P248
Digital input DI3 is pre-defined for frequency input with operating capacity in a wide band from 1 to 3000 Hz.
P022 – Value of Frequency Input
Adjustable 1 to 3000 Hz
Range:
Properties: ro
Description:
Value in hertz of the frequency input FI.
NOTE!
The operation of parameters P022 as well as of the frequency input, depends on the activation of
P246.
P245 – Filter of the Frequency Input
Adjustable 0.00 to 16.00 s
Range:
Properties:
Description:
This parameter sets the time constant of the Frequency Input filter. It is intended to attenuate sudden changes
in its value.
P246 – Frequency Input FI
Adjustable 0 = Inactive
Range: 1 = Active
Properties: cfg
Description:
When set to "1", this parameter activates the frequency input, making the function of the digital input DI3 in
P265 be ignored, as well as the value of bit "2" of P012 is maintained in "0". On the other hand, when set to "0",
the frequency input is inactive, keeping parameter P022 in zero.
