Alarm Meaning
The servo was turned ON
after the position deviation
exceeded the setting of
Pn526 (Position Deviation
Overflow Alarm Level at
Servo ON) while the servo
was OFF.
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 (Position Devi-
ation Overflow 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 Safety
Option Module failed.
Detection of the Feedback
Option Module failed.
An unsupported Safety
Option Module was con-
nected.
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.
