1.2 Motor Control Board

1.2.1 Hardware Specifications

Table 1-2 shows the system specifications of the motor control boards. The two motor control boards are the
42-mm square board and 85-mm square board for the motors with the corresponding dimensions. An MCU
(64-pin RX24T) and RDC IC, both made by Renesas Electronics, are mounted on both of them, and the 2-
phase stepping motors with resolvers can be driven in fast decay mode. Though the RDC IC made by
Renesas Electronics has a function for correcting errors in the resolver angle, that function is not used on the
42-mm and 85-mm square boards of this demo system.
For detailed circuit diagrams of each board, see R12TU0106 for the 42-mm square board and R12TU0109
for the 85-mm square board.
