After estimating inertia, user can adjust parameters Pr.07-12, 07-13, and 07-14 separately by speed
response. The larger value of the setting, the faster response you will get. Pr.07-06 is switches the
frequency of low-speed/high-speed bandwidth.
PDFF Gain Value
Control mode
FOCPG FOCPM
Factory setting: 0
Settings 0~200%
Pr. 07-15, 07-16 is used to reduce overshoot situation. Please adjust PDFF gain value by actual
situation.
.
Besides traditional PI control, it also provides PDFF function to reduce overshoot for speed control.
