2 Check the anti-resonance frequency.
Use the servo analysis function to check the anti-resonance point.
Note 1 : The servo analysis function may fail to detect the anti-resonance point in the following
machine configuration.
1 Machines with much friction
2 Reduction gear, ball screw mechanism and other machines having relatively large
mechanical losses
Note 2 : Use the notch filter for the resonance point. Refer to page 5-52.

point
(Note 2.)
There are resonance point and anti-resonance point for the vibration of the machine.
The “resonance point” and “anti-resonance point” are machine characteristics viewed from the
motor.
“Resonance point”
... The end of the arm does not vibrate but the motor vibrates at the
frequency.
“Anti-resonance point” ... The motor shaft does not vibrate but the end of the arm vibrates at
the frequency.
Generally speaking the anti-resonance frequency is smaller than the resonance frequency.
