If so how ? The link for the document "Handling encoders in 2-encoder systems' is not working: https://support.industry.siemens.com/cs/ww/en/view/109477897 . That link is mentioned multiple times in other documentation for instance in https://support.industry.siemens.com/cs/attachments/33512621/Safety_Encoders_11_2021.pdf https://support.industry.siemens.com/cs/document/109793497/simatic-et-200sp-f-tm-count-1x1vpp-sin-cos-hf

In matter of a TM count a F-TM count module is needed to provide failsafe functions. The document you are referring to is handling the 2-econder system on the SINAMICS drives, not the use of F-TM count modules. For the F-TM count you can find an application example here https://support.industry.siemens.com/cs/ww/en/view/109805559 Anyway in case the information in the link is still of relevance, please contact your local Siemens sales representative, he can provide the information stated on ID 109477897 and you can discuss your solution in detail.
