15.1 Errors and Warnings
15.1.1 About Errors and Warnings
When any operational unconformity occurs in the positioning unit RTEX, errors or warnings will occur.
When errors or warnings occur, the following operations will be performed.
Errors
Occurs in any abnormal conditions. When a motor is operating, the operation stops.
The motor stopped due to the occurrence of error will not activate until the error clear is
executed.
Warnings
Occurs when any operational unconformity not abnormal conditions exist.
The operation can continue even after the occurrence of warnings, and the motor
continues running if the motor is operating.
The errors and warnings can be confirmed on the data monitor and status monitor screens of the
Configurator PM.
The errors and warnings occur in the positioning unit RTEX and AMP.
The area that errors/warnings occurred and the details can be identified by the error/warning codes.
15.1.2 Error and Warning Logs
There are log areas to store the error/warning logs within the positioning unit RTEX.
Error log Max. 7 error codes can be stored for each axis (axes 1 to 8).
Warnings log Max. 7 warning codes can be stored for each axis (axes 1 to 8).
Once an error/warning occurs, the error/warning code will be stored in the log area of the axis that the
error occurred.
When an error/warning that is not related to the axes occurs, such as an failure in the unit, the
error/warning code will be stored in the log areas of all axes.
The latest error/warning codes for each axis can be checked with the Configurator PM.
When referring the error and warning logs for each axis, read the following shared memory from the PLC.
Error log area (Shared memory Bank 0) Warning log area (Shared memory Bank 0)
Number of occurrences of
errors/warnings

Error/warning annunciation
buffers (1 to 8)
