(5) Excessive Position Error Alarm Level at Servo ON
If Pn200.2 (Clear Operation) is set to a value other than zero, pulses used to determine position errors may
remain. If the servo is then turned ON, the servomotor will move to return to the home position and change 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 servo is ON to restrict operation of the servomotor.

Occurs if the /S_ON signal is turned ON when the number of position error
pulses is greater than the set value of Pn526.
After a position error pulse has been input, Pn529 limits the speed if the
/S_ON signal is turned ON. If Pn529 limits the speed in such a state, this
alarm occurs when reference pulses are input and the number of position
error pulses exceeds the value set for parameter Pn520 (Excessive Position
Error Alarm Level).
