    Show us your VFD conversions/installations

    If you have the name/picture of the VFD, then some guidance could be provided as to programming. HY VFD's PD003 Main Frequency 60.00 PD004 Base Frequency 60.00 PD005 Max Operating Frequency 60.00 PD075 Higher Analog Frequency 60.00 The issue is a VFD is not a 3 phase power source to run...

    Actually modern VFD's you do not turn off the phase loss on the input, if so you can burn the VFD up and it also voids the warranty. I have done 100's of VFD installs with both Hitachi and Yakawa VFD's , you do not disable the input phase loss. You need to read the specific manual for the model...

    I am assuming that the motor runs continuously and the lathe has a clutch drive. Most 3 phase input VFDs can be used with a single phase input, they needed to be derated by ~1.7 and it is also recommended to use a DC choke to decrease the fusing/breaker requirement and also the THD generated...

    Milter saw recommendations

    I have the DEWALT 12-Inch Sliding Compound Miter Saw, Double Bevel (DWS780) with Miter Saw Stand (DWX723). At the time the stand was free with purchase of the miter saw, works well and doesn't take up much space. Had the non-slider version for years, but the slider handles bigger stock. No...

    Budget air compressor

    There are a number of postings of older compressor tanks failing and causing seriously bodily injury, more frequent in the cheaper compressors because people fail to drain them and they can sit for many months/years corroding away. Buying a replacement compressor would be the safest option, and...

    Quincy 325 vs 340 need help deciding

    No doubt the Quincy 325/340 will last for many years, but maybe consider the amount of hours of use and CFM you plan for you may not need that level of durability. Most splash lubricated air pumps on the better compressors are rated at 20,000+ hours. I have the Champion HR5-8 and it will outlast...

    Can I use capacitors to start well pump with a less that ideal size of generator?

    They do make soft starters for both 1 and 3 phase motors, but with single phase motors it causes the start capacitor to remain in the circuit longer and could cause a quick demise. Best bet is too call the pump manufacturer tech. at Red Lion to see if they have any recommendations. Alternative...

    Help selecting a 5HP single phase compressor motor

    I have the Champion HR5-8 with an R15B pump, the range of Hp is 3-7.5 Hp, so going to a 5Hp you will need a new smaller pulley if you change the pump speed or motor shaft size. As pointed out they are inexpensive. The stock motor on my Champion (purchased 2 years ago) is a Leeson single phase 5...

    Help identify compressor part.

    The very large hex nut on the bottom is part of the check valve that holds the pressure in the tank. Release the tank pressure and take the valve assembly apart, you should be able to use some thread sealant and reinstall the hex nut. In addition the valves often will get debris, rust flakes...

    Quality air compressor needed.

    If you are looking at a high output low RPM pump (575 RPM = quiet and will last a long time) then the Champion HRV7-8 7.5 or VRV7-8-1P-230 is also worth checking out. I would get the after cooler no matter which compressor you get, makes a big difference in the temperature and pulls out the...

    Hi Mike, I moved to southern CA a few months ago, decided it was "easier" to sell the 1340GT and order an ERL-1340 to be delivered to CA. Always liked that lathe, but it is much heavier and difficult to move. Briefly considered the RML-1440, but it is another 1000lbs over the ERL and quite a bit...

    ERL-1340 Lathe VFD conversion. Stock system followed by replacement Yaskawa VFD with custom control system. Braking resistor is behind the mounting panel. Control system uses an electronic position control to trigger the braking for threading/turning to a fixed position accurate to better than...

    Most VFDs are rated for a range of voltages so for the Hitachi WJ200 series they come in a low voltage L series which is typically 200-240V and high voltage H series which are rated at 380-480V. As previously mentioned, the output voltage cannot be greater than the input voltage You set the VFD...

    Air compressor pipe leakdown question

    I use a Rapidair Maxline system, although my previous was all copper. Total runs with ~75' with 4+ drops. In general I see a leak down of 5 PSI/day, and this has mostly been isolated to leakage of the quick disconnects. I do have a real system which is about 25 years old but still seems to hold...
