Sync phase position
The phase position defines the zero time of the application in relation to the
synchronisation signal (bus cycle). As the PDO processing is an inherent part of the system
part of the application, the instant of PDO acceptance is also shifted by a change of the
phase position.
 If the setting is 0, the application starts simultaneously with the synchronisation
signal.
 If the setting is > 0, the start of the application in relation to the synchronisation signal
is earlier by the time set (the phase position acts negatively).
Example: If the phase position is set to 400 μs, the system part of the application starts
400 μs before the synchronisation signal occurs.
Sync tolerance
Time slot for monitoring the synchronisation signal via the system block LS_SyncInput.
 LS_SyncInput - status information for the sync telegram
( 264)
 If the last synchronisation signal was within this time slot around the expected value,
the output SYNC_bSyncInsideWindow of the system block LS_SyncInput is set to TRUE.
 This setting has no influence on the synchronisation itself.
Sync PLL increment
If the cycle times of the synchronisation signal and the phase-locking loop (PLL) deviate
from each other, the setting in C01124 defines the increment by which the phase-locking
loop can be corrected.
 For the system bus as synchronisation source, the recommended time setting in the
case of occurring deviations is 109 ns (Lenze setting).

Note!
The effect of the sync phase position can be influenced by the application cycle
set in C01130 . If the Lenze setting is selected for C01130 , the behaviour is the
same as known from previous versions.
