Canopen Interface - HBM PAD4001A Mode D'emploi

Interfaces
7.2

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. 7.2 CAN bus wiring
Use a cable with a characteristic impedance of approx.
120 Ω. HBM cable 1-KAB173 meets these requirements
and also has the same protection class (IP68/69K) as the
PAD housing.
The bus wiring structure was chosen to minimize the
length of the stub lines.
