(4) Vibration Detection Function
Set the vibration detection function to an appropriate value with the vibration detection level initialization
(Fn01B). For details on how to set the vibration detection function, refer to 6.16 Vibration Detection Level
Initialization (Fn01B).
(5) Excessive Position Error Alarm Level at Servo ON
If position errors remain in the error counter when turning ON the servomotor power, the servomotor will
move and this movement will clear the counter of all position errors. Because the servomotor will move sud-
denly and unexpectedly, safety precautions are required. To prevent the servomotor from moving suddenly,
select the appropriate level for the excessive position error alarm level at servo ON (Pn526) to restrict opera-
tion of the servomotor.

A.d01
Position Error Overflow
Alarm at Servo ON
This alarm occurs if the servomotor power is turned ON when the position
error is greater than the set value of Pn526 while the servomotor power is
OFF.
A.d02
Position Error Overflow
Alarm by Speed Limit at
Servo ON
When the position errors remain in the error counter, Pn584 limits the speed
if the servomotor power is turned ON. If Pn584 limits the speed in such a
state, this alarm occurs when position references are input and the number of
position errors exceeds the value set for the excessive position error alarm
level (Pn520).
