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 12V
DC
and 24V
DC
. 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 exVdc (from 12 to 24 Vdc) to the inverter DC
link.
