SINAMICS S120 with S7-315, how configuring the parameters P2507 = 2 and P971=1 by profibus networking

Hello Adam24,

I am with this problem. I am using a sinamics S120 with S7-315 (Simatic Manager).

I dont know how configuring the parameters P2507 = 2 and P971=1  by profibus networking. How did you do this?

By Starter in expert list... works well.

Split from S110 + absolute encode home position loss.

Hello Fermeida,

for the Profibus communication and Telegramm111/110 handling there is a sample program: LINK

If you use this, you should write the parametere number in the DB71/72/73.DBW16, and the parameter data in the *DBD.20, and then set the 'WRITE' bit *.DBX14.1
After this you wait for the 'BUSY' and 'DONE' w/o 'ERROR'.
Then you change into 'READ' mode by set the 'READ' bit *.DBX14.0, and wait for 'BUSY', 'DONE' w/o 'ERROR'.
After this you should see the parameter value in *.DBD20

You have to do this cycle every time you write a parameter, and then you want to check it. Use this in the following steps:

These are the steps to make the current position the reference point ('0'):

1) Set p2507:Absolute encoder adjustment status =[2]
p2507 will has [3] after position value memorized done.

'You have to check p2507 == 3 in the program (it means the current pos. value is 0 and the adjustment is finished), then do the next step'

2) p971:Save drive object parameters =[1] then do the RAM to ROM.
Automaticaly change p971 =[0] after done.

'You have to check p971 == 0 in the program (it means the saving is done).'

After these 2 simple steps you will see the current position in 0, and it is saved in the ROM, so it won't disappear after a power loss / restart.

Adam,

Thanks for your help.

I wasn't using telegram 111 and FB283. But, I changed the software and now it is ok.

But, There is a problem... I don't get to change the parameters P2507 and P971 by VAT.

Do you Know why?

I Added attachament of call FB283, Vat_Read and Vat_Write.

In "Read" shows a error number E111. What is this?

And in "Write" shows a error number E121. What is this?

Hello,

unfortunetly these error numbers are not describe the exact problem. There is a documentation about the use of FB283, I think you had to dowload it with the program from the link I gave you before.
But if not, then try to look for it. There are a lot of description about errors and how to handle these.

The documentation sais this by the way:

E1XY: Request error task completed with errors (response ID = 0x81/82); additional tasks aborted.
For more detailed error numbers, see instance DB DBW322 (Response.Error_Nr).

X= task type; Y=Task step

All I can think of, is if you didn't use telegram111, and now you changed your program, have you changed the configuration in the servo controller as well?

Regards,

Adam

Adam,

First, thanks for all.

I read this document about FB283.

The servo is working well.

Only, when i try to change the parameter by DB72.DBW16 / DBD20 / DBX14.0 / DBX14.1 that it doesn't work.

Do you have other idea?

Regards,

Fernando

Hi Adam,

nice to meet you. did you write or read this param toS120?
