Then, the output variable follows the setcharacteristic.14.1.2.3 Filter Time ConstantThe time constant of the filter for the analog reference value can be set via the parameterFilter Time Constant 451.The time constant indicates the time during which the input signal is averaged bymeans of a low pass filter, e.g. in order to eliminate fault effects.The setting range is between 0 ms and 5000 ms in 15 steps.Operation mode0 - Time Constant 0 ms2 - Time Constant 2 ms4 - Time Constant 4 ms8 - Time Constant 8 ms16 - Time Constant 16 ms32 - Time Constant 32 ms64 - Time Constant 64 ms128 - Time Constant 128 ms256 - Time Constant 256 ms512 - Time Constant 512 ms1000 - Time Constant 1000 ms2000 - Time Constant 2000 ms3000 - Time Constant 3000 ms4000 - Time Constant 4000 ms5000 - Time Constant 5000 msFunctionFilter deactivated – analog reference value is forwardedunfilteredFilter activated – averaging of the input signal viathe set value of the filter time constants02/06 119
