Index: Example for P0757, applies also to parameters P0758 through P0760.
P0757[0]: IN000=Analog input 1.
P0757[1]: IN001=Analog input 2.
P0761, Width of deadband (V/mA) for analog inputs
P0761 defines the deadband for the analog inputs.
Setting range: 0 to 10V, or 0 to 20 mA
Factory setting: 0
NOTE: P0761[x] = 0: No enabled dead zone.
The dead zone runs from 0V (or 0 mA) to the value of P0761, if the values of P0758 and
P0760 (y-coordinate for analog input scaling) have the same sign. The dead zone is enabled
from the intersecting point (x-axis with analog input 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 deadband.
