Tips: Variable Frequency Drive vs Soft Starter

If you need to vary the speed of the driven load, then a VFD is definitely the choice. If you are looking to reduce the starting current and the starting torque of an induction motor, then a soft starter can be selected.
If energy savings (reduced speed) is the issue a VFD will almost always be the first choice, but again the driven load, (VT) and application require review and sizing considerations. If speed control is the consideration then a constant torque load will require a VFD. The motor basics we have had to live with, NEMA design A, B, C & D are there for a reason as one design doesn't fit all applications. The controller is just another tool to use within it's limitations to provide the desired result for an application.
Soft starter - considerably cheaper than VFDs, much more efficient, does not require harmonic mitigation, but draws 3 - 4 times start current and does not offer variable speed feature. Understanding the application and exactly what you are trying to achieve would be the most important factor.

Running a Three-phase Motor on a Single-phase Supply with a Frequency Converter

How to run a three phase or single phase motor with ATO VFD on 120V power supply. Take a 2 hp, single phase 120V input, single phase or three phase 220V output variable frequency drive as an example. It shows you how to wire, set parameters, commissioning VFD, run motors, etc.

How Many VFD Control Methods Do You Know?

Several methods to control the frequency of VFD:

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)
