====== Error Codes for MS2000 and TG1000 Diagnostics ======

Error codes are dumped to the serial terminal with the last error code shown first using the [[commands:dump|DU Y command]].

If you're looking for [[#command syntax error codes]] such as ''N-1'', ''N-2'', etc you can find a table at the bottom of the page.

If you're looking for [[#filter wheel error codes]], they are listed at the bottom of the page.

†  The last digit indicates the axis number that is in error in controller ordering starting from 0.  E.g. on three-axis units ''X=0'', ''Y=1'', and ''Z=2''; on single-axis MFC units, ''Z=0''.

**FATAL** errors cause the controller to halt motion on the axis that has the error. A commanded move will not be completed to the desired precision if a FATAL error occurs.

**RECOVERABLE** errors do not stop the controller from attempting to complete a commanded move. Large numbers of recoverable errors should be taken as a warning. Frequent servo errors (numbers 90-92) often mean that the speed is near or exceeding the stage maximum.  Frequent overtime errors (numbers 1-9) often mean that competing processes, such as over-frequent serial status requests, are using too much CPU time.
