1029 AUTOCHANGE INTERVAL 7 (2.9.26)
When this time is over, the autochange occurs if the capacity is below the level set with
parameters ID1031 (Autochange frequency limit) and ID1030 (Maximum number of auxiliary
drives). Should the capacity exceed the value of ID1031, the autochange will not take place
before the capacity goes below this limit.
The time count is activated only if the Start/Stop request is active.
The time count is reset after the autochange has taken place.
See Chapter 1031 Autochange frequency limit 7 (2.9.28).
1030 MAXIMUM NUMBER OF AUXILIARY DRIVES 7 (2.9.27)
1031 AUTOCHANGE FREQUENCY LIMIT 7 (2.9.28)

autochange can take place.
This level is defined as follows:
