text: <s>[INST] DECEL rate versus overshoot. I use PowerFlex 700 drive in Pos/Spd Prof mode (Speed/Torque Mod P88). I noticed that Decel Rate (p142) impact positionning overshoot. If I increase the value of Decel , the final positionning overshoot more . The step type is encoder abs. My logic tells to myself that the longer Decel is, better the final approch should be! It is very important to understand what is append because I need to increase the decel rate but I can’t tolerate important overshoot. Note : I tried to adjust P718 and P719 Position Regulation loop. This did not give good result. [/INST] have you set the inertia parameter? if the inertia is too low, the drive will try to decel too hard, and overshoot. if it is too high the drive will hunt for the final position. \\n </s>
