Error 1
(The
parameter
data in the
SERVOPACK
is
incorrect.)
The power supply voltage
suddenly dropped. Measure the power
supply voltage.
Set the power supply voltage within
the specified range, and set Fn005
to initialize the parameter.
The power supply went OFF
while changing a parameter
setting.
Check the
circumstances when
the power supply went
OFF.
Set Fn005 to initialize the
parameter and then set the
parameter again.
The number of times that
parameters were written
exceeded the limit.
Check to see if the
parameters were
frequently changed
through the host
controller.
The SERVOPACK may be faulty.
Repair or replace the SERVOPACK.
Reconsider the method of writing
parameters.
Malfunction caused by noise
from the AC power supply or
grounding line, static
electricity noise, etc.
Turn the power supply
ON and OFF several
times. If the alarm still
occurs, there may be
noise interference.
Take countermeasures against
noise.
Gas, water drops, or cutting
oil entered the SERVOPACK
and caused failure of the
internal components.
Check the installation
conditions. The SERVOPACK may be faulty.
Replace the SERVOPACK.
A SERVOPACK fault
occurred.
Turn the power supply
ON and OFF several
times. If the alarm still

Error 1
(The
parameter
data in the
SERVOPACK
is
incorrect.)
The software version of
SERVOPACK that caused the
alarm is older than that of
the written parameter.
Check Fn012 to see if
the set software
version agrees with
that of the
SERVOPACK. If not, an
alarm may occur.
Write the parameter of another
SERVOPACK of the same model with
the same software version. Then
turn the power OFF and then ON
again.
