Hi guys,

I just purchased my first VFD, a Hitachi WJ200. Is anyone familiar with the setup of this driver with the DMM breakout board and Mach3?

I am not sure how to get started so any help would be great.

I don't have any experience with the WJ200 but I have been looking at one for a few reasons.
The reason for the post is I wondered if you had seen the free set up software that you can carry out with a PC and USB port for this VFD, including monitoring in real time?
I would also imagine you could control it through Modbus, according to a previous post here for a VFD control this way, it seems that all you need to write is a couple of macro's?

Thanks Al I will read that thread you posted... I have not downloaded the software yet but plan to and yes it will do Modbus but I have never worked with that so I am a bit lost.

[Al_The_Man]

I plan to look into it a bit further, but here is a previous post that explains some of it.

I found this image on the Mach forums.

I also found a .brn file that I downloaded but cant upload that here.


My first problem is a cable? Can I simply make one or do I need something special to go from Com1 9pin to the Hitachi? It has both a USB and a Rs-485.

[Al_The_Man]

I believe the USB is for monitoring and the RS485 is for Modbus, you need a RS232 to RS-485 convertor, they are quite plentifull and cheap.

Do you have a link?

Here is the link:
WJ200 low and high range hex frequency data

I posted and one guy replied with a link to a converter but it is $143 or something, he said the cheap ebay one would not work?

Really don't want to spend that kind of money for a simple conversion.

Do you have a link?

You can run the VFD straight from the DMM Breakout Board this is quite easy to set up
you don't need to buy anything but some shielded wire, & you most likely already have that, you can use an old computer cable

[Al_The_Man]

The Modbus saves on outputs for PWM & M3/M4.
I think if you check around some of the conversion posts, the convertor that works can be had for alot less.

Thank you Mactec I will read that over.

Al, What do you mean "The Modbus saves on outputs for PWM & M3/M4." ??

[Al_The_Man]

If you do not use the Modbus, then you have to use the P.P. pins I/O for the M3/M4/M5 PWM signals.
The Modbus frees up these pins.

OK I got this half way working with the breakout board. The spindle starts and stops on command but so far I can not change the speed.

On the AV_OUT I am reading -0.12 volts when the spindle is on and -0.06 volts when the spindle is off. If I understand this correctly I should be getting variable positive voltage from 0 to 10 volts depending on the speed Mach is calling for?

Here is how I have it wired:

AV_OUT
+v wired to H on the VFD
Aout wired to O on the VFD
G wired to L (lower row - analog ground) on the VFD

D_out 16
D16 wired to #1 on the VFD
S16 wired to L (upper row - digital ground) on the VFD

Setting in Mach3 per the document provided a few posts back except I had
to set output 1 to ACTIVE LOW.

Any ideas?

Here is a post that Woffler did with his drive set up he is using the same drive,Mach settings can be different from those in the PDF, That is just a guide

Thanks guys,
Not sure what I did but I got it working a few minutes ago.

The reference voltage from the VFD is 10 volts. I was not getting any voltage from Aout on the BOB. I then went into Mach and changed the active low setting on the spindle in "ports and pins" "motor control" that jumped the volts to 10 on Aout... then I set it back and it started working??

My wiring was correct the whole time.

Now I have to fine tune the speed settings but that should be easy!

Al,
I ordered one of the 3.00 Ebay adapters after reading another post on the Hitachi that worked fine with Modbus so I will play with that in the future.

Kelly,

I got vfd today. When you get the chance, please post wiring picture and list of vfd parameter you set. You thread will save me lot of time and headache.

Thanks

Mectec54,
You mentioned shielded wire. I see few here igus® - Chainflex® Continuous-Flex Cable
do you know which one I will need. Do I need any tool to work with shielded wire? Do I need shielded wire both on vfd input and output side? VFD will be about 25 feet away from 220V outlet and my current table is 110 inch long, so VFD will be about 15-20 away from spindle (working on changing the size of table but this is work in progress).
I did buy good electric wire in large quantity thinking that I will need it from 220v outlet to vfd but if shielded wire is required, so be it, Of course my preference will be to use the wire I have. I don't know much in this area and will follow the advice I get here.

I think I can fit vfd in my current control box with some adjustment. Is it advisable or should I ask is it worth the effort to put vfd in my control box with dmm drivers, power supply and BOB?

Thanks

Here are the pictures of the wiring.

B031 - 03 or 10
A001 - 01 Freq source = My manual has a misprint. Think it is 01
A002 - 02 Run source
A076 - 01 PV source

Other settings to look at

A003 - 40 hz
A004 - 140 hz
A061 - 140 hz
A062 - 40 hz
F002 - 3 sec.

In mach3 to calibrate the spindle speed I ended up just playing with the min and max rpm numbers until
things are close. I ended up with a MIN RPM at 300 and MAX RPM at 11,000.

This made the VFD run at 60hz with a s3000 command in Mach. My pulley ratio is
1:2 so motor is at 1500 RPM (rated speed at 60hz) and spindle at 3000 RPM at 60hz.

If I tell Mach3 to go to to 6000 RPM with a s6000 command the VFD goes to 120 hz.

I hope that helps.

Kelly,
Very helpful and time saver. Just one more question, are these wires going between BOB and VFD are stranded wires? If no, what type of wire are they (when I go in home depot, what should I ask for)

Thanks

Who said expensive USB?

I used both at different times... I just rewired everything to clean it up and just grabbed some wire from my wire bin. Solid or stranded will work, 18 to 22 gauge. Your only passing signals and 10 volts at a 50 ma or so.

Look for thermostat wire, that should work fine. I think even cat5 will work.
