3-10
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.

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.

A.042:
Parameter Com-
bination Error
The speed of program
jogging went below
the setting range
when the electronic
gear ratio (Pn20E/
Pn210) or the Servo-
motor was changed.
Check to see if the
detection conditions
*2
are satisfied.
Decrease the setting of
the electronic gear ratio
(Pn20E/Pn210).
*1
The speed of program
jogging went below
the setting range
when Pn533 or Pn585
(Program Jogging
Speed) was changed.
Check to see if the
detection conditions
*2
are satisfied.
Increase the setting of
Pn533 or Pn585.
*1
The movement speed
of advanced autotun-
ing went below the
setting range when
the electronic gear
ratio (Pn20E/ Pn210)
or the Servomotor
was changed.
Check to see if the
detection conditions
*3
are satisfied.
Decrease the setting of
the electronic gear ratio
(Pn20E/Pn210).
