5.5.2 Underdamped response
If the graph shows that the response is underdamped (it overshoots the demand, as shown in Figure 12) then the value for KDERIV should be increased to add extra damping to the move. If the overshoot is excessive or oscillation has occurred, it may be necessary to reduce the value of KPROP.
