The interference suppression filters shall suppress disturbances and ripples of the
input signals. If the interference suppression filter is switched off the analog inputs are
queried every 1 ms (control card BASIC 2 ms) and the recorded value is then transfer-
red. With the interference suppression filters the inputs can now be queried 2-, 4-, 8- or
16-times. From these values an average value is determined which is then transferred.
An.1 / 11 / 21 Function
0 no averaging (default)
1 averaging over 2 values
2 averaging over 4 values
3 averaging over 8 values
4 averaging over 16 values
Coming from the input filter the save mode can be switched on with An.2 / An.12 /
An.22. If now the programmable digital input (value 1) is set the analog signal is
processed directly and written parallel into the nonvolatile memory. As soon as the
digital input is disconnected (value 0), the inverter continous to run with value stored
in the memory. Moreover, with An.2 / An.12 / An.22 it can be determined whether the
memory contents are saved or deleted upon switch off. The parameter is bit-coded,
the sum of the decimal values must be entered.

With An.3 / 13 / 23 the digital inputs for storing are selected according to the table on
the next page (also see Chapter 6.3.11 ÑAssignment of inputsì). In order to save an
analog value, the save mode (An.2 / 12 / 22 = 1) must be switched on under An2 / 12
/ 22 and the selected input must be activated.
