Hardware Connections

Motor Control Blockset™ supports the following hardware configurations:

  1. F28069 control card configuration

  2. LAUNCHXL-F28069M configuration

  3. LAUNCHXL-F28379D configuration

  4. C2000 MCU Resolver Eval Kit [R2]

F28069 control card configuration

The configuration includes the following hardware components:

  • Texas Instruments™ DRV8312-69M-KIT inverter board

  • Texas Instruments F28069 microcontroller control card

  • Motor BLY171D (supports both Hall and quadrature encoder sensors)

  • Motor BLY172S (supports Hall sensor)

  • Quadrature encoder

  • DC power supply

Note

Due to auxiliary power supply related hardware issues, the DRV8312-69M-KIT does not support the position sensors connected to some motors (for example, Teknic M-2310P motor).

The following steps describe the hardware connections for the F28069 control card configuration:

  1. Connect the F28069 control card to J1 of DRV8312-69M-KIT inverter board.

  2. Connect the motor three phases, to MOA, MOB, and MOC on the inverter board.

  3. Connect the DC power supply (24V) to PVDDIN on the inverter board.

Warning

Be careful when connecting PVDD and GND to the positive and negative connections of the DC power supply. A reverse connection can damage the hardware components.

The following step describes about interfacing the quadrature encoder sensor:

  • Connect the quadrature encoder pins (G, I, A, 5V, B) to J4 on the inverter board.

To implement position-sensing by using Hall sensor, use a motor that has inbuilt Hall sensors (for example, BLY171D and BLY172S). The following steps describe the steps to interface the Hall sensor:

  • Connect the Hall sensor encoder output to J10 on the inverter board.

We recommend the following jumper settings for DRV8312-69M-KIT inverter board when working with Motor Control Blockset. You can customize these settings depending on the application requirements.

The following step describes about interfacing the quadrature encoder sensor:

  • Connect the quadrature encoder pins (G, I, A, 5V, B) to QEP_A on the LAUNCHXL controller board.

To implement position-sensing by using Hall sensor, use a motor that has inbuilt Hall sensors (for example, Teknic motor M-2310P, BLY171D and BLY172S). The following steps describe the steps to interface the Hall sensor:

Instructions for Dyno (Dual Motor) Setup

  1. Connect the three phases of Motor1 and Motor2, to MOTA, MOTB, and MOTC on the corresponding BOOSTXL inverter boards.

  2. Attach the BOOSTXL inverter board (connected to Motor1) to J1, J2, J3, J4 on the LAUNCHXL controller board.

    Note

    Attach the inverter board to the controller board such that J1, J2 of BOOSTXL aligns with J1, J2 of LAUNCHXL.

  3. Attach the BOOSTXL inverter board (connected to Motor2) to J5, J6, J7, J8 on the LAUNCHXL controller board.

    Note

    Attach the inverter board to the controller board such that J1, J2 of BOOSTXL aligns with J5, J6 of LAUNCHXL.

  4. Connect the DC power supply (24V) to PVDD and GND on both BOOSTXL inverter boards.

    Note

    Connect the PVDD and GND on the BOOSTXL boards (for MOTOR1 and MOTOR2) to the same power supply. When one motor consumes power, the second motor generates power. If you connect both motors to the same power supply, the power generated by one motor is consumed by the other motor. The DC power supply delivers power only for the losses.

  5. Connect the quadrature encoder pins of Motor1 (G, I, A, 5V, B) to QEP_A on the LAUNCHXL controller board.

  6. Connect the quadrature encoder pins of Motor2 (G, I, A, 5V, B) to QEP_B on the LAUNCHXL controller board.

Warning

Be careful when connecting PVDD and GND to the positive and negative connections of the DC power supply. A reverse connection can damage the hardware components.
