5.7.3 Overdamped response
If the graph shows that the response is overdamped (it reaches the demand too slowly, as
shown in Figure 39) then the value for KDERIV should be decreased to reduce the damping
of the move. If the overdamping is excessive, it may be necessary to increase the value of
KPROP.

and make the required changes. The ideal
response is shown in section 5.7.4.
