The inverter can store up to 16

different target frequencies (speeds)

steady-state

programming seven of the intelligent

terminals as bit-encoded inputs SF1 to

SF7 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.

Valid for inputs:

Required settings

 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

configured for SF1–SF7 functions can

change the motor speed in real time.
