Alarm Meaning
If position deviation remains
in the deviation counter, the
setting of Pn529 or Pn584
(Speed Limit Level at Servo
ON) limits the speed when
the servo is turned ON.
This alarm occurs if reference
pulses are input and the set-
ting of Pn520 (Excessive
Position Deviation Alarm
Level) is exceeded before the
limit is cleared.
There was too much position
deviation between the motor
and load during fully-closed
loop control.
The position feedback data
exceeded ±1,879,048,192.
Detection of the Feedback
Option Module failed.
An error occurred in the input
timing of the safety function
signal.
An error occurred in the gate
drive circuit.
An error occurred in the gate
drive circuit.
The voltage was low for more
than one second for phase
R, S, or T when the main
power supply was ON.
The Servomotor did not
operate or power was not
supplied to the Servomotor
even though the /S-ON
(Servo ON) signal was input
when the Servomotor was
ready to receive it.
An internal program error
occurred in the SERVO-
PACK.
Communications were not
possible between the Digital
Operator (model: JUSP-
OP05A-1-E) and the SERVO-
PACK (e.g., a CPU error
occurred).
