2. Key Technical Specifications

The following table summarizes the critical parameters of the VLT FC 302 series, with a focus on the specified model:

3. Product Features and Benefits

3.1 Advanced Motor Control

The VLT FC 302 employs sensorless vector control (SVC) technology, enabling precise speed and torque regulation without requiring a feedback encoder. This ensures smooth motor operation even at low speeds, making it ideal for applications like conveyors, pumps, and fans.

3.2 Energy Efficiency

With built-in energy-saving algorithms, the drive optimizes motor power consumption by adjusting voltage and frequency in real time. The 0.75 kW rating of the FC-302PK75T5E20H1XNCXXXSXXXXANBXCXXXXDX model makes it suitable for small to medium-duty applications where energy efficiency is critical.

3.3 Compact and Robust Design

The IP20 enclosure protects against solid objects larger than 12.5 mm, ensuring reliability in industrial environments. Despite its compact footprint, the drive supports a wide range of optional modules, including I/O expansions and communication interfaces.

3.4 User-Friendly Interface

A digital local control panel (LCP) with a backlit display provides intuitive navigation for parameter adjustments, diagnostics, and status monitoring. The LCP supports multiple languages and includes a keypad for direct input.

3.5 Connectivity and Integration

The integrated EtherNet/IP MCA 121 module enables seamless integration with industrial networks, facilitating remote monitoring and control via SCADA systems or PLCs. Additional protocols like PROFIBUS and Modbus RTU are available as optional upgrades.

3.6 Environmental Resistance

The PCB coating enhances resistance to humidity, dust, and corrosive environments, extending the drive’s lifespan in harsh conditions.

4. Application Areas

The VLT FC 302 series is versatile across industries:

• HVAC Systems: Precision control of fans and pumps in heating, ventilation, and air conditioning.
• Water/Wastewater Treatment: Regulating pump speeds to optimize flow rates and reduce energy use.
• Material Handling: Smooth acceleration/deceleration in conveyor systems and elevators.
• Food and Beverage: Compliance with hygiene standards in packaging and processing lines.
• Textile Machinery: Consistent tension control in spinning and weaving operations.

5. Installation and Maintenance

5.1 Installation
