5 Baud rate setting/line lengths
The transmission speed of the CANopen communication module CM-CAN can be set
via the parameter
CAN Baud rate 385.
Parameter Setting
No. Description Min. Max. Fact. sett.
385 CAN Baud rate 1 8 6
The transmission rate is a function of a variety of application-specific parameters. The
line length of the communication network limits the transmission speed due to the
signal running time of the CANopen protocols.
CANopen interface
Operation mode Function max. Line length
1 - 10 kBaud Transmission rate 10 kBaud 5000 meter
2 - 20 kBaud Transmission rate 20 kBaud 2500 meter
3 - 50 kBaud Transmission rate 50 kBaud 1000 meter
4 - 100 kBaud Transmission rate 100 kBaud 500 meter
5 - 125 kBaud Transmission rate 125 kBaud 500 meter
6 - 250 kBaud Transmission rate 250 kBaud 250 meter
7 - 500 kBaud Transmission rate 500 kBaud 100 meter
8 - 1000 kBaud Transmission rate 1000 kBaud 25 meter
6 Setting node address
The CANopen protocol supports a maximum of 127 nodes in a communication
network. Each frequency inverter is given a node ID, which may only exist once in the
system, for its unambiguous identification. The setting of the station address is done
via the parameter
CAN Node Number 387.
Parameter Setting
No. Description Min. Max. Fact. sett.
387 CAN Node Number 0 127 0
Note:
The factory setting
CAN Node Number 387 = 0 means that the
CANopen interface has been deactivated.
After the node address has been set via parameter
CAN Node Number
387, a reset is automatically triggered on the frequency inverter, by
which the setting for the station address is taken on.
