[1] Damping characteristic coefficient 1,2 (Parameter No.97, 98, 101, 102, 105, and 106)
Do not change.
[2] Natural frequency [1/1000Hz] (Parameter No.99, 103 and 107)
Set the natural frequency of the load measured. It can be input directly to the parameter
from the frequency analysis tool for anti-vibration control included in the PC software if the
tool is already used. [Refer to the Instruction Manual of the PC software.]
Set the specific frequency of the loaded object close to the setting so a higher anti-vibration
performance can be obtained.
[Reference] Other vibration measuring methods
� Use of measuring instrument such as vibration meter and acceleration
pickup
� Calculation from video image data
[3] Notch filter gain (Parameter No.100, 104 and 108)
Set the notch filter gain following the table below in response to the measured specific
frequency of the loaded object. See the table below for reference. Provide fine adjustment if
overshooting occurs.
If the notch filter gain setting is too high, overshooting would occur during the settling time.
If the notch filter gain setting is too low, undershooting would occur during the settling time.
