Diagram 5-12 Setting of three-line mode 1
As shown in the preceding figure, if SB1 is ON, the frequency inverter instructs forward rotation when Sb2 is pressed
to be ON, and instructs reverse rotation when SB3 is pressed to be ON. The frequency inverter stops immediately
after SB1 becomes OFF. During normal startup and running, SB1 must remain ON. The frequency inverter's running
state is determined by the final actions on SB1, SB2 and SB3.
3: Three-line mode 2
In this mode, DI3 is RUN enabled terminal. The RUN command is given by DI1 and the direction is decided by DI2.
The parameters are set as below:

Diagram 5-13 Setting of three-line mode 2
As shown in the preceding figure, if SB1 is ON, the frequency inverter starts running when SB2 is pressed to be ON;
the frequency inverter instructs forward rotation when K is OFF and instructs reverse rotation when K is ON. The
Frequency inverter stops immediately after SB1 becomes OFF. During normal startup and running, SB1 must remain
ON
，
SB2 is effective immediately after
ON action.
