Hi,
I bought a bunch of TKD motorfaders (MF-914-B10K-10V) and I built this PID circuit to start tinkering with fader automation stuff.
This is my first time dealing with PID circuits. I used a signal generator for the target signal.
I managed to tune the circuit and get the fader moving smoothly and without overshoot as long as the target is moving quickly.
As soon as I decrease the frequency on the signal generator, the fader gets all stuttery and jumpy. I am not able to get the thing moving smoothly.
I have a bunch of these faders, both used and new, and the problem is the same with all of them, so I don't think the faders are the problem.
The motors are not the coreless version so they have more friction (as I understand).
I dont think the Integral part of the circuit is working. My intuition is that the integral component is more for longer term error correction, am I right? Or might this be the key to get it running smoothly?
Any ideas?
Thank you!
