Alarm Code Alarm Name Possible Cause Confirmation Correction Reference
A.d02
(1d02h)
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 a position reference
is input and the set-
ting of Pn520 (Exces-
sive Position Devia-
tion Alarm Level) is
exceeded.
– Optimize the setting
of Pn520. Or, set
Pn529 or Pn584 to
an appropriate value.
A.d10
(1d10h)
Motor-Load
Position Devia-
tion Overflow
The motor direction
and external encoder
installation orientation
are backward.
Check the motor
direction and the
external encoder
installation orienta-
tion.
Install the external
encoder in the oppo-
site 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 cou-
pling.
Check the coupling
of the external
encoder.
Check the mechan-
ical coupling.

exceeded
±1,879,048,192.
Check the input ref-
erence pulse
counter.
Reconsider the oper-
ating specifications.

Error
A failure occurred in
the SERVOPACK.
– Replace the SERVO-
PACK.

PROFINET
Internal Syn-
chronization
Error 1
The PROFINET trans-
mission cycle fluctu-
ated.
– Remove the cause of
transmission cycle
fluctuation at the
host controller.
–
A failure occurred in
the SERVOPACK.
– Turn the power
supply to the SER-
VOPACK OFF and
ON again. If an
alarm still occurs, the
SERVOPACK may
be faulty. Replace
the SERVOPACK.

PROFINET
Module Inter-
face Communi-
cations Data
Error
Noise caused an error
in communications
between the SERVO-
PACK and PROFINET
Network Module.
– Implement counter-
measures against
noise.
