Synchronisaon of PDOs via sync telegram
During cyclic transmission, one or more PDOs are transmied/received in xed me intervals.
An addional specic telegram, the so-called sync telegram, is used for synchronising cyclic
process data.
•
The sync telegram is the trigger point for the transmission of process data from the slaves
to the master and for the acceptance of process data from the master in the slaves.
•
For sync-controlled process data processing, the sync telegram must be generated accord-
ingly.
•
The response to a sync telegram is determined by the transmission type selected.
Generang the sync telegram:
•
0x1005 can be used to acvate the generaon of sync telegrams and to write the idener
value.
•
Sync telegrams are created when bit 30 (see below) is set to "1".
•
The interval between sync telegrams is to be set in 0x1006.
Wring ideners:
•
To receive sync telegrams, the value 0x80 must be entered in the 11-bit idener in the
default seng (and in compliance with the CANopen specicaon). This means that all
inverters are set to the same sync telegram by default.
•
If sync telegrams are only to be received by specic nodes, their ideners can be entered
with a value of up to and including 0x07FF.
•
The idener can only be changed if the inverter does not send any sync telegrams
(0x1005, Bit 30 = "0").

Idener for sync telegram.
How to change the idener:
1.
Deacvate Sync: Set bit 30 to "0".
2.
Change idener.
3.
Acvate Sync: Set bit 30 to "1".

Cycle me for sync telegrams.
•
With the seng "0", no sync telegrams are generated.
•
The set me is internally rounded up to the next mulple of 10 ms.
The shortest possible cycle me thus is 10 ms.

How to change the idener:

Change idener and reset PDO to "valid" (bit 31 = "0").
