The drive scales the value read from the user-configurable analog input and
converts it to units usable for the application. You control the scaling by setting
parameters that associate a low and high point in the input range with a low and
high point in the target range.
Analog In 1 Hi sets the highest input value to the user-configurable analog input
1 scaling block. 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.

Analog Input Scaling Example
Assume:
Speed Ref A Sel = Analog In 1
Minimum Freq = 0 Hz
Maximum Freq = 60 Hz
Analog In 1 Lo = 0.0V
Analog In 1 Hi = 10.0V
This is the default setting, where minimum input (0V) represents Minimum
Speed and maximum input (10V) represents Maximum Speed.
