Hello I want to ask question about tuning of servomotor. 1. In Calibration window I think missing FF3 parameter. Is it important to put FF3 into Calibration window? 2. Tuning also depends on parameters such as Max _Velocity and Max _Acceleration. Will it better to place those 2 parameters also into Calibration window?
3. I do jag with increment 0.1 and checking Hal Scope and looking to Pid.O.error and Xoutput to be with trapetsy shape. First part of trapetsy is acceleration of motor, Second part horizontal part of trapetsy indicates constant velocity of servomotor and Third part of trapetsy indicates deceleration of motor to the stop. Obviously to get good result be more difficult with reduction of jag increment. For instance reduce increment to 0.02 -0.01 . System in this case should work harder spend more power to accelerate faster to the max velocity speed, run with constant velocity and than decelerate to the zero RPM. My question is how to determine what jag increment should be?
