We found a new one, 12-16 kHz hissing sound coming from a brand new, idling (not running) Yaskawa GA800. Their tech support states the noise is coming from the line filter which strikes me as a bit odd. I would expect this type of noise from electrolytic capacitors in a switching power supply (old capacitors).
