Spindle Speed Settings only from file, no MDI possible?

Hello Community,
many things are working nowadays with  Linuxcnc 2.9.2 with Probe Basic on a MESA 7i76e. But:

A few weeks ago I had to change my Hitachi VFD because it had no 10V output for spindle supply from the beginning. I sent it to service in April and I had to get the 10V from a separated power supply, this worked fine with a chinese VFD for the time the Hitachi VFD was in service.
Last week the Hitachi came back from service, the 10V Out was working, but surprisingly I cannot make MDI speed commands any more. I set S6000 or S12000, press Enter, in the spindle display on the right side 22000 occurs and I can press FWD Button but nothing happens.
IN the HALSHOW there is
0 at spindle-out
0 at spindle.0.speed.out
0 at spindle.0.on
0 at spindle.0.forward. Tested with S6000, S12000 S24000.

All this worked fine with the chinese VFD before.
So, I thought my 7i76e card is burnt up (I did not change any of my HAL or INI files since I sent my Hitachi away), but surprisingly further experiments could deny that.
Speed instructions from a file are working as they should. E.g. my warmup file - spindle turns in the right direction, right speed, right display down right.
Parameters are the same in the Hitachi as before.

Do you have any idea what could have happened here? I'm totally clueless...
Thanks for any hint and help!

Does the Chinese VFD still work?

Is there any downside to it compared to the Hitachi?

AFAIK, Hitachi has not made elctronics for a long time.

How old is this thing?

Hi langdons,
yes the chinese has only 1,5kW instead of 2,2, just 320 Hz, no vector, no safety settings and outputs, no rs232 programming, it's cost is only 1/4 of the Hitachi. It is 3 years old, mostly layd in stock, has had 7 hours this year since built in, mostly parametring and testing time, but the 10V problem was from the beginning and sucked. Hitachi made a costless repair on it. I think, there's nothing wrong with the VFD itself, but sth has changed in Linuxcnc. But where?
(Hitachi is founded in 1910 and in the US since 1959, Hitachi VFD's are very common here in Europe and I have no doubt about their quality)
 

Hitachi excavators are best-in-class.

I've seen smallish, 30-year-old excavators being used for pretty big projects here in Canada.

Not flashy tho, old school.
(Tried and true)

I assume their electronics are just as good and reliable, though Hitachi actually split into many different companies a while back.

I would probably recommend just buying a small, inexpensive 12V delta (or) power supply and adjusting the voltage to 10V and not messing with stuff.

People sometimes die in surgery, VFDs might sometimes die in surgery too.

Whatever, you can't change the past.

What is the model?

Could you link to the datasheet of the VFD?

(Don't attach files unlesss you need to, LinuxCNC does not have the money or server infrastructure to store lots of files)

www.hitachi-iesa.com/sites/default/files...struction_NT325X.pdf Its a WJ200-022SE

Well, I had such an external 10v source before. It worked with both Hitachi and Chinese VFD. The voltage now is correct too, if LCNC gives it out to the Inverter.

What I want to mention again - just my opinion - the error seems to be in Linuxcnc - FWD and Speed signals are not sent out from LCNC just in MDI/Manual mode. My logic says - if the VFD works fine out of a file, what could be a failure in the inverter? I think theres sth wrong in the outputs of LCNC/Probe Basic. Maybe I'm wrong.

I'd trust your judgement.

It's amazing how often intuition is spot-on.

Maybe try making a new quick-and-dirty config?

When my CNC wasn't working quite right, I made a new, identical config with stepconf.

It fixed it.

So you are saying that if you enter:

s12000 m3

 (in the MDI tab)

That spindle.0.on remains false?
 

Thanks langdons, that would be the last step if others fails. There are a lot of things i would have to setup again, such as wireless Handwheel, Probe basic, the TooTall18T probing routine and others that work fine at the moment, so I am a little afraid that i get more problems as today. I'm not a coder and not very familiar with all that stuff.

Thanks PCW, I will try that tomorrow and give you feedback.
This file works and let the spindle turn:
M03 S6000 G04 P120
S12000 G04 P120
S18000 G04 P120
S22000 G04 P120
M05
M30

Kind regards!

What I meant of course was

s12000 m3
