Your carrier frequency, resonance which could be due to mechanical resonance, or electrical resonance due to the PWM output frequency to the motor. Vector or Volts per hertz mode settings on the 5hp VFD (variable frequency drive). It could well be a bearing or balancing issue on the fan. I would say that one should investigate all possible mechanical issues first, and then eliminate Resonance, Harmonics that could cause audible noise in the motor windings or even being amplified and transduced by the 5hp VFD itself. Was it functioning properly in the past and if so, what changed? Does the "noise" appear at certain speeds and loads. Often one has to take a look at an installation at a 30,000 ft level to narrow down the problem. Barring resonance speed issues (often fixed with skip output frequencies) and possible issues with carrier frequencies, it may be advisable to throw a scope on the output of the 5hp VFD to see if an issue exist within the firing circuit.
