Appendix 1
When the Motion CPU detects an error with the self-diagnostic function, the error is displayed on the Motion CPU LED
display, and the error code is stored in the relevant device. Use the relevant device in which the error code is stored in the
program to enable a machine control interlock. By checking the error code, the error details and cause can be determined.
Refer to error checking methods for how to check the error details and error code. (Page 366 Error checking methods)

Error codes system

Error codes for all modules are expressed with 4 hexadecimal digits (integer without 16-bit sign). There are errors detected
with each module's self-diagnostic function, and common errors detected when communicating between modules. The error
detection types and error code ranges are shown below.
Error detection type
Detection with each module's self-
diagnostic function
Detection when communicating
between modules
Detailed information
When errors are detected during self-diagnosis, detailed information indicating the cause of the error is also stored.
Detailed information on each error code can be checked with the engineering tool. The following detailed information is saved
for each error code. (Up to two types of detailed information are stored, and the type differs for each error code.)
Detailed Item

Detailed Program positioning information
information 1
Drive and file name
Parameter information
System configuration information
Count information
Time information
G-code control information
Machine control information
Add-on function information
Servo error/error at communication
failure
Axis control error

Detailed Drive and file name
information 2
Parameter information
System configuration information
Detailed information on the latest error codes can also be checked from special registers (SD). Detailed information is stored
in "Detailed information 1 (SD81 to SD111)" and "Detailed information 2 (SD113 to SD143)". The stored information type is
determined with "Detailed information 1 information category (SD80)" and "Detailed information 2 information category
(SD112)".(Page 431 Special Registers)
