MOLLOM VFD 220V 7.5KW 32A 10HP Single or Three Phase Input to 3 Phase 0-3000 Hz Output Variable Frequency Drive Control Inverter for Spindle Motor CNC Speed Control

Language barriers always persist & this is no exception. A combination between really reclusive ee engineers & their cryptic manuals & the over use of hieroglyphic icons make comprehension very difficult for even dedicated DIY. Add to it Chinese conversion to english syntax & you'll feel like your on a river in a canoe with no paddle. The saving element is "Jeff". Not sure if this one person or a crew but he/they are completely commited to providing any & all answers in the shortest response time I've ever experienced. It's for that specific reason, I'll buy another VFD from them again & again. I'm not a potential customer for an $1100 VFD from Schneider or Eaton. If that were my only choices, I never would have bought the old metal lathe in the first place. So Mollom is fill a void in the market & there's no need to compare them to the mfg. I mentioned above, that was never Mollom's goal, this is a product for a different market audience not an alternative to the same audience.

I've got lots of VFDs. Recently one of them powering an older 5 hp Oliver table saw starting erratically not working at my ranch shop. I assumed it was a Mollom and emailed Jeff at Mollom about it. He immediately offered to replace it. When I actually checked the machine, it was NOT a Mollom, lol. So, I just ordered a new VFD for the saw, and replaced the big name VFD that was on it with a Mollom. Because of Jeff and Mollom's absolute standing behind their VFD's, I always try to buy them. Yeah, I could technically have gotten away with something smaller than a 7.5 KW for 5 hp. But I know the reason for the other failure, (jeff opined that it was a capacitor problem) was overloading the VFD when bogging down on a cut (The saw can run a 16" blade). We all know that Mollom doesn't have great manuals. But the Devices work very well and the service is impeccable. Any problems or questions, they answer the same day.

Product quit working in 4 months i had purchased a assurion insurance plan and have had nothing but issues it is a constant cycle of them sending me to amazon and amazon sending me to assurion terrible customer service

I bought this unit to replace an old and expensive VFD by MagneTek that was no longer manufactured. The MagneTek GPD 503 Model DS309 was going to cost over $1000 to possibly repair it and cost over $3000 new if you could find one. So I thought I would try this unit. Before purchasing this unit I sent a request to the seller with some technical questions and he responded in less than a day. After purchasing and receiving the recommended unit (model VFD 220V 7.5KW 32A 10HP) I asked for configuration information for my motor (230 VAC, three phase, 19.2 amps, 1755 RPM MagneTek motor in a commercial boiler system) and within less than a day got a response back from technical support with exact parameters for my motor. I connected it up and it worked, but the motor was noisy. Another message to support was quickly answered with the suggestion to increase the carrier frequency. I did so and the noise was dramatically reduced. (I increased the carrier frequency from the default of 4 kHz to 8 kHz using F0-15.) I then asked about terminal control of speed and quickly received a reply. Overall PROS: - excellent price/value - lots of configuration options for any application - flexibility - dual display - outstanding customer support CONS: - no UL or CE listing marks - no cable/conduit management knockouts (I needed to cut a hole in the top to route control cables cleanly) - cooling fan runs full speed whenever the motor is engaged...noisy and make me wonder how long it will last. - requires time to get all options understood and set up, but support is very helpful.

I had hopes that it would work fine for my old saw. The sawneede to be cleaned up so I sanded and painted it and bought the VFD. There was a lot to do so it took about a month. I checked the wiring on the saw, it was really good then I started mounting the drive. Apparently there wasn't a manual sent with it so I searched for it, that took a week but it didn't have the info I needed, other than how to wire it. Finally emailed the right person and got the correct parameters. So I tried it, very disappointed. We've been emailing back and forth for 2 weeks. I work a lot so it's now been 3 months since I ordered it. Now it looks like a faulty VFD. If they fix the problem I will update with a little higher review. Update: the new one works fine. It took a while but at least it's working.

This the 4th one of these we have purchased over the last few years. As of today we’ve had no problems with any of them or the machinery they service Easy to install Had a question regarding wiring with a braking resistor. Sent an email to support which was answered within 12 hours explains exactly what I had to do to achieve what we needed So far so good……Would buy again

Used this to run a 80 gallon Ingersoll Rand air compressor with a 5hp motor that is for 3 phase power installed it and wired it up pretty easy struggled a bit on the parameters but contacted customer service and sent them a photo of the tag on the motor and they sent me back what needed to be set up on the parameters. They responded fairly quick as well awesome customer service

We purchased this drive 3 different times and in all of them the product was not working fine. Go for American Made products for good quality.
