Problem 6. Vibration and abnormal noise
Cause Remedy
Tuning parameter settings
are not appropriate.
Set the Control Gain 1, Control Gain 2, Integral Gain to lower values.
Especially for highly rigid equipment such as ball screws, set the
Current
control gain (No.193.0) to "1" if noise occurs at servo-on stop.
7 Tunings
Cranky or loose machines and
equipment
Check the installation of the motor, decelerator, couplers, and so on.
Noise interference is occurring.
Check the length or shield of each cable.
Isolate the high voltage cable such as motor power cable from the signal cable
such as encoder cables.
The equipment and the motor are
resonating.
For low-frequency vibration, adjust the position command smoothing filter.
For high-frequency vibration, adjust the low-pass filter or notch filter.
Motor load is substantially large
(*)
(Alarm No.7 is displayed)
Set the inertia condition parameter to "Heavy"
Keep adjusting the Position Command Smoothing Filter to smooth command
until the vibration at the time of acceleration becomes eliminated.
Set the
Inertia ratio (No.102.0) to 3,000.
To stabilize the motions, increase Integral gain value according to Control
Gain 1 and Control Gain 2.
The current pairing of amplifier
and motor is not right.
Check the motor model code under "Communication Settings" tab in "Servo Studio".
In case of wrong pairing, clear the parameters saved in EEPROM and change
the motor model code.
*) This problem may occur in a low-rigidity case such as belt drive whose load inertia ratio is over 30 times.
The motor is experiencing vibration or abnormal noise.
