
The setting value of 02-21 (P.39) is the target frequency value of the inverter when the input signal of terminal 3-5
is at 20mA (5V/10V).


Parameters above define the relationship between analog input voltage and set value in analog input. When
analog input voltage exceeds maximum or minimum range of the set value, the excess part will be calculated as
maximum and minimum input.

There are two setting steps when setting maximum and minimum percentage:
1) If users want to adjust the analog input to correspond with a certain type of proportional relationship, Adjust
the analog input first and then set the corresponding proportional parameter. Inverter will calculate it by itself,
don’t need to set the voltage parameter (refer to Example 1.1).
2) If users skip the adjustment of analog input and set proportional relationship directly, first set proportional
parameter then set voltage parameters (refer to Example 1.2).
Example 1.1: User adjusts analog input voltage to minimum value A and sets parameter 02-27(P.196) adjusts
input voltage to maximum value B, and sets parameter 02-28(P.197) . As shown below:
