Two-wire control 1
The operation is in one direction. This mode is the most commonly used two-wire mode. The factory default is to determine the forward and reverse running of the
motor by the X1 (forward running) and X2 (reverse running) terminal commands. As shown below:

：
Two-wire control 2
The operation is separated from the direction. The forward running terminal X1 (forward running) defined in this mode is the operation enable terminal. The definition
of the direction is determined by the state of the reverse running terminal X2 (reverse running). As shown below:

Three-wire control 1
In this mode, the three-wire operation control terminal (Xi) is the stop operation terminal, and the running command is generated by the forward rotation operation terminal
X1 (forward rotation operation), and the direction is controlled by the reverse rotation operation terminal X2 (reverse rotation operation). The three-wire operation control
terminal (Xi) is an effective input.

Three-wire control 2
In this mode, the three-wire operation control terminal (Xi) is the stop operation terminal, and the operation command is generated by the forward rotation operation
terminal X1 (forward rotation operation) or the reverse rotation operation terminal X2 (reverse rotation operation), and both control the running direction.
