The PP877K 3BSE069274R1 timed interrupt program is used to sample and calibrate the current ia and ib of the A and B phases of the Hall current sensor, as well as calculate the magnetic field orientation angle based on the principle of magnetic field orientation control. The angle is then adjusted, and a PWM signal is generated to control the position and speed loops.

The power driven protection interrupt program is mainly used to detect the fault output of intelligent power modules.

The zero pulse capture interrupt program of the photoelectric encoder can accurately capture the feedback zero pulse of the encoder, and PP877K 3BSE069274R1 can obtain the correction value of the vector transformation orientation angle of the AC permanent magnet synchronous motor.

The data exchange program mainly includes communication programs with the upper computer, EEPRoM parameter reading, digital display programs, etc. The storage controller keyboard value for parameters.
