Drive object:
Each message (fault/alarm) specifies the control mode (CU-variant) in which it can be found.
A message can belong to one, several, or all CU -variants.
Reaction: Default fault reaction (adjustable fault reaction)
Specifies the default reaction in the event of a fault.
The optional parentheses indicate whether the default fault reactions can be changed and
which fault reactions can be adjusted via parameters (p2100, p2101).
Acknowledgment: Default acknowledgment (adjustable acknowledgment)
Specifies the default method of acknowledging faults after the cause has been eliminated.
The optional parentheses indicate whether the default acknowledgment can be changed and
which acknowledgment can be adjusted via parameters (p2126, p2127).
