8 Process data transfer

Process data are transmitted by means of EtherCAT datagrams ( 56) via the process data channel.

The Inverter Drive 8400 is controlled by means of the process data.

The transmission of process data is time-critical.

Process data are transferred cyclically between the Controller (EtherCAT master) and the inverters

(slaves) (continuous exchange of current input and output data).

The master can directly access the process data. In the PLC for instance, the data are directly stored

in the I/O area.

Up to 16 process data words (16 bits/word) per direction can be exchanged.

Process data are not saved in the Inverter Drive 8400.

Process data are for instance setpoints, actual values, control words, and status words.
