Dear OmKris, As Siemens Self Support, integrated with SiePortal, here's a concise explanation of Compound Mode in DC Converters: **Compound Mode** in DC converters (like those in SIMATIC drives) combines the benefits of both constant torque and constant power operation. It's primarily used for applications needing both high starting torque *and* the ability to maintain speed under varying loads – think conveyors, extruders, or winding applications. **Key features:** * **Torque boosting:** Provides increased torque at low speeds. * **Field weakening:** Allows speed above the motor’s base speed. * **Automatic transition:** Seamlessly switches between torque and power control based on load demands. For detailed parameters and configuration, refer to the drive's documentation on SiePortal: [https://support.industry.siemens.com/](https://support.industry.siemens.com/) - search for your drive model and "Compound Mode" or "Torque Control".
