Programming Huanyang VFD for 2.2kw Spindle

[safeairone]

What is the max current for the spindle?

Without looking at the VFD manual, I imagine PD142 is the point after which it’ll throw the overcurrent code.

The specs for the 220v 2.2kw spindle is 9 amps. Mathematically, I’d imagine that a 110v spindle would be higher than that (like, double…but verify this). You’ll need to find out your spindle’s current (as in “amps”) specs and adjust your PD142 accordingly.

I found a spec from the seller saying 15A, should I turn my 9 up to 15?

I'm going to take a guess and say they forgot that it was a 110v when they wrote the PD142 setting.

** update **

VFD wont let PD142 go over 11. Still will not run with that HOWEVER, its a new error.

EOCA (overcurrent error during ramp up)

I think the only settings I changed from the factory default settings in that post where I showed all the settings, were the just the ones listed. All the rest were factory default settings.

Welp. Something at some point went south then on my end. I think I've gone through all those settings ten times now, I think I might be able to do it without looking. I'll put those settings back into it again, keep it on manual mode, and see what results that gives.

FIXED

Here are the current setting and the order (I believe this to be important) I set them up in:

PDXXX: Value
013: 08 (resets back to default parameters, only do this once)

005: 400
004: 400
003: 400
141: 110
000: 0
001: 1
002: 1
006: 2.5
007: 0.5
008: 110
009: 15
010: 8
011: 0 (100 also worked)
014: 10
015: 10
025: 0
026: 0
041: 13
070: 0
072: 400
073: 0
142: 9
143: 2
144: 3000

The high torque settings recommended in the other thread did not work, the constant current however did see the below changes.
PD006: 20
PD007: 4

1) How quick can quick can I accelerate the spindle safely (PD014)? is 6 seconds pushing it?

2) Can I fine tune PD141 to match my MASSO speed exactly? I forget at what RPM value, but it gets worse as the speed goes up, upwards of 1krpm... off of the setpoint.

3) Any idea where can I find a torque chart for my spindle? in the manual is 220v and 380v spindles/VFDs... I'll start to search the web.

Thanks you guys for all of your help this far!!!

You can decrease the acceleration time till you start to trip error codes on the VFD. If you use small tools (end mills), you can decrease a lot more than if you use a high-mass tool like a surfacing tool or shell/shoulder mill, which will take a lot more “oomph” to start turning while trying to meet the acceleration time you programmed. I found this out the first time I mounted my heavy shoulder mill and tripped an error code after weeks of running end mills with no problems.

I’ve found that the RPM on the VFD display is always off by a varying amount from the commanded RPM and, if I remember correctly, differs by more at the upper end of the RPM band than the lower. I solved this problem by not looking at the VFD display anymore, since a few hundred revs doesn’t make a whole lot of difference in the overall scheme of things.

Not sure about your spindle’s torque curves, other than a google search.

Incidentally, I’m curious about your first setting—PD013. You set it to 8? Is this right? PD013 should be 0 to keep the settings and 1 to reset all settings to the factory default. I don’t think an “8” is an option.

Glad to hear everything is working for you!

Also, note that the reason I set PD011 to 100 was to make sure the water-cooled spindle has a minimum RPM of 6000, even if I command less than 6000 RPM in my G code.

The reason for this was that I read in several places that below 6000 RPM, whatever electrical magic that makes these water-cooled 2.2kw spindles spin, can start to heat up the spindle internally and could result in damage.

I have a 24k rpm 2.2kw 110v water-cooled spindle and appropriate VFD for it (2.2kw 110v).

Up until now, I ran the spindle solely from the VFD it's self but I couldn't spin under 9k (we used to have the same model at work that I could run slightly above 1k rpm so I'm thinking I've had something wrong from the get-go). Regardless, I got tired of running the risk of spinning a tool too fast/slow based on what my programs called for, I have a tendency to forget to change rpm speed in between tool changes. I have since then went through and wired everything in to run it from the MASSO G3.

If the spindle is set to a very low speed, 10k rpm and I set my rpm override to say 10%... I can slowly work my way up to the required spindle speed. 100% speed however is NOT what I set it to be with Sxxxxx on the MDI. 100% is the full 24k rpm of the spindle. Regardless if I set the rpm to anything over 12k my spindle starts to speed up and throws a E.O.C.n on the VFD and shuts down. This code in the manual is a "over current at constant speed" error. However the spindle worked prior to this fun little road trip I'm on.

Read through some other forums I could find and didn't see anything that would help my case, maybe I missed something important here...

Any help is appreciated!!

Current VFD settings:

I got these from the seller... only changed PD001 for MASSO control.

I DID move that jumper in the VFD between the three pins from the right two to the left two pins.

Would any of these settings change if its 1.5kw 220v 8a 400Hz spindle
Thanks Greg

Yes, I know that 008 was max voltage. So if nothing else changes, that one would.

I would grab the manual and buzz down through the parameters I changed to make sure that they at least make sense for your spindle. I believe I found a copy online somewhere but don't have it anymore. I have an actual book somewhere though if you can't find it online.

Look at 144? 141? maybe some others...

I actually toasted my spindle since this thread was active last but I did get my spindle running well before meeting its maker. I now am moving on to a 3.5kw ATC!! They sent me an already tuned VFD haha.
