For Frame 4 drives only (firmware version 2.x), the actual modes of the analog
inputs depend on the value of this parameter and on the capabilities of the analog
input hardware on the Combined I/O board. The units (V or mA) displayed for
the Analog In Hi and Analog In Lo parameters are an accurate indication of the
actual mode of the corresponding analog input if the input is physically present
on the Combined I/O board.
See AC Line I/O Board Description (Frame 3 Only)
on page 25 through
Combined I/O Board Description (Frame 4 Only)
on page 29 for a description
of I/O hardware that is present on this drive and is controlled by the inverter.
Enables/disables the square root function for each user-configurable analog
input.

This function should be enabled if the input signal varies with the square of the
quantity (for example, drive speed) being monitored. The square root function is
scaled such that the input range is the same as the output range. For example, if
the input is set up as a unipolar voltage input, then the input and output ranges of
the square root function are 0...10 volts.
