When the bit is not 0, the random PWM function works. The larger the value, the wider the fluctuation range and the flatter the noise spectrum. It should be noted that after opening the random carrier, the electromagnetic noise of the motor will not necessarily be reduced, and the actual noise perception varies from person to person.

845 +The speed dynamic response characteristic of vector control can be adjusted by setting the proportional coefficient and integration time of the speed regulator. Proportional increase
846 +
847 +If the integration time is reduced, the dynamic response of the speed loop can be accelerated. The system may oscillate if the proportional gain is too large or the integration time is too small.
848 +
849 +Recommended adjustment method:
850 +
851 +If the Factory parameters cannot meet the requirements, fine-tune the Factory default parameters: first increase the proportional gain to ensure that the system does not oscillate; Then the integration time is reduced so that the system has both faster response characteristics and smaller overshoot.
852 +
