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 position references are input
and the number of position errors exceeds the value set
for the excessive position error alarm level (Pn520).
