VFD Spindle Control via OpenBuilds BlackBox Controller and Software

Well Ok, I can see that having separate commands could be useful. I Was using the same IOT relay for the router and Vacuum before.

 

hey guys i have a hengyang hy02d223b openbuilds black box controller. setup i'm not getting variable speed just on off spindel runs on max any help

 

Done all settings as per video and set up just get max do I need to change the jumpers in the bb

 

So got variable speed but only 9000rpm any suggestion

 

Thanks I got it changed from 4 to 2 and 24000 rpm thank for your help

 

I've got this exact spindle and followed the instructions precisely. I'm not seeing what to set the minimum frequency/RPM to. It looks like 'PD011 Frequency Lower Limit' is what I'm after but it's defaulted to 0 which doesn't sound right.

 

I changed it and it's working correctly, however it won't turn off with M5. Is this the jumper in the BB that I need to change?
Also, will I still be able to use the IOT relay for vacuum?
Referring to my other thread if Fusion sees the min RPM at 10k and CAM is set to 6k will it still post correctly even though it throws the error message?

I appreciate your help, Peter.

 

Realizing this is an older post, I would like to try and get clarification on the voltage output on the blackbox. I have a VFD and spindle on order.

So, if I send a spindle speed of 20,000 rpm on the M3S20000 line, the BlackBox will automatically translate that to the appropriate 0-10v output needed to tell the VFD to drive the spindle at 20k rpm, right? All this assuming I have my $30 and $31 values set to 0 and 24000, which is the max for that particular spindle.

Thank you in advance for your assistance!

 

I went back and re-read the documentation. According to that, I have to know what voltage will operate the spindle at 20k or 18k or whatever, and send that on a scale of 0-1000. I thought the purpose was to send the spindle rpm and grbl would convert the 18k or 20k or whatever to say, 800 or whatever voltage would be required to get the spindle to spin at 18k. According to how I am understanding the documentation, I have to calculate what voltage 18k rpm would be equal to on a scale of 0-1000, 1000 representing 24k, and send that as the spindle rpm in VCarve. Am I totally misunderstanding this?

Also, the 0-10v document refers to the github for grbl, which proceeds to discuss pwm rather than voltage. Should I have ordered a VFD that supported pwm instead of voltage?

Sorry to be so dense, but I am thoroughly confused, and am just trying to keep from blowing up my motion controller or vfd.

 

Okay. I went back and re-read the grbl statement. I think it makes more sense now. I'll definitely use a vom to check voltages before I hook up my vfd to make sure I get the correct voltages out.

Thank you!

 

I just completed my build with the same hardware as Josh. When I start my spindle it moves up to 24,000 as expected. I checked the voltage coming from the Blackbox and it’s 9.87v, so that checked out. When I change the speed through grbl to 8,000, I can hear the spindle slowing. But it only slows to 16,000. The voltage coming in on V1 is 3.2 volts. Changing the speed to 12,000 in grbl causes the spindle to go up to 24,000 with a voltage of just under 5v.
I’ve checked the wiring and the settings multiple times and all looks good. The voltage coming in is at the level it should be but the rpm’s are always double what is expected. With a max of 24,000.
Anyone have any thoughts?

 

I’ll recheck everything and take a look at the poles; I had not checked that setting. Thanks

 

Okay, I checked everything and finally realized that PD70 on the VFD was defaulting to 1 and wouldn't let me set it to 0. Having it at 1 meant it was expecting 0-5v which is why all my speeds were being doubled. I reset all the settings on the VFD and was finally able to get option 70 to change to 0 and stay there. All is working fine now. Thanks for the assistance.

 

Thanks for sharing this. I followed this procedure for my BlackBox X32 and (same) Huanyang VFD. Overall, working just fine.

One minor caveat.... probably something that can be tuned if I care that much about it... This may even be due to some prior programming I had in place on the VFD for RS485. The scale does not appear to be linear and I'm pretty sure it's in the VFD rather than the BlackBox. The curve is wider at the bottom and tighter up top so I tuned the controller to match 16,000 RPM where I normally run and will live with the +/- 1000 scaled RPM variance at the extremes above and below it.

I do miss RS485 but this will work just fine!

 

We just had to change our blackbox out and the new replacement is the X32. All was good until testing after setting the proper voltage. The spindle turns on and I am able to adjust the speed properly but when I turn off the spindle it only drops down to 196 rpm. is there any additional setting or connections needed to control the shut down of the spindle? Oh and just to be on the same page we have the exact same spindle and VFD that has been working great and I even swapped out the original black box from another machine to verify it was the fault.

Hi Tony,
Same thing here, I get a Huanyang VFD that still indicates freq=24.40Hz for a M5 / STOP command.
Have you found the parameter(s) and value(s) to set up ?
TIA

 

I have gone over all the setting regarding signal for spindle and still no joy. I switch the X32 over to the older 4x box and everything works just fine, spindle shuts don and starts perfectly. When I then switch back over to the X32 box everything works EXCEPT the shut down, it hovers around 196 rpms. Our spindle and VFD is the same model as in the video in post#1.
I have gone over all the setting in the VFD numerous times without a change.
The only differences are the black box versions. The X32 has numerous additional settings that are not in 4x firmware and I tried all different setting related to the spindle with no success. As a side note I am also running the latest version of OpenBuilds Control.

After several hours of trying to get this running we are at the point of returning these X32 boxes we ordered and replacing them with the older 4x that is known to work.
