M- Bus
M-Bus
Each M-Bussed motor is connected through a ribbon cable that contains three wires (power, ground and signal). A command for motor movement is sent over the signal wire and addressed to a specific motor. All of the motor processors receive the Signal, but only the addressed motor will respond and move to the desired position.
Because of the unique address stored in the processor, all bussed motors have a unique part number and cannot be interchanged.
