Variateur de fréquence triphasé 460 V Lenze série 8200 EVF8214-E

Product Overview

The EVF8214-E (EVF8214-E) is a high-performance 3-phase frequency inverter from the Lenze 8200-series, engineered to provide precise speed and torque control for asynchronous motors in demanding B2B industrial environments. Operating at a rated voltage of 460 V, this drive delivers a substantial output power of 52 kVA, making it a critical asset for heavy-duty production lines, large-scale conveyor systems, and complex process control applications. The EVF8214-E is designed to bridge the gap between robust power delivery and fine-tuned motor management, ensuring consistent performance and high energy efficiency. Although the 8200-series is currently in its phase-out stage, this German-engineered drive remains a benchmark for reliability and integration flexibility, providing a dependable solution for maintaining legacy infrastructure while optimizing operational throughput.

Technical Configuration

The EVF8214-E (identified by secondary item code 33.8214_E) features a robust hardware architecture optimized for high-voltage industrial grids. Housed in a chassis measuring 22.90 x 10.20 x 27.90 cm and weighing 2.90 kg, it is designed for space-efficient cabinet mounting without compromising on thermal stability. The drive utilizes a modular AIF (Automation Interface) slot, allowing for the seamless addition of communication modules (such as CAN, PROFIBUS, or RS485) and I/O expansions to meet specific system requirements. Its power stage is built to handle the rigorous duty cycles of industrial process control, featuring integrated monitoring for overvoltage, earth faults, and motor thermal protection. This configuration ensures that the EVF8214-E can maintain stable frequency output even under fluctuating load conditions common in heavy manufacturing and power plant environments.

Technical FAQs

How do I manage the communication setup for the EVF8214-E?

The EVF8214-E utilizes a modular slot on the front of the unit. To integrate it into a networked system, you must plug in the appropriate 8200-series communication module (e.g., E82ZAFCC for CAN or E82ZAFPC for PROFIBUS). Once inserted, the drive parameters can be accessed via the network or through a plug-in keypad.

Is the EVF8214-E suitable for high-torque startup loads?

Yes. The 8200-series architecture is designed to provide significant breakaway torque. To maximize this, it is recommended to perform an "Auto-tuning" run during commissioning so the inverter can precisely map the motor's electrical characteristics and optimize the V/f or vector control curves.

What is the recommended replacement path for this 52 kVA phased-out model?

For maintaining existing systems, original new or refurbished EVF8214-E units are the preferred choice to ensure mechanical and electrical drop-in compatibility. For long-term facility upgrades, the Lenze i550 series is the modern successor, though it will require a review of cabinet space and communication protocol mapping.

Engineering & Installation Guide

For the EVF8214-E, vertical mounting on a grounded metal backplane is mandatory to facilitate the "chimney effect" for efficient heat dissipation. Ensure a minimum clearance of 100 mm above and below the unit to prevent thermal derating. To maintain electromagnetic compatibility (EMC) in a 460 V environment, use shielded motor cables and ensure the shield is grounded with a 360-degree clamp at the drive's EMC plate. Avoid routing low-voltage control signal wires parallel to high-voltage 460 V cables to prevent inductive noise interference. Before initial power-up, verify that the mains voltage matches the nameplate specifications and ensure that all terminal screws are torqued correctly to prevent high-resistance contact points that can lead to localized overheating.
