CNC 6040 VFD/Spindle problem...
Hi
I bought a CNC 6040 a couple of weeks ago and i have some serious problems.
The machine and the controller for the stepper motors works ok. I have tried it out with Mach3 and it seems to function correctly. The build quality of the 'thing' is ok, not great, but its a robust piece of equipment.
My problem is that I cant get the spindle motor to function. I have programmed the VFD that came with the 0.8 kW water cooled spindle according to the instructions from the seller:
PD013 = 8 (factory reset)
PD005 = 400 Hz
PD004 = 400 Hz
PD003 = 400 Hz
The first time i started the motor ran for about 2 mins, with the water cooling running, then i stopped it as it seemed to be working.
Now when i press start on the VFDs control panel the motor jerks, runs maybe a turn or two and then the VFD trips with E.O.C.A (over-current).
I have checked and measured the cables for shortcuts and bad connections but they are ok.
I have tried to measure the resistance of the windings in the motor but i dont know what values are ok. If I measure between any two of the three windings i get next to 0 ohms ( maybe 3-5 ). Is this ok, or is it a sign that the motor is broken?
I have an ongoing discussion with the seller about the spindle problem ( and some other issues with missing cables and wrong sized collets ), but the seller acts a bit evasive and asks me to produce some sort of evidence of what is wrong. The seller told me to bring the VFD to someone who could check if it is broken. But i dont know of anyone who could do that.
I have even made a short movie clip and sent that to the seller since he says that all text is machine translated to chinese and that they have to see movies or pictures describing what the problem is.
Does anyone here have any advise on how to find out what the root cause of the problem is?
Edit: Personally I think the motor is broken. But how would I prove that it is the motor and not the VFD?
Many thanks

thanks

Here is. Inverter which you have is the same, but another name.

Hi,It just so happens that I think that I can help you with a VFD manual for a PRT-E1500w .I do not know how to download it (new here) so can Email if required regards coldte
Re: CNC 6040T E1500w VFD/Spindle problem...
Hi, The vfd you downloaded is not the one that I have,this one is specifically for the prt-E1500w water cooled router and front of console is a different layout.Would upload but not sure how,will e-mail if required. regards coldte
Re: CNC 6040 VFD/Spindle problem...
Hi, I have a similar machine ,A PRT_E1500w USB Router itself new. From what you have sent in post and what I have read (and Tried ) in other post about resetting vfd I reset with D0176. so perhaps we should both check! Personally I would switch to manual,configure D0001,D0032 and connect motor and run from console ,this will tell you for certain whether it is ok or not .Mine runs well and is fully adjustable.Please note you will not run without Resetting fault code(Been There) Hope this helps a bit
Re: CNC 6040 VFD/Spindle problem...
i WOULD VERY MUCH APPRECIATE THE VFD INFORMATION MANUAL FOR THE PRT-E1500W. i HOPE IT IS THE USB AND NOT THE PARALLEL PORT TYPE. IF SO MY E-MAIL ADDRESS IS [email protected]. if this helps you will be my HERO. THANK YOU SOOOOOOO MUCH. JLB1

This is a very old thread you should start a new one
