RF30 Basement Install

The key.....

I nailed it the first go. The thought of re-installing the pulley on the mill umpteen times was great motivation to do her right the first time LOL.

The motor spinning the pulley at 80HZ. I'm not discerning any significant vibration or visible run out.
 
Spent the day mounting the VFD and ESD switch on my mill bench today.

Out of the way but accessible. Took two trips to Rona and one to Lowes to find a suitable flush mount box to house the ESD switch. Man this 3 PH motor is quiet and smooth. When I was finished wiring everything up I gave the motor a test run and thought hmmmm some thing is wrong here it's not running, but it was.

Tomorrow I need to dig out all the crap that's under the bench so that I can route the power cords. Not Fun.
 
Looks good Craig. Wish I would have noticed that VFD when it was that super sale. Keep us updated on how it works.

Do you need to be able to run in reverse? This one doesn't support that as far as I can tell so far.
This one may go up for sale if my AliExpress VFD ever makes it out of mainland China. Ordered Oct 15 and still stuck in China.

I was just going to buy so I had one at that price. I don't even have a mill currently.

did your translated manual not say there was jog FWD and jog REV? If that is the case, then I don’t see why it would not give you FWD and REV.

from the lates post in the your “translation” thread items 9, 10, 11, and 12 seem to be the lugs where you select direction of rotation. First, you probably have to set the internal parameters to look at those inputs. Then, depending on the polarity of these inputs, the motor will run FWD or in REV.

My TECOs are exactly like that: enable the external inputs and then I set the direction with the original FWD/REV switch on the mill.

I've tried setting the F0.21-F0.25 parameters to no avail. There is no reverse jog option that I can find. You can set the jog frequency, jog acceleration and jog deceleration times and that's it. The jog is weird (or so I think). When you hold down the MF-K key it runs up to the jog freq and when you release the key it stops.
 
Is there a little terminal strip where one can connect external control wires? It would be screw terminal that would accept maybe AWG 24 or smaller wires only.

From your translation, the ”Keyed/Keying” parameters could refer to the bottons on the key pad. The “wire“ reference could mean the external wires connected to the secondary terminal strip. Once enabled, the direction is controlled by the +12V DC (or whatever yours needs) inputs to those connections.

That will be your controls. Once you close common with one of the x connections it should do what you have programmed. So like x1 to common is fwd and x2 to common is reverse. Etc.

ok..... nothing is labeled COM and there is no X6. So what is COM? Is it GND?

Phew.... long day.... finally got the 3PH motor mounted and running.

SELF.JPG


Started out by pulling all this junk out from under the bench. The plus side of that exercise is that I purged some stuff that hasn't seen the light of day in 15 years.

Next up was routing the cords and anchoring them. NOT FUN laying on your back on the raised shelf trying to set screws into something that's 4" from you nose.

Then came dismounting this 45 lb beast. Had to pull all of the top end. Idler assembly, motor pulley, spindle pulley, and belt cover etc.

Finally mounted the 35 lb 3 PH motor. First go I discovered that the belt cover interfered with the motor, so I had to dismount the motor and lower it on the mounting plate a 1/4". But finally she's up and running.

I'm impressed with how quite and smooth this thing runs.

I'm belted for 770 RPM and 60 HZ on the VFD gives me 790 RPM.

80 HZ is yielding 1055 RPM and 30 HZ is turning around 400 RPM.

So one belt up and two down without changing anything but the VFD HZ. As to the torque being usable in those ranges is still to be seen.

I'm going to feel this all tomorrow I'm sure.

So I wired X1 to GND (COM?) and programmed it to be keyed reverse operation. No effect?

What your eluding to here doesn't make sense to me. There are 5 X terminals. If all 5 are programed differently and all 5 are wired to COM which one takes precedence?
 
You would need to wire in a switch to each of the 5 inputs so they could be connected to common one at a time to perform different functions.
This is an example from my Huanyang vfd manual. In this example you can see that if the common terminal is connected to the top terminal it would give a forward rotation request to the vfd. The function of each of the input terminals is programmable. Your really need an English manual. Maybe it is similar to my Huanyang. I have the manual stored on Google Drive. PM me your email address and I send you a link to it.

There two modes of operation:
1) everything is controlled from the attached keypad;
2) some parameters are controlled from external inputs

the VFD needs to know which mode of operation it is in (default is most likely 1)). This is where the Function programming parameters are set. Here is my Teco FM50

You can see under F10 you have a choice to set it to 0: Keypad or 1:Terminal. Same with Frequency Control (F11) - 0: Keypad, 1: Terminal (0~10V), 2: Terminal (4-20mA). It also shows the factory default for each of the function setting. Your VFD will be set up the same. You just need to tell it from where it gets the inputs (keypad or external) by setting the functions to the correct value.

Your main problem is that you don’t have an English manual. So you will have to step through all the functions and see which ones make sense. You do have the listing of what is where, so that should help you.

here Is the FM50 connection diagram. I know, not yours, but similar.

NOTE: I may be wrong in my previous post where I said that COM = GND. It could be, but not necessarily.
Just re-read my TECO FM50 manual and they use the term COM to represent 12V DC that is COMMON to multiple other circuit inputs.
I would check with a multi meter first. It may not be GND in your VFD!
 
This is an interesting thread, i moved a LC 30A into the basement last year and plan in the future to go with a 3phase motor and VFD. Absolutely hate changing speeds on this thing.
