E82EV551_4C Lenze 8200-series 0.55 kW Vector Frequency Inverter

Product Overview

The E82EV551_4C (E82EV551_4C) is a high-precision vector frequency inverter from the Lenze 8200-series, engineered to provide dynamic speed and torque control for 3-phase asynchronous motors. Delivering a rated power of 0.55 kW, this drive is a standard component for low-power B2B applications such as small-scale conveyor systems, dosing pumps, and automated laboratory equipment. The E82EV551_4C is designed for 3-phase mains connections of 400 to 500 V and belongs to the "Without Interference Suppression" variant, making it an ideal choice for installation in control cabinets that utilize a centralized, system-wide EMC filter. Although the 8200-series reached its phase-out milestone in 2017, this German-engineered drive remains a highly reliable and cost-effective solution for maintaining and optimizing legacy industrial infrastructure where high-resolution vector control and compact dimensions are required.

Technical Configuration

The E82EV551_4C (also cataloged as E82EV551K4C) is architected for space-efficient cabinet integration, featuring a slim 7.60 cm wide chassis and a total weight of 1.00 kg. The unit utilizes sensorless vector control to maintain exceptional speed stability and high starting torque, ensuring precise motor regulation even under varying load conditions. Its modular hardware design includes a standard AIF (Automation Interface) slot, allowing for the rapid addition of fieldbus communication modules (such as CAN, PROFIBUS, or RS485) or localized I/O expansions. The power stage is designed for 400/500 V operation and includes comprehensive protection logic against overvoltage, earth faults, and motor thermal overload, providing the durability necessary for continuous operation in professional manufacturing and processing lines.

Technical Specifications

Technical FAQs

What is the benefit of using the "Without Interference Suppression" version?

This version lacks an internal mains filter, which significantly reduces the internal heat signature and leakage current of the drive. It is specifically designed for systems where an external central filter manages EMC for multiple devices, or for use in industrial environments where high-sensitivity RCDs are present.

Can the E82EV551_4C be used for high-precision positioning?

While the 8200-series is primarily a frequency inverter for speed control, its vector control capabilities allow for very accurate speed regulation. For high-precision positioning or synchronized multi-axis camming, the Lenze 9300-series or newer i950 series is generally recommended.

How do I transfer parameters from a faulty unit to a new E82EV551_4C?

Parameters can be easily transferred using the plug-in EMZ8201BB keypad module's copy function or via a PC link using Lenze Global Drive Control (GDC) software. This ensures that the replacement drive perfectly matches the original motor's torque and speed curves.

What are the recommended operating temperatures for this 0.55 kW drive?

The drive is typically rated for operation between 0 and 45 deg Celsius without derating. For installations in warmer environments, ensure adequate forced-air ventilation within the control cabinet to prevent thermal tripping.

Engineering & Installation Guide

For the E82EV551_4C, a vertical mounting orientation on a grounded metal backplane is mandatory to ensure effective cooling through the internal heat sink. Maintain a minimum clearance of 100 mm above and below the unit for unobstructed airflow. Since this model does not include internal EMC suppression, the use of shielded motor cables is mandatory to prevent electromagnetic noise from affecting nearby sensors or controllers; ground the shield at the inverter’s EMC plate using 360-degree clamps. During commissioning, utilize the "Auto-tuning" feature to identify the motor's electrical parameters; this step is essential to ensure the vector control algorithm provides maximum efficiency and torque stability at the rated 0.55 kW output.
