Product Overview

The E82EV551K4C200 (E82EV551-4C200) is a vector-controlled frequency inverter from the Lenze 8200-series, engineered for reliable motor speed regulation in industrial automation. Rated at 0.55 kW and designed for 3 x 400/500 V supply networks, this compact drive provides precise torque and speed control for light-duty applications, including small conveyor systems, automated dosing pumps, and fan control. Its robust vector algorithm ensures high dynamic performance, allowing for consistent operation in production environments where motor efficiency and process stability are required to maintain overall equipment effectiveness.

Technical Configuration

This vector inverter is designed for vertical cabinet installation, allowing for effective thermal management within standard industrial enclosures. The unit provides advanced monitoring capabilities for operational safety, including protection against over-voltage, under-voltage, and motor overload conditions. Unlike variants with internal filtering, this specific model (E82EV551K4C200) allows for flexible integration into installations where external EMC filtering may be centrally managed or specifically engineered to meet site-wide compliance standards. It supports standard digital and analog I/O for integration into local control circuits and is compatible with modular fieldbus extensions for enhanced networking capabilities in larger automation systems.

Technical Specifications

FAQs

Does this inverter require an external EMC filter?

This model is supplied without integrated interference suppression. Depending on your local regulations and the proximity of other sensitive electronic equipment, you may need to install an external EMC filter to comply with industrial noise emission standards.

Is the E82EV551K4C200 suitable for high-starting torque applications?

Yes, as a vector drive, it is capable of providing higher starting torque compared to standard V/f inverters, making it suitable for loads that require reliable startup under load.

What is the impact of the 'Phase-Out' status on my project?

The phase-out status means this model is no longer in active production. We recommend using it for maintenance of existing legacy systems; for new machine designs, we advise consulting with Lenze for current-generation drive alternatives.

Can I run a single-phase motor with this 3-phase drive?

No, this inverter is designed exclusively for use with 3-phase asynchronous AC motors. Connecting a single-phase motor will cause drive instability and potential hardware failure.

Installation Guidelines and Best Practices

• Thermal Clearance: Despite its small power rating, the drive must have at least 100 mm of clearance above and below to allow for natural convection cooling. Ensure the air intake at the bottom is not blocked by cable ducting or other components.

• Grounding: Although this model lacks integrated suppression, proper grounding remains essential. Ensure the drive chassis is securely bonded to the cabinet's protective earth (PE) busbar using a low-impedance connection to ensure safe operation and reduce common-mode noise.

• Motor Cabling: Use shielded motor cables, even in this lower power range. Connect the shield to the drive’s earth plate or a dedicated EMC gland to minimize electromagnetic noise coupling to nearby control signal lines.
