P1.4.3.4
321
AI1 custom minimum setting “AI1 custom min”
P1.4.3.5
322
AI1 custom maximum setting “AI1 custom max”
P1.4.4.4
326
AI2 custom minimum setting “AI2 custom min”
P1.4.4.5
327
AI2 custom maximum setting “AI2 custom max”
These parameters set the analog input signal for any input signal span within
-160...160%. E.g. if the signal input scaling is set to 40 %...80 % the reference can be
changed from 8 mA (for Minimum Frequency) to 16 mA (for Maximum Frequency).
P1.4.3.6
303
AI1 Reference scaling, minimum value “AI2 RefScale min”
P1.4.3.7
304
AI1 Reference scaling, maximum value “AI2 RefScale max”
P1.4.4.6
393
AI2 reference scaling, minimum value “AI2 RefScale min”
P1.4.4.7
394
AI2 reference scaling, maximum value “AI2 RefScale max”
Additional reference scaling. Analog input reference scaling can be set to a different
value than the minimum and maximum frequency.

The small values of the reference around zero can be ignored by setting this value
greater than zero. When the reference lays between zero and ± this parameter, it is
forced to zero.
