## ⚙️ Functions (Features)

The EFC 3610 is equipped with essential functions for reliable machine operation:

* **Speed Control:** Multi-speed steps (up to 15 programmable speeds) and JOG mode.

* **PID Control:** Built-in **PID control** function, allowing the drive to manage closed-loop processes (e.g., maintaining constant pressure or flow).

* **Energy Saving:** Features such as automatic voltage regulation (AVR) and motor auto-tuning for optimized power consumption.

* **Integrated Braking:** Built-in braking chopper standard on all 400 V models (4 kW and above), allowing for direct connection of an external braking resistor for faster deceleration.

* **Communication:** Standard integrated **Modbus RTU** protocol via RS-485 for easy integration into basic control systems.

* **Operation:** Fixed 4-digit LED display and control panel for straightforward parameter setting and monitoring.

* **Protection:** Comprehensive protection features including overcurrent, overvoltage, undervoltage, motor overheating protection (I²t), and short circuit protection.
