its entirety by:
COUPDEF(<FS>,<LS>,<TFS
Following spindle (FS) and leading spindle (LS)
The coupling is uniquely defined using the axis names for the FS and LS. The axis names
have to be programmed with every
modal and only have to be programmed if they change.
Example:
COUPDEF(S2,S1)
Transformation ratio
The transformation ratio is defined as the speed ration between FS and LS:
Following spindle / leading spindle = numerator/denominator
The numerator must be programmed. The denominator must not be programmed. The
default value 1.0 is then set for the denominator.
Example:
Following spindle S2 and leading spindle S1, transformation ratio = 1/1
COUPDEF(S2, S1, 1.0)
