Tips: VFD motor protection

Do you need an overload to protect the motor? And if so do you put in on the PWM output side?
How should I protect the variable frequency drive and Motor?

Variable frequency driveVFD itself has many protection functions by working on variation of controlling voltage & current through open/close IGBT and detecting CT/ VT. Depend on size of VFD we can see on panel input/ output, DC voltage; input/ output current or can measure by tool; The basic function is overload protection by both setting normal 110% and trip 150% mode.

The variable frequency drive (VFD) can make the thermal protection. However you can also use a digital relay to make it. In that case the relay will be connected downstream the VFD. Such arrangement is used when one drive will control several motors. The only tricky point is that the frequency tracking in the relay shall use the current, whereas the usual technology is to use the voltage. But there exist relays using the current measurements for frequency tracking.

For the second question you need an upstream protection, which can be ultra-rapid fuses or circuit breaker with protection relay. Eventually, a good solution for LV VFD would be to add a line-choke upstream the VFD, this will reduce the current transients seen by the input of the VFD. In MV VFD there are usually input transformers for the VFD which realizes this function.

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)

I am looking for a bit of help

I am looking for a bit of help in setting up one of your VFDs to run off of our PLC system. In particular, the 7.5hp VFD model is linked here. I have looked at the documentation here, but I want to be sure I do everything right. Can you provide step-by-step instructions on this? As well as how to wire it for this configuration.

Please refer to the video on how to configure the VFD for control with a 0-10Vdc signal: https://www.youtube.com/watch?v=740KFfdA_M8&list=PLlo8RulDRnthB_yJeKHLcVVbUFz2r9ked&index=2

44/150 VDC input voltage, and output AC, 3-phase, 208V

Can our SKU: GK3000-SP1S1-5d5 work based on 144/150 VDC input voltage, and output AC, 3-phase, 208V?

From: Henry | Date: 23/11/2023

ATO Responded

Unfortunately, the input voltage of the GK3000-SP1S1-5d5 VFD can only be a maximum of 138VAC and can Not input 144/150VDC.

How does a VFD connect to a compressor?

I bought this VFD, in order to run my 3 phase air compresor 220v/35Amps, now I am wondering if I need a swift output filter to connect the compressor, or that is optional?

From: Daniel | Date: 27/05/2022

Was this review helpful? Yes No (0/0)

ATO Responded

That is optional, you could add an output filter or not. The VFD can only carry the motor of the compressor and cannot be used as a power supply.

Information about VFD

Is this VFD CSA approved? And what is the max amperage input, recommended breaker (2hp VFD 120V single phase input-220V 3 phase output)?

From: Wbender | Date: 27/05/2021

Was this review helpful? Yes No (0/0)

ATO Responded

1. CE approved only.
2. Input Current: 14A, breaker rating: not less than 20A.
