I-1005
This object can be used to activate the generation of sync telegrams and to write the identifier
value.
• This object relates to codes C00367
and C00368.
Creating sync telegrams
Sync telegrams are created by setting bit 30 (see below) to "1". The time between the sync telegrams
can be set using the object I-1006
.
Writing identifiers
To receive PDOs, the value 0x80 must be entered in the 11-bit identifier in the Lenze setting (and
according to CANopen specification) . This means that all
modules are by default set to the same
sync telegram.
• If sync telegrams are only to be received by certain
communication modules, their identifiers
can be entered with values up to and including 0x07FF.
• The identifier can only be changed if the communication module does not send any sync
telegrams (bit 30 = "0").
• How to change the identifier:
• Deactivate identifier (set bit 30 to "0").
• Change identifier.
• Activate identifier (set bit 30 to "1").
