Split from 380500 Profibus-DP alarm.

Hi, I cannot help you so much, if you can find Profibus DP connecter for the drive you disabled , try the "on/off" switch setting to see you can overcome the problem. if not --read the suggestion as following.

#1--If your company want to run this m/c and want to fix it --search on Google to see there is some possible services for this kind of m/c , In USA or In Canada, balancing the cost, make decision by yourself

#2--Siemens -yaskawa 840Di is another un-successful production, Siemens already discontinued , and maybe not support for it.--if you think your m/c mechanical part is worth to use. just rebuild the m/c with SINUMERIK 828D.

The reason I saying like above--as I know in this forum "PISCEAN2010" and myself company have 840Di,

and from my company, I have Same as you have--Siemens yaskawa 840Di, --but my m/c is made in Japan, Name "STARTS", AN 2 SPINDLE turning m/c. we have a lot of problems every year, we have same alalrms as you have now "Profibus error.....". check my profile--even for me , I cannot find root cause for the trouble of this kind of m/c, every time I let my boos call former Japanese Guy to come help us, the cost is about 15 thousand usd to 20 thousand..  the problem is the drive not Siemens drive. and profibus communication also need OEM knowledge--

I don't think you can get useful help from Siemens Forum

I am in Canada, attached picture is our mc/ operation interface

what do meaning it?

 Hello,

25201 - Alarm is a NC alarm means drive has reported serious problem, which is in relation with 380500.

380500 - Fault code 129 - Encoder back up data error. Power supply to absolute encoder has failed result in data lost. Check the encoder & encoder supply & if it is OK needs to be reconfigure.

380500 - Fault code 123 - Converter heat sink overheated. Check the ambient temp, check the wiring of converter temp sensor & function of temp sensor.

From you fault description it looks like drive control card has created problem & needs to check absolute encoder supply, function & drive wiring.

Please refer attached sheets for more information.

HTH. 

you will need to acknowledge the errors on the Yaskawa drives.  Code 129 means encoders lost their positions, probably from unplugged or battery on convertor dead.

this is done in in drive parameter 2798 for each of the axes.  you will need to change this to a value of 2 - this acknowledges that the encoders will need re-referenced.

after doing this, the value will change back to zero on its own (you may need to go axis +/- to see it update.)  When you have done this for all axes, you will have to do nckreset.

then you will have to re-reference each of the axes of the machine.

This happens when the battery of the convertor is dead, or the drive bus ribbon cable is disconnected, or the encoders are unplugged.  These systems do not have genuine absolute encoders, they are only battery backed.

The builder documentation will have the procedure for those machines to be homed.  Generally, move to known position.  Change 34210 axis md for each axis to 1, reference each axis to the known position, it will change to 2 when referenced.  Look in your machine book, the builders were generally in Japan, so they try to make it work like a Japanese control Keep relays and such concepts.

 @Jason, we have a similar m/c in our shop, your post may useful for me in the future thanks for share information

the problem is solved, Converter heat sink overheated was fixed.

I'm sorry for the late reply.
