Product Details：

Product Dimensions：

The AF-300G11 is designed for demanding industrial environments that require high torque and high accuracy. It utilizes Dynamic Torque Vector Control, an advanced Fuji Electric technology that calculates the motor's power requirements in real-time to optimize torque output even at low speeds. This specific unit is built to handle heavy-duty loads, making it a reliable choice for applications where motor performance is critical to the production process.

Product Specifications

Series: FRENIC-G11S / AF-300G11
Input Voltage: 3-Phase $380\text{V}$ to $480\text{V}$ (typically rated for 400V class systems)
Output Frequency Range: $0.1$ to $400\text{Hz}$
Control Method: Sinusoidal PWM control with Dynamic Torque Vector Control
Overload Capacity: $150\%$ of rated current for 1 minute (Heavy Duty rating)
Braking Torque: Built-in braking transistor for most frames in this range, allowing for rapid deceleration
Enclosure Rating: Typically IP20 (Open Type) for panel mounting
Communication: Standard RS-485 interface for network integration

Product Advantages

Superior Torque Performance: The Dynamic Torque Vector Control ensures stable motor operation across a wide speed range, providing the necessary "muscle" for high-inertia starts.
All-in-One Functionality: It features built-in PID control, multi-speed settings, and an integrated keypad with a digital display, reducing the need for external peripheral controllers.
Energy Efficiency: By optimizing the voltage-to-frequency ratio based on the actual load, the drive significantly reduces energy consumption compared to across-the-line motor starters.
Long Service Life Components: Fuji utilizes high-grade capacitors and cooling fans designed for extended operational life, minimizing maintenance downtime.
User-Friendly Interface: The detachable keypad allows for easy parameter copying and remote monitoring.

Important Considerations and Precautions

Installation Environment: Ensure the drive is installed in a clean, dry area. Since this model is generally IP20 rated, it must be protected from metal dust, oil mist, and direct moisture.
Heat Dissipation: Leave sufficient clearance around the unit for airflow. The internal fans must not be obstructed, as overheating can trigger the thermal protection trip.
Wiring Safety: Always wait at least five minutes after turning off the power before touching the terminals. The internal capacitors hold a high-voltage charge that takes time to dissipate.
Motor Insulation: When using this inverter with a $400\text{V}$ class motor and long cable runs, be aware of "micro-surge" voltages which can damage motor insulation. An output filter may be required.
Grounding: To prevent electrical shock and reduce electromagnetic interference (EMI), ensure the drive is properly grounded to a dedicated earth point.

Product Applications

The AF-300G11 6KG1143060X9B1 is highly versatile and found in numerous heavy-industrial sectors:

Conveyor Systems: Providing smooth acceleration and deceleration to prevent product damage and mechanical wear.
Fans and Pumps: Utilizing the PID control for pressure or flow regulation, which results in massive energy savings.
Extruders and Mixers: Handling high-viscosity materials that require consistent torque at varying speeds.
Hoists and Cranes: Delivering the high starting torque required to lift heavy loads safely from a standstill.
Machine Tools: Precise speed control for spindles and feed drives in metalworking or woodworking machinery.
