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.
VFD Programming for Stable Water Pressure in Water Supply System
A three-phase motor can be regulated using a single-phase 120V to three-phase 220V VFD, and control can be managed through terminals, as demonstrated in the following video.
Variable Frequency Drive Setting
In the video, it's demonstrated that ATO VFD offers multiple methods to adjust the frequency: Not only can you use the knob on the panel, but you can also utilize the buttons for adjustments.
Basic Troubleshooting Guide for VFD
In this video, ATO will show you the vfd basic troubleshooting guide.
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)
