2M2280N & Uniport Wiring - Basic Wiring

[BK2_SHOOTER]

Hi Guys,

Im in need of a little assistance. Im going to be wiring up my new 2M2280N drivers and a Uniport V2 BOB and some SY85STH156 motors. I have read through the manuals for all of the individual parts and am fairly confident that I understand what im ment to be doing, however I just want to check with others that may have tried hooking up these parts themselves.
I have laid out in the photo how i think things should be?
2169
I plan to start off running my setup from Mach 3, but to start with Im not going to bother with Hooking up Error Imputs (unless Youd advise against it)

Anybody know what i should do with the 3 small resistors that came with the controller? I saw them in the manual when discussing Anode / Cathode setups, and they had them shown in the schematic, but im not too sure what any of that does or how it works in laymans terms?

Does it matter if i use the PLS + or PLS-, or STEP + or STEP -?

Also, there is a ground output on each axis output of the BOB, Do i need to use this or just leave it empty?

Sorry for all of the Basic questions. Ive only used stepperworld drivers before and Turbocnc, but since ive upgraded all my drivers i just want to be 100% certain that im not going to screw anything up when i flick the switch.

Any help people can give me will be greatfully recieved.

Cheers

Martin.

Connect PLS- to DIR- and back to the X ground on the BoB
As shown wired up you have no return path.

[Gary]

the resistors are not needed in your case.
your have a choice of either:

Active high
Connect the PLS+ to the Step X and the PLS- to GND
and the Dir+ to Dir X and Dir- to gnd.

Or Active low.


Connect 5V to the PLS+ and the PLS- to the STep X and so on.

If you are still having problems, phone me on monday.

Blimey, you really ought to read the manual, part two is in English, page 8 has a wiring diagram :eek:

You can't call that a wiring diagram, it's a wandering done by a Dyslectic spider :whistling:

This may help.

Bloody clever spider considering he actually got it right.

Seriously though Gary some of these manuals leave a lot to be desired especially by the beginner.
That one for instance, it shows to output transistor in the controller and how it's connected.
[1] the average punter has no way of knowing which way up are the 3 wires.
[2] the average controller doesn't even have these as they are embedded in a chip.

Martins diagram was spot on but he was missing a wire, look at Roy's manuals, clear, concise, and a wire going to each part.

That Kinko manual has no wiring for the motors 4 wire 6 wire 8 wire ?

I feel it's a conspiracy by the makers to have an annual contest who can write the most obtuse manual.


Last year it was Siemens,
A local rewind shop were given a panel containing a large 30 HP invertor by a well know company who's sparkies couldn't wire it up. All they wanted was a stop start button and a pot on the end of a 40 foot cable connecting to this box.
They had the manual but couldn't understand it, neither could the rewind company so they sent it to me knowing I fitted loads of inverters.

I couldn't either :naughty: nearly 500 pages [ no joke ] and no reference to 3 wire operation, so a call to Siemens technical in London and er let me see, I'll ring you back.

Well they didn't, so I rung them back.

ST "we seem to be having a problem, give us an hour "

Hour passed and no call so called back,
ST "we will sort it out"

Another hour and Siemens in Germany called, you need to set parameter 24847624537308 to 5 then set parameter 527765 to 6 and parameter 83787575236782378 to 9

OK that worked but why isn't it in the book.

Drawing the transistors is a mistake because the manual says, "the rising edge is effective".

Leaves you wondering if it's the rising edge on the line or the rising edge on the transistor base.

I read it as "the LED off to on transition is effective".

You do need to read the manual so you know what is going to happen when you switch it on for the first time. Everything has to be ship shaped and Bristol fashion for the tuning cycle.

Well that makes sense :joker:

Try not to worry, a few more years and you will learn to parlez-electronique. It just takes a bit of time :whistling:

The wiring diagram is typical and you will find this diagram in many stepper driver manuals, from other driver manufactures and shows how the I/O would be in a typical system.
you need to understand that the manual is not aimed at a hobbyist or someone using it on a CNC system run by Mach3.
DIYCNC manual are oriented towards this market, and you will see diagrams showing how the Uniport is connected to the DVR25 because that driver is also made by DIYCNC.
I know that the Kinco manual is not the best around, but when you compare it to other chinese drivers it is actually particularly good, you should have seen the leadshine manuals before we looked over them.

It is not just the Chinese who have problems writing English, the French and Italians are worse.

I agree a lot of manuals for some products that used to be simple, like inverters are getting particualy complicated, and that is because they are becoming complicated products with a lot of features.
90% of people will not use these features, but the 10% that do use them are most likely the volume users.

At the end of the day, if you are having problems connecting the driver up, contact me and i will help.

[Gary]

Any commercial driver manual will be written for its typical user and this would be a commissioning engineer with years of experience installing drivers.
it is not oriented towards hobbyists, it is orientated towards its biggest user OEM's and machine builders.
Also the state of an output on a controller would be changed by a transistor, regardless if it is separate of within an IC.
The image of the transistor is as it would be within a typical controller, be it a parallel port, PLC, CNC controller or motion controller.

Hi Guys,

Thanks for all the replys. I didnt mean to spark such a debate though. I think the manuals very good and work for the people theyre aimed at. Personally Im really up to speed with software and mechanical design, but electronics is something i rarely do much with. As im new to CNC control its just a lot to learn, even though its relatively strait forward once you get in to it.

Ive ammended my diagram (see below) Have i got it right this time?
I cant wait to get the system running, by all accounts these drivers are super dupa, and thanks a lot for all the assistance.

That looks better, assuming the BOB knows it's a low/high transition on it's outputs that counts.

I have 3 of these drivers and they haven't put a foot wrong yet. Amazing power and speed. Haven't tried less than quarter stepping them so can't attest to the promised smoothness yet.

There is the worry that a mains spike or slump might not crock all 3 axes together, leaving it soldiering on with one or two halted. It has not been a problem for me, but I do have plans to put a watch on the ERR outputs before I run it unattended.

The motors run hot so you need a good thermal path to the mill body. Don't dump it all on the screw, a belt drive is a good thermal barrier :beer:

[Gary]

Looks good, as said above, the motors will run hot due to the high voltage, but as long as you let the heat get away from the motor that will be fine, mounting to be big chunk of metal is a good idea.
