5.6 Anti-Resonance Control Adjustment Function (Fn204)
Keys
Press the Key while "Tuning Mode = 0" is dis-
played. The screen shown on the left will appear. The
detection of vibration frequencies will start and
"freq" will blink.
Note: Return to step 3 if vibration is not detected.
Lower the vibration detection sensitivity
(Pn311). When this parameter is lowered, the
detection sensitivity will be increased. Vibra-
tion may not be detected accurately if too small
value is set.
The vibration frequency will be displayed if vibration
is detected.
Press the Key. The cursor will move to "damp,"
and "freq" will be displayed normally.
Select the digit with the
the or
Note:
Increase the damping gain from about 0% to 200% in
10% increments while checking the effect of vibra-
tion reduction. If vibration reduction is still insuffi-
cient at a gain of 200%, cancel the setting, and lower
the control gain by using a different method, such as
one-parameter tuning.
Press the Key. The cursor will move from
"damp" to "freq".

this step and go to step 10 if the fine-tuning of the fre-
quency is not necessary.
