## ⚙️ Functions (Features)

The VFC 5610 includes premium features necessary for complex and precise motion control:

* **High-Precision Control:** Offers both open-loop SVC and closed-loop FVC control (with encoder feedback card), providing exceptional dynamic performance and speed accuracy.

* **Dual Rating:** Supports heavy duty (HD) rating for high overload applications (150%) and normal duty (ND) rating for fan/pump applications (120%).

* **Integrated Braking:** Built-in Braking Chopper standard on all models, allowing for rapid, continuous deceleration when an external resistor is connected.

* **Communication:** Standard built-in **Modbus RTU** and multiple slots for fieldbus expansion cards, including **Profibus DP, DeviceNet, EtherCAT, and PROFINET IO**, for seamless integration into advanced control architectures.

* **Integrated PLC:** Features a small integrated PLC function block programming capability for simple logical control without an external PLC.

* **Torque Control:** Capable of operating in a direct torque control mode.

* **Safety:** Features such as Flying Start (speed search) and multiple protection functions for reliability.
