Id honestly think thats a chinglish translation/mistake but fair enough, that is what it says!
So, do not cut input or output of the vfd. If you want an E stop, do it by the vfd controls (which probably dont have a suitable input for that..)
EStop coasts to a halt and needs resetting on the vfd panel when trigged.
Controlled stop is also available with alterable ramp down times.
Both available in the multifunction inputs.
Yes I have one powering my lathe.Thanks Richard, I presume that is from experience of the HY?
It would be nice if it actually mentioned exactly what it did in the manual!
Looked at a couple of phase converters it would make it easy to sort it out electronically, the last one I seen operating was very loud not sure if that was normal but it put me off it would've been louder than the lathe, the vfd I've bought could always be used for something else down the line, if there's a better way please let me knowProbably too late as Cheesie has ordered a VFD but I would have seriously looked for a phase converter and left all of the controls intact and do the speed control on the gears as Mr Harrison intended. I've to secondhand units, one came with a lathe and the other bought cheaply for not much more than a VFD (there does seem to be a regular supply of these appearing on the auction sites but perhaps N.I. might be a bit more difficult to source). I would suggest even with a VFD that for long running operations at slow speed that the motor is run at 50 Hz and speed reduced on the gearing such that the motor will get its designed cooling airflow through it.
Yes, as with everything, they vary greatly in quality. Years ago I had a very crude one which made the motor run very noisily and was in no doubt due to having a very square wave output. The two I have now are by Power Capacitors who seem to be the top dogs at making them. The rotary one is quiet and the output seems very good as the motors also run quietly. I bought this with the lathe, milling machine and two drills which it was powering via a 3-phase 'circuit' in the owner's workshop as it made good sense to only have one piece of kit and to not have to change any of the machine wiring. I don't think from memory that I paid him more than it would have cost me for four VFDs. I also bought a static set just to power one machine in a separate workshop and this has proved quiet in operation.Looked at a couple of phase converters it would make it easy to sort it out electronically, the last one I seen operating was very loud not sure if that was normal but it put me off it would've been louder than the lathe, the vfd I've bought could always be used for something else down the line, if there's a better way please let me know
One last word on the emergency stop, you should have one but it's not recommended to cut the mains power to a VFD and *may* blow it up. Also the lathe may stop *slower* (ie freewheel) if you cut power rather than hit the stop button. For that reason I personally have mine to both effectively hit the stop and disconnect all of the controls. This doesn't however disconnect mains although functionally is no different to the "factory" e-stop on other machines I have (for example my pillar drill). You may however decide that it's better to take the (probably small) risk of the VFD blowing up and just go for disconnect it.
Last one I was working beside was really loud I've watched some of your YouTube recordings and can't hear it running, is it inbthe same room, what hp rating is yours,Mine runs from a "Transwave" rotary converter .
Just a plug on the lathe and everything works as it should.
2 speed motor coolant pump and low voltage light as well as the reverse switch.
I alsu run other 3 phase machines from the same converter (not at the same time)
It really is plug and play .
2.5 Hp The unit is not at all noisey . Microphones and video are very hard to balance between my voice and the mechanical noise of the lathe .Last one I was working beside was really loud I've watched some of your YouTube recordings and can't hear it running, is it inbthe same room, what hp rating is yours,
Think my wife is looking forward to me being in the garage more2.5 Hp The unit is not at all noisey . Microphones and video are very hard to balance between my voice and the mechanical noise of the lathe .
The garage is joined to the house and the wife never complains .
Lets clarify that , She never complains about the noise of the lathe .
