Note:
Only the function block specific to the phase synchronization
mode is described in detail below. The detailed descriptions of
the other function blocks are contained in section "Basic
Functions of the Synchronization Modes"
In the operating mode "phase synchronization with real/virtual master
axis" the internal position command value (P-0-0434) is generated by
addition of the synchronous position command value (x
sync
) and the
position command value from the synchronization process (x
sync_process
).

Note:
In the synchronized status (P-0-0089; bit 8 = 1) the following
applies:
P-0-0434 = x
sync
+ S-0-0048 (because x
sync_process
= S-0-0048)
The synchronous position command value (x
sync
) is calculated in terms of
the selected master axis polarity (
P-0-0108, Master drive polarity
) and
the scaling type that was set (
S-0-0076, Position data scaling type
),
