Configuration via CANopen
Communication settings
Described in the following chapters is how you can change the communication settings.
The controller is configured per default for node-ID 1 and a baud rate of 1 Mbaud.
Setting node-ID and baud rate
Node-ID and baud rate are dependent on the position of the S2 and S3 rotary switches and, if applicable, on objects 2005h CANopen Baudrate, and 2009h CANopen NodeID.
Rotary switch
The C5-E is equipped with two hex coding switches – similar to that shown in the following figure.
You can set the source for the CANopen node-ID and the baud rate using the combination of numbers from both rotary switches.
The following applies here: the combination of numbers is formed using rotary switches S2 and S3, where S2 represents the higher-value byte and S3 the lower-value byte
Example |
|
Switch S2 is set to the value "0h", switch S3 to the value "Fh"; the result is the value "0Fh"="16d". | |
Switch S2 is set to the value "Ah", switch S3 to the value "1h"; the result is the value "A1h"="161d". |
General
- If the rotary switch is set to the value "1", the node-ID is set to "1" and the baud rate is permanently set to 1000 kBd. In the event of problems with the configuration, communication can thereby always be established with the controller and any errors reversed.
- The changes in objects 2005h and 2009h must be stored by writing value "65766173h" in object 1010h:0Ah.
- The changes are not accepted until either
- the voltage supply is briefly disconnected or
- the CANopen message "RESET COMM" (NMT) is sent to the motor.
- The load sequence for objects 2005h and 2009h is as follows (each successive value overwrites the previous):
- The default value is loaded.
- A stored value – if present – is loaded.
- The configuration file is used if the controller has one.
- The settings of the rotary switch(es) are taken over.
Node-ID and baud rate
Number combinations of the rotary switches | Node-ID | Baud rate | |
---|---|---|---|
dec | hex | ||
0 | 0 | Object 2009h | 1 MBd fixed |
1-127 | 1-7F | Number of the rotary switches | 1 MBd fixed |
128 | 80 | Object 2009h | Object 2005h |
129-255 | 81-FF | (Number of the rotary switches)-128 | Object 2005h |
You can find the value of 2005h in the following table.

135 | 87 | 1000 |
Setting using LSS
The Layer Setting Services offers you the option to dynamically assign the node-ID and/or the baud rate via the CANopen bus. See chapter LSS protocol.
To do this, the rotary switch must be set to the position at which the node-ID and baud rate are read from the respective objects.
Establishing communication
Before starting commissioning, we recommend reading chapters Pin assignment and CANopen configuration.
