Emergency Messages
If the encoder detects an internal error, then an emergency message is sent automati-
cally by the AHS/AHM36 CANopen and AHS/AHM36 CANopen Inox.
For this purpose a message is formed from the error code in the object 1003h
, the error register in the object 1001h
and the
Device Status Word in the object 2010h
