Hitachi WJ200 Settings Help

[BanduraMaker]

Howdy,

So I just got a WJ200 inverter and have it up and running. I'm controlling it with Mach 3 and a Gecko G540 0~10v output going into port [O] on the VFD

So far, everything is working O.K. and I'm able to control the speed of the spindle but I have a couple of minor issues.

I don't have a control relay and would like to shut off the spindle just using the control voltage. Looking at the parameter list, it looks like A011 ~ A015 should allow me to create a dead band (e.g. anything under 1v = 0Hz) but for some reason, I'm not able to access these parameters!

When the display is showing A005 and I push the up arrow, it goes directly to A020, not allowing me to edit A011 ~ A015.

Anybody have any ideas what's going on? I imagine the parameters are locked out because of a setting somewhere else but I can't find any info on it.

TIA!!!!

A little more info I forgot to mention -

When I turn off the spindle using Mach 3, the spindle does indeed stop but the VFD is still outputting almost an amp (.9 I think) at a frequency of a couple Hz. I can hear a little buzzing in the motor too even though it's not moving. That's why I'd like it to output 0Hz, 0A

[BanduraMaker]

Using the PC software and USB connection, I was able to change those parameters and have it set up to send 0Hz, 0A at anything under 1v and it seems to be working.

The one mild rub is that currently I need to use a front panel switch at the start of the session. Hopefully I won't forget!

For future reference, if anyone knows why those parameters were locked out of the front panel, would be interesting to have it documented.

u r too fast!

Hmmm very strange.... I used prodrive to change b031 to high level (10) and b037 to full display and it still doesn't show up on the front panel.

I'm also having that trouble the other guy had that anything I set using prodrive isn't stored and is lost at power down.

Any thoughts?

[BanduraMaker]

More info:

Changing B037 from the front panel gets you access to all of the parameters. Still having issues having it remember after power down though.

I guess I'll call tech support tomorrow.

[mike_Kilroy]

after you change a parameter from the keypad, you push SET while the new value is blinking at you? that should save it to eeprom for use after power down...and after pressing SET display should stop blinking the new value and go back to the parameter number that was just saved - like B083 in the attached sample pix....

I would then press SET once again to see if the new value I entered took or not. If it did, it will be there and it will no longer be blinking. This tells you it saved to eeprom and you should be all - dare i say it - SET! sorry 'bout that, couldn't resist

Thanks. I was stuck with wj200 parameters visibility and now I know how to make them visible.

I did the power test and am able to run the spindle from vfd. I followed the manual and set both A001 and A002 to 2 (control panel input), A003 to 60hz and A004 to 300hz (spindle base and max frequency).

I am getting 10V at BOB and I think my wiring is correct (thanks to Kelly from another thread).

I will make my parameters visible now based on info here. I think I need to set A001 to 1 for analog input. What other parameters do I need to set? Do I need to do any kind of reset after power test to control spindle/vfd from Mach3?

I am new to cnc and vfd and will appreciate any help you can provide.

Thanks

The attached Jpeg has I think the main settings you need to get it working. I'm using a G540 with Mach 3 and use the 0~10v control signal and one of the output pins to run forward, I don't have reverse wired up at all.

On A13, I have it set at 10% to give a little bit of a buffer from when I didn't have a run enable wire and was setting it to start by hand. That could probably be set to zero now that I have an enable wired in.

It's very important to hook up a proper ground between the VFD and the G540 to get the control signals to work correctly. DAMHIKT.

I am using DMM BOB and I also have 10V output. When you have time can you answer few more questions

1) a201, a202 etc. do i need to worry about them when i do not have second motor?
2) not sure if i need reverse wire from dmm, will find out soon. i think control from pin 16 should send the command to vfd
3)you are setting a003 to 300, guess this is your motors frequency, i thought a003 is for inupt a/c freq which should be 60. spindle freq is set in a004, am i wrong?

since i got stuck yesterday, i had to open the manual and saw h001 function and i also remember Al mentioning it in another thread (means i should pay attention to this one). did you get chance to play with it.

let me go to basement and see if my findings from you posts get me going.

thanks again Andy.

I think not.

I think you only need reverse wired in if you plan on running the spindle in reverse. At the moment I'm not so I didn't wire it in.

3)you are setting a003 to 300, guess this is your motors frequency, i thought a003 is for inupt a/c freq which should be 60. spindle freq is set in a004, am i wrong?

Base frequency is the motor base frequency, not the input frequency. I don't remember where I got the info, but I was told to enter the spindle's maximum rated frequency there. a004 sets the spindles maximum frequency in practice. i.e. a003 is the rated max, a004 is the max that YOU want it to go to. (and yes, 300 is the max freq of my spindle)

since i got stuck yesterday, i had to open the manual and saw h001 function and i also remember Al mentioning it in another thread (means i should pay attention to this one). did you get chance to play with it.

I have not. I was intrigued by that post as well and I found somewhere on the hitachi site that you don't need to use auto tune with standard induction motors. Everything is working pretty well right now so I'm not too keen on messing with it!

[Al_The_Man]

The auto tune is a good way to get the basic ideal tuning, as long as you have entered the correct pole count and base freq etc.
If you don't like it you can reset back to the default parameters by using the Reset to default.
There is free PC software on the Hitachi site for programming and for monitoring while running through the USB port.
