can be any of the six inputs, and in
any order. You can use fewer inputs if
you need eight or fewer speeds.

Notes:
• When programming the multi-speed settings, be
sure to press the SET 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

The example with eight speeds in the
figure below shows how input switches
configured for SF1–SF7 functions can
change the motor speed in real time.
NOTE: Speed 0 depends on
parameter value.

ON Makes multistage speed by combination of the
inputs.
