CHAPTER 5 SERVO ADJUSTMENT
5-30
Special Adjustment (Vibration Suppression)
5
(1) Adjusting the servo gain
To ignore the vibration of the tip of the machine and reserve smooth stopping action of the
servomotor free from overshoot, refer to the description given in sections 5.1 through 5.7 to adjust
the servo gain.
If gain-related parameters are adjusted after the vibration suppressing anti resonance
frequency is set, the vibration suppressing anti resonance frequency must be adjusted
again. Perform gain adjustment first.
(2) Checking the vibration suppressing anti resonance frequency
Using the PC Loader
Use the servo analyze function to check the vibration suppressing anti resonance point.
Note 1 The vibration suppressing anti resonance point may not be observed with the servo
analyze function in the following machine configuration.
Machine with large friction
Machine with relatively large mechanical loss such as reduction gear and ball screw
Note 2 Use the notch filter for the resonance point.
What are the resonance point and vibration suppressing anti resonance point?
Vibration of the machine includes the "resonance point" and "vibration suppressing anti
resonance point."
The "resonance point" and "vibration suppressing anti resonance point" mentioned
here are machine characteristics viewed from the motor.
"Resonance point": Frequency at which the motor vibrates without arm tip vibration
"Vibration suppressing anti resonance point": Frequency at which the arm tip vibrates
without vibration of the motor shaft
In general, the vibration suppressing anti resonance frequency is less than the
resonance frequency.
