Basics of the embedded fieldbus interface
The cyclic communication between a fieldbus system and the drive consists of
16-bit data words or 32-bit data words. The diagram below illustrates the
operation of the CANopen embedded fieldbus interface. The signals transferred
in the cyclic communication are explained further below the diagram.
