Tuning 2 servo at same time (master/slave axis)

Post by rdpdo2002 » Fri Mar 29, 2019 1:55 pm

Hello,

I need to tune an axis with 2 servo (master/slave). I think I will do that like if it was an unique servo, so I will view the step response of only one servo (the master ?) Is it correct ?

I don't think it is possible to view the response of the 2 servo simultaneously ?


Do you have some special recommandation to tune a master/slave axis ? Some error to avoid ?

Thanks you very much.

Is there a way to observe in step response screen the position of the slave axis together with the position of the master?

Hi cnc_freak,

Not with the Step Response Screen. Since they both follow the same trajectory if you verify one follows the trajectory properly and also the other that is usually sufficient.

Otherwise you could use a User C Program to capture the data and then analzye it yourself with some application like Excel. See the CaptureXYMotionPosDest.c example.
