3.17 CAN bus wiring
The wiring of the CAN bus communication should be provided in such a way that the following rules
are observed:
The maximum length of the CAN bus depends on the communication speed. For a speed of
250 kbps, which is used on the CAN1 bus (extension modules, ECU) and CAN2 bus if it is
switched to 32C mode, the maximum length is 200 m. If the CAN2 bus is switched to 8C mode
the speed is 50 kbps and the maximum length is 800 m.
The bus must be wired in linear form with termination resistors at both ends. No nodes are
allowed except on the controller terminals.
NOTE:
A termination resistor at the CAN is already implemented on the PCB. For connecting, close
the jumper near the appropriate CAN terminal.
Use a cable with following parameters:
