The DECKEL-FP3 conversion project, which had been suspended for several years, was started
- Thread starter a smile
- Start date
All connections to the console are complete.
The IO board (x2/y2) inside the operation table is used to control the indicator light and switch added to the operation panel, and the control cabinet has a group of (X1/Y1)IO board, which is an expansion accessory for the numerical control system.
The control cabinet also needs major changes.
Servo control area circuit finishing.
Add a filter (installed at the output of the isolation transformer)
In recent years, the circuit transformation and learning have made me progress a lot, which has solved many problems in previous years!
The auxiliary function logic control circuit is much simplified, but still requires a lot of line arrangement.
This is the first time to install the numerical control system, need to consult a lot of information, also need to learn a lot of new knowledge, so the progress is very slow. I need to minimize errors, and I need to optimize the circuit and add some additional functions, so it will take up a lot of your space, and I hope to get your suggestions.
Moreover, the PLC control part in the last picture is a mechanical shift control system rewritten in accordance with the logic of the original machine, which was assembled by a friend of mine several years ago. If anyone in the forum has the same needs, I am willing to share with you ------

That's quite the filter. I've never seen one like that. Usually an isolation transformer doesn't need one.
Was the output too noisy without it?
The servo drive is AC220*3, and we are accessing AC380*3, so the isolation transformer is definitely needed, and there will be various clutter interference in the circuit, adding a filter should be beneficial. Also, I happened to buy some filters at a very cheap time, so the addition can only be beneficial.
I think we are having a small translation problem. I'd call that a step down transformer, not an isolation transformer.
I can see why a filter might be useful when used with a step-down transformer.
But still, it is a nice filter. Great find!
Indeed, we can choose a self-coupling transformer, or we can choose an isolation transformer, because everyone uses an isolation transformer on CNC equipment. I understand that it is safer and more pure, and I also think that the self-coupling transformer can be used, but it should also be better isolation. It is better to follow most people's conventions - unless I can find a better solution from theory and practice, or I have enough cases to prove that my solution is better.
Please understand the shackles of a student in his apprenticeship! I think I am already a person who likes to break the rules, but it takes time and experience, especially the circuit is a weak point for me, copying and using is the wise choice!
I'd love to see more of your studio in action!
All very good points. A little filtering won't hurt especially when you have them anyway.
Documenting what I do has never been one of my strong points. By the time I get around to thinking about documenting, I'm already done..... It's probably a character flaw of mine. So is neatness and tidyness.
The tube is not big, it just looks huge because of the Angle of the shot.
I think for amateur electricians, wire numbering is a tedious thing, although I have some experience, but it is still a big challenge. I try to make the line number clear and detailed, which is good for future maintenance, but it costs a lot of time.
When transforming this milling machine a few years ago, because there was no line number machine, I could only use markers and handwritten line numbers, which was more troublesome!
I basically do not have the same mechanical enthusiasts around, so all the tools you need to use can only be purchased by yourself, if there are a lot of common hobbies of friends, you can borrow tools from each other, you can save a lot of unnecessary tool reserves, because the frequency of line machine use is very low.
Slow but steady progress makes the remaining work less and less, and my experience now allows me to streamline about 30% of the circuit compared to the transformation plan of 3 years ago, so every effort will have an equivalent, well worth the return!
Bought a very cheap cable label machine, tried to print some today, and finally can give up manual labeling.
I try my best to use the electronic plug of the original machine tool. First, it can maintain the original degree as much as possible, second, it can reduce some workload, third, it can reduce the investment of capital, saving not a small amount (because this kind of plug parts are very expensive), fourth, the quality of these plug parts is very good, very reliable, far better than the new Chinese plug parts I buy.
The cable label printer purchased a few days ago subverted my cognition, I did not think that such a cheap printer is actually very good to use, I doubt that the manufacturer can make a profit in the limited price (69RMB~14 Canadian dollars), but the consumables are relatively expensive, I think it is very expensive - about 5 Canadian dollars/roll. In any case, this saves me the trouble of manually writing line numbers, and handwritten ones are not easily distinguishable and can be easily erased.
The labels given by the printer were consumed very quickly, 100 of them were used up in one afternoon. I need to purchase new labels as soon as possible.

Nothing can beat printer ink for that criminal behaviour. They sell a new printer with ink for half what the ink alone costs.
Today, the transformer cable was replaced, the original cable was 2.5mm*4, because the planned is a 3-axis motor, so the cable is a little small. I use used cables, but the quality is very good, I use mostly bought old cables, they are cheap and oxygen free copper.
Cable marking takes a lot of time, but it is a great help for future maintenance.
I hope you get lots of usefulness & enjoyment out of your FP3 once its all completed. One thing for sure, the next owner will get a very clean & logical electrical layout!
By the way, did you happen to see Stefan's recent YouTube episode? He shows some very interesting Deckel FP mill documents from early years. Not just machine components but many machining examples & configurations. Some documents might be available digitally but I wasn't quite clear about that. He didn't leave a link so I think he was 'gifted' the hardcopies? It would make for interesting reading.

Thank you very much for your sharing, I think this is a useful teaching material that will help many new friends who are just getting to know DECKEL milling machine. I also learned a lot about the functions of accessories, which can be a good understanding of the architecture of German industrial machine tools.
Dig out the LED light strip bought a few years ago: 12V~0.37A, install the cabinet light first.
2 strings of 6 parallel. Total power approx. 54W, single side power 27W... It's so bright,
you don't have to use work lights. Install an extra travel switch and use the cabinet door to control the light switch.
I changed the opening and closing function of the cabinet door, which was supposed to be for security control, and I used it to control the cabinet lighting.
Finally know why the cabinet interior is why the choice of orange, which will make the light better reflection, make the interior appear brighter, conducive to the maintenance of the cabinet.
The strong current (380V high voltage appliance) of the control cabinet is installed, and the basic layout of the wire is completed.
The last one is a test shot that was resized after being shot with a SONY A7. I need to know what equipment is best for the forum.
