Interface Connections
Figure 2-3 shows the interconnections between the Distribution board, the Motor Controller
boards, the Stepper Motors, and the Position Encoders. Table 2-1 describes the interconnections
between the Distribution board and the Motor Controller. Table 2-3 describes the
interconnections between each Motor Controller and its respective stepper motor and position
encoder. The tables also identify the interconnection connector and pin assignments.
