With these parameters, the definition of the gear stage is via the output of an S-analogue voltage. The highest
possible rpm (with S-override 100 %) is programmed for each gear stage. The gear stage with the lowest possible
rpm is programmed with parameter 78 etc. If less than 8 gear stages are programmed, the unused parameters
for gear stages are programmed with "0".
All parameters for gear stages are to be programmed with "0" if operation is with coded rpm output.

With these pa.rameters, the limitation for the S-override potentiometer is programmed (No. 88 maximum,
No. 89 minimum). After reaching the programmed limitation - either max. or min., the S-analogue voltage
remains constant.
