D-value
compensates (Derivative). Reacts to fast
changes of engine speed/load.
A reduced value
(Fig 4.) gives a greater sensitivity to
fast changes of engine speed/load. Reduce the D-value
to reduce oscillations caused by fast changes.
An increased value
(Fig. 5)
gives a reduced sensitivity
to fast load changes. Increase the D-value to provide a
better ability to compensate for fast changes.
Adjustment of PID regulator
1. Start the engine.
2. Select the “Engine with mounting and equipment”
and then “Reinforcement and Stability, calibration”
function groups in the VODIA tool.
3. When calibration is started, certain conditions must
be met, such as that the engine must be running
and must have reached a certain engine tempera-
ture.
