This function code defines four different ways to control the operation of the inverter through external terminals.
0: Two-wire control mode 1
Xm: Forward rotation command (FWD), Xn: Reverse rotation command (REV), Xm and Xn represent any two terminals of DI1-DI5 defined as FWD and REV
functions respectively. In this control mode, K1 and K2 can independently control the operation and direction of the inverter
Figure 02-1 Schematic diagram of two-wire control mode 1
1: Two-wire control mode 2
Xm: Forward rotation command (FWD), Xn: Reverse rotation command (REV), Xm and Xn represent any two terminals of DI1-DI5 defined as FWD and REV
functions respectively. In this control mode, K1 is the run and stop switch, and K2 is the direction switch.
Figure 2-2 Schematic diagram of two-wire control mode 2
2: Three-wire control mode 1
Xm: Forward rotation command (FWD), Xn: Reverse rotation command (REV), Xx: Stop command, Xm, Xn, Xx represent any 3 terminals of DI1-DI5 defined as
FWD, REV, and three-wire operation control functions respectively . Before K3 is connected, the connected K1 and K2 are invalid. When K3 is connected, K1 is
triggered, the inverter rotates forward; K2 is triggered, the inverter reverses; K3 is disconnected, the inverter stops.

3: Three-wire control mode 2
Xm: run command, Xn: run direction selection, Xx: stop command, Xm, Xn, Xx represent any 3 terminals of DI1-DI5 defined as FWD, REV, and three-wire
operation control functions. Before K3 is connected, the connected K1 and K2 are invalid. When K3 is connected, K1 is triggered, and the inverter rotates forward; K2 is
triggered separately, which is invalid; after K1 is triggered to run, K2 is triggered again to switch the running direction of the inverter; K3 is disconnected, and the inverter
stops.
