Operation Description
Set 0101 in parameter No. 2.
Set 1 in parameter No. 22.
Switch servo on and perform operation several
times.
Increase the setting of the fourth digit in
parameter No. 22 sequentially and execute step 3.
To reduce the settling time, increase the
response level of parameter No. 2 sequentially
and execute steps 2 to 4.
Auto tuning is selected.
Response is set to low level.
Machine resonance frequency: 1125Hz
Auto tuning is performed.
Check to see if vibration reduced.
The optimum value is achieved just before
vibration begins to increase.
