PIC32CM MC00 Motor DIM

Hurst Motor

Setting Up MCLV-48V-300W Development Board

  • Remove resistors R1, R3, R5, and R7 of PIC32CM MC00 Motor Control Dual In-Line Module ( DIM ) as shown below:
  • Populate resistors R2, R4, R6, and R8 of PIC32CM MC00 Motor Control DIM as shown below:
  • Connect the jumper J3 of PIC32CM MC00 DIM to 2-3 position as shown below.
  • Insert the PIC32CM MC00 Motor Control Dual In-Line Module into the J8 interface header.
  • Connect the Motor: Attach the 3-phase connections of the motor to the J4 header.
  • Power the Board: Supply the board with 24V DC using the J1 or J3 (+, -) header.For added safety, it is recommended to use a current-limited power supply while testing this software demonstration on non-default hardware and motors.

Running the Application

  1. Build and Program the application using its IDE
  2. Press switch SW1 to start the motor
  3. Vary potentiometer to change the speed of the motor
  4. Press switch SW1 to stop the motor
  5. Press switch SW2 to change the direction of the motor
  6. Press switch SW1 again to start the motor
  7. Monitor graphs on X2Cscope
Refer to the following tables for switch and LED details:
SwitchDescription
Switch SW1To start or stop the motor
Switch SW2To change the direction of rotation.

Direction toggle command is accepted only when motor is stationary.

LED D2 StatusDescription
