2.1 Quick Start Guide

The MCF8315PWPEVM requires a power supply source, which has a recommended operating range from 4.5V to 35V. To set up and power the EVM, follow the sequence below:

  1. Connect motor phases to A, B, and C on connector J8.
  2. Do not turn on the power supply yet. Connect the motor supply to VBAT/VM and PGND on connector J7.
    1. To enable reverse polarity protection and Pi filter, connect to VBAT. Note that when connecting to VBAT, VM will be VM – 0.7V less, due to a diode drop in the reverse-polarity protection circuit.
    2. To disable reverse-polarity protection and the Pi filter, connect to the VM.
  3. Select J3 to 5V_USB and J5 to 3V3COM to power MSP430 from the USB power supply.
  4. Connect the micro-USB cable to the computer.
  5. Turn the potentiometer fully clockwise to set the motor to zero speed upon power-up.
  6. Flip the switch S1 to the right to configure BRAKE = RUN and switch S2 to the right to configure DRVOFF = Driver output ON
  7. Turn on the motor power supply.
  8. Use the Motor Studio GUI (as shown in Section 3) to configure and tune the device registers and spin up the motor.
