P3.5.4.1.4 AO1 minimum scale
P3.5.4.1.5 AO1 maximum scale
These parameters can be used to freely adjust the
analogue output signal scaling. The scale is defined
in process units and it depends on the selection of
parameter P3.5.4.1.1.
Example: The drive's output frequency is selected for
the content of the analogue output signal and
parameters P3.5.4.1.4 and P3.5.4.1.5 are set to 10…
40 Hz.
When the drive's output frequency changes between
10 and 40 Hz the analogue output signal changes
between 0…20 mA.
