I have a CNC machine using 2 of your 850W servo's with a sigma7 controller, connected to the Y axis (mechanically connected). Is it possible to combine two motors for the auto tune feature and have one move in opposite direction from the other to have them move the axis into the same direction? Or is another method required?
@@istvanvarga3218 It's been a while, but you have to set the inertia value to start with; no actual auto-tune, but the best practice is to use the automated in-run tune; the Sigma 7's are so accurate with quite some processing power that it's advised in a dynamic load on a cnc to use that mode rather than the auto-tune method. But you need to set the inertia to start with. There normally is a formula to optimize the inertia (it was also in the manual of my cheap OMC stepperonline servo's). Based on the proper innertia value and the desired stiffness the controllers are capable to determine the optimal in-run tune realtime. So; no, there is no 'perfect' way to tune two motors at once; you just need to connect them both to the same laptop through USB and there is a feature in the Sigma software to set them up both at once. Hope this helps.
Thank you 🙏
Nice sir thank you
excexcellent

Hi!
Have you found finally solution to make the autotuning for the parallel connected servos?
