In the PM servo drive while using the ziegler nichols approach to tune the speed loop as a PI controller with no differential gain and set the values of ki=0 and kp=0.01 and running the motor at 500 rpm and using a step of 1% rated speed why we need to set the acceleration and deceleration to zero to record the speed response and steady state error?
