The braking does work but not as I expected it to.
 
I have a Danfoss VFD on my Bridgeport and with the brake resistor enabled it improves the deceleration considerably from the moment it starts slowing down.

With the brake resistor enabled on the Huanyang and the deceleration time set to the minimum 0.1sec (calculated from 50Hz I think) the slow down rate is not a whole lot different to NOT having it enabled.
The resistor is not used to dump energy until the bus voltage exceeds the max of about 375VDC (don't quote me on that but it's close) which is in the last 10% or so of wind down.
The deceleration time from 24000 rpm (400hz) with a 6mm end mill in the collet is around 5 seconds. Nothing like the setting of 0.8 seconds that the setting implies.  ::)

So with the deceleration set to 0.1sec and the resistor NOT plugged in, the VFD lets go of the spindle (coast stop) when the bus voltage gets too high in that last 10%.
With the resistor plugged in you do get an increased deceleration over normal but only in that last 10% and only till the bus voltage drops below the maximum again.

In summary,
I think that my 2.2kw high speed spindle does not have enough inertia to make any use of the breaking function with an external resistor attached.
You can reduce the deceleration time and get some improvement of deceleration without a resistor. If you drop it too much and the bus voltage goes too high the VFD will just disconnect from the spindle until the bus voltage drops again. (as it should)

If I used the Huanyang on the Bridgeport with it's increased inertia it may work as expected, but that is 380V 3 phase and the Huanyang is only 240V rated.

Cheers,
Phil


Hi.

Good work w/ the implementing of the breaking resistor!!

So you mean that I could set my deceleration time to the lowest (0.1) even w/o the resistor and the VFD will be ok w/ it? I don't know what I use today but stop time from 24000rpm is like 12 sec or more.

Any one know what would be a safe acceleration time for the Huanyang VFD w/ 2.2 kw water cooled spindle?

Best regards L.

I can't change the DRO in the plugin either. But if I use a screen editor and change the DRO in the RPM field to "1002", IT WORKS!!! So happy!

I don't know much about Mach3 (new user) but afaik the adress for Spindle RPM is 39? I have used the screen editor to look at the # and both the 1024 and machstdmill screens have the same # (39). Is that what I should put in the plugin??

Best regards /L

Thanks Russ.

I get 0 RPM.
Where/how can I check what DRO # to use in the plugin for spindle speed? Maybe there’s another # for the machstdmill screen set?

Best regards L

Hi all.

Any one know how I get the actual RPM to show in MachStdMill add on w/ this plugin? I can't get it to work.

Best regards /L

Hi all.

Great plug in, but I get intermittent errors using it w/ my VFD.

I ger PD001&2 = 2 some times and some times I get 99/2 or 2/99 or even 99/99 w/o doing any thing, just open and closing the plugin settings page. Starting & stopping spindle works sometime but usually not 2 times in a row. I have checked all my wires and reinstalled the RS485 interface but no luck. When I can't stop the spindle I get an E-stop in Mach3 and if I try to open the settings page Mach3 crashes :(
Could my intermittent problems come from the plugin or a bad solder on the RS485 chip (I had to solder a chip in place, my VFD didn't have one)?

EDIT: I use a EMI-filter on AC-line and ferrite cores on the spindle cable.

Best regards L. Kull, Sweden

Thanks for the reply. But is it only the RS-485 interface that is missing it's all good, I'll just solder a chip in place, but if it's not even the same VFD that this plugin is made for it's another story :(

Is there anyway to change settings to accomodate the xin ye Vfds that are being sent out with the spindles now days?

Hi all.

Looking forward to testing the plugin when I have bought my spindle/VFD.

But I'm a little worried that if I order my VFD say in 2-3 month I'll get a different type of VFD that is not compatible w/ this plugin or the Mach3 standard Modbus protocol, see quote above. Is this going to be a problem?

I can't find the seller Linearmotion2008 at eBay.com, does hi go under another name now?

Best price w/ shipping to Sweden for me would be this item:

http://cgi.ebay.com/WATER-COOLE-MOTOR-SPINDLE-2-2KW-AND-MATCHING-INVERTER-/230490523975?pt=LH_DefaultDomain_0

or

Anyone know if it's the right VFD?

Best regards L.
