Terminal command mode
Range:0
～
3
Default: 0
This parameter is used to set the mode in which the AC drive is controlled by external terminals.
The following uses DI1, DI2 and DI3 among DI1 to DI7 as an example, with allocating functions of DI1,
DI2 and DI3 by setting F4-00 to F4-02.
0: Two-line mode 1
It is the most commonly used two-line mode, in which the forward/reverse rotation of the motor is
decided by DI1 and DI2. The parameters are set as below:

Figure 6-8 setting of two-line mode 1
As shown in the preceding figure, when only K1 is ON, the AC drive instructs forward rotation.
When only K2 is ON, the AC drive instructs reverse rotation. When K1 and K2 are ON & OFF
simultaneously, the AC drives stops.
1: Two-line mode 2
In this mode, DI1 is RUN enabled terminal, and DI2 determines the running direction.

Figure 6-9 setting of two-line mode 2
As shown in the preceding figure, if K1 is ON, the AC drive instructs forward rotation when K2 is
OFF, and instructs reverse rotation when K2 is ON. If K1 is OFF, the AC drives stops.
2: Three-line mode 1
In this mode, DI3 is RUN enabled terminal, and the direction is decided by DI1 and DI2.
