Note:
For the low rigidity load, low frequency vibration will be occurred continually at the front end of the load
during fast starting or fast stopping. The vibration may delay positioning time and affect the productive
efficiency.
The function of low frequency vibration suppression is embedded in ProNet series servodrives by
calculating the load position and compensating.

Application:
Low frequency vibration suppression function is enabled in both speed control mode and position
control mode.
Low frequency vibration suppression function is disabled or can not reach the expected effect in the
following condition.
�
Vibration is pricked up due to external force.
�
Vibration frequency is out of 5.0Hz to 50.0Hz
�
The mechanical connection part is at the mechanical clearance.
�
The time for movement is less than one vibration period.

Write the frequency data that measured(unit:0.1Hz) directly to Parameter Pn411, if the vibration
frequency can be measured by instrument (such as laser interferometer).And it also can be
measured indirectly by communication software ESView or FFT analyse function.
