In this state, STO is active.
Alarm value (r2124, interpret decimal):
1: Wait for communication to be established with SINUMERIK.
If the message is not automatically withdrawn after a longer period of
time, then depending on the communication, the following checks
should be made:
For communication with SINUMERIK, the following applies:
-- Check and remove any additional messages that are present
regarding PROFIBUS communication.
-- Check the correct assignment of the axes on the higher--level
control to the drives in the drive unit.

IMMEDIATELY (POWER ON)
The stop position saved before powering--down does not coincide with
the actual position that is determined when powering--up.
Message value (r9749, interpret as decimal):
1: Axis not referenced
2: User agreement missing
If the axis cannot be automatically and safely referenced, then the user
must enter a user agreement for the new position using the appropriate
softkey. This therefore designates this position as being a safety--
related position.
