Several methods to control the frequency of VFD
1. Switch Button control
2. Analog control
3. Potentiometer control
4. Modbus-RTU control
5. DTU wireless remote control

1. Switch Button control
Use the switch signal to directly control the start and stop of the VFD (the VFD start frequency is fixed), and the multi-speed control method can be used to activate the speed of each section of the VFD.

2. Analog control
Use 5V or 0~20mA to control the frequency of the VFD, and at the same time can control the start and stop of the VFD in cooperation with the switch.

3. VFD potentiometer control
The VFD has its own potentiometer input terminal, and the VFD is directly controlled by the potentiometer.

4. Modbus-RTU control
Use RS485 interface to transmit data with Modbus-RTU protocol, which can monitor VFD, modify frequency, start and stop, etc.

5. DTU wireless remote control
Combine DTU terminal and VFD for wireless transmission (DTU output analog quantity to control VFD frequency)
