Hitachi VFD Help

Lima9 · Aug 15, 2014

My electrician came to my house today and connected my Toolmex TUM-35D1 lathe to my Hitachi WJ200-110LF VFD (direct to the motor bypassing all the old switches). I don't have an external switch connected to the VFD yet, but I'm sure you can turn the lathe motor on and off from the keypad on the VFD. I just don't know how. I've read the manual and I still can't figure it out. Anyone have firsthand experience with this. My lathe has been sitting dormant in my garage for months and I want to see it run.

You should just have to hit the run button and dial in the speed you want.

Lima you must be the most patient person on the planet.Months with no lathe, OMG.

Can I assume that you hit the run button, and nothing happened. Are the leds on, does the screen have any codes showing. If not there is no power, If yes let us know, what you see. Do not expect anyone to be able to help you much without information from you.

Did the electrician turn the lathe on,
Is the breaker on
Is there a disconnect switch on the machine, on?
did he use any of the existing wiring on the lathe, or all is new,
What did he say before you wrote the check,

thats a beginning.

You need to read chapter 2 of the manual.
The default setting for the run command source is the keypad unless someone messed with the settings. This is located under the “A” Group: Standard Functions, as A002, read in the manual how to change these functions. But A002 is the run command source, 02 should be the data, which is 'run key on keypad'.
Then A001 should be set to 02, which is it's default of 'function F001 setting'. You need to then goto the F001 command and change this from 0.0Hz to what you think is a safe Hz setting. You can set this up to the A004 ''max freq. setting' which is default at 60Hz.
Once you have set the A001 to keypad, and F001 to the motor run Hz (I would use 60.0), then you can press the keypad run key.

I believe this drive is 15HP and requires 3PH input to operate, I don't know if this model works on single phase, but your implying it's in your garage.

The lathe looks like a 14x40 with a 5HP motor.

Stupid question - does this VFD have a run/enable digital input, and if so, does it need to be jumpered in order for it to go? I've no experience with that particular VFD but every other one I've seen won't run unless there's a jumper on the enable contacts.

Thanks guys. I was not only patient but broke so I had no choice but to wait months. The VFD is powered up. The display is lit up. I pressed "Run" and nothing happened. The electrician wired the VFD direct to the motor, but he used the wires coming from the motor and spliced them to the wires from the VFD, bypassing all the old relays and such. He left saying "We'll all the high voltage stuff is connected so that's it..." He left it to me to figure out the rest. He's sending me a bill in the mail. The folks at the Drives Warehouse said the WJ200-110LF will take either three or single phase power.
Ignator, I'll try setting the Hz to 60 and see what happens. I'll get back to you guys....

I'm back. I set the Hz to 60 and I think I enabled the keypad correctly. The fans on the drive kicked on but not the lathe. When I press "run" the "run" LED comes on but the lathe does not. Prior to buying I verified this was the VFD I needed.

What type of businesses deal with installing and programming these things? I paid $700.00 for the drive and will have to pay the electrician almost $400.00. At this point I'm so annoyed I'm willing to pay someone to do it for me. The manual makes less sense every time I read it.

That drives does require 3ph input. Are you sure you have that?

Lima9 · Aug 15, 2014

The folks a Drives Warehouse said I could use this model. It will take single or 3 phase. The manual also shows a diagram for single phase input. What kind of "electrical / computer specialist" do I have to hunt down to make this work? Anyone?

jakefreese · Aug 15, 2014

OK, what does the display on the drive say when you hit run?

Does the run light come on?

You need a person familiar with variable speed AC drives, preferably with experience with your particular brand of drive. You could try offering beer money on CL to someone who has an industrial electrical background or experience and see where that gets you (I'd do that sort of thing but Iowa is a long drive from LA), but posting here what it says on the display when you hit "run" will help us diagnose it for you.

Another thought I had was that if it says "REM" anywhere on the screen it means its expecting a remote input, somewhere on the DI/low voltage lines. You may need to change parameters to enable local control.

I have a hitachi wj200-150LF I'm garage. I confirm that it has been hooked up to single phase inlet power the about 3 years and drives a 3phase 7.5 hp motor well.

When the vfd is powered up, display shows 0.00 hz, and little square green led indicates power. When I push green run button, the green run led illuminates and the red number display spools up to my preset frequency. I've set it to 60.0 hz.

If your vfd behaves something like that and your lathe motor does not turn, I can think of a few items to check.

1). Confirm, visually, that there are indeed no switches, contactors or any other circuit interrupt between vfd and motor. If you have something, you will need to make sure circuit is closed before hitting vfd run.

2). Confirm electrical output from vfd to motor. Safely use voltmeter to measure voltage at motor. I'm qualified enough to know when I'm over my head in electrical matters and definitely not qualified to tell you how to do this safely over a forum post.

3). This vfd was significantly less intuitive to set up compared to my other vfd. The folks who earlier described the various settings are correct. You need to set about a dozen or so settings via the number pad and the arcane menu. It can be done if you just accept sitting with the little hitachi book and reading through the menu settings for a couple of hours.

Good luck with it.

With power on to the VFD the display reads "0.00" and the green "Hz" LED is on. When I press the green "RUN" button the display reads "0.60" and the "RUN" LED lights up. That's it. I don't have a volt meter and honestly don't know how to use one. I should have paid attention to my dad when he explained it years ago.
When I set the display to "Output Current Monitor" the green "A" (indicating the reading is current related) and the display is reading .0 through .5 over and over.

When you push run and turn the dial, can you make it go over .6 hz?

I'm thinking you programmed the F001 parameter to be 0.60 Hz, and that's too slow to start the drive up.
They do give some examples in the manual on set up.
I found that this manual has multiple drives contained in it, and the single phase they show is L1 and N, this is not US power but Europe with 240V single phase to neutral. However, if it is expecting 3PH, then you would get an error on the LCD display.

Check through the parameters again. As it is new, all the defaults should be per the manual.

I'll read through and see what else may need to be changed. But verify F001 is 60.00.

Matt2016 · Aug 15, 2014

Sounds like you just need to set th output frequency to 60.0 hz. This vfd requires the output frequency to be input through the keypad--there is no potentiostat style knob on this vfd. Navigate to function A004, I bet is reads 0.60 hz. That means that your vfd maximum output frequency is 0.6 hz, and your motor will spin 1/100th it's nominal rate. Set function A004 to at least 60.0 hz. That function is the maximum output frequency. You will also want to confirm that your F functions are set to sensible values. F functions define the rates of acceleration, deceleration, initial rpm etc.

Go to the instruction manual, collect your patience and read through all the function definitions (they will indicate normal parameter values). Read how to change and set parameter values. You will get it figured out over the course of the day.

F001 is set at 00.00. Pushing the up arrow does nothing. It's locked at zero. "b031" according to the manual needs to be set at 10 for high level access. However the display jumps from "b011" to "b037" after pushing the up arrow. Nothing in between. Holding the up and down arrows simultaneously causes the individual characters to flash and you can manually input b031 but it won't stop flashing and the setting can't be changed or imputed. Once you get the digit to stop flashing it goes back to b011 or one of the other settings (none of the ones I need).
Looking for my sons baseball bat. Gonna smash this thing to bits.

Did you hit stop before attempting to edit the B031 parameter? Unless access level is already set to 10 you can't do a running edit on B031 according to page 3-53 here http://www.clrwtr.com/PDF/Hitachi/Hitachi-WJ200-User-Manual.pdf

Lima9 · Aug 15, 2014

Yes I tried it both in run and off mode. I can't directly select b031. Pushing the up arrow it jumps from b011 to b037. I can get the individual digits to flash and input b031 but with a flashing digit I can't change the b031 settings. It does nothing. Once the digit stops flashing I'm back to square one.

Had to check an old thread, something about parameter B008 needs to be set to 00 to disable the phase loss detection. You might give that a try. Have as yet to get mine running but someone had suggested that to me in order to try mine out on single phase.

Those vfd's are built to run on three phase only, however, by going bigger than the horsepower that you have (which is what you have done), its my understanding that you can indeed run them on single phase. The default however, will still be three phase, so it may just need to be programmed that single phase is acceptable.

The parameter given above was for a Hitachi sj300, not sure if it will be the same for yours, but I think it should point you in the right direction. You should be able to find something about cancelling the phase loss detection. Somewhere I read something from Hitachi (not in the original manual) that told how to go about using their vfd's on single phase, you may be able to google it.
