Effect of the tuning of Ti
For FcP 5020 system, the value of I controller (F3.13) can be in‐
creased to prevent pressure overshooting or converter over cur‐
rent, otherwise this value can also be reduced to improve the sys‐
tem performance.
Differential gain / D-gain [E3.16]
Kd (D gain, [F3.16]) works like a damping.
If there is a big overshoot in the system, then increase this value
in steps of 0.1 up to 1.0. However too high Kd would also lead to
an oscillation.
