7.2.22 Pr.40=22, Set frequency = Panel set frequency
±
( Pr.15 * (Pr.70*AI1) )
This mode is similar to mode-13; however, Panel-Set Frequency is used instead of AI2 input.
In this mode, the desired set frequency is the combination of Panel input and AI1.
Set Frequency = Panel-Set
±
( Pr.15 * (Pr.70*AI1) )
Frequency command for Panel (or computer) is selected to be the major set frequency; and signal from AI1 is the
auxiliary input.
If signal level of AI1 is maximum, the modification quantity is (Pr.15 * Pr.70);
And if AI1 is minimum, the modification quantity is -(Pr.15 * Pr.70).
Note: Minimum-running frequency is Pr.16.
This function is useful when master computer controls multiple inverters.

7.2.25 Pr.40=25, AI3 use as frequency source (Similar to mode 2)
This mode is similar to mode2, but AI3 is used instead of AI2. Pr.91 and Pr.92 are used to define the high and low limit
of AI3. Input range is 0~+5V.
7.2.26 Pr.40=26, AI3 used as bi-directional frequency source (Similar to mode 5)
This mode is similar to mode5, but AI3 is used instead of AI2. Pr.91 and Pr.92 are used to define the high and low limit
of AI3. Input range is 0~+5V.
7.2.27 Pr.40=27, AI3 used as bi-directional frequency source with minimum speed
This mode is similar to mode10, but AI3 is used instead of AI2. Pr.91 and Pr.92 are used to define the high and low
limit of AI3. Input range is 0~+5V.
7.2.28 Pr.40=28 , Speed input is the combination of AI1 * ( 100%
±
(Pr.70*AI3) )
This mode is similar to mode12, but AI3 is used instead of AI2. Pr.91 and Pr.92 are used to define the high and low
limit of AI3. Input range is 0~+5V.
7.2.29 Pr.40=29 , Speed input is the combination of AI3
±
( Pr.15 * (Pr.70*AI1) )
This mode is similar to mode13, but AI3 is used instead of AI2. Pr.91 and Pr.92 are used to define the high and low
limit of AI3. Input range is 0~+5V.
7.2.30 Pr.40=30, Use AI3 as speed source, with minimum frequency = Pr.16
This mode is similar to mode18, but AI3 is used instead of AI2. Pr.91 and Pr.92 are used to define the high and low
limit of AI3. Input range is 0~+5V.
7.2.31 Pr.40=31, AI3 input, with Reverse Slope
This mode is similar to mode20, but AI3 is used instead of AI2. Pr.91 and Pr.92 are used to define the high and low
limit of AI3. Input range is 0~+5V.
7.2.32 Pr.40=32, AI1 input, with Reverse Slope
This mode is similar to mode20, but AI1 is used instead of AI2. In
this mode, the voltage signal fed into AI1 terminal will be used to
determine the output frequency of the inverter while running.
The direction of the output phase sequence must be determined by
control command.
If the input signal reaches maximum level, the set frequency is
equal to Pr.16 (LOWER LIMIT).
On the contrary, if the input signal is zero, the set frequency is
equal to Pr.15 (UPPER LIMIT).
Note: Set jumper JP1 to match with the input signal type and
range. If necessary, use Pr.89 and Pr.90 to modify the input
range.
