Omron FQM1-MMP21 用户手册

Errors in the FQM1 can be broadly divided into the following three categories.

There are basically four sources of information on errors that have occurred:

• The LED indicators on the front of the Coordinator and Motion Control

Modules

• The Auxiliary Area Error Flags

• The Auxiliary Area Error Contents Words

• The Auxiliary Area Error Code Word

When two or more errors occur at the same time, the highest (most serious)
error code will be stored in A400.

The following table shows the status of the FQM1’s indicators for errors that
have occurred in RUN or MONITOR Mode.
