CANopen interface

The interface design follows the CiA DS301 CANopen
standard. The address on delivery is 63.
The CAN bus is set up as a 2‐wire line (CAN H and
CAN L) (see ISO 11898).
Important
You must connect bus termination resistors (each 120 W)
at the start and at the end of the bus. The electronics do
not contain a bus termination resistor for CANopen.

Fig. 5.2 CAN bus wiring
The bus wiring structure was chosen to minimize the
length of the stub lines. To make wiring simpler, the con­
nections for CAN H (High) and CAN L (Low) are dupli­
cated. This means that at a node, you can connect the
lines of the previous one and the lines to the next node to
