(3) From USB connector
5V power is supplied from the USB connector (Type-C) on the CPU board. Use a USB adapter capable of
outputting 1A or more so that the motor can be driven sufficiently.
Figure 4-12 Power supply from USB connector
It is also possible to supply power from the USB connector on the CPU board and the DC jack or terminal
block on the inverter board at the same time. In this case, the MCU drive voltage of 3.3V and the gate driver
drive voltage are generated from the USB supply of 5V, while the motor drive voltage is supplied from the DC
jack or terminal block. Please refer to Table 4-8 for the power supply conditions and each voltage generation.

*1 Motor drive current of 1 A or more may be required for each inverter board.
*2 When connecting two inverter boards to the CPU board and also inputting an external power supply to
INV2, it is necessary to supply an external power supply (which can be different from INV2) to INV1 as well,
or to supply USB 5V to the CPU board.
