Cyclone Fanuc OT-B lathe error 1008,1017 & 1032

[Lone_Ranger]

wires 61 and 68 are dead in transformer box, and at every junction on the strip in the back cabinet. Wires 24 and 25 also seem dead in the box.

No sign of the dial overload thing you talked about

Hi Bob

OK, wires 24 and 25 carry the AC supply to the 24V DC PSU, you should have roughly 32~34V AC across those wires at the small transformer that is slightly above and to the right of the 24V DC PSU. The 25 should have a extra tag on the wire so it shows 25L (Live), the 24 wire should have a link from it to Earth on the same terminal block on top of the transformer, there should actually be 2 wires marked 24 in the same terminal and only 1 marked 25L.

On the other side of the tranformer there is another terminal block that brings in the supply for the transformer, you should get 415V across the 2 wires going to that terminal block.

Right, now the 25L wire goes to a Fuse right over the other side of the box to a Black fuse holder that is on the side of a 2 bank Circuit Breaker that is close to the main isolator switch, you should check that fuse if you haven`t already done so!!

I don`t have the drawings here but would guess that 24 & 25 are meant to be 110volts AC.

This will power any cabinet cooling fans, lights, solenoids, contactors & the 24Volt PSU that sounds like it comes out on wires 61 & 68

[Emimec]

Can you post a photo of the inside of the transformer box & the electrical connections in the main control box.

It may be that the 24volts dc is 60(0v) & 61(+24v).

The power supply we used back then was a silver chasis with a transformer & pcb mounted on it if that helps to identify it.

Yes, will post photo. thank you.
I have what you describe, but wires 24black & 25black then 61Blue & 68 blue.
I will check for 24vdc on 68
Thank you
Bob

Picture IMG_2831 (WinCE).JPG is of the 24volt psu.

The two blacks are the input which should be 110 volts ac.

The two blues are the output which should be 24 volts dc.

[Emimec]

No sign of an red on lcd light on the 24vdc power board.

Is the reset button mentioned actually on the motor, or the board in the cabinet, behind the motor?

[Emimec]

Forgot to say, fuse on the 2 bank breaker, mounted by the isolator switch in the box is ok. If removed, the fan and light do not run in the machine cabinet.

[Martin]

I can`t remember any red LED on the 24 volt power supply or a reset button on a Fanuc drive. There may be a curcuit breaker on the drive unit (photo IMG_2839 (WinCE).JPG ) If there is a breaker it will be under the large plug on the bottom left.
I still think that it sounds more like the 24volts/E-stop line though.

The 110 volts has to be OK if the fan & light are on.

Hi Martin

From Bobs photos I see that the 24V PSU I have in my box doesn`t appear to be the same one Bob has, so probably no LED on his. My unit is flat on the panel mounting plate and Bobs is "end on".

However not a problem as we have I think verified that there is voltage coming out of the transformer that feeds the 24V PSU among other things and the other things appear to be working.

Hi Bob

You say you don`t have any Voltage input to the 24V PSU yes??
But you have output from the transformer yes??
So that must mean that somewhere between the transformer and the 24V PSU there is a problem??
Think I got that right!!

I`ll double check the Voltages I have at the transformer and PSU etc for you tomorrow as I am at work again!!

Many thanks to you and Martin.

I wonder, is it possible to get a wiring diagram that is for this transformer box? The one I have is not the correct one. I would be more able to trace things then.
Bob

[Martin]

I will see if I can dig some out Monday morning.
Do you know who the original customer was?

[Emimec]

The only history of the machine known is that it was rumoured to have been donated to the college from a company or designer that made or designed Hozelock fittings. It has been at college for around 9 years, unused.
Thanks again
Bob

[Emimec]

Update:
Power in on 24 and 25 to the small 24v transformer. 110v ac

No power on 61 or 68 coming out of the pcb on the 24v board beside the small transformer

I think I was using DC on the meter for the original checks oops !

Bob

You have 110V on the Black wires 24 and 25 actually at the 24V PSU?

If so and there is no 24V output then sounds like the PSU is faulty and needs to be either repaired/replaced.

Rob

[Emimec]

Yee Haaa !!!

I removed the pcb from its mountings on the 24v transformer, the top left one in the box. Rechecked for power on the blue 61 and 68 wires, and bingo, got it. Switched machine on, and hey presto it works now. There must be a dodgy connection to the board or on the board. Left hanging, all is functional.

Machine ran ok, but threw up an alarm for turret positioning error. It seems when you manually index to turret position 1 it goes to 2. Switch is not reading the same as the turret.

Spindle responded to M codes correctly for forward and reverse.

I am so grateful for all the help given to me via this forum.

Hi Bob

Magic, glad it`s going OK now!!


Try running a couple of tool changes in MDI mode so you can see what the control is doing, if it goes to the correct turret position using the control then I`m not sure why the turret would be off position other than the fact it is "phase dependent" and it can sometimes just need two of your main input phases swapping over!!
So first of all try setting your manual switch to position 1 and then do a tool change using the MDI to make the turret go to Tool 1 and with a bit of luck they will match up again!!
To use MDI press the MDI button and then the Programs button, then on that screen you can input the following
G97 then press Input (You may not need this but do it anyway!!)
T01 then press Input
M06 then press Input
Then press Cycle Start and the machine should do a tool change hopefully to the right position.

If that doesn`t work try this,
To get the turret to correct positioning if it doesn`t match the switch position, switch everything off an remove the small plate/cover on the bottom of the turret, inside you will find a "castellated nut", using something like a pair of narrow nose pliers turn the shaft till you have the No 1 turret position in the correct place i.e. turret Nos 1 & 4 are parallel with the X axis slide. Tool 4 pointing upwards and tool 1 pointing downwards as you view it. Then make sure the switch is in the No 1 position and then switch back on, you should then get the switch and the positions back as they should be!

Now you will really enjoy some great machining, the Cyclone is fast and great to use!!
Your only downside will be the small memory, probably about 4Kb which will only usually do one reasonable size program, you will need to learn all the "canned cycles" for the machine as using them will save many lines of G code!!
Not that it is a big problem as most programs only take seconds to load via the RS232 anyway!!!

I don`t bother on mine as I got hold of 4 memory chips from the US that upgraded my memory to 128K!!

So, best of luck and I`m glad I was maybe able to help you!!

Enjoy!!

Rob

Hi Rob

I'll run through all your suggestions tomorrow, and let you know what happens.

The machine sounds as sweet as could be. Biggest downside is that it does not have an auto opening chuck or collet system fitted. I so wanted to replace the Emimec with the Cyclone. I was going to use the air fed bar feed from the emimec. The Cyclone will not be very productive as it stands, at least the emimec runs all day (if your lucky)without too much attention. I cant imagine opening the chuck by hand every 3 minutes to advance a bar !!!

I still need to establish where the bad joint is on the pcb, but will sort that later.

Many thanks
Bob

[Martin]

Glad it`s up & running.


Regarding the toolchanger.

Are the diagnostic set right?
Diagnostic 453 bit 4 = Tool select switch starts at binary 0

Other than that change over 2 of the phases to the machine if the toolpost is moving the wrong direction.

Hi Martin
I did try this, and changed my bit to what I think it should look like, but it didnt do anything. If I am right, my bit 4 was at a 1. I changed it to a 0. I am not to confident how this diagnostics works.

I also tried Rob's suggestions, MDI indexing, but it seems to go into error state. Followed how to rotate manually using the screw but still no joy, my turret actually keeps revolving without stopping, or sometimes stopping in different places?
Bob

[Emimec]

Hi Rob
Followed yours and Martins advice, but still have an error warning 1003 for turret positionial error. I did the manual moving of the turret, to get to position 1.

My turret either rotates one station, and then seems to knock out a contactor in the back of the machine, or rotates continually until you stop it using the top left red button on the keypad. (I think)

It almost feels that something cant decide where the turret is, and when to stop it.
Bob

[Martin]

What toolpost is fitted to your machine?

Are you sure it is not just the phases to the machine? Have you tried changing 2 phases over?

Don`t forget you need to set the 450 diagnostics for the toolpost.

451.0 Baruffaldi RH80 fitted
451.1 0=6st, 1=8st
453.4 Tool select switch starts at binary 0

As Bradders posted earlier the dignostics read from right to left & start at 0.

Bit No
7 6 5 4 3 2 1 0

To make them active set it to a 1

Therfore if it is a 8 station toolpost set bit 1 to a 1
Therfore diagnostic 451 would read 00000010
