4.5.2 Resonance Elimination Filter Function (High-Frequency
Resonance Elimination Filter)
(1) Overview
A filter function for removing high-speed resonance is added. With
this function, high-speed resonance can be removed to set a higher
velocity loop gain.

are restricted depending on the edition.
Edition of Series
90B0
Restriction
A(01) to I(09) Only resonance elimination filter 1 (conventional
specification) can be used. Resonance elimination
filters 2 to 4, damping setting, and active resonance
elimination filter cannot be used.
J(10) to O(15) Resonance elimination filters 1 to 4 (extended
specification) and damping setting can be used. The
active resonance elimination filter cannot be used.
P(10) or later All resonance elimination filter functions can be used.

This filter can be used as
a resonance elimination
filter designed to the
conventional specification.
It can follow the
resonance frequency.
(RE filter 1 only)
For this filter, it is
possible to specify
an attenuation
ratio.
(RE filters 1 to 4)
For this filter, it is
possible to specify
a bandwidth
freely.
(RE filters 1 to 4)
This filter can
handle up to four
resonance
frequencies.
