    1. Introduction The low-voltage starter kit for motor control (MC-LVKIT-714) is a complete 3-phase motor control evaluation system for NEC Electronics’ microcontroller-type, application-specific standard products (ASSPs) for motor control. The kit contains all necessary hardware and software to quickly set up and run a low-voltage brushless DC motor (BLDCM).

    Motor Control I/O Board User’s Manual For the instruction descriptions, refer to the 78K/0 Series Instruction User’s Manual (U12326E) 3. Hardware Setup The kit can be purchased as one unit with all three boards connected as shown below: To attach the motor, connect the phase U, V and W terminals to the J3 connector block on the MC- PWR-LV power board and the Hall sensor terminals to the J5 connector block on the MC-IO control board.
  • Page 9 The software to run the motor is programmed into the microcontroller’s flash memory. After the motor is connected, the program is ready to run the motor as soon as the 15V power supply is plugged into J6 of the MC-IO board and power switch SW1 on the MC-PWR-LV power module is turned ON.

    Motor Control I/O Board User’s Manual To control the motor from a GUI on your PC, connect a serial cable to the J9 RS-232 port on the MC-IO board and rebuild the code with the GUI macro option as described later in this manual. Three seconds after power up, the LED displays the current set speed.
