Couplings (Cp - Siemens SINUMERIK 840D sl Function Manual

3.7.18 Couplings (CP..., LEAD..., TRAIL..., CTAB...)
The commands listed in Section "Language elements for synchronized actions and technology
cycles (Page 60)" can be programmed in synchronized actions for the functions coupled motion
(TRAIL...), curve tables (CTAB...), master value coupling (LEAD...) and generic coupling
(CP...):
Note
Generic coupling
Note that the "generic coupling" CP ... commands are always executed in synchronized
actions in the sequence of the programming from left to right. This means that in contrast to
the programming in the part program, the effect of the various commands depends on their
sequence in the synchronized action.
Curve tables
The CTAB and CTABINV commands can be used in the condition and in the action.

Coupled motion
When the coupling is activated from the synchronized action, the leading axis can be in motion.
In this case the following axis is accelerated up to the set velocity. The position of the leading
axis at the time of synchronization of the velocity is the starting position for coupled-axis motion.
