Example:
CPLCTID[X2,X1]=5
Boundary conditions
• A coupling factor of zero (CPLNUM=0) is a permissible value. In this case, the leading
• CPLDEN=0 is not a valid value and is rejected with alarm 16790.
• CPLNUM, CPLDEN und CPLCTID can be programmed in synchronous actions.
• Availability of non-linear coupling relationships (CPLCTID) depends on selected options
2.5.4.2 Coupling relationship (CPLSETVAL)
The following value can be derived from either of the following:
• position setpoint of the leading axis
• speed setpoint of the leading axis
• position actual value of the leading axis
The following couplings can be programmed accordingly:
• Setpoint value coupling
• Speed coupling
• Actual value coupling

axis/spindle does not provide a path component for the following axis/spindle, however, it
remains a part of the coupling. Contrary to the switched-off state, the leading axis/spindle
still has an influence on the following axis/spindle. This affects, for example, reactions to
errors, limit switches and NC/PLC interface signals.
(see topic "Preconditions" in "Summarized Descriptions").
; The leading axis specific coupling component of the coupling
of the following axis X2 to the leading axis X1 is calculated
with curve table No. 5.
