IF (Intermediate Frequency) Vibration Suppression
The IF vibration suppression filter is used to process the speed deviation and compensated to the torque
reference. It is applied for the frequency range 100 Hz to 2000 Hz. Figure 9-20 shows the block diagram
of using the IF vibration suppression filter.

Pn173 determines the frequency center at which vibration suppression is to be performed.
Pn174 determines the vibration suppression bandwidth of the filter, indicating the range of the
adjustment filter near the center frequency. Increase this setting can increase the range of vibration
suppression, but it will affect the phase of the frequency near the center.
The highpass filter and the lowpass filter are respectively used to filter high frequency DC signals and
low frequency DC signals.
Pn178 determines the level of the final compensated IF vibration suppression.
