JT550 Series Inverter Manual
1: Two-line mode 2
In this mode, DI1 is RUN enabled terminal, and DI2 determines the running direction.
K1
As shown in the preceding Figure , if K1 is ON, the inverter instructs forward rotation when K2 is OFF, and
instructs reverse rotation when K2 is ON. If K1 is OFF, the inverter stops.
2: Three-line mode 1
In this mode, X3 is RUN enabled terminal, and the direction is decided by X1 and X2.

3: Three-line mode 2
In this mode, X3 is RUN enabled terminal. The RUN command is given by X1 and the direction is
decided by X2.
F2.12 Terminal UP/DOWN rate
It is used to adjust the rate of change of frequency when the frequency is adjusted by means of terminal
UP/DOWN.
F2.13
F2.14
F2.15
Definition analog input terminal AI1, AI2 and keyboard potentiometer filter time, the input signal
filtering. Long filtering time, the anti-interference ability, but the slow response; filtering the fast response
time is short, but weak anti-interference ability.
F2.16 AI curve 1 minimum input
Corresponding setting of AI
F2.17
curve 1 minimum input
F2.18 AI curve 1 maximum input
Corresponding setting of AI
F2.19
curve 1 maximum input
These parameters are used to define the relationship between the analog input voltage and the
corresponding setting. When the analog input voltage exceeds the maximum value (F2.16), the maximum
value is used. When the analog input voltage is less than the minimum value (F2.18), the value set in F2.34
(Setting for AI less than minimum input) is used.
