bus
addressing and termination
The MBC-111 logic controller and the MMC-120 motor controller
exchange data via a CAN bus line. The MMC-120 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.
Setting the CAN address and termination is performed by DIP
switches for both control devices.
The following DIP switch settings are correct:
