The inverter provides storage parameters for up to
16 different target frequencies (speeds) that the
motor output uses for steady-state run condition.
These speeds are accessible through programming
four of the intelligent terminals as binary-encoded
inputs CF1 to CF4 per the table below. These can
be any of the five inputs, and in any order. You can
use fewer inputs if you need eight or less speeds.
Note: When choosing a subset of speeds to use,
always start at the top of the table, and with the
least-significant bit: CF1, CF2, etc.
The figure below shows how input switches config-
ured with CF1 functions can change the motor
speed in real time.
