13.3 CAN bus addressing and termination
The MBC-110 logic controller and the two MMC-120 motor
controllers exchange data via a CAN bus.
Each of the controllers must have a fixed CAN address assigned to
it. Additionally, a termination resistor must be activated at both
ends of the bus to prevent interference.
Fig. 28: CAN bus termination
Each controller is equipped with a DIP switch block. The
termination is activated or deactivated using DIP switch 1. The
CAN addresses are set using the DIP switches 2 to 4 of each
controller.
