CPLCTID[X2,X1]=5
Supplementary conditions
● A coupling factor of zero (CPLNUM=0) is a permissible value. In this case, the leading 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.
● CPLDEN=0 is not a valid value and is rejected with alarm.
● CPLNUM, CPLDEN and CPLCTID can be programmed in synchronous actions.
● Availability of non-linear coupling relationships (CPLCTID) depends on selected options
(see Section "Requirements").
14.5.5.2

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

Comment
; The leading axis specific coupling component of the cou-
pling of the following axis X2 to the leading axis X1 is
calculated with curve table No. 5.
