EVF8213-E Lenze 8200-Series Vector Frequency Inverter 2.2 kW

Product Overview

The EVF8213-E (EVF8213E) is a high-performance 8200-series variable frequency drive (VFD) engineered for precise speed and torque control of three-phase asynchronous motors. Rated at 2.2 kW (3.0 HP) with a 460V input capacity, this inverter is a critical component for optimizing power consumption and mechanical longevity in industrial pump, fan, and conveyor systems. Its robust vector control architecture ensures consistent motor performance even under varying load conditions, effectively reducing mechanical stress and preventing unplanned downtime. The EVF8213-E is designed for cabinet mounting, featuring a slim profile that maximizes space efficiency in complex automation panels. As a proven solution within the Lenze ecosystem, it provides the reliability required for continuous-duty production environments where stable frequency modulation is non-negotiable.

Technical Configuration

The EVF8213-E utilizes Lenze’s modular "Global Drive" concept, allowing for easy adaptation to different communication protocols through plug-in modules. The internal power electronics are optimized for high-frequency switching, which minimizes motor noise and thermal losses. The drive features a comprehensive suite of I/O, including programmable analog inputs and digital terminals for remote start/stop and frequency setpoint control. Advanced protective functions, such as phase-failure monitoring, I2t motor protection, and short-circuit detection, are standard. The unit also supports DC braking and S-ramp acceleration profiles, providing smooth motion control for sensitive material handling applications.

Technical Specifications

Technical FAQs

Can the EVF8213-E be configured without a keypad?

Yes, while a plug-in keypad (EMZ8201BB) is common for manual tuning, the EVF8213-E can be fully parameterized via a PC using the LECOM-B (RS485) interface and Lenze GDC software.

What should I check if I encounter a 'LU' (Low Voltage) trip?

An 'LU' trip indicates the DC bus voltage has fallen below the safety threshold. Check the incoming three-phase supply for dropped phases or significant voltage sags, and ensure that the input terminals are tightened to prevent high-resistance connections.

Does this drive support energy recovery during braking?

The EVF8213-E does not inherently support regenerative braking to the grid. For high-inertia loads that require rapid deceleration, an external braking resistor must be connected to the dedicated terminals to dissipate energy as heat.

Engineering & Installation Guide

• Heat Management: The 2.2 kW power stage generates heat during operation. Mount the unit vertically on a flat, thermally conductive surface. Ensure a minimum clearance of 100 mm at the top and bottom to facilitate natural convection or forced-air cooling through the integrated heatsink.

• Shielding and Grounding: To minimize EMI/RFI, motor cables must be shielded. The shield should be grounded at both the inverter end (using the EMC plate) and the motor terminal box. Keep control cables (0-10V / 4-20mA) in separate conduits from high-power AC lines to prevent signal interference.

• Phase-Out Maintenance: As this unit is in the Phase-Out stage, it is recommended to maintain a backup of the parameter set (bin file). If a unit fails, the parameters can be quickly uploaded to a replacement EVF8213-E, reducing the Mean Time to Repair (MTTR) from hours to minutes.
