12.9 CANopen
CANopen® is an internaonally approved communicaon protocol which is designed for com-
mercial and industrial automaon applicaons. High data transfer rates in connecon with
ecient data formang provide for the coordinaon of moon control devices in mul-axis
applicaons.

Detailed informaon on CANopen can be found on the web page of the CAN in Automa-
on (CiA) user organisaon: hp://www.can-cia.org

Informaon about the dimensioning of a CANopen network can be found in the congura-
on document for the inverter.
Precondions
•
The control unit (CU) of the inverter is provided with CANopen.
•
The network is terminated by one bus terminang resistor each at the rst and last physi-
cal node. See "Typical topologies”.
•
The DIP switches for node address, baud rate and bus terminang resistor are correctly
set, see: 4Basic seng and opons ^ 348
•
The required EDS device descripon les for the inverters to be put into operaon are loa-
ded in the master (PLC).

Details
•
The implementaon of the CANopen communicaon prole (CiA DS301, version 4.02)
enables baud rates of 20 kbps to 1 Mbps.
•
For establishing a simple network connecon, the inverter provides predened control and
status words for these proles.

There are also addional mappable data words to individually control the inverter:
•
The inverter control is precongured via a CiA 402-compliant control word.
