For the position–synchronous coupling, the slave drive takes into ac-
count the distance moved by the master drive and the position offset,
entered in P0412
After speed synchronism has been reached, the following error which
has occurred and the position offset in P0412 is moved through with
the supplementary speed in P0413.

Fig. 6-34 Position synchronism (P0410 = 2 or 4)
Contrary to the coupling to the absolute position, an offset between the
master and slave drives, existing before the coupling was established,
is no longer taken into account in the offset phase.
Reader’s note
The phases are described in Table 6-40.
