I think I found the jumper Miglo was speaking of. Changing its position did not help. Also, each time I power up the VFD the spindle starts and I hit the stop button to halt it. Pressing run or any series of M3 commands not the Spindle On button seems to start it again.
Setting the jumper on 1-2 keeps the spindle from starting on power up
Which of Julien’s posts? I’m having the same problem you are, and want to make sure I’m referring to the correct one. Did using his settings resolve your problem? I’m about to give up on the whole thing and get a new machine that was purpose-built to use a spindle and computer speed control.
Dan, Thanks. That’s the thread I was thinking of. I’m still having the same problem you were having; as soon as the VFD boots up, the spindle starts running, and that is with the jumper in the correct (Pin 1-2) position and PD001/PD002 both set to 1. I hit STOP on the VDF, and the spindle never runs again. I’m seeing the correct voltage from the CM board, measured both at the board with the VFD disconnected, and at VI / ACM when connected. I tried a PD 013 reset and re-entered everything, but still no joy.
I know you said you re-entered everything, it’s just a double check. Having PD011 set to something different from 0 would produce the same effect you are seeing. This is the “Frequency lower limit” parameter: the idea is that when you have an air-cooled spindle, it is important that the spindle never goes below a given minimal RPM, because then the fan would not produce enough airflow to cool the spindle when running. Since we are working with PD001/PD002 set to 1, this essentialy means that the “Run” button is ignored, and the spindle runs at whatever RPM is commanded by the VI signal from the Shapeoko. If PD011 was non-zero, when the Shapeoko sends 0V (as it does while idle), the VFD will spin the spindle at the frequency set in PD011, not 0 RPM.
This is assuming you are indeed using a water-cooled spindle. I’m sure people here who use air-cooled spindles could comment on how they setup their VFD parameters.
Sorry to hear you are still having issues. With the help of my wife I went through each and every one of the settings Julien posted, even the ones he didn’t change or highlight and made sure the jumper was correct and things started working.
Also, once you get past this, if you are using a sender other than CM be sure to go over all of your gcode parameters. If you don’t perform the step of homing followed by entering G28.1 in the console you will have issues as well.
Dan,
Thanks again. I’m going to re-run everything again today. Do you have a particular power-up sequence you use? I’m wondering if I should have CM up and connected to the Shapeoko BEFORE powering up the VFD at all?
Julien,
Yes, thanks. I need to try seeing PD011 to 0 again and check that. I think I may not have had the other settings correct when I had it set to zero before. I’ve got an air-cooled spindle, but I don’t think setting PD011 to 0 is a problem. I understand that once spinning an air-cooled spindle needs higher RPMs to dissipate the heat than what a water-cooled spindle needs, but I can set my minimum RPM in Carbide Motion to ensure I keep the RPMs up any time the spindle is running.
On a side note, for you or Dan or anyone else who wants to comment: I’m not completely comfortable with the idea of shorting DCM to FOR directly. I feel like it would be safer to to put a toggle switch inline just to prevent any stray voltage on VI from spinning the shaft while I’m doing a endmill change. Thoughts?
The problem is that adding a toggle switch on any of these signals will not necessarily bring additional safety, the likelihood of an internal failure is similar to the likelihood of something weird happening on VI signal. The only completely safe way is to remove power, i.e. turn off the VFD while changing tools…
HI,
I’m following your steps and almost there…I hope
You wrote “Change $30 to 24000 in the GBRL setting – this states that at maximum output of 5v on PWM will be 24000rpm – as default this would be 10,000 or 12000 rpm.”
My question is how to change $30? I am running Carbide Motion 513 running Carbide 3d 2.4d board.
Hi Julien,
I followed a lot of your posts, so i thought I could shoot you a question. I am trying to upgrade to a 1.5kw 110v spindle. The VFD I have is a different model than most on the forums. It is a YL620-A model.
I am trying to figure how to properly wire it to the board. I am wondering where does the two cables (however my spindle has three wires…) from the board should wire in the vfd. Also I saw there is a wire to loop between two connectors inside the vfd to allow speed input from the g-code…
I am bit at loss, I am not proficient in electronics unfortunately.
Here is a picture of the vfd:
