7.2.2.2 AN3 (An.20)
With An.20
it is determined from where the 3. analog input value is received. Following values can be defined:
An.20: AN3
Va-

Function
0 Analog option (AN3)
1 Analog input 1 (AN1)
7.2.3 Noise filter (An.01,
An.11, An.21)
The noise filters shall suppress disturbances and ripples of the input signals. If the noise filter is switched off the
analog inputs are queried every 1 ms and the recorded value is transferred then. The noise filter adjustments
preset the number of sampled values for the averaging.

7.2.4 Save mode (An.02, An.12, An.22)
Coming from the
input filter the save mode can be switched on with
An.02 / An.12 / An.22 . If now the pro-
grammable digital input (value 1) is set the analog signal is processed directly and written parallel into the non-
volatile memory. As soon as the digital input is disconnected (value 0), the inverter continuos to run with value
stored in the memory. Moreover, with An.02/ An.12/ An.22 it can be determined whether the memory contents
are saved or deleted upon switch off.
