Notch Filters
Digital notch filters, a feature of Servosila SC-series servo drives, are specialized band-reject filters used to suppress mechanical resonances, high-pitched squealing, and vibration by attenuating specific narrow bands of frequencies. They allow for higher servo PID gains and improving machine responsiveness in general.

Linear axes of CNC machines are particularly susceptible to mechanical resonances. The adverse effects are rectified by configuring the Notch Filters to match the resonance frequencies. The digital filters are configured via "Servoscope" software that accompanies all Servosila servo drives.
