S1200+S210: power blackout at the factory - motor lose its reference position

Hello Expert!

I have urgent problem.

As I asked before I'm using S1200_comb_S210. Motor article is 1FK2103-2AG10-1MA0.

Yesterday there was power blackout at the factory. And then motor lose its reference position. But this is absolute motor.It should never lose although power blackout.

S1200 comb S210 can be problem? should only configure with S1500 when use S210?

I want to attach my TIA project but it's too large to upload.

Can you tell me what is the problem? Please let me know the reason.

Best regards.

Hi,

GN_XIST1 is the encoder resolution = Encoder Steps/increments (2048) * fine resolution 2^11 (11 bit).

GN_XIST2 is the absolute value for the position, which will only be requested by the drive / technologyobject.

Actually the SINAMICS S210 is designed for a SIMATIC S7-1500, where the data of the encoder will be read automatically from the TO => "automatic data exchange for encoder values". This allows that the user do not have to be aware about the motor encoder values.

Ratio as in S7-1500 TO can not be set in S7-1200 TO

In the technology object configuration under“mechanic”you can set your load movement per motor revolution. Range is 0.0 up to 1.0e12.

Split from S1200+S210: encoder configuration .

Hello. Expert!

Definitely I did it.

But I found difference between TO_PosAx version and CPU version at the Overview of version what you attached manual.

My CPU version is V4.2 but TO's one is V5.0.

I have to use V6.0?

It has different Encoder connection and there is selection box about Automatic transfer of encoder parameters in the device. It can be reason?

I attached about version what I use CPU, S210, TO_PosAx.

Give me advice. Thanks a lot.

Hi,

When you using an absolute encoder and perform an “absolute encoder adjustment”, the actual position will be saved within the technology object.

The “absolute encoder adjustment” should be performed with the “MC_Home” function in “Mode = 7”. Have you done that?

Details can be found in the motion control manual S7-1200 (Chapter MC_Home):

Hello. Expert!

So, can you guess why the abs motor lose reference position?

Is it never happen?

Customer want solution about this trouble.

I attached screenshot about what you want. That is just difference between v6.0 and v5.0 TO.

Thanks in advance.

Hello. Expert

Attachment is what I did configure at TO.

Plz check whether something is wrong or not.

Best Regards.

Hi,

The TO can only work proper, when the encoder settings and also the reference/maximum speed of drive are set correct.

Could you also check the data exchange with the drive? What is selected in that field?

Hi,

have you checked P1082 and P2000 in the drive? Could you tell me the values please.
