Frequency converter for a small compressor
I am trying to control a small compressor by an off-the-shelf standard Frequency Converter -FC- (which I heard that it is not advised, but I don't know why). And the compressor makes too much noise and FC draws too much current which I assume is a sign that something is teribly wrong.
Has anybody know why does a compressor work well with its own FC but not with a standard off-the-shelf FC? is it the carrier frequency? or something about not so smooth FC output ?
Cheers to all
