d01h:
Position Devia-
tion Overflow
Alarm at Servo
ON
The servo was turned
ON after the position
deviation exceeded
the setting of Pn526
(2526h) (Excessive
Position Deviation
Alarm Level at Servo
ON) while the servo
was OFF.
Check the position
deviation while the
servo is OFF.
Optimize the setting of
Pn526 (2526h).

d02h:
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 (2529h)
or Pn584 (2584h)
(Speed Limit Level at
Servo ON) limits the
speed when the servo
is turned ON. This
alarm occurs if a posi-
tion reference is input
and the setting of
Pn520 (2520h)
(Excessive Position
Deviation Alarm Level)
is exceeded.
–
Optimize the setting of
Pn520 (2520h). Or, set
Pn529 (2529h) or Pn584
(2584h) to an appropriate
value.
d10h:
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 (2002h)
= n.X

(External
Encoder Usage) to
reverse the direction.
page 11-6
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.

d30h:
Position Data
Overflow
The position data
exceeded
±
1,879,048,192.
Check the input refer-
ence pulse counter. Reconsider the operating
specifications.

E00h:
EtherCAT Module
Interface Initializa-
tion Timeout Error
A failure occurred in
the SERVOPACK.
–
Replace the SERVO-
PACK.
–
E02h:
EtherCAT Inter-
nal Synchroniza-
tion Error 1
The EtherCAT trans-
mission cycle fluctu-
ated.
–
Remove the cause of
transmission cycle fluctu-
ation at the host control-
ler.
–
A failure occurred in
the SERVOPACK.
–
Turn the power supply to
the SERVOPACK OFF and
ON again. If an alarm still
occurs, the SERVOPACK
may be faulty. Replace the
SERVOPACK.
–
E03h:
EtherCAT Mod-
ule Interface
Communications
Data Error
Noise caused an error
in communications
between the SERVO-
PACK and EtherCAT
Network Module.
–
Implement countermea-
sures against noise.
–
A failure occurred in
the SERVOPACK.
–
Replace the SERVO-
PACK.
