The training class I just finished today was really great. I now have a good understanding of vfds.
I cannot wait to take this knowledge into the field.
One question though: Carrier Frequency. From the class my understandning is that by changing the frequency I will basically alter the 'sound' of the motor.
Is that the only thing that will occur when the carrier frequency is changed? Any tips on finding an 'ideal' frequency (if there is such a thing).
I have an 460vac 800HP motor that sounds fine to me, but the customer doesn't like the sound (thinks it's too high pitched). Though its running fine. I figured that by changing the way it sounds a bit, it might relieve some undue stress from my customers shoulders. (silly I know, but it does bother him, so if I can help then why not).
