AC 220V/0.75kw 1HP Variable Frequency Drive, 5A VFD Inverter Single-Phase to Three-Phase Frequency Converter for Spindle Motor Speed Control

Take a chance, and take your time installing. The first one I received did not light up, so I was a bit concerned. But I have had good luck so far , so I opted for a replacement. The replacement came the same day and it did not fail to perform. I have been researching VFD programming for 3 phase machinery for a week. After changing every hertz value to 60, I powered up the spindle and watched it slowly creep into a full rotation speed and upwards to the fired speeds. The initial install is basic , I have not wired in my momentary switches for direction and stop. I will also add an external tach on the machine. But that is in the future. All in all it was worth buying, my machine is only running a 3/4 hp 3 phase motor. I will eventually need something bigger , but for now this is great! Compared to the sounds of machinery I think the VFD is quiet

Purchased this for my recent purchase of a 3 phase wood lathe. Was easy to install and is working fine so far. Haven't used it much yet so don't know about the reliability of it yet. Time will tell.

Easy to wire and program. Works as advertised.

Like the title suggets?, What am i missiin here:1. I turn on the device for the first time and i do a factory reset so i can configure all from scratch. Since is the first time i turn on the device i can test everything, the potentiometer is the default one to be used. BUT after i turn off the device and later plug it in again, the pontentiometer max is 19 hz, no matter what parameters i configure, i'm on america so 60 hz in my case. I have to increase / decrease the hz using the buttons and i can go from zero to 60 hz and viceversa without problem, but when it comes to the pontetiometer i cant go further than 20 hz. ALSOOOOOOOOOO, the second unit i bought happened the same think. The first time i turn it on i can use the pontentiometer fully with no issues, the problem starts when i cut the power and later turn it back on again, and same thing, it doesnt go more than 20 hz. DEFINETIVELY the deveces is doing something its not suppose to do.2. Both devices too, the brake time, it is by default 2.5 seconds, and i reduce to use example 1 second, it doesnt do anything, i configure the parameter to use the brake time and later configure the time of the brake, its always the same 2.5 s, and yes, im using the brake stop mode on P12 with the value of 2.If i use the Intertial stop it works, if i use the inertial stop i suppose it works because it stops at 2.5 seconds, and if i use the Emergency brake, it stops right away, fully stop. But if i want to use the BRake stop so i can configure how much time i want to stop from fully speed to 1 second it doesnt do any change, its on 2.5 s default.What am i missing here.?

Works great

THE GOOD:- It worked when powered up!- The parameters were preset pretty decently for my drill press.- It is a simple VFD with few settings to worry about but still has the basic features needed.- Far less expensive than big name VFDs.THE BAD:- It is not safe for facemounting without a box/enclosure. This was a big deal for me. I was working with 10 AWG SOOW and my older unit (a Delta) was set up to accomodate with appropriate cable clamps meeting code so the individual conductors were enclosed at all points where the outer jacket was stripped. In order to safely fixt this problem, I had to mount the VFD inside of a UL listed electrical enclosure.- The wire terminals were too small for the appropriately sized conductors. Could I get #10 wire in place? Yes, but it was a job. The terminals have a wire clamp similar to what might be found on a NEMA plug, but it was VERY difficult to get the wire into the clamp without a terminal end. As others noted, the terminals are not big enough to accomdate a forkl terminal much less a ring. I ended up stripping the jacket and soldering the tightlest twisted conductors so no loose strands would create an opportunity for arc or short.THE UGLY:- I remain apprehensive given the comments others have made about the unit failing soon after installation. Only time will tell but it would be nice to have a little confidence in the product.

Haven't had a chance to power it up yet but it is very frustrating to find out upon installation that the terminals for input and output power do not accept #10 AWG fork crimp style terminals. It is possible to barely slide a 14-16 AWG crimp terminal in there but this makes it very difficult to create a well made crimped connection onto the wire.

I'm using this for a belt grinder.I thought it had fried one day. Saw a big spark at the control box and blew the breaker in my panel. But, it was my own fault. Either the wall switch or the control box got some grinding dust in it and that's what caused the problem. I reset the breaker and all was well. I then got a bit wiser and put a ziplock over the top of the switch and the panel to keep grinding dust away from them. It's been working flawlessly for 4 or 5 months now.Point is, the VFD is great. I'm running a 1.5HP 220v Hallmark 1800 RPM motor. I over-speed the motor by 50% (90 on the frequency dial) to get 2700 RPM. Supposedly, I should be able to turn it up to 120 or even 130...but I'm pretty happy where it's set now.FYI, I don't think I had to change any settings to initially run with a frequency cap of 60. So, very easy to set up.The wiring space is a bit limited. MY tip is: Don't use wirenuts - use WAGO connectors. They fit much more easily.
