Values for error behaviour (see 1029h)
0 = pre-operational (only if current state is operational)
1 = no change of state
2 = stopped
3 .. 127 = reserved

Error register (OD index 1001h)
The error register indicates the general error status of the device. Every bit stands
for an error group. If a bit is set (= 1), at least one error of this group is active at
the moment. The contents of this register are transmitted in every emergency
message (EMCY).

Pre-defined error field (OD index 1003h)
Each inclination sensor has an error list with the 50 most recent errors. The pre-
defined error field (OD index 1003h) contains the number of error entries (OD
index 1003h/00h).
The other sub-indices contain the saved error states in chronological order with
the error occurred last being always found under the lowest sub-index (OD index
1003h/01h).
The oldest error is in the highest available sub-index and is the first to be removed
from the list in the case of more than 50 errors.
If an error occurs, a new error entry is added to the error field (OD index 1003h)
and also communicated via an EMCY message.
