6.22 Online Vibration Monitor (Fn207)
If vibration is generated during operation and this function is executed while the servomotor power is still ON,
the machine vibration can sometimes be suppressed by setting a notch filter or torque reference filter for the
vibration frequencies.
When online, vibration frequency caused by machine resonance will be detected and the frequency that has
the highest peak will be displayed on the panel operator. The effective torque reference filter or notch filter
frequency for the vibration frequencies will be automatically selected and the related parameters will be auto-
matically set.
In addition to this function, EasyFFT (Fn206) can be used to detect machine vibration and automatically make
notch filter settings. Use the following flowchart to determine how these functions should be used.
If a Σ-V large-capacity SERVOPACK is used to make adjustments, it is recommended that you use advanced
autotuning. This built-in function is used to maintain interchangeability with previous models. There is nor-
mally no need to use it.
(1) Preparation
The following conditions must be met to perform online vibration monitoring.
The write prohibited setting parameter (Fn010) must be set to Write permitted (P.0000).
The servomotor power must be ON.
There must be no overtravel.
The correct moment of inertia (Pn103) must be set.
The test without a motor function must be disabled (Pn00C.0 = 0).
