Synchronization Object - Sync - WEG CFW-11 Communications Manual

When transmitting a message, three pieces of information are sent with the eight data bytes: the CiA error code, the
error register
object 1001h (
byte 0 byte 1
CIA error code
This object is always active in the CFW-11 and therefore it will always report the occurrence of inverter errors to the
network. There is a single parameter that allows reading the object COB-ID, i.e. which identifier for the sent error
message telegrams.
5.5 Synchronization Object – SYNC
This object is transmitted with the purpose of allowing the synchronization of events among the CANopen network
devices. It is transmitted by a SYNC producer, and the devices that detect its transmission are named SYNC
consumers
The CFW-11 has the function of a SYNC consumer and, therefore, it can program its PDOs to be synchronous. As
described in Table 5.6, synchronous PDOs are those related to the synchronization object, thus they can be
programmed to be transmitted or updated based in this object.
The SYNC message transmitted by the producer does not have any data in its data field, because its purpose is to
provide a time base for the other objects. There is an object in the CFW-11 for the configuration of the COB-ID of
the SYNC consumer.
