∗
The alarm that may occur in a SERVOPACK with option module for fully-closed loop control.
Meaning
Position error pulses exceeded parameter
(Pn520).
Position error pulses accumulated too
much.
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).
Position error between motor and load is
excessive.
The safety function signal input timing is
faulty.
With the main power supply ON, voltage
was low for more than 1 second in phase-R,
-S or -T.
Digital operator (JUSP-OP05A) fails to
communicate with the SERVOPACK (e.g.,
CPU error).
