Analog input and output parameter group 02
PARAMETER DESCRIPTION 125
Terminal 2-5 signal selection, maximum operation frequency
Set value of 02-09(P.38) is the target frequency value of inverter when terminal 2-5 input signal is 5V (10V).
Example 1: This example is the most commonly used adjustment method. It is used when inverter is in “external
mode", “combined mode 2”or “combined mode 4”, and frequency command is given by terminal 2-5.

Voltage
Terminal 2-5 can be connected to a negative voltage, but 02-08(
P.73
) value needs to be changed. The frequency
algorithm is same as positive voltage, and its running direction is unchanged.
Note: 1. In “External mode", “combined mode 2” or “combined mode 4”, the inverter target frequency will be determined
by signal between 3-5/2-5/4-5/HDI terminal if RH, RM, RL and REX are all “off.” (the default priority is
2-5>4-5>3-5>HDI, please refer to 02-00(P.500), 02-01(P.501), 02-02(P.504),02-03(P.503).
2.The functional names of RH, RM, RL, REX, AU, RT and RUN mentioned in this paragraph are "multi-function
digital input terminals". For the function selection and function of multi-function digital input terminal, please refer
to 03-00~03-09(P.80~P.84,P.86,P.126~P.128,P.550),03-25~03-30(P.551~P.556), 03-33~03-38(P.559~P.564);
Please refer to section 3.7 for wiring.
3. If
use 02-0803-00(P.83)~03-06(P.126), 03-09(P.550) to select 2-5 terminal voltage signal sampling range, it
will affect the relevant value in section 5.3.5 parameter group of the 2-5 terminal input signal.

input signal processing
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.
