Coupling Relationship (Cplsetval) - Siemens SINUMERIK 840D sl Function Manual

M3: Coupled axes
8.5 Generic coupling
Programming: Curve table
When programming a table number, a previously activated non-linear coupling relationship
(coupling factor) is deactivated.
The leading axis specific coupling component for the leading value of the leading axis is
calculated using the specified curve table.

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 (Page 368)").
8.5.5.2

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

CPLCTID[FAx,LAx]= <value>
Coupling Lead Curve Table Id
Specifies the number of the curve table to be used to calculate how the
leading axis/spindle must act on the following axis/spindle.
