8.3.4
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) when vibration is detected during machine
operation.
Set the initial vibration detection level to an appropriate value. Refer to the following section for
details.
6.11 Initializing the Vibration Detection Level
8.3.5
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.
