The synchronization source is selected automatically by the
inverter.
The OS is synchronized via CANopen. Factory setting.
The OS is synchronized via Systembus.
The OS is not synchronized with other devices.
Operation mode Auto: The selection is done via this decision table:
Synchronization via CANopen
Synchronization via Systembus
No Synchronization activated.
The CANopen “active status for synchronization” is recognized by the parameter set-
ting 387 CAN Node Number >0 and a running synchronous PDO.
The Systembus “active status for synchronization” is recognized by the parameter
setting 900 Systembus Node ID >0. Also parameter 1180 Synchronization
has to be set
to SYNC or an RxPDO.
The parameter 1451
CANopen OS Synctime can be used to shift the point of the
synchronization inside of 1 ms. When you experience noises from a mo
tor, shifting
the
CANopen OS Synctime
can result in a better behavior.
1453 OS SyncSource Act shows the active Synchronization source
Please refer to objects 0x1005 COB-ID SYNC object, 0x1006 Communication cycle
period and 0x1007 Synchronous window length for CANopen Synchronization.
For the VPlus Scope Function the following sources are available for diagnosis:
731 -
B: Sync. OS <-> Sysbus Ok
1 = Synchronization OS to Systembus OK,
0 = Synchronization OS to Systembus not OK
852-
Shows the Synchronization cycle. Should show
the set SYNC time or TxPDO time of the send-
853
SysBus SYNC position 1ms
Task [us]
Shows the Synchronization time inside 1 ms.
Should remain constant with small fluctuations.
854-
B: Sync. OS <-> CANopen Ok
1 = Synchronization OS to CANopen OK,
0 = Synchronization OS to CANopen not OK
848-
Shows the Synchronization cycle. Should show
the set SYNC time of object 0x1006.
849-
CANopen SYNC position 1ms
Task [us]
Shows the Synchronization time inside 1 ms.
Should remain constant with small fluctuations.
