Re: Beginners

I use OrCAD Schematic Capture. There is Free Lite Version which is limited to a few dozen connections and a few dozen parts. You might Google Wiring Diagram Software . For something simple with just a few connections like we are asking you for most any drawing program can be used such as Windows Pai...

Re: Beginners

Could you give me an example of how the diagram should look like?
Here is one showing KStep Analog Connection to a VFD 0-10V input.

Others here.

Re: Beginners

Hi GS76, I want to be able to connect this DC controller within its 0-5V analog voltage interface to the JP33 5, 6 and 7 pins. If I am not mistaken? That should work. I believe the Rx pin is the analog input to the DC Controller. If you make a diagram we can check it for you. 1. How exactly would I ...

Re: Brushless AutoPhaseFind suggestions

Hi AZ, You are correct. As I tried to explain in your other Thread I think the issue is AutoPhaseFind rounding to 10 instead of 16. Some encoders have powers of 10 and some powers of 2. For example 2000 counts/rev vs 2048 counts per rev. The invDistPerCyle needs to be exact so the commutation will r...

Re: Brushless setup errors

Hi Az, I think the Auto Phase Find is not working correctly. It should rotate to find the index one direction twice then reverse. If you look at the Reports positions 1 and 2 are nearly the same. They should be one rev (probably 8192 counts) apart. After finding an index pulse there is an ignore per...

Re: Deciding on boards for a knee mill retrofit

Hi Moray,
500uS times 5000 gives 2.5 seconds, or 150RPM
I think that actually works out to 24RPM. But anyways less than 2.5 seconds seems reasonable to me.

Re: Deciding on boards for a knee mill retrofit

Hi Moray, Then have step/dirs and encoders split between JP7/JP5 on the KFlop, but then if my understanding/counting is correct, I'm going to run out of high speed digital inputs for all the index pulses (I'm assuming that any reasonable homing speed will be too fast to be reliably caught by a Konne...

Re: Brushless setup errors

Hi AZ, I'm not sure why you obtained that result. We'd need to see what was defined in AutoPhaseFind such as ENCODER_GAIN, the AutoPhaseFind Report, and what was entered into HomeBrushless. "locked up at a position" means that the commutation isn't working. With improper commutation full current to ...

Re: Travel Distance Calibration

Hi Cyprian, For instance when I move in 1" increments over a total distance of 5" I get a different result that if I move the entire 5" in one continuous movement. What results do you get? Are those different but repeatable? I have also discovered that when I send Gcode commands to move by 0.001" in...

Re: Travel Distance Calibration

Hi Cyprian,

In this case try:
10,204 x 6.0 / 6.012 = 10,183.6 counts/inch
