Co-Ordinate Reference (Cpfrs) - Siemens SINUMERIK 840D Function Manual

Coupling reference:
Example:
Programming
CPLSETVAL[X2,X1]="CMDPOS"
Constraints
For a coupling module speed coupling cannot be activated simultaneously with setpoint or
actual value coupling of another leading axis.
14.5.5.3

Co-ordinate reference (CPFRS):

The co-ordinate reference of the following axis/spindle specifies in which co-ordinate reference
system the coupling component resulting from the coupling is applied. in the base co-ordinate
system or in the machine co-ordinate system.
It is further specified which co-ordinate reference the leading values of the leading axis spindle
must have. When a transformation is active and when the machine co-ordinate system is
specified as co-ordinate reference (CPFRS="MCS"), the initial transformation values are taken
as leading values.
