Prevention
The life of the Battery in the CPU Unit
has expired.
Replace the Battery in the CPU Unit,
reset the error, and perform homing to
define home.
Periodically replace the Battery in the
CPU Unit. Refer to the

Unit Hardware User's Manual
(Cat.
No. W500) for information on the Bat-
tery life.
Backup memory failure
If the error occurs even after the
above correction is performed, CPU
backup memory has failed. Replace

Prevention
The power supply to the Controller
was interrupted or communications
with the Sysmac Studio were discon-

control parameter settings or clearing
memory.
Download the MC parameters from
the Sysmac Studio.
Do not turn OFF the power supply
during save processing for the param-
eters.
Non-volatile memory failure
If the error occurs even after the
above correction is performed, non-
volatile memory has failed. After you
replace the CPU Unit, download all
settings including the Axis Settings
from the Sysmac Studio.
