Hello colleagues, I'm Brazilian, an industrial mechanic and electronics technician and I'm trying to acquire a used FAMUP x700 CNC milling machine that has been sitting idle for some time, so I need to get it working so I can evaluate the price.

I'm going to tell you a little about the history and what's going on here. This machine was purchased already used by buyer 1 who saw the machine for sale in another city with a 4th axis accessory and when it arrived his company was without the accessory. The seller removed the 4th axle and drive shaft. After some time, having used the machine even without the 4th axis, he sold it to buyer 2.

Buyer 2 is the one who is selling me the machine. He never got to use it. When he arrived at your company there was a problem related to the CNC that I can't say and problems with parameters. So seller 2 called a CNC technician who took the 810m away for repair, which is where the more serious problems started. The technician disappeared, along with the 810 controller disappearing for over a year. Until, in search of a new command, in another company specializing in physical CNC repairs, the same 810 module was discovered that had been left for repair and the person also disappeared, you see, it was seller 2's command that was taken for further assistance by the first technician.

As I had already tried to upload the original backup of the famup x700 by seller 2 without success, a backup of a famup x1000 was obtained from a factory representative who said that the 2 machines were identical but with larger axles and both were sent to the company that I had the 810 to do the charging and got the response that the charging would be successful.

Conclusion, the machine does not perform any function, ALARM 8 appears, wrong axis/spindle assigned. The reset button does not turn off. Checks I've already done: Sinumeric source LEDs are not accessible, small LCD display on the 1st. driver deleted, some other PLC errors (I believe that active PLC errors would not crash the machine, I will post a photo of the screen).

Errors found:

PLC low fluid level alarm, but the machine does not have a level sensor

I think the problem may be in what I'm going to describe now, but I haven't found the solution. The spindle encoder cable is connected to port 3 on board 2 (if I'm not mistaken x121 connector) which should represent md4000=2200 (correct?!), however when you rotate the spindle manually you mark the position of the axis, changing the connector cable still on board 2 by x111 and 131, when rotating the spindle the value of another axis "y" and "z" changes on the screen.

In the nc parameters we have the values ​​N2000 =1100, N2001 =1200, N2002 =1300, N2003 =2100, which indicates that the axes must be read by the input board 1 (or A) on the left of the cabinet, but as I said Using the spindle encoder cable, we saw that XYZ are being read by board 2 (or B).

I can't turn the axes manually, there is no opening without disassembling the machine. So I changed all the connectors that connect the axes to board 2 which signals the change on the screen through the encoder and the spindle cable to board 1, x121, but I got no results, I don't see any spindle rotation, I turned the machine off and on again and alarm 8 continues.

I've already changed the parameters, moved the axes from card 1 to card 2 and nothing solved it, the alarm continues. I changed the NC 4000, which is a spindle attribute, and nothing resolved it. I don't know what could be wrong with the axles anymore.

Hello colleagues, I'm Brazilian, an industrial mechanic and electronics technician and I'm trying to acquire a used FAMUP x700 CNC milling machine that has been sitting idle for some time, so I need to get it working so I can evaluate the price.

.

These are files that should be original to the machine, I don't understand Siemens' naming logic, but from what I observed, the files do not have headers that start with "%", the file named PCL I believe is what you call PCP, I didn't identify what L888 would be or the other so-called subprogramsX

....

These are files that are from a machine from the same manufacturer said by the seller to be identical to the X700 only with larger axes, model x1000.

 this is the photo of the sinumeric modules, the first module on the left of the source does not have any LED on, the second module which has a small LCD display does not show anything on this one either, it seems to me that the 810M does not enable the signal to start the source due to the ALARM 8 error

You have a long story, let me make the answer simple--

suggest you :

#1--make sure the 810M controller you finally found, is the same version as original

(810M teve GA1, GA2 e GA3 --- você precisa ter certeza de qual é o original)

-- How could I identify this just through the machine? There is no longer any way to look for the manufacturer or even the technical representatives at the time. Only if you hear any electrical connection that is different between the modules when changing from GA1 or GA2 or GA3, or perhaps due to the type of panel? It has an expanded panel like the one shown in the 810M/820 shared manual. EMCO bought Famup in 2004 in Italy

#2--You need to have all parameter back up---List below:

1--NCMD  %TEA1

2--PLC MD  %TEA2

3--PKC program in ASIC code %PCP

-- Below I show the files I have, TEA1, TEA2, PCP, PCA, SEA, PARAMETER_R, L888 and others. As you listed above, tea1=ncmd, tea2=mdplc, pcp=plc ascii.  I know that PCA=code alarm description. What are "R" and SEA Parameters? L888 always appears called in the file called "program", would it be a routine for ATC? The tool change system of this machine uses the displacement of the Z axis above to activate mechanical cams that bring the tool closer to the spindle.

when theses ready I can help you 

Alarm=8

Message from nc = ord 1, wrong axis / spindle assign.

What is alarm text of alarm 8?

We were able to get 6SN1145-1ba01-0ba1 and 6sn1145-1ba1-0ba2 16/21kw in China, these are more modern simodrive611 power supply numbers, being 0ba2 2014 for a very nice price of US$1300, in my country it costs US$3000, the question is can I use them without any problems? A technician in my country says 1ba01 uses more modern components. Will they be more resistant or more fragile? Would it be worth buying a 35/47kw 6SN1145-1ca01 in China for the price in my country of US$3000?

Could someone comment on my questions and doubts with supposed attempts to correct the problems. Thanks

To the colleagues who followed this post, here are the updates. The ALARM8 "axis not synchronized" in 810M was due to the axis input board in 810m being defective. I got one for testing and then we bought a used one.

The simodrive 16/21kw power supply was burnt out, we used a borrowed one to make progress on the problems.

After the power supply was replaced, a Y axis drive showed ERROR 7, and it had to be sent to the service center for repair. After all these problems were solved, we have a semi-operational machine, where the axis movements are working. Now we can reference the axis home.

Thinking that everything would be wonderful after months of struggle, we bought a 36/47kw power supply because we had reports from the technical support that the first machines with 16/21 had serious problems with the power supply burning out, and in the following years we were already using 36/47. The power supply was purchased and installed, and an unknown problem arose. The power supply's filter inductor began to make loud noises and overheat, even without activating the axis movement, only in ready-to-operate mode. We then needed to buy an inductor compatible with a 36/47kW power supply, and we ended up importing the inductor and the power filter module from Denmark to Brazil, since the price was lower than in Brazil itself.

Everything was ready once again, and now we tried to activate the spindle and nothing happened. We detected that the spindle drive also showed a no current error, which made us buy another used drive without even trying to fix this one.

drive changed, we lost the configuration of the 611U controller, downloaded the SIMOCOM-U software, did new programming and managed to get the spindle to run controlled by the PC, but now we can't run it by the CNC, when doing the M3S1000 command in MDI the command executes the same but we don't have the analog output of the 810M entering the 611U board to control the spindle speed.

We have already done a test with a 9Vdc battery box on pins 56 and 14 and we have spindle rotation. We are thinking that there is some restriction in the PLC, some input not activated that is not allowing the 810m to send the +-10v to control the spindle rotation, like an open door sensor for example. Having more news we will update the post again.
