120-degree commutation using trapezoidal waves
Detected by three phase induced voltage of motor
5kHz
Single Direction
1000rpm to 7200 rpm
The Fo signal (forced shut-down signal) of the IPM is input
to the NMI pin of the MCU. Thus, if the Fo signal goes low,
the three-phase output is forcibly stopped and the
three-phase output pins are placed in the high-impedance
state.
