A.022:
System Check-
sum Error
(There is an error
in the parameter
data in the SER-
VOPACK.)
The power supply
voltage suddenly
dropped.
Measure the power
supply voltage.
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.
–
The power supply
was shut OFF while
setting a utility func-
tion.
Check the timing of
shutting OFF the power
supply.
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.
–
A failure occurred in
the SERVOPACK.
Turn the power supply
to the SERVOPACK
OFF and ON again. If
the alarm still occurs,
the SERVOPACK may
have failed.
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.

A.024:
System Alarm
(An internal pro-
gram error
occurred in the
SERVOPACK.)
A failure occurred in
the SERVOPACK.
–
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.
–
A.025:
System Alarm
(An internal pro-
gram error
occurred in the
SERVOPACK.)
A failure occurred in
the SERVOPACK.
–
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.
–
A.030:
Main Circuit
Detector Error
A failure occurred in
the SERVOPACK.
–
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.
–
A.040:
Parameter Set-
ting Error
(A parameter set-
ting is outside of
the setting
range.)
The SERVOPACK and
Servomotor capaci-
ties do not match
each other.
Check the combination
of the SERVOPACK and
Servomotor capacities.
Select a proper combina-
tion of SERVOPACK and
Servomotor capacities.
*1
A failure occurred in
the SERVOPACK.
–
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.
–
A parameter setting is
outside of the setting
range.
Check the setting
ranges of the parame-
ters that have been
changed.
Set the parameters to val-
ues within the setting
ranges.
–
The electronic gear
ratio is outside of the
setting range.
Check the electronic
gear ratio. The ratio
must be within the fol-
lowing range: 0.001 <
(Pn20E/Pn210) <
64,000.
Set the electronic gear
ratio in the following
range: 0.001 < (Pn20E/
Pn210) < 64,000.

Out-of-Range Origin
Setting
See if the origin is
between the settings of
Pn638 and Pn63A.
Set the origin between
Pn638 and Pn63A.
–
A.041:
Encoder Output
Pulse Setting
Error
The setting of Pn212
(Encoder Output
Pulses) or Pn281
(Encoder Output Res-
olution) is outside of
the setting range or
does not satisfy the
setting conditions.
Check the setting of
Pn212 or Pn281.
Set Pn212 or Pn281 to an
appropriate value.
