3. Power supply selection

As stated before, there are two ways to supply power to the board.

One possibility is to use directly the PC USB supply, and in this case the current you can give to the motor is limited

by the USB possibilities. A dual power USB cable is recommended to give enough power to the board.

The second possibility is to use an external voltage DC source to supply the board.

The recommended voltage values are between 12VDC and 24VDC. In this case the communication stage is insulated

from the inverter.

The selection between the two possibilities is made through three jumpers in the J2 connector, as described in the

following figure.

The first jumper configuration connects the USB ground to the inverter ground, the USB 5Vdc to the logic +5Vdc and

the output of the step-up converter (around 13Vdc) to the inverter DC link.

The second jumper configuration connects the external power supply ground to the inverter ground, the output of

the step-down converter (+5Vdc) to the logic +5Vdc and the external +Vdc (from 12 to 24 Vdc) to the inverter DC

link.
