And I'm not talking about the typical high frequency noise you can hear when running the motor. I'm fine with that, but my goodness the noise the cooling fan makes is like a F18 on takeoff.
So back story, it's a Hitachi NES1 running on 220VAC 1ph input. As soon as I apply power to it, the cooling fan takes off and makes a horrendous whistling noise. currently It is not installed in an enclosure, but is just wall mounted in my shop. No where that i can find anyone else has this problem.
Has anyone here used this VFD? Am I missing a setting in the VFD to control the fan speed? I don't think the fan should be running full bore when the motor is not running.
