Description

Lenze EVF8201-E Frequency Inverter

Product Dimensions：

The Lenze EVF8201-E is a high-performance, compact AC frequency inverter from the legacy 8200 vector series. It is engineered to provide precise speed and torque control for standard three-phase asynchronous motors in a wide range of industrial applications.

Product Detailed Description

The EVF8201-E belongs to Lenze’s modular 8200 vector family. The “EVF” prefix designates it as a frequency inverter, and its modular structure allows it to be customized with various plug-in communication modules (such as CANopen, PROFIBUS, or Interbus) and function modules to seamlessly integrate into complex automation architectures. It utilizes advanced vector control algorithms to deliver high dynamic performance even at low speeds.

Technical Parameters

Product Advantages

• Sensorless Vector Control: Excellent torque characteristics at low speeds and precise speed regulation without needing expensive encoder feedback.
• Modular Adaptability: Interface options are pluggable. If your network architecture changes from standard I/O to a fieldbus system like CANopen, you only need to swap the module, not the entire drive.
• Compact “Side-by-Side” Mounting: Optimized cooling design allows multiple units to be mounted adjacent to each other in the panel, maximizing cabinet space.
• Global Compliance: Built to meet international standards including CE, UL, and cUL, making it suitable for worldwide machinery exports.
• User-Friendly Software: Can be easily parameterized and diagnosed using Lenze’s Global Drive Control (GDC) software tool.

Important Considerations & Precautions

• Input Power Verification: This specific model is designed for a 1-Phase 230V input grid. Connecting it to a 3-phase supply or a higher voltage network (like 400/480V) will permanently damage the internal input bridge.
• Residual Capacitance Charge: Danger of electrical shock! After disconnecting the power supply, wait at least 5 minutes before touching any terminals to allow the internal DC bus capacitors to fully discharge.
• Thermal Management: When mounting units side-by-side, ensure adequate airflow and clear paths for the integrated cooling fins. Operating the drive above 40°C without derating can significantly shorten its lifespan.
• Motor Insulation: If utilizing long motor cables (exceeding 10 to 15 meters), it is highly recommended to install a motor reactor or dv/dt filter to shield the motor insulation from voltage spikes.

Product Applications

The EVF8201-E is highly versatile and frequently utilized in light-to-medium industrial machinery:

• Conveyor Systems: Speed-controlled handling lines, packaging lanes, and roller systems.
• Pumps and Fans: HVAC ventilation control and centrifugal pumps requiring energy-efficient variable speed operation.
• Textile Machinery: Controlling winding mechanisms, feed rollers, and auxiliary spinning equipment.
• Printing and Paper Processing: Driving material feed systems and small cross-cutters.
• General Machine Tools: Powering auxiliary axes, small mixers, and dosing pumps.
