3.11 Analog inputs
MX2 provides two analog inputs, the input terminal group includes the [L], [OI],
[O], and [H] terminals on the control connector, which provide for Voltage [O] or
Current [OI] input. All analog input signals must use the analog ground [L].
If you use either the voltage or current analog input, you must select one of them
using the logic input terminal function [AT] analog type. Refer to next table for
details about the combinations between A005 and [AT] terminal. Remember that
you must also set A001=01 to select analog input as the frequency source.
If [AT] function is not assigned to any digital input the inverter recognizes the
[AT] as OFF and [O]+[OI] will be used as analog input. In case either (O) or (OI)
is to be referred, please ground the other.
For [O] input and using parameters A013 and A014 you could select the portion of
the voltage input range. Parameters A011 and A012 select the start and end fre-
quency of the converted output frequency range, respectively. When the line does
not begin at the origin (A011 and A013 > 0), then A015 defines whether the
inverter outputs 0 Hz or the A011 specified frequency for analog input below A013.
