Multi-Speed Select
The inverter can store up to 16 different target
frequencies (speeds) that the motor output uses for
steady-state
accessible through programming five of the intelligent
terminals as binary-encoded inputs CF1 to CF4 per
the table to the right. These can be any of the six
inputs, and in any order. You can use fewer inputs if
you need eight or fewer 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.

Notes:
When programming the multi-speed settings, be
sure to press the Store key each time and then
set the next multi-speed setting. Note that when
the key is not pressed, no data will be set.
When a multi-speed setting more than 50Hz
(60Hz) is to be set, it is necessary to program the
maximum frequency A004 high enough to allow
that speed
run
condition.

configured for CF1–CF3 functions can
change the motor speed in real time.
