9.1.4 Attribute12, Direction Counting Toggle
Danger of death, severe personal injury and/or material damage due to a
jump in the absolute value when changing the counting direction function!

The internal calculation algorithm results in different absolute positions
for the counting direction settings ascending and descending
. Verify
the correct function by a test run in safe mode after changing th
e
counting direction. Under certain circumstances, the output position
must be adjusted via the preset function.
