This warning occurs if the position deviation
exceeds the specified percentage (Pn520 × Pn51E/
100).
9.4.5 Vibration Detection Level Setting
You can set the vibration detection level (Pn312) to more accurately detect A.520 alarms
(Vibration Alarm) and A.911 warnings (Vibration Warning) when vibration is detected
during machine operation.
Set the initial vibration detection level to an appropriate value. Refer to the following sec-
tion for details.

9.4.6 Setting the Position Deviation Overflow Alarm Level at Servo ON
If the servo is turned ON when there is a large position deviation, the Servomotor will
attempt to return to the original position to bring the position deviation to 0, which may
create a hazardous situation. To prevent this, you can set a position deviation overflow
alarm level at servo ON to restrict operation.
The related parameters and alarms are given in the following tables.
