Variateur AC 480 V 5 HP Lenze série 8200 EVF8241-E

Product Overview

The EVF8241-E (EVF8241-E) is a high-performance AC drive from the established Lenze 8200-series, engineered to provide precise speed and torque regulation for three-phase asynchronous motors. Delivering a power capacity of 5HP and rated for 480V mains connections, this drive is a cornerstone for industrial applications such as mid-sized conveyor systems, industrial fans, and centrifugal pumps. In B2B manufacturing environments, the EVF8241-E is valued for its robust German engineering and its ability to maintain consistent motor performance under varying load conditions. Although the 8200-series has entered its official phase-out stage, this model remains a critical component for maintaining and optimizing legacy automation lines, offering a reliable path for energy savings and enhanced operational control without the immediate need for a complete system overhaul.

Technical Configuration

The EVF8241-E (also cataloged under item code 33.8241_E) is architected for 480V, 50/60Hz power systems, featuring an efficient 1.5A current rating. The hardware is designed for space-conscious cabinet installation, with dimensions of 17.00 x 24.00 x 15.00 cm and a weight of 4.08 kg. Its modular interface slot allows for the integration of various function modules, including fieldbus communication (CAN, PROFIBUS) and localized I/O expansion. The drive includes integrated monitoring for overvoltage, earth faults, and motor thermal protection, ensuring long-term system reliability. Its power stage is optimized for high dynamic response, facilitating smooth acceleration ramps and precise frequency control up to the high-speed industrial ranges required for modern manufacturing processes.

Technical Specifications

Technical FAQs

Can the EVF8241-E be integrated into a networked control system?

Yes. While the base unit provides standard terminal control, it features a modular slot on the front that accepts various 8200-series communication modules (AIF). This allows for integration into PROFIBUS, CANopen, or RS485 networks for centralized control by a PLC or DCS.

What should be considered regarding its "Phase-Out" status?

The phase-out status indicates that the 8200-series is reaching the end of its official production lifecycle. However, original stock and refurbished units remain available to support existing machinery. For new project designs, mapping these specifications to the newer Lenze i550 series is typically recommended.

Is this drive suitable for high-torque startup applications?

Yes. The 8200-series is designed to provide high breakaway torque, making it suitable for applications like loaded conveyors or mixers. To maximize this performance, an automatic motor parameter identification run should be performed during commissioning.

Engineering & Installation Guide

To ensure the longevity of the EVF8241-E, it must be mounted vertically in a dry, ventilated control cabinet. Maintain a minimum vertical clearance of 100 mm to facilitate proper heat dissipation from the 5HP power stage. For electromagnetic compatibility (EMC), all motor cables must be shielded, with the shield grounded at both the inverter's mounting plate and the motor's terminal box using 360-degree clamps. Avoid routing low-voltage control signal wires parallel to high-voltage power cables to prevent inductive noise interference. During setup, utilize the plug-in keypad or GDC software to input the motor nameplate data accurately; this ensures the internal V/f or vector control algorithms are perfectly tuned to the motor's electrical characteristics, preventing nuisance overcurrent trips during rapid speed transitions.
