We have a 1987 Sharnoa SDC-80D and I am working on the shop floorplan, If anybody has a copy of the floorplan for this machine it would be great if you could email me a image file of it.

Thanks,

We have a old, old Windows 2000 computer with a CRT monitor that I want to get rid of and set up my wire guy with my old Dell Precision T3500 that is running Windows 7, it originally had Windows...

We have a 1995 760-22 VMC that sits off most of the time. A few weeks ago one of the guys fired it up for a small job, and X would not home.

got following error and drive errors. thought the...

Fizzissist,

thanks for your reply,

My continued research has found that this is a single phase PSC type motor on this cooling blower.

And now the capacitor is suspect, if it is bad, it...

We had a Spindle cooling fan overtemp alarm back last spring, Maintenance replaced it and all was well until this week when it did it again, The operator opened up the end of the machine and put a...

Mike,

So far to good... Talked to the operator earlier this morning and Z is holding its position...

(Knock on wood) I told him to try to see if he can correlate the problem to the...

Well Guys,

I got the new shielded Twisted Pair Cable installed last Friday Afternoon.

Now the encoder signals feed directly into the Motion Card for the Z axis.

Got the shield connected at...

That would most likely mean that it is single ended:

a, b, z, V+, V0 and probably a voltage sense line.

the voltage sense feeds your V+ back to the power supply so it can adjust its output...

japco43,

How many signal wires come out of the Encoder ??

single ended has a,b,z V+ and Common (0V)

Differential has a, a-not, b, b-not, z, z-not, V+ and Common (0V)

If the encoder is...

I see this is a very old post, hope you got it fixed...

Is the machine closed loop (encoder or Glass Scale)

Servo or stepper ??

If it is Stepper it is probably open loop, it is most likely...

Al,

Ref ROD 426... I was referencing the diagram only I already knew the encoder has only a,b,z and complments. :-)



There are only 2 wires per axis going to the servo drives, SO I...

Thanks Mike,

I was thinking that they may be voltage sense lines.....

do not forget that this diagram is for a servo motor with the encoder integral to it.

My set up is a Brush type DC...

The Motion Card IS made by CNC-Systems in France for Sharnoa..

and I got a pin out for the SE 362 B1 motion card see attached.


looks to me that I should be able to hook the ROD 426 Encoder...

Al,

I am thinking that the Sharnoa Machines were built by a sister company of CNC Systems, and perhaps CNC Systems built the motion control board, and all the electronics/software for the...

Mike,

what is in the box is a breadboard with 3 separate circuits, one for each axis.

there is a MC3487P Line Driver IC chip. a couple of resisters, an electrolytic cap and a small...

the converter box is just before the motion card

cables from encoders enter from top

it is labeled SE 380

the motion card is labeled SE 362 B1

I am thinking these are Sharnoa Part...

Al & Mike,

Thanks for your continued input...

Mike,

I agree with you, there is no need to have the converter box, unless my motion card requires a voltage other than 5 VDC. I have not...

back side pic

nope won't upload... So you can only see the front.

I have not been able to find much of anything on my motion control card.

I can tell you that it is an ISA 16 bit bus it...

There is no name on the motion card here are pics of front and back.

seem to only be able to upload one of the pics I will try the other in another posting.

Al,

I can try that at a later time... right now the shop is using the machine on a job...

I do not know if you have any experience with this Sharnoa Tiger 6 control, but I am not impressed...

yes see first pic, to left of display there are jog arrows


second pic is of computer and motion card (Right most card in chassis)

third pic is of the Fanuc A06B-6047-H003 Velocity Control...

AL,

there is no hand wheel see pics

I do not know if anybody knows how to display following error either.

When I say drift I mean the following:

If the axis is not commanded to move it stays in position indefinitely.

As the axis is moved + and - over time it loses position more and more, as it is...

Mike,

the encoder is a Heidenhain ROD 426

it looks newer than the other two on X & Y

Al,

The display on the control (again Tiger 6 Sharnoa) indicates the "programed" position.

ROBBY 68

The servo is a Brush type DC and it is driven by a DC Velocity control

Fanuc:

A06B-6047-H003 Velocity Control Unit

20M Servo # A06B-0652-B005

ROBBY 68

It used to but has been removed.... before we bought it... rotary encoders ONLY now...


:(

Mike,

again this is a 1987 machine.... that we bought used some years ago, It has had many issues that were dealt with as they have appeared, this is the latest.

The encoder/coupling/ballscrew...

Al,

Yes this is a composite system Sharnoa as you may already know was way ahead of the rest of CNC technology with their controls... They were PC based and had all kinds of powerful...

Ok I started looking at the encoder input "chain" and here is what I have found:

The Z axis encoder is Heidenhan ROD type. It is connected to a terminal strip at the encoder and then a 4 pair...

could not find a section for Sharnoa machines so I posted here were my other post in regards to this issue is....


Looking for a parts diagram of section drawing showing how the encoder is...
