Position Error Pulse
Overflow Alarm by Speed
Limit at Servo ON
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 refer-
ence pulses are input and the number of
position error pulses exceeds the value set
for parameter Pn520 (Excessive Position
Error Alarm Level).
