(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 7.16 Vibration Detection Level Initialization (Fn01B)
(5) Excessive Position Error Alarm Level at Servo ON
If Pn200.2 (Clear Operation) is set to value other than zero, the position error pulses will remain at the base-
block. If the servomotor is moved by an external force while it is being baseblocked, the servomotor will
return to the original position so that the position error pulses are cleared and reset to zero after the servo is
turned ON. This setting is used to limit such motions and to detect any errors.

Setting Range
0 to 10000
The parameter Pn584 (Speed Limit Level at Servo ON) is used to limit the servomotor speed when returning
to the original position to clear the accumulated position error pulses and reset the pulses to 0. The speed will
be limited until the position error pulses are reset to 0.

These alarms will be occur if the number of position error pulses accumulated before the servo turns ON is
greater than the setting of Pn526 (Excessive Position Error Alarm Level at Servo ON).
When an alarm occurs, refer to 9 Troubleshooting and take the corrective actions.

Alarm Name
Position Error Pulse
If the servomotor runs without clearing the position error pulses while the
Overflow Alarm at Servo
servo is OFF, excessive position error pulses are accumulated.
ON
If the servo turns ON with position error pulses accumulated, the speed is
Position Error Pulse
limited by Pn584. In this state, the reference pulse is input without resetting
Overflow Alarm by
the speed limit, and the position error pulses exceeds the value set for the
Speed Limit at Servo ON
parameter Pn520.
