- Page 2 FET/IC 3-phase inverter using sensor-less field oriented control with space vector pulse width modulation. Figure 1 shows an overview of the EPC9147C board detailing connections and various human interfaces that measures 120 mm x 71 mm (L x W).
- Page 3 ST Nucleo board – press this button once to start the motor and press it again to stop the motor. • Speed potentiometer on EPC9147C – This knob can be used to change the motor speed. By default, the potentiometer is not interfaced in original ST firmware, so it is up to the customer to modify the ST firmware to interface the potentiometer to use it as target speed setting analog interface.
- Page 4 Internal/External 3.3 V Power Jumper Setting The EPC9147C is provided with a jumper (J7) that, when it is mounted (by default), allows the 3.3 V power supply to be fed by the Power Board. If Jumper J7 is not mounted, the EPC9147C 3.3 V (and the ST Nucleo 3.3V) power must be supplied by an external 3.3 V power supply connected to the connector J6.
