7.2.13 Pr.40 = 13 , Speed input is the combination of AI2
±
( Pr.15 * (Pr.70*AI1) )
In this mode, the desired set frequency is the combination of AI1 and AI2.
Set Frequency = AI2
±
( Pr.15 * (Pr.70*AI1) )
Analog signal from AI2 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.

7.2.14 Pr.40 = 14 ~ 16, Reserved for factory use
7.2.17 Pr.40 = 17, Similar to mode 1, with minimum frequency = Pr.16
While the desired output frequency is lower than Pr.16
(LOWER LIMIT), the actual output frequency will maintain at
the lower frequency limit.
Note:
Set jumper JP1 to match with the input voltage range. If
necessary, use Pr.89 and Pr.90 to modify the input range.
