On the CAN bus the IDs listed in Table 7 are assigned as follows:
Table 7: IDs used on the CAN bus
The IDs are calculated from the basic ID which is set via the DIP switches and the offset describing
the corresponding message (see Table 3).
When the process data length is set at 3, the drive inverter will receive exactly three process output
data words and send three process input data words to the master control. Fig. 12 illustrates this
concept.

Fig. 12: Configuring for three process data words
The content of the process data words is defined by the Process Output Data Description 1...3 and
Process Input Data Description 1...3 parameters.
