I just replaced a PowerFlex4 that was showing a F012 error on a good motor. The replacement drive worked fine but I wanted to adjust the PWM setting to make the drive less noisy as long as there is no detriment to the motor.
The default freq is 4hkz and is quite audible and in a range that is objectionable in the closed room it sits in. Putting it at 15khz puts it out of my old hearing range but its probably driving some dogs in the neighborhood nuts.
Whats the criteria for changing the PWM freq? Certainly there is a better reason to change it than just auditory concerns.
