Did you ever figure this out? I am getting a constant e30.3 error on my hitachi wj200-022SF. And it is driving me crazy!!! Please help!
Thanks
Bob

How do you have it wired??

Do you have a Single Phase Drive or a 3 Phase Drive?? I guess it is single Phase by the part / model number

Do you live in NA or some other country??

What is your input Voltage??

Post a Photo of the input wiring

Single phase input, it's the wj200-022sf. I'm in North America. Running the VFD from my 240v dryer oultet, it's a 30amp breaker. 10 gauage wire all the way to the VFD.

I'm at work and the VFD is at home... So I can post a pick later tonight. I have the power running to the L1 and N terminals. They are reading 244volts together and separately to ground they read 122volts.

Then I have 4 wire-12 gauge shielded wire running to the 2.2kw, 8.5amp,400hz water cooled spindle.pons 1,2 and 3 are connected to u,v and w. The spindle ground is not connected to the VFD in anyway.

When I run the VFD with no spindle, it works fine. When I hook up the spindle I get an E30.3 error immediately. I hear a quite click, and then nothing. E30 means Driver error, Excessive electrical noise may be
the cause. (So says the Manual). The next nu,mber tells me the Inverter status at trip point, .3, which means constant speed.
When I run through the trip history, d081, I get:
Output frequency: this I can't remember exactly what it said... I was controlling the frequency via the front panel, I can look when I get home. I wanna say it was a low frequency...
Output current: was somewhere in the 2 Amp range
DC bus voltage: 384 volts, Normally the dc bus voltage in a VFD is 1.414 times the ac RMS line voltage. So I thought it would of been closer to 340ish....
Elapsed RUN time: 0.5 seconds, or less ( I tried it a couple million times)
Elapsed power-ON time: something like a couple seconds, 10 or 12.

Here is my parameters:
A001- 02
A002 – 02
A004- 400HZ
A003 – 400Hz is Spindle base frequency
A061 – 400HZ
A062 – 0
A082 – 220 Volt (that's what the spindle has etched on it.
B012 – 8.5 Amps
H003 – 2.2 KW
H004 - 2 poles


Thanks for your response and willingness to help.

You need to have the spindle Grounding connected, you said you have a 4 wire shielded cable this is just as important to be connected correctly as the input cable, you need to check the Pin 4 of the spindle to see that it is connected, if it is not then it has to be corrected, the spindle Ground does not have to be connected to the VFD But all Grounds must terminate at the same place, ( called a Star Ground Point ) it is sometimes easier to connect the Spindle Ground to the same Ground Point as the VFD, Shields have to be Direct Grounded at there Termination

12 Gauge is way to big, how can you fit that in the standard spindle plug 16 Gauge is more than enough for this size spindle

All my steppers and drivers are grounded (star ground point) they are 110v. Can I ground the 220v to that as well. I am a Mechanical Engineer, not an electrical. :-) I only took one electrical class in college. And barely passed.
I guess that would make sense, e30 means too much noise... I will verify my shield is direct grounded too.
Thanks a lot!!! I will try some more tonight.

Have you just one power input supplying your machine, 240v ( 2 Hot a Neutral and Ground ) and split for 120v (1 Hot Neutral and Ground ) for the stepper supply

Or do you have 2 independent supplies a 120v supply and a 240v supply, doing it this way can cause a Ground loop, which you don't want to have

2 independent supplies. So I should probably ground them independently.
I has some new speakon cable laying around. Hence the 12 gauge. It fit.

You should only use one incoming Ground wire, or you will have a Ground loop problem, so both the 120v and the 220v will use the same input Ground wire, This may be what your problem is

As long as the cable is rated for high flex or it won't last very long, any thing will work, this is the main problem that cables don't have the flex that is needed for these machines

its a hitachi wj200 it has been working fine with a 24000 rpm chinese 2.2kw spindle . then the error came up . as said i plug everything apart from power in and it still has the error code

You will have to clear the fault, follow the manual on how to do this,\

To get this fault, you may not have set the correct Parameters in the VFD that suit your spindle, this is the normal cause of problems like this, wiring also can cause this problem

Have you checked the spindle Ground / Earth connection, Pin #4 has to be connected to the spindle most are not and need to be corrected

[steve78]

i find i have the same problem..i have disconnected every cable apart from the 240v input and it still comes up with e30.1 does this mean the vfd is toast or maybe the rfi filter thats inline just before it

any help appreciated

What is the VFD you have, I guess it is the same as in this post, then check how you have it wired, in the UK you would have, ( 1 Hot ) Neutral and Ground / Earth connected, this is different from the USA, which is what the first post is about
