6.4  Anti-Resonance Control Adjustment Function (Fn204)
6-27
 With Determined Vibration Frequency
6
Press the   Key. The cursor will move to "damp," 
and the flashing of "freq" will stop.
7
Select the digit with the   or   Key, and press 
the   or   Key to set the damping gain.
Example of measured waveform
Note: Increase the damping gain from about 0% to 
200% in 10% increments while checking the 
effect of vibration reduction. If vibration reduc-
tion is still insufficient at a gain of 200%, can-
cel the setting, and lower the control gain by 
using a different method, such as one-parame-
ter tuning.
8
If fine tuning of the frequency is necessary, press the 
 Key. The cursor will move from "damp" to 
"freq." If fine-tuning is not necessary, skip step 9 and 
go to step 10. 
9
Select the digit with the   or   Key, and press 
the   or   Key to fine-tune the frequency.
10
Press the   Key to save the settings. "DONE" will 
flash for approximately two seconds and "RUN" will 
be displayed.
11
Press the   Key to complete the anti-resonance 
control adjustment function. The screen in step 1 will 
appear again.
