Setting Up the Hardware

The following table shows the target hardware for the application projects.

Setting Up MCLV2 Development Board

  • Mount the ATSAME54 Motor Control Plug In Module on U9 header.
  • Place the “External Opamp Configuration” Matrix board at J14.
  • Motor Connections:
    • Phase U - M1
    • Phase V - M2
    • Phase W - M3
  • Jumper Settings:
    • JP1 - Curr, JP2 - Curr, JP3 - Curr
    • In order to use RS232 port for X2CScope Communication JP4 - UART, JP5 - UART
    • In order to use USB port for X2CScope Communication JP4 - USB, JP5 - USB
  • Power the board with a 24V DC supply using J2 or BP1-BP2. For additional safety, it is recommended to use a current limited power supply while testing this software demonstration on a non-default hardware and motor.
