Notes on the tables below
The diagnostic register of the module includes both status bits and the diagnostic code
(see "Dev-Diag-LPSDO (LPSDO diagnostics)" on page A-18). This diagnostic code, which
is shown in bits 10 to 0 of the register, is listed in the tables below starting from Table 8-4).
However, it is the code of the entire diagnostic register that is indicated. To obtain the
diagnostic code specified in the documentation, logically AND the code of the diagnostic
register indicated with the code 07FF
Diagnostic code indicated: 2290

0 -> X (not relevant)
Diagnostic code specified in the documentation: X290
As the first digit is never relevant, the code always starts with an X.
If the same error can occur at different outputs/channels, a generalizing diagnostic code is
indicated with an n where the error location is specified.
Generalizing diagnostic code specified in the documentation: X03n
For some errors a single channel is specified as the error location (e.g., OUT0_Ch1).
Some errors only occur for outputs parameterized for two-channel operation. Here, the
channel pair is specified as the error location (e.g., OUT0_Ch1&2).
Safe output errors (Table 8-4)
Error cause
Short circuit or overload
X030: OUT0_Ch1
X031: OUT1_Ch1
X032: OUT2_Ch1
X033: OUT3_Ch1
003n
Short circuit or overload
003n
Error location
This means, for example:
X032
Cross circuit at OUT2_Ch1 (output 2 channel 1)
X03A
Cross circuit at OUT3_Ch2 (output 3 channel 2)
