Profisafe (STO function) between s7-315F and simotion D435-2 - 7 drives

Hey,
my problem is :
is there a possibility to establish profisafe connection between S7-315f-PN and Simotion D435-2-PN while using 7 drives/axes. All I need is STO function.

According to siemens documentation:
only 6 axes overall, while maximum 4 drives in 1 drive-cliq line to assure STO in deafult time. What if I will change the time, the max. number of drives will rise? Is there possibility to bypass this problem? Please help.




1) Our encoders have SIN/COS outputs. Heidenhain - multiturn endat 2.1 eqn1125

After 6 axis, a simotion D system needs a cx-32 or another cu320.
These control the sinamics part and contain the safety integrated

this is a quick explanation. Also sto does not need a license

I know about the license.

Are you sure about the CX32? Have you read it in any siemens documentation or is it your personal experience? I did not find any reliable source.

Yes. I'm sure
Study what Sinamics is and what Simotion does.

Just because a D435 can do say 32 or 64 axis. This
Doesn't mean you can drivecliq (daisy chain) all of these together

Also, his forum avatar is Sinamics. Nothing more could be more trustworthy than that

@JRW

Ok, you were right, i found the answer in siemens documentation.
Thank you.

My second question is:

Overview:

We need multi-turn absolute encoders (the choice for now -> Heidenhain - multiturn endat 2.1 eqn1125)

Question:

Is it permissible/possible to active the safety integrated functions while connecting simotion and encoders through endat 2.1 interface or do we have to choose other device?

I just can not argue with that!

.. What Siemens motor are you using?
Part number..
