Adjust the Proportional Gain (Kp) and
Derivative Gain 1 (Kvfb) values to ob-
tain the desired response characteris-
tics.
•
If the rising edge response is slow,
increase the Proportional Gain (Kp)
value.
•
If the amount of overshooting or os-
cillation is large, increase the
Derivative Gain 1 (Kvfb) value.
•
If the steady-state error is large, in-
crease the Integral Gain 1 (Ki) val-
ue.
•
Gradually increase each of the gain
values.
•
After you adjust each parameter, fin-
ish the tuning when the value of
Natural Frequency has stopped in-
creasing.
