– MOLLOM VFD 7.5KW 10HP 32A 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 used this on a 3 phase 10hp air compressor and using the pressure switch and a secondary switch to start and stop the unit. I sent the company a message with some questions and they replied right away with all the answers and more! Seems to be doing the job. Only downside compared to other units is where the wires tie in you have to ensure you secure your wires to keep them from pulling but other than that I don't see much of a difference between this one and others I have installed. I don't use even a quarter of the features though.

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.

This is going to power a 5hp motor for my lathe. I managed to screw up the programming, as these are a bit different than other Chinese VFD's I am familiar with. The rep got back to me and told me how to return it to factory default. Go to FP.00 and type in 18181, then set FP.01 to 2, that's it. motor setup is as below: F1-02 set the line in voltage F1-03 set the max amps F1-05 set the RPM F0-10 set 60 cycles maximum output F0-12 set the upper freq limit F1-04 set the rated frequency of motor F0-19 set accel/decelerate time in seconds F0-17 set acceleration time seconds F0-18 set deceleration seconds And these are the ones to set and you are done. The machine and fan are much quieter than the Teco and AC Lenz drives I have which is blessing.

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
