The following table shows the errors checked when power is turned ON.

Data destruc-

Parameters destruc-
tion
0001
When using the axis parameters in
the NC Unit, the parameters saved
in flash memory are lost. It is pos-
sible that, while saving to flash
memory, the NC Unit’s power sup-
ply was interrupted, there was
noise, or there was an error in
flash memory.
In this condition, only the data
transfer (read and write) and data
save operations can be performed.
The NC Unit’s axis parameters and
data are all returned to their
default values. After transferring
the parameters and data for all
axes, save the parameters and
either reset the power supply, or
restart the Unit. If the error per-
sists, it is possible that there is a
fault in flash memory, and so it
may be necessary to replace the
NC Unit.
Data destruction
0002
The following data saved in flash
memory will be lost:
Zones, positioning sequences,
speeds, acceleration/deceleration
data, positions, and dwell times.
It is possible that, while saving to
flash memory, the NC Unit’s power
supply was interrupted, there was
noise, or there was an error in
flash memory.
F-ROM check data
destruction
0003
The flash memory error data
saved in flash memory is lost
(OMRON maintenance data is
lost).
It is possible that, while saving to
flash memory, the NC Unit’s power
supply was interrupted, there was
noise, or there was an error in
flash memory.
When this error occurs, operation
can be continued by performing
error reset. Execute the next oper-
ation after performing error reset.
Common
parameters
Operating data area
designation error
0010
The operating data area designa-
tion (m) is incorrect.
•
Area designation: Set to a setting
other than 00, 0D, or 0E.
•
Bank designation: Set to a set-
ting not in the range 00 to 0C,
when 0E is set for the area desig-
nation.
In this condition, only the data
save operations can be performed.
All of the axes’ parameters and all
data will be returned to their
default values. After correcting the
common parameters, (refer to
SECTION 4
), reset the power sup-
ply or restart the NC Unit.
Operating data area
address designation
error
0011
The designation of the beginning
word of the operating data area’s
address (m+1) is outside the setta-
ble range.
Parameter designa-
tion error
0013
The axis parameter designation
(m+2) is not set to 00 or 01.
Axis designation
error
0014
The axis parameter designation
(m+2) is set to 01, but 1 is set for
an axis other than that for a 1-axis,
2-axis or 4-axis Unit.
Axis parame-
ters
Response timeout
0020
The axis parameters set in the
CPU Unit could not be read to the
NC Unit.
Increase the cycle monitor time set
with CX-Programmer and either
reset the power supply or restart
the NC Unit. If this error occurs
again, despite increasing the cycle
monitor time, it is possible that
there is a fault in the NC Unit or
somewhere in the PC. Either
replace the whole PC, or the NC
Unit.
