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).
