9.4 CANopen
CANopen® is an internaonally approved communicaon protocol which is designed for com-
mercial and industrial automaon applicaons. High data transfer rates in connecon with
ecient data formang provide for the coordinaon of moon control devices in mul-axis
applicaons.
•
Detailed informaon on CANopen can be found on the web page of the CAN in Automa-
on (CiA) user organisaon: hp://www.can-cia.org
•
Informaon about the dimensioning of a CANopen network can be found in the congura-
on document for the inverter.

Precondions
•
Control unit (CU) of the inverter is provided with CANopen.
•
The DIP switches for node address, baud rate and bus terminang resistors are set cor-
rectly. See "Basic network sengs" in the secon 4CANopen ^ 64.
•
The network is terminated by one bus terminang resistor each at the rst and last node.
See "Typical topologies" in the
secon 4CANopen ^ 64.
•
The required EDS device descripon les for the inverters to be operated are loaded in the
master.

9.4.1 Introducon
•
The implementaon of the CANopen communicaon prole (CiA DS301, version 4.02)
enables baud rates of 20 kbps to 1 Mbps.
•
For establishing a simple network connecon, the inverter provides predened control and
status words for device prole CiA 402, AC-drive prole and in LECOMformat. Addionally,
further mappable data words are provided to individually control the inverter.
•
The inverter control is precongured via a CiA 402-compliant control word.
