I am using ACS550 for Winder in Winding Application. I want to run the Drive in Torque Control Mode. I have done following parameterization, I am not using any feedback at AI2 for torque control/selection, 9902=8, 9904=2, 2601=1, 2602=1, 2603=18, 2604=50, 2605=2, 2110= 30, 2401=0.3, 2402=0.25, As the load/torque applied to motor its RPM decreases but immediately with same load RPM increases. Please suggest what to do? Thank in advance.
