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.

Index:

P0761[0]: IN000=Analog input 1.

P0761[1]: IN001=Analog input 2.

Analog Outputs

SED2 converts status variables such as output

frequency, motor voltage, or present motor

current via D/A converters (DAC) within a

scaleable range. The analog outputs then

display their values.

NOTE: For accurate and consistent

performance of SED2 analog

outputs, if you are not connecting a

NI 1000 sensor then terminals 10

and 4 (NI 1000) must connect to

terminal 2 (0V).
