AC 220V/1.5kw 2HP Variable Frequency Drive,8A VFD Inverter Single Phase to 3 Phase Frequency Converter for Spindle Motor Speed Control(Single-Phase Input, 3 Phase Output)

I used the AT1-1500 2HP unit to power up a 1966 Bridgeport Series 1 1 HP mill. The motor was originally wired for 440 VAC 3-phase. I only had 220VAC 1-phase in my barn. I reconnected the motor leads for 220VAC. The unit worked flawlessly in converting 1-phase to 3-phase. I am an engineer and have installed many VFD drives. The instructions are somewhat difficult to understand. There several videos online that are helpful and the seller's tech team responded to emails within 1-2 days. There are a few things that the unit does not like. Most Bridgeports have a reversing drum switch mounted on the motor. My original intent was to power up the VFD with the run command at the same time. The VFD goes through a brief self diagnostic routine when it is first powered up. Calling for a run command at startup caused an Error 1 display. When I added a separate Off-Run switch, the unit functioned without error since there was an inherent delay between powering the VFD and switching it into run mode. Secondly, the unit did not work with the reversing drum switch. After switching the VFD to run, I actuated the drum switch and the unit tripped out on overload (Error 2). Positioning the drum switch in forward or reverse before commanding the VFD into run eliminated this. I removed the drum switch and replaced it with an aluminum junction box from Amazon. I changed the Off-Run switch to a 3-position Reverse-Off-Forward switch and wired it to terminals X4 and X5. The motor worked perfectly. I set the minimum Hertz (P07) to 60.0. Running an older, non-inverter duty motor at less than full RPM can cause it to overheat. A replacement motor is $1500. I am content to change the belt drive step pulleys. Lastly, because the AC sine wave current is generated by modulating pulses of DC current, a standard Amprobe meter will not read the correct input or output amperage. But, the motor amp draw can be displayed on the control unit.

great unit for the price! I used it for my 2x72 belt grinder and place this unit inside an ammo can to keep dust off it. Been in service for approx 1yr and still going strong. wiring was a breeze, buy with confidence!

Would recommend sizing up for horsepower personally. We have a 1 hp engine on our Bridgeport and after reading reviews went with a 2hp and very glad we did. Works well no errors for drawing power. I will say if you aren’t electrically inclined you may need some assistance with wiring. There isn't a hold your hand manual set up, be prepared to do a bit of homework or ask your neighbor that is an electrician for some guidance! Love the variable speed as we can go even slower than the original belt driven motor if needed. All in all, a great option and I would purchase again. *** rated tech support as 3 for neutral as we did not use tech support.

Got it working. Works so far. Would be cool to see videos on programming for even easier ease. Also, does anyone know what kind of remote controls work for this? It's probably just buttons into the external terminal and I just haven't learned it yet. Anyway, great product for the price.

Part arrived as promised. Haven't had time to install. Probably be another 6 weeks before my schedule opens up.

After installing and using this for many hours, and installing and using the more expensive black VFD: Spend a little more on the black one, it is worth it. Pros of the XCFDP: - Better manual than some other VFDs in terms of step by step programming directions - Works - The unit is programmed to the defaults shown in the manual Cons: - As alluded to in the ad in broken english, most of the "remote" functions that you will want to use to integrate the VFD into your tool are not implemented or not implemented correctly. Those that do work only work in a janky way or with additional electronics. - The programming may not be safe in terms of machine integration; some of the stop/start inputs will unexpectedly start or stop if repeatedly pressed, held in, etc. One of the weirdest is the E-stop when programmed to momentary normally open; it only stops when the contact is BROKEN. So even if you are using a momentary, push-button, non-locking, normally open switch, the machine only stops when you RELEASE the switch. - Related to above, there are references in the manual to features and options that just don't exist. None of these negatives are present in the slightly more expensive black VFD that is commonly available here on Amazon. The black one has many more features, all the features are present and work as expected, and it is documented better by third parties.

I found this product easy to set up and use for my wood lathe. I would definitely recommend this to anyone wanting a replacement for their VFD.

Used a 2hp for my 1hp disc sander. Had to go up a size as the 1hp didnt have enough oomph for moving something hi torque. Works great though amd easy to program.
