RATTMMOTOR Variable Frequency Drive 220V 3KW 4HP VFD Inverter Frequency Converter 400Hz 13A Single Phase Input, 3 Phase Output Cable for CNC Water-Cooled Air-Cooled Spindle Motor Speed Control

Muy bueno y funcional, tal y como en la foto y en Internet se puede encontrar cómo instalarlo y cómo programarlo

I used this inverter and some other parts from this seller, to make my own CNC machine. The instructions are pretty good, along with the 80 page manual. The seller is quickly responsive to questions and they know their product well. This is important if you are unsure about something.

1. The manual is not for the light hearted, you must have some intuition about these things. 2. Maybe can find it less expensive if you search. 3. It is a Huanyang made inverter. 4. Quality throughout. 5. Unlimited capabilities for the technically inclined. 6. Beautifully manages 3 phase motors to use for finer things. This is my third Huanyang VFD in the last several years; they have not faltered once. I'm staying with this brand.

Great Great well known branded 3 phase VFD for the money. Make sure you read the fine print only good for a 110 V. Excellent customer support responsive directly at their website.

Purchased this to run a 2.2kw water cooled spindle. worked great! Programming the VFD was easy and the manual was not overly complicated to understand. The Seller answered questions very quickly and I would purchase another one of these if I ever needed it.

These seem to work well, I use them because I needed to mount to the machine and wanted a inexspensive desposable unit.

There are so many variations of this cheap vfd. Most of them are similar but to make it clear I knew I was buying a cheap piece of equipment but I could get it here quick while I waited on a real vfd. To my surprise this one does not have an auto tune function at all. You can choose from 3 different curve profiles. This makes a few issues. One being the high frequency, nails on a chalkboard sound it makes when starting. The other is heat. Another annoying noise it makes is the cooling fan... you have to choose from a few profiles depending on torque curve you desire. More torch, more nails on chalkboard. I can hear it over my compressor! Again it’s cheap and will keep things moving while I wait for the real one. Don’t expect much. I’m running it on a cnc lathe spindle and was able to operate it using remote triggering and variable speed using 0-10V functions from my cnc.
