10) Using Filters
ABSODEX fitted to a low rigidity load equipment may resonate with the equipment.
For such application, the built-in digital filters (low pass and notch filters) will help reduce
resonance to some extent.
Parameters 62 to 71 are for filters. For detail, refer to Table 7.1.
(1) Characteristics of Filters
Low pass filter helps attenuate signals in high frequency band, while notch filter helps
attenuate signals in a specific frequency. Using these characteristics enables to
attenuate signals of a specific frequency to control resonance.
The diagram in the following Fig. 7.10 illustrates the frequency characteristics.
