CANopen
CANopen is an internationally approved communication protocol which is designed for com-
mercial and industrial automation applications. High data transfer rates in connection with
efficient data formatting provide for the coordination of motion control devices in multi-axis
applications.
Information about the dimensioning of a CANopen network can be found in the
configuration document for the inverter.
Preconditions
•
Control unit (CU) of the inverter is provided with Modbus/CANopen.
•
Modbus/CANopen selector at the inverter front is set to "CANopen".
8.4.1
CANopen introduction
•
The Lenze implementation of the CANopen communication profile (CiA DS301, version 4.02)
enables baud rates from 20 kbps to 1 Mbps.
•
For establishing a simple network connection, the inverter provides predefined control and
status words for device profile CiA402, AC drive profile and in LECOM format. Additionally,
further mappable data words are provided to individually control the inverter.
•
The inverter control is preconfigured via a CiA402-compliant control word.
8.4.2
CANopen node address
Each network node must be provided with a unique node address.
Details
•
The node address can be set in
0x2301:001 (PAR 510/001)
.
•
The setting that is active when the inverter is switched on is the effective setting.
•
The active node address is shown in
0x2302:001 (PAR 511/001)
.
