Learn the basic wiring of variable frequency drives / VFD with our electrician Steve Quist. In this video, we used the very popular Mitsubishi D700 series VFD, showing single phase and three phase wiring instructions. The VFDs showed in the video are the D720S (230V single phase) and the D720 (230V three phase). We strongly recommend using a certified electrician to set up your VFDs. If you are doing this on your own, make sure you wear protective gear and take proper precautions.

    Great basic wiring video. Single phase to 3 phased wiring explained. Thanks.
  • @user-zn2pv5nm3g
    Your video is so good, and I was moved by your professional knowledge. We are a Chinese supplier specializing in the production of frequency converters and soft start for 12 years. I hope we can have some cooperation in the future.
  • Hello Steve thank u for sharing information wht I want to know is the sattings of the frequency to run motor or water pump connections hve been easy thanks again.
  • @ravigovande2922
    Thanks for sharing the video. Nice explanation on single & 3 phase wiring. I have subscribed your channel. Where can I find the video on programming the VFD?
  • Its great job you done thanks for that can you use single phase vfd to control or power three phase motor.thanks
  • @bigdog5405
    In video you connect red and black to L1 and L2 witch are hot. Each wire provides 120v. You connect green wire as ground. Where does the neutral white wire connect ? I'm wiring a TECO E510 VFD. 240 volts single phase input power to power a 240 volt 3 phase motor.
  • @mosarfraj9713
    would you please tell connections of 3 phase motor to vfd and how the speed of 3 phase motor is varied?
  • @paulbaird1351
    By grounding via cable to a ground star bar, does having the VFD case grounded to the control panel backer not cause a ground loop by having two grounds come from the drive?

    I just added a VFD to an old CNC I have.  Its your Mitsubishi.  Thanks for showing how to get the main power cover off.  Now my problem is this.  The 4 lead wire that came off the spindle motor to the FWD rev relay only had the 3 power wires going between motor and controller.  The ground lead from the motor went straight to the grounding area of the enclosure.  Now my wire is not long enough to get to the VFD in the cabinet.  Is it good enough If I just run a grnd from the VFD to the grounding area of the cabinet?  Should I just say, start from the beginning and get a dedicated VFD to motor wire?  Wire would have to be about 8' long.
  • Please i want to buy single phase 2.2 kw vfd, will this run any 3 phase more below 2.2 kw, will some one advice, thanks great video, thanks for loading
  • @ijazhussain7386
    Hello,please also explain inverter control with relay for manual control of vfd driven motor
  • @erikkayV
    The part I am getting tripped up on is how to wire in a switch to the line side going into the vfd so I do not have to leave it on constantly. From what I can gather I will need a DPST switch rated for the correct amperage but I can not seem to find any 2 articles or opinions that say this is the correct way to configure the switch. Some say that a switch will always burn out others say they have had a switch on theirs for ages. My manual does not list any control ports for a power switch and i I understand it correctly it goes as far as saying that a switch should not be used to control the run/stop of the drive. I take that to mean that you should not use a switch to put the unit under a load not just powering the unit on but I am admittedly getting a little cautious. Any guidance would be appreciated.
  • @vitortodomais
    How do I do that VFD connection in a air compressor with a pressure switch? Thanks a lot!!!
  • @fahimasghar6375
    Nice video Sir. But you didn't tell us main things that was parameter setting and control wiring? .Thanks
  • @bisarowood
    would a 3ph VFD work on equipment like a widebelt sander or edge bander with multiple motors ?
  • @jeffiscool1805
    Good video. So these little VFD's can replace my big and heavy single phase to 3 phase converter while giving me speed control??
  • @kkji16
    hi brother . can you tell me how can i adjust external veriable of this invertr E700
  • @artiemend.3578
    Will a disconnect after the vfd but before the motor affect the performance of the vfd .
  • @arshadanees448
    Sir plz lell me how to make the connection from starting to end also what is the use of vfd in motor two 3 types vfd
