The factory setting of the input scaling corresponds to 0 V = 0% and 10 V = 100%.
P0761
Defines the ADC dead zone for the analog inputs.

Note: P0761[x] = 0: No enabled dead zone.
The dead zone runs from 0 V(mA) to the value of P0761, if the values of P0758 and
P0760 (y-coordinate for ADC scaling) have the same sign. The dead zone is enabled
from the intersecting point (x-axis with ADC scaling curve) in both directions, if P0758
and P0760 have different signs.
When using a configuration with neutral point in the center, Fmin (P1080) should be
zero. There is no hysteresis at the end of the dead zone.
P0762
Defines the delay time in ms between the drop-off of the analog setpoint and the
display of error message F0080.
Setting range:
0 to 10,000 ms
Factory setting:
1000 ms
