Warnings
Supported warnings (attribute 47+48)
Alarms
The alarm type is coded in a bit field of attributes 44 and 45. If one of the bits is
listed below is set, the alarm flag (attribute 47) will also be set.
If, for example, the velocity or temperature drop below/exceed the limit values,
the warning flag is set (attribute 49 position sensor object).
In addition, the Net LED flashes red.
The warning type is coded in a bit field of attributes 47 and 48.
Note: The position value will continue to be correctly calculated; the encoder is
therefore still ready for operation.
