Hi everyone,
I just finally installed my 2018 Haas VF-2SS in my garage, connect my brand new Phase Perfect PT-030 to the house 200 amp service, then straight to the CNC mill. My machine max FLA is 70 amps, I wire it with 3/0 cable from electrical cabinet to the PP, then 1/0 from PP to the machine. Machine was checked and leveled by HAAS HFO. All the speeds,rapids, feeds work fine, no alarms or sudden shutdowns, at first I notice that worklight LED is flickering, but I didn't pay too much attention to that. I runned the machine for a day or two and then started to hear mills multi tap transformer humming, it got loud especially when it got warmer. Called the HFO tech, they said that they had not much have heard/ had troubles with their machines transformer humming and advice me to check incoming voltages. It's supposed to be all in 120's volts range. I find that T3 to ground is 212 volts, while T1&T2 to ground is 125V. Called the phase perfect support team, they said that T3- to ground 212 volts is normal, and that noise/harmonics can be present in the T3 leg that was made by the converter. They suggest to double check the grounding, and install single phase EMI filter before the converter. I would do that. I understand that it should fix the LED flickering, but would it fix the machine transformer loud humming. I'm really afraid to damage any electrical components on my pretty new mill. I think I bought the best available converter in the market because I heard so much good things about it. I would be glad to hear any suggestions/advice from anyone who had anything like that with their equipment in the past. (sorry for grammatical mistakes)
Thanks, Andrei
