Variateur de fréquence Lenze 8400 StateLine E84AVSCE7524VX0 7,5 kW

Product Overview

The E84AVSCE7524VX0 (E84AVSCE7524VX0) is a high-efficiency frequency inverter from the Lenze 8400 StateLine series, specifically engineered to provide superior motion control for 3-phase asynchronous motors. Delivering a robust 7.5 kW rated power, this drive is a primary choice for B2B applications such as decentralized conveyor systems, palletizers, and high-performance fan arrays in power plants and manufacturing facilities. The E84AVSCE7524VX0 features integrated interference suppression measures (EMC filters), ensuring stable operation without disrupting sensitive nearby digital controllers or sensor networks. Designed for mains connections of 3 x 400 / 500 V, this German-engineered unit provides the precise speed regulation and torque stability required to reduce mechanical wear and optimize energy consumption in demanding industrial automation environments.

Technical Configuration

The E84AVSCE7524VX0 is built on the Lenze "L-force" platform, which emphasizes modularity and ease of integration. As a StateLine variant, it bridges the gap between basic motor control and complex positioning, offering integrated brake management and a wide range of programmable I/O. The hardware supports a 3-phase input of 400 to 500 VAC and is housed in a compact chassis (24.00 x 14.00 x 12.50 cm) that maximizes cabinet density while maintaining efficient thermal dissipation. Communication is handled via a standard integrated system bus (CANopen), with additional fieldbus modules available for PROFINET or EtherCAT. The drive’s architecture is optimized for high dynamic response, allowing it to handle sudden load changes with minimal speed deviation, making it an essential component for high-throughput production lines.

Technical Specifications

Technical FAQs

What are the primary differences between the StateLine (SCE) and HighLine (HCE) 8400 models?

The StateLine (E84AVSCE7524VX0) is optimized for sophisticated speed control and point-to-point motion tasks. While the HighLine series adds more advanced positioning and synchronization features, the StateLine is the cost-effective standard for most industrial conveyor and pump applications.

Can the E82EV222_4C be used in 500 V power grids?

Yes. The E84AVSCE7524VX0 is rated for a 3-phase input of up to 500 VAC. This makes it a versatile solution for international machinery exports, as it can operate seamlessly across different regional industrial voltages.

How does the integrated interference suppression benefit the installation?

The built-in filters meet standard industrial EMC requirements (Class A), reducing the need for external line filters. This saves significant space on the DIN rail and simplifies the overall wiring of the control cabinet.

What software is required for parameterizing this drive?

The 8400-series is typically configured using the "L-force Engineer" software. This tool allows for intuitive drag-and-drop parameterization, diagnostic monitoring, and firmware updates via the CANopen or USB interface.

Engineering & Installation Guide

For the E84AVSCE7524VX0, ensure a vertical mounting orientation in the control cabinet to allow the internal fans to move air effectively through the power stage. Maintain a clearance of at least 100 mm above and below the unit. Since this model includes integrated interference suppression, it is critical to ground the inverter’s mounting plate to the cabinet backplane using a large-surface conductive connection to ensure the filter operates effectively. Use shielded motor cables for all installations, and ground the shield at both the drive and the motor terminal box using 360-degree clamps. During commissioning, perform a motor parameter identification (auto-tuning) to calibrate the V/f or vector control curves to the specific electrical characteristics of your motor, which is essential for maximizing torque efficiency at 7.5 kW loads.
