Hello all I have a control loop with of a motor that lifts a load. When I have a filter of 0.35hz on the loadcell, my load goes up and down smoothly with the control loop using 100lbs. when I set it to 0.7hz, I feel oscillations, in fact, when i go real slow, it almost feels like a stepper with 100lbs, with 40lbs works fine. I don't feel oscillations with 100lbs with the 0.35hz loadcell setting. so it appears i have a resonant frequency in the system with heavy weights. any suggestion on how to eliminate this? or isolate it
Thanks
Thanks
