MOLLOM VFD 220V 2.2KW 3HP 9.6A 220V Single or Three Phase Input to 3 Phase 0-3000 Hz Output Variable Frequency Drive Control Inverter for Spindle Motor CNC Speed Control

I own three of these VFDs, and they have had 0 issues. The manual isn't bad at all, either. I was able to program this and understand the advanced settings very easily. Look, I'm not even running any circuit protection yet, and they work Flawlessly. I couldn't recommend the Mollom VFDs enough. Their price point and quality are spot on. I am not doing production work, I have a hobby shop with larger equipment.!

I have an exhaust fan in our manufacturing facility in very warm environment. Operating it with garage doors closed during cold temperature condition it causing a negative pressure resulting hard to open access doors. Running it with garage door open creates uneven temperature in different areas causing feuds among workers. I have ordered this inverter thru Amazon, inexpensive, which came in two days and installed in 20 minutes and it worked like champs! Easy to control speed with turning knob that worker adjust themselves with out any difficulty. NO MORE FIGHT! Installing and operating instruction were easy to understand. But I do not not know the durability yet.

Works amazing to control fan control speed on my commercial oven. Saved me alot of money. For installing find someone that understands these. Not a DIY thing.

I'm running a big 3 ph power saw. It wired in easily and so far has worked good. I have a different brand vfd on a different piece of equipment, and this one is a little louder. I think the fans running at a higher rate on the new one. Overheating has been a problem with the other, so I think it will cool better. So far I hav about 5 hours of run tim with no problems.

I bought this to upgrade my 6x26 knee mill to 3 phase so I could get variable speeds without have to change belt positions on pulleys. The vfd is easy to wire from 220 single phase to 220 3 phase output. This vfd has sensorless vector control, which a lot of others in this price range did not. This feature better controls the motors torque from what I understand. The manual is written pretty good considering. But I have still had to do a lot research to get the parameters adjusted. All in all, I think it is a good vfd for the money. I would buy it again. I might also note that I sent a message to their customer service and they were very prompt with a response.

For the price, this is amazing. I initially had it set up with the included remote panel, but now have a variable resistor for speed and push buttons for forward and reverse. Running a 2hp lathe. Great fine control once I got the settings dialed in.

The VFD looks nice, it has a nicer control panel and better internals than the common huanyang vfd. It will run your spindle. But unfortunately you'll get no support for it for questions. The seller will respond and only refer you back to this listing for details. I had several questions go unanswered. Should I derate the unit for single phase? How do I get RS485 ModBus to work, the basic parameter for baud rate is absent (perhaps the undocumented register Fd-00 but who knows what the default value of 5005 means). Do I set F1-00 for a spindle? In the end I could only get it to work under manual control and then with only about 1/2 the range on the potentiometer if you set a minimum frequency. I couldn't find any way to show RPM instead of frequency. The first one I got was a bad return, someone had smoked it. I looked inside and saw burned out power resistors and I also noticed Mollum do the same hack as huanyang and lay solder over some traces that must be undersized. In all its one of the cheapest VFDs but not worth your time. You can get a supported VFD for a little more. Even the huanyang has much better community support.

Excellent price point for a 2hp VFD. I have used Lenze Tech in the past and this seems to work as well out of the box. The MFG was super responsive to questions. I was emailing them @ 10pm est and getting a reply in minutes. Granted 10 pm here is 10am there. Still great responce time. There was some confusion between the chinglish manual and the markings on the terminal, but again I got clarification in minutes. I had inferred correctly, but it was nice to have that formal clarification. It was regarding single phase input. The manual calls out L & N and a ground symbol at the terminals for power & ground in but they were marked L1 and L2 and the ground terminal did not have a ground symbol but PE label. Programming was typically convoluted, but the manual was accurate. So, adjusting the max Hz to 60 for USA power grid and reducing the ramp up/dn to something reasonable for a drill press was a snap. If it doesn't blow up in short order it's a win.

Preço qualidade bom, atenção ao aterramento dos cabos analógicos e digitais para aplicações complexas. Para aplicações normais não há nada a apontar

The product is working great. I would like to know if its possible to connect remotely the keypad using a specific cable . Please contact me. Anything else the drive is working great with my motor. Easier to program than an altivar and a powerflex honestly

Qe esta bien

Muy sencillo de udar

Works well. Relatively easy to program. Could not program for a open circuit E stop switch.
