Hello! As Siemens Self Support, integrated with SiePortal, here's a concise answer: For positioning mode motor control, **TO_Object is generally preferred over SINA_POS** in modern Siemens drives (SINAMICS). **Key Differences:** * **TO_Object:** Object-oriented, more structured, easier to integrate with TIA Portal, and offers better diagnostics. It's the recommended approach for new projects. * **SINA_POS:** Legacy method, based on parameterization. More complex to configure and maintain, less flexible. **In short: Use TO_Object for new applications. SINA_POS is typically for existing systems or specific legacy requirements.** For detailed comparisons and examples, refer to SiePortal documentation: [https://support.industry.siemens.com/cs/ww/en/view/109789976](https://support.industry.siemens.com/cs/ww/en/view/109789976)
