<3> Setting for an active resonance elimination filter
The active resonance elimination filter is a function for setting the
center frequency of a resonance elimination filter to the resonance
frequency so as to maintain a high stability even when the center
frequency deviates from the actual resonance frequency. It takes effect
when:
• The resonance frequency shifts as the axis moves.
• The resonance frequency varies from one machine to another
because of a difference among the machines.
• The resonance frequency changes with time.

ACREF(#3) The active resonance elimination filter is:
0 : Disabled
1 : Enabled
CAUTION
1 The active resonance elimination filter can be used
with the conventional specification of resonance
elimination filter 1. To use the active resonance
elimination filter, specify damping = 0 for
resonance elimination filter 1.
2 The active resonance elimination filter performs
follow-up operation over ±40 Hz with respect to a
specified center frequency.
3 The active resonance elimination filter becomes
enabled when the emergency stop is released.
4 The active resonance elimination filter does not
perform follow-up operation during acc./dec.
5 When the attenuation center frequency of
resonance elimination filter 1 is changed, the
center frequency is re-set to the specified center
frequency, and then the filter restarts follow-up
operation using this newly specified center
frequency as an initial value.
