  • VFD ?

    http://cgi.ebay.com/ws/eBayISAPI.dll...sPageName=WDVW

    THIS WOULD BE A HECK OF A BUY.

    Before buying anything like that make sure you can get a manual! Since he doesn't have it I'd check the manufacturer and see if one is available for download. A VFD without a manual is a pain!

      Not a lot of info on it although a web search links them with Yaskawa.

      3~ in but could run on single phase derated.

        Do you have 440 3phase to run it? The guys on the other board say the logic circuits need the indicated voltage to operate correctly. I personally don't know.

          That doesn't apply. The logic circuitry will be derived from two of the phases and is only 10 or 24 volts at 10 mA

            You gotta watch these eBay autions for inverters etc. Some of them are first generation technology where noisy six step output and few control amenities.

            I suggest that if you can't find a manual on-line for a VFD auction (or any industrial electronics for that matter) you give it a pass no matter how cheap the price. No docs = no way to tinker with the settingss.

              Mr. Wolf-

              Do you have 480V single phase to run it? I know that you can usually run a 3 phase inverter on single phase, allowing for appropriate derate, but I'm less certain that you can run a 380-480V 3 phase drive on 240 single phase. I do know from purchasing drives in the past that 240 drives for a given horsepower size will typically cost more than a 480V. I assume that the added cost is for higher current SCR's or IGBT's.

              take care
