5.6.4.4 Other Operations and Checks on Error

 Other errors
This section describes common errors that are generated when sequence programs are written.
Note that messages in displayed dialogs may not indicate the correct error status for CNC because they are for MELSEC PLC
center. Status is displayed as the last 4 digits of the display number.
For details of other errors, refer to "5.13.1 List of Errors during GX Works2 Online Operation".
Status Message
Writing of data which exceeds the ca-
pacity of the PLC was attempted. Exe-
4005 cute again within the capacity of the
(*1) PLC.
Cannot write because the PLC is exe-
4010 cuting a RUN command. Stop the PLC,
then execute again.
The applicable drive is not ready.
4021
Insufficient file capacity. Execute again
4029
after deleting unnecessary files.
The file is write protected. Change the
4052
file attributes to enable writing to the file.
A mismatch occurred between the PLC
and peripheral parameters. Match the
4065
parameters between the PLC and pe-
ripherals.
The program before correction differs
from the registered program.
4070
Cause
The maximum number of steps that can
be executed with NC has been exceed-
ed.
The PLC of the NC is running.
The specified target memory does not
exist or is not in a usable status.
An attempt was made to write a file that
exceeds the storage capacity.
The specified target memory is a write-
disabled device (CNC ROM).
There is a problem in the device setting
value.
A ladder instruction outside the specifi-
cation is included.
133
Remedy
Check the size of execution area. (Re-
fer to "How to check size of area for ex-
ecution" of this section.)
Reduce the number of steps for the se-
quence program to be executed accord-
ing to that value.
After stopping the PLC of the NC, start
execution again.
Change the target memory.
Examine the file structure so that the
data falls within the limited capacity.
Specify "Program memory/Device
memory" as the target memory.
Set the number of device points.
