Project NameDescription
mclv2_sam_rh707_pim.X

MCLV2 Development Board

ATSAMRH707 Plug-in module

Hurst Motor with encoder

Setting Up MCLV2 Development Board

  • Mount the ATSAMRH707 Motor Control Plug In Module on U9 header.
  • Place the “External Opamp Configuration” Matrix board at J14
  • Motor Connections:
    • Phase U - M1 (White colored wire)
    • Phase V - M2 (Black colored wire)
    • Phase W - M3 (Red colored wire)

  • Encoder Connections: Connect encoder wires as shown below

    • 1 : +5V (Red colored wire)
    • 2 : HA (White colored wire)
    • 3 : HB (Blue colored wire)
    • 8 : GND (Black colored wire)
  • 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.
  • Complete Setup
