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 section for
details.
6.10 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.

A.d01
Position Deviation
Overflow Alarm at
Servo ON
This alarm occurs if the servo is turned ON after the position devia-
tion exceeded the setting of Pn526 (Excessive Position Deviation
Alarm Level at Servo ON) while the servo was OFF.
A.d02
Position Deviation
Overflow Alarm for
Speed Limit at Servo
ON
If position deviation remains in the deviation counter, the setting of
Pn529 or Pn584 (Speed Limit Level at Servo ON) will limit the speed
when the servo is turned ON. This alarm occurs if a position refer-
ence is input and the setting of Pn520 (Excessive Position Deviation
Alarm Level) is exceeded.
