Alarm Name Meaning
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, Pn529 limits the speed
if the servomotor power 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 errors exceeds the value set for the excessive position error alarm
level (Pn520).
