| Project Name | Description |
|---|---|
| mclv2_sam_rh707_pim.X |
ATSAMRH707 Plug-in module |
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
Running the Application
