E82EV552_4C Lenze 8200-series 5.5 kW Vector Frequency Inverter

Product Overview

The E82EV552_4C (E82EV552_4C) is a high-performance vector frequency inverter from the Lenze 8200-series, engineered to provide precise speed and torque regulation for three-phase asynchronous motors. Delivering a rated power of 5.5 kW, this drive is a cornerstone for industrial B2B applications such as automated conveyor systems, high-capacity mixing units, and sophisticated textile machinery. The E82EV552_4C is designed for 3-phase mains connections of 400 to 500 V, offering the versatility required for various international industrial power grids. By utilizing sensorless vector control, the drive ensures high dynamic response and torque stability even at low speeds, which is essential for maintaining process consistency in complex production environments. Although the 8200-series has entered its phase-out stage, this German-engineered drive remains a highly reliable solution for both system optimization and the maintenance of critical legacy infrastructure.

Technical Configuration

The E82EV552_4C (also identified by item code E82EV552K4C) features a modular hardware architecture that allows for flexible integration via plug-in AIF (Automation Interface) communication and I/O modules. The unit is housed in a compact chassis measuring 24.00 x 14.00 x 12.50 cm and weighs 3.60 kg, making it an ideal choice for high-density control cabinet installations. The drive includes integrated protection for overvoltage, short circuits, and motor thermal overload, ensuring long-term operational reliability. Its power stage is optimized for high efficiency and features an adjustable switching frequency to minimize motor noise. The modular design enables the drive to be easily adapted to various fieldbus systems—including CANopen, PROFIBUS, and RS232/485—ensuring seamless communication with central PLC or DCS architectures.

Technical Specifications

Technical FAQs

Can the E82EV552_4C be used in applications requiring high breakaway torque?

Yes. The 8200-series vector control algorithm is specifically designed to provide high torque at low speeds. For optimal performance, it is recommended to perform an "Auto-tuning" run during commissioning to accurately map the motor's electrical characteristics.

How do I handle the transition from this phased-out model to newer technology?

While the E82EV552_4C is in phase-out, original new and refurbished units are available to avoid immediate cabinet redesigns. For future-proofing, these units are typically replaced by the Lenze i550 series, though this requires a check for physical mounting and communication protocol compatibility.

Does this drive require an external 24 VDC supply for the control logic?

The drive can generate its own internal control voltage. However, an external 24 VDC auxiliary supply is highly recommended for networked systems to ensure that the communication module and diagnostics remain active even if the main 400/500 V power is disconnected.

Is it possible to transfer parameter sets between multiple drives?

Yes. By using the plug-in keypad or the Lenze Global Drive Control (GDC) software, you can store a complete parameter set from one E82EV552_4C and upload it to another, significantly reducing commissioning time for identical production lines.

Engineering & Installation Guide

For the E82EV552_4C, vertical mounting on a grounded metal backplane is mandatory to ensure effective heat dissipation. Maintain a minimum clearance of 100 mm above and below the unit for unobstructed airflow. To maintain electromagnetic compatibility (EMC), use shielded motor cables and ground the shield at both the inverter's mounting plate and the motor's terminal box using 360-degree clamps. Avoid routing low-voltage control and communication cables parallel to high-voltage power cables to prevent inductive noise interference. Before operation, ensure that all terminal connections are torqued according to specifications to prevent localized overheating and verify that the input voltage matches the 400/500 V nameplate rating.
