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 da
ta.
•
The sync telegram is the trigg
er 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 t
elegrams 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 PDOs, the value 0x80 mus
t be entered in the 11-bit idener in the Lenze seng
(and in compliance with the CANopen specicaon). This means that all inverters are set to
the same sync telegram by de
fault.
•
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").
