A.d01:
Position Devia-
tion Overflow
Alarm at Servo
ON
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.
Check the position
deviation while the
servo is OFF.
Set the position deviation
to be cleared while the
servo is OFF.
Optimize the setting of
Pn526 (Position Deviation
Overflow Alarm Level at
Servo ON).

A.d02:
Position Devia-
tion Overflow
Alarm for Speed
Limit at Servo ON
If position deviation
remains in the devia-
tion counter, the set-
ting 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 setting
of Pn520 (Position
Deviation Overflow
Alarm Level) is
exceeded.
–
Set the position deviation
to be cleared while the
servo is OFF.
Optimize the setting of
Pn520 (Position Deviation
Overflow Alarm Level). Or,
adjust the setting of
Pn529 or Pn584 (Speed
Limit Level at Servo ON).
A.d10:
Motor-Load Posi-
tion Deviation
Overflow
The motor direction
and external encoder
installation orientation
are backward. Check the motor direc-
tion and the external
encoder installation ori-
entation.
Install the external
encoder in the opposite
direction, or change the
setting of Pn002 =
n.X

(External
Encoder Usage) to
reverse the direction.

There is an error in the
connection between
the load (e.g., stage)
and external encoder
coupling.
Check the coupling of
the external encoder. Check the mechanical
coupling.

A.d30:
Position Data
Overflow
The position data
exceeded
±
1,879,048,192.
Check the input refer-
ence pulse counter. Reconsider the operating
specifications.

A.E71:
Safety Option
Module Detec-
tion Failure
There is a faulty con-
nection between the
SERVOPACK and the
Safety Option Module. Check the connection
between the SERVO-
PACK and the Safety
Option Module.
Correctly connect the
Safety Option Module.
–
The Safety Option
Module was discon-
nected.
–
Execute Fn014 (Reset
Option Module Configura-
tion Error) from the Digital
Operator or S
and then turn the power
supply to the SERVO-
PACK OFF and ON again.

Module.
–
Replace the Safety Option
Module.
–
A failure occurred in
the SERVOPACK.
–
Replace the SERVO-
PACK.
