Parameter Description Help text Possible settings Unit Factory setting
3-9-6 Dry Running Detection
3-9-6-1 Hydraulic Blockage Limit Factor for shifting the learning curve. The
limit curve for hydraulic blockage is
calculated based on the product of the
learning curve with the parameter.
0 … 130 % 110
3-9-6-2 Dry Run Time Limit Factor for shifting the learning curve. The
limit curve for dry running is calculated
based on the product of the learning curve
with the parameter.
0 … 130 % 85
3-9-6-3 Start Learning Function When the learning function is run, the
frequency inverter activates 5speed points
and saves the associated mechanical power
values. For this purpose, it must be ensured
that discharge-side valves are fully closed.
