Attenuation of network interferences

Signal frequency, network interference 1:Fig.146: Index 0x8000:0A, Frequency

The Frequency function (CoE Index 0x8000:0A) can be used to reduce interference on the input signal from the mains. Depending on the location, either the 50 or 60 Hz setting must be selected; it cannot be switched off. The 50 Hz setting should be used for all other (existing or suspected) interference frequencies, as the integration time is then longer. It leads to an internal ADC integration time of 20 ms (setting 50 Hz) or 16 2/3 ms (setting 60 Hz), after which the measured value is available for further processing.
