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.

These parameters are used to set the valid mode of DI terminals.
0: Low level valid
The DI terminal is invalid when being connected with COM, and valid when being disconnected from COM.
1: High level valid
The DI terminal is valid when being connected with COM, and invalid when being disconnected from COM.
