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
SERVOPACK.
–
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
SERVOPACK.
–
A.030:
Main Circuit
Detector Error
A failure occurred in
the SERVOPACK.
–
The SERVOPACK may be
faulty. Replace the
SERVOPACK.
–
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
The motor parameter
file was not written to
the linear encoder.
(This applies only
when not using a
Serial Converter Unit.)
Check to see if the
motor parameter file
was written to the lin-
ear encoder.
Write the motor parame-
ter file to the linear
encoder.
*1
A failure occurred in
the SERVOPACK.
–
The SERVOPACK may be
faulty. Replace the
SERVOPACK.
–
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.
*1
A pin number that
does not exist on the
SERVOPACK was
allocated in Pn590 to
Pn5BC. (An alarm will
not occur, however, if
the signal is disabled.)
For input signals (Pn590
to Pn599), make sure
that the allocated pin
numbers are between
003 and 014.
For output signals
(Pn5B0 to Pn5BC),
make sure that the allo-
cated pin numbers are
between 023 and 031.
Allocate pins that actually
exist in Pn590 to Pn5BC.
