5.3.6 CAN bus operation
The CAN bus parameters can be specified in the ”CAN bus” field down on the right of the
”Service” menu. The selection of the fieldbus in this connection has to be set to
”CANOpen”, so that the CAN bus is activated and the respective bus parameters can be
specified.
Node ID
The node ID defines the identity of the CAN nodes or the CAN bus address. The option
ranges from 1 to 127.
Baud rate
In this place, the transmission speed of the CAN bus can be defined. Thereby the following
baud rates can be set:
10k, 20k, 50k, 100k, 125k, 250k, 500k, 800k and 1000k bauds
Terminal (termination R)
In order to guarantee a trouble-free data transmission, the nodes at the beginning and the
end of a bus line have to be terminated by means of a resistor, so that no reflections or
communication faults on the bus occur. If this option is selected, the terminating resistor
is automatically connected via a relay in the drive.
