A.913:
Internal Tempera-
ture Warning 2
(Power Board Tem-
perature Error)
The surrounding
temperature is too
high.
Check the surrounding
temperature using a
thermostat. Or, check
the operating status
with the SERVOPACK
installation environ-
ment monitor.
Decrease the surrounding
temperature by improving
the SERVOPACK installa-
tion conditions.
–
An overload alarm
was reset by turn-
ing OFF the power
supply too many
times.
Check the alarm display
to see if there is an
overload alarm.
Change the method for
resetting the alarm.
–
There was an
excessive load or
operation was
performed that
exceeded the
regenerative pro-
cessing capacity.
Use the accumulated
load ratio to check the
load during operation,
and use the regenera-
tive load ratio to check
the regenerative pro-
cessing capacity.
Reconsider the load and
operating conditions.
–
The SERVOPACK
installation orien-
tation is not cor-
rect or there is
insufficient space
around the SER-
VOPACK.
Check the SERVO-
PACK installation con-
ditions.
Install the SERVOPACK
according to specifications.

A failure occurred
in the SERVO-
PACK.
–
The SERVOPACK may be
faulty. Replace the SERVO-
PACK.
–
A.920:
Regenerative Over-
load (warning before
an A.320 alarm
occurs)
The power supply
voltage exceeded
the specified
range.
Measure the power
supply voltage.
Set the power supply volt-
age within the specified
range.
–
There is insuffi-
cient external
regenerative resis-
tance, regenera-
tive resistor
capacity, or SER-
VOPACK capac-
ity, or there has
been a continuous
regeneration
state.
Check the operating
conditions or the
capacity using the Sig-
maJunmaSize+ Capac-
ity Selection Software
or another means.
Change the regenerative
resistance value, regenera-
tive resistance capacity, or
SERVOPACK capacity.
Reconsider the operating
conditions using the Sigma-
JunmaSize+ Capacity
Selection Software or other
means.
–
There was a con-
tinuous regenera-
tion state because
a negative load
was continuously
applied.
Check the load applied
to the Servomotor
during operation.
Reconsider the system
including the servo,
machine, and operating
conditions.
