Description:
Those parameters define the behavior of the frequency input according to the equation:
FI =
x (100 %) + P0249 x P0247
FI(Hz) – P0248
P0250 – P0248

Parameters P0248 and P0250 determine the operation range of the frequency input(FI), while parameters
P0249 and P0247 determine the offset and gain, respectively. For example, FI = 5000 Hz, P0248 = 10 Hz,
P0250 = 10000 Hz, P0249 = -70.0 % and P0247 = 1.000, thus:
FI =
x (100 %) – 70 % x 1.000 = 20.05 %
5000 – 10
10000 – 10

The value FI = -20.05 % means that the motor will spin in the opposite direction with a reference in module
equal to 20.0 % of P0134.
When P0246 = 1, the digital input DI2 is pre-defined for frequency input, regardless the value of P0264, with
operating capacity in the band from 10 to 20.000 Hz in 10 Vpp.
The time constant of the digital filter for the frequency input is shared with the analog input AI3 through parameter
P0245.
12.4 FREQUENCY OUTPUT
Like the frequency input is implemented in the digital input DI2, the frequency output is fixed to the transistor
digital output DO2.
The configuration and resources available in the frequency output are basically the same as those of analog
outputs, as shown in
