3.2.33 Online Vibration Monitor (Fn207)
If vibration is generated during operation and this function is executed while the ser-
vomotor 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 automatically set.
In addition to this function, EasyFFT (Fn206) can be used to detect machine vibration
and automatically make notch filter settings.
If a Σ-V Series SERVOPACK is used to make adjustments, it is recommended that
you use advanced autotuning. This built-in function is used to maintain interchange-
ability with previous models. There is normally no need to use it.
(1) Preparation
The following conditions must be met to perform online vibration monitoring.
• The write prohibited setting (Fn010) must not be set to write-protect parameters.
• 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).
(2) Operating Procedure
Use the following procedure.
