Sync phase position
The phase position defines the zero point of time for the application relating to the
synchronisation signal (bus cycle). Since PDO processing is integrated in the system part of
the application, the instant of the PDO acceptance also changes if the phase position is
changed.
If 0 is set, the application is started together with the synchronisation signal.
If a value > 0 is set, the application starts by the set time interval before the
synchronisation signal arrives (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 arrives.
Sync tolerance
Time slot for monitoring the synchronisation signal via the LS_SyncInput system block.
If the last synchronisation signal has been within this time slot around the expected
value, the SYNC_bSyncInsideWindow output of the LS_SyncInput system block is set to
TRUE.
This setting does not affect the synchronisation process.
Sync-PLL increment
If the cycle times of the synchronisation signal and the phase-locking loop (PLL) differ from
each other, the setting in
defines the increment with which the phase-locking loop
can be readjusted.
If the system bus (CANopen) is used as synchronisation source, the recommended time
increment for deviations is 109 ns (Lenze setting).
Note!
From Servo Drive 9400 software version V3.0:
The effect of the sync phase position can be influenced by the application cycle
, the behaviour remains as before.
