Three-wires mode 2
The DI terminal FWD is used to start the motor by pulse, DI terminal REV is used to control the motor
direction, DI terminal DI1 is used to stop the motor. The function can be achieved by wiring and
parameters set as below.
5.2.2. Target Speed Set

In remote mode, both analogue input AI1 and bus communication are default for speed set. By
applying an 0 ~ 10V on terminal AI1 and/or controlling command from the bus communication
can adjust the speed set. Please refer to the appendix A for more details about bus
communication control.

Use pulse input for speed set: Define the main speed set source as pulse input (P0-11 = 5), and
define the terminal function of DI4 to pulse input (P2-10 = 40), then you can adjust the speed
set by applying different frequency of pulse on DI4. Using pulse input for speed set has the
advantages of good accuracy and robust to EMC noise.

Multi preset value control by DI terminal function.In some application, the motor only needs to
run at several fixed speed. You can use DI terminal function to control the motor speed at
different preset value. Below is an example of 16 preset speed controlled by 4 DI terminals.
