d01 hex:
Position Devia-
tion Overflow
Alarm at Servo
ON
The servo was turned
ON after the position
deviation exceeded
the setting of Pn526
(2526 hex) (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 (2526 hex).
d02 hex:
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 (2529
hex) or Pn584 (2584
hex) (Speed Limit
Level at Servo ON) will
limit the speed when
the servo is turned
ON. This alarm occurs
if a position reference
is input and the set-
ting of Pn520 (2520
hex) (Excessive Posi-
tion Deviation Alarm
Level) is exceeded.
–
Optimize the setting of
Pn520 (2520 hex). Or, set
Pn529 (2529 hex) or
Pn584 (2584 hex) to an
appropriate value.
d10 hex:
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 (2002
hex) = 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.

d30 hex:
Position Data
Overflow
The position data
exceeded
±
1,879,048,192.
Check the input refer-
ence pulse counter.
Reconsider the operating
specifications.
–
E00 hex:
EtherCAT Module
Interface Initializa-
tion Timeout Error
A failure occurred in
the SERVOPACK.
–
Replace the SERVO-
PACK.
–
E02 hex:
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.
–
E03 hex:
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.
