Lenze EVF8246-E-V921 8200-series Variable Frequency Drive

Description

Engineered for precise speed and torque control of three-phase asynchronous motors, the Lenze EVF8246-E-V921 is a high-performance frequency inverter belonging to the modular 8200-series family. This variable frequency drive is designed to optimize energy consumption and process efficiency in demanding industrial environments, delivering a rated power output of 11 kW at 480 V.

The modular architecture of the EVF8246-E-V921 allows for flexible integration with various pluggable communication and I/O modules, making it highly adaptable to existing control cabinet configurations. Although officially classified as a phase-out model since 2017, this robust drive remains a critical spare part for maintaining and extending the lifecycle of legacy automation systems.

Features

• Modular design supporting plug-in communication modules (such as CAN, PROFIBUS, or Interbus).
• Configurable V/f characteristic control (linear or quadratic) for versatile motor adaptation.
• Integrated motor overload protection and thermal monitoring to prevent equipment damage.
• Compact bookstyle housing designed for space-saving side-by-side mounting in control cabinets.
• High overload capacity to handle demanding starting torques and transient load spikes.

Applications

• Conveyor and material handling systems.
• Industrial pumps, fans, and ventilation systems.
• Packaging machinery and automated assembly lines.
• General mechanical engineering and process control applications.

Technical Specifications

Installation Guidelines

• Mounting Orientation: Install the drive vertically on a flat, thermally conductive mounting plate inside a control cabinet.

• Clearance: Maintain a minimum clearance of 100 mm above and below the unit to ensure unobstructed convective airflow and cooling.

• Shielding and Grounding: Use shielded motor cables with low-impedance 360-degree EMC shielding connections at both the drive and motor ends to minimize electromagnetic interference.

• Ambient Temperature: Ensure the operating environment does not exceed the specified limits (typically up to 40 degC without derating).
