2.11.4 Interface Part

The CLX-82x0 series provides clear interface specifications of all components and modules in the system,
due to the design strategy for common-use and standardization. The main interface between the Main
Controller and the Engine Controller uses two pairs of drawer type board-to-board connectors, which
makes it possible to have a sliding connection to the Main Controller. The Main Controller and the IP
Controller use a PCIe interface to achieve high performance. In the connection of mechanical parts,
standard harnesses are used to reduce manufacturing costs and to allow convenient maintenance.

Controllers require connections to all of the system units such as the BLDC motor, Stepping Motor, Clutch,
Solenoid, Sensor, and other PBAs. The Engine Controller contains various types of connectors, to deliver
electronic signals through signal wires. The signal wires provide electronic control signals that are used for
starting and stopping the motors, operating clutches, activating solenoids, sensing the unit state, etc.
