Warnings
Alarms
The alarm type is coded in a bit field of attributes 44 and 45. If one of the bits
listed below is set, the alarm flag (attribute 47) is also 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 status indicator blinks red.
The warning type is coded in a bit field of attributes 47 and 48.
Note: The position value continues to be correctly calculated; the encoder is
therefore still ready for operation.
