Vib Detect
Button
While the notch filter or anti-resonance control adjustment automatic setting function is
enabled, you can click the
Vib Detect
Button to manually detect vibration. When you
click the
Vib Detect
Button, the SERVOPACK will detect vibration at that time, and set
the notch filter frequency (stage 1 or 2) or anti-resonance control frequency that is
effective for the detected vibration. You can also perform manual vibration detection
even when the SERVOPACK does not detect vibration.

Operation
1
The positioning time is measured after the moment of inertia
ratio (Pn103) is set correctly.
Tuning is completed if the specifications are met.
The tuning results are saved in the SERVOPACK.
2
The positioning time will be reduced if the feedforward level is
increased.
Tuning is completed if the specifications are met. The tuning
results are saved in the SERVOPACK.
If overshooting occurs before the specifications are met, pro-
ceed to step 3.
3
Overshooting will be reduced if the feedback level is
increased.
If the overshooting is eliminated, proceed to step 4.
