Error Codes for MS2000 and TG1000 Diagnostics
Error codes are dumped to the serial terminal with the last error code shown first using the 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.

Other Error Types
Command Syntax Error Codes
When a command is received that the controller cannot interpret, for one reason or another, an error is returned in the following format:
:N-<error code>
The error codes are as follows:
| Command Syntax Error Codes | |
|---|---|
| :N-1 | Unknown Command (not issued in TG-1000) |
| :N-2 | Unrecognized Axis Parameter (valid axes are dependent on the controller) |
| :N-3 | Missing Parameters (command received requires an axis parameter such as x=1234) |
| :N-4 | Parameter Out of Range |
| :N-5 | Operation Failed |
| :N-6 | Undefined Error (command is incorrect, but for none of the above reasons) |
| :N-7 | Invalid Card Address |
| :N-8 … :N-10 | Reserved |
| :N-11 … :N-20 | Reserved For Filterwheel |
| :N-21 | Serial Command Halted (by the HALT command) |
| :N-30 … :N-39 | Reserved |
