That's what I did last time
Thanks for your reply. I was not aware. Are you saying that, if I want to use my spindle w/o load to test the drive, it's better to increase the frequency a bit? There is also a current limiter...
I recently found another VFD and I didn't want to spam another thread so I'm posting in this one. It's a Parker 650 series. Just as before I want to test this using my cnc spindle motor, but I have...
How does a low frequency burn a motor? The inverter I got with the spindle motor (as a set) can be set with a pot from 0 to 400hz. I also set the drive for a low current and voltage
I hooked up my spindle motor and configured the VFD with some very conservative settings...and it works! best €4 I ever spend haha. Thanks for all your help
There's no pot to set. When I press "run" nothing happens. I suppose I could connect my 2.2kW chinesium motor and see what happens. The motor is rated to 400hz, the unit can supply up to 120hz. Can I...
Success! I bridged 10 and 11 with a 2k resistor and it does not show the error anymore. I currently don't have a load attached to the unit. When I press start, nothing happens. Is a load required for...
According to the manual "If an external trip feature is not required, this input must be closed (linked to +24V).Provides a dedicated input to trip the Xtravert and immediately disables the output.Do...
I didn't just hit reset. The menu "Y2" allows you to "initialize" the unit, which wipes all settings, resetting it..
I've managed to reinitialize the unit (same as reset) but the fault persists, even with L1 and L3 bridged again
*edit* I've found a reset menu in the manual specifically meant to reset errors -...
Good call! Thanks, I'll look into it.
Would it be safe to try L1 and L3, not connecting L2?
Ok, with L1 and L2 connected, it turns on but I get a F22 fault. According to the manual:
"Fault22 EXT TRIP
DetailExternal Trip; External circuit (Terminal T10) has operated.
Sense level ...
L1 and L3 won't short? Ok, I'll give it a try, thanks.
It's an Xtravert 716. 3 phase 400v input, with an "actual" input of 200-480V
here's the manual. http://www.sigi-elect.si/sites/default/files/doc_tree/Xtravert%20Instruction%20Rev%20E%204201196e.pdf
Thanks for the replies guys. What would be the "correct" way to wire 1 to three phase? Should I just run the 1 phase to L1 and L2 and split the L2 connection to L3, or do I only connect L1 and L2?
I found a VFD in a discarded machine at the scrapyard. I thought it was a 1 to 3 phase inverter but after closer inspection (it was dark!) it turns out it's a 3 to 3 phase VFD. I don't have 3 phase...
Thanks, I'll look into it.
You'd be amazed what expensive stuff I find at the scrapyard that's in mint condition. There's some wear, no doubt but I can't find any damage, backlash, rough bearings...
Reselling was my intention, yes. The reason I was (am) looking for the right type is to get an idea of resale value. The bearing alone is worth 450 euro (new). Selling a used bearing probably isn't...
I'm not saying that it's not a possibility but I don't think it's likely this is custom hardware (except for length maybe). There are 32mm OD, 20mm pitch screws commercially available, just can't...
Thanks for your answer.
I've measured them as OD=31.5mm, Length=620mm and pitch as far as I can tell 20mm. Is there somewhere, like a catalogue or something, where I can find the corresponding screw?
I found a ball screw + nut and bearing at the scrapyard and decided to bring it home (scrap metal price, might as well) but I can't by the life of me identify it. The nut says "BE p23091 .30" which,...
Thanks for the replies. I'll give them a try and report back.
Can anyone suggest a good guide on what program to use to create a 2d toolpath? I want to cut out an axe handle but there's a bewildering amount of options out there and I don't know where to start....
I think I've fixed it. Don't know what I did wrong but it works now. I had to set the steps per mm to 80 though, which would mean that my steppers are set for 1/2 microstepping (they aren't)
I ran a...
Thanks for your input. I've been a bit busy but I'll give it a try and report back.
I have build a cnc machine and I'm controlling it using the Arduino uno and universal gcode sender. At least, I'm trying to control it. I'm trying to figure out how to set steps per mm and UGCS is...
It's finished, more or less. I found a pine table and used that as a spoils board. I need to zero it out with the mill. I made a test cut in aluminium with a mill I had lying around for 20 years for...
Heat shouldn't be a problem with the additional fan. I don't know about emf, but I think those devices are made to not be influenced by them. One thing I have noticed though, and I'm not sure if this...
Can anyone advise on bed material? A thick slab of aluminium would be ideal I think, but that's realy expensive. Could a slab of hardwood work as well?
