EtherCAT system bus

16.4 EtherCAT system bus
The system bus enables the use of several inverters of the i900 series in a network.
The system bus of the inverter uses the EtherCAT® protocol.
EtherCAT® is a registered trademark and patented technology, licensed by Beckhoff Auto-

ration document for the inverter.
Preconditions
Only inverters of the i900 series are connected to the system bus.
•
A maximum of 16 nodes including the master can be connected via the system bus.
•
No further accessories are connected to the system bus.
•
The inverters are not parameterised as CiA 402 motion drives. Selection of a technology
•
application:
40x4000
The »EASY Starter« does not allow a configuration of the system bus cross communication.
•
The technology application set in the inverter is not identified.
Details
The inverter can act as a system bus master or system bus slave.
•
The system bus is prepared, i. e. a configuration is not required.
•
The master assigns an identical master value to all system bus nodes (slaves).
•
The »EASY Starter« is sufficient ...
•
to parameterise the devices in the network;
•
to configure the process data individually.
