If, during operation or when starting up the CPU, the error indication occurs that the
memory of the overlay file system in the parametrization memory has overflowed, the
CPU can be restarted via
Safe Mode
as follows:
1.
Switch off the power supply of the CPU.
2.
Set the DIP switches S1 under the front flap to the following position:
S1
S1-1
S1-2
Action
0 1

2
ON
OFF
After PowerON the CPU starts in
Safe Mode
.
3.
Switch on the power supply of the CPU again.
ð
reserved exclusively for
Safe Mode
is enabled, which allows the CPU to restart
in the event of a memory overflow. At
Safe Mode
the CPU starts with a default
project, but your user programme is still present in the file system.
4.
Check your user program for files on the file system that cause the system to over-
flow, such as log files, recipes, motion data. Use an SSH client to access the file
system and delete the causing files if necessary. Then start in
Standard Mode
again.
5.
For this, switch off the power supply to the CPU.
6.
Set the DIP switches S1 to the default position:
S1
S1-1
S1-2
Action
0 1

OFF
OFF
After PowerON the CPU starts in

- default setting.
7.
Switch on the power supply of the CPU again.
ð
The CPU starts in
Standard Mode
again. If a project was loaded in Safe Mode,
it is executed in RUN operating mode.
4.5.2 Slot for Yaskawa SD card
n
You can only insert a Yaskawa SD card with a valid license file in this slot.
n
In the
WBM
at
‘Security
è
SD Card’
, you can enable or disable the use of the SD
card and call up information about it. By default, the use of the SD card is enabled.
Chap. 4.9.5.3 ‘SD Card’ page 99
n
An inserted Yaskawa SD card is only recognized by the CPU after PowerON.
n
If a new, unused Yaskawa SD card is detected after PowerON, the
overlay file system
FS
with user program, configurations, user data and firmware adjustments, is moved
from the internal parametrization memory to the Yaskawa SD card and deleted in the
internal parametrization memory. The CPU uses the overlay file system on the
Yaskawa SD card, now.
