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”.
Spindle speeds above and below the pre-programmed rpm
If within an rpm range of a gear ratio a certain spindle speed is not reached or is exceeded, a marker M2504
can be set or reset as of software level 03.

log. state 1 comparator speed not reached
log. state 0 comparator speed exceeded
If this type of recognition is required, 4 gear ratios are available instead of 8.
Machine parameters
MP78 - MP81 Spindle speed for 4 gear ratios
MP82 - MP85 new function here, the comparator speeds are entered for the 4 gear ratios.
The comparator speed in MP82 is of course, smaller than the maximum speed of the gear ratio corresponding
to MP78 (override 100 %).
From this relationship the control is able to recognise if the display of a reduced or excessive speed is
required with M2504.
If the entry values of MP78 to MP85 are increasing values, 8 gear ratios are correspondingly programmed and
the described function is inactive.
