B Diagnostic messages
If an error occurs, the motor controller CMMP‐AS‐...‐M3/-M0 shows a diagnostic message cyclically in
the 7-segments display. An error message consists of an E (for Error), a main index and sub-index,
e.g.: - E 0 1 0 -.
Warnings have the same number as an error message. In contrast to error messages, however,
warnings are preceded and followed by hyphens, e.g. - 1 7 0 -.
