(4) Vibration Detection Function
Set the vibration detection function to an appropriate value. 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 the servomotor is turned ON when position error pulses remain, the servomotor will return to the home posi-
tion and reset the number of pulses to zero. To prevent the servomotor from moving suddenly, select the
appropriate level for the Excessive Position Error alarm when the servomotor is ON to restrict operation of the
servomotor.

Occurs if the servo ON command is received when the number of position
error pulses is greater than the set value of Pn526.

Overflow Alarm by
Speed Limit at Servo ON
After a position error pulse has been input, Pn529 limits the speed if the
servo ON command is received. If Pn529 limits the speed in such a state,
this alarm occurs when the position references are input and the number of
position error pulses exceeds the value set for parameter Pn520 (Excessive
Position Error Alarm Level).
