Lenze 8200 Vector E82EV551_2C Frequency Inverter (0.55 kW)

Product Overview

The Lenze E82EV551_2C (E82EV551K2C) is a high-performance vector-controlled frequency inverter from the established 8200 Vector series. Specifically designed for 230V three-phase applications, this 0.55 kW drive is engineered to provide precise speed and torque control for industrial machinery. The "Vector" designation indicates its ability to provide high torque even at low speeds, making it ideal for demanding applications like conveyors, fans, and assembly lines. As a compact and modular solution, the E82EV551_2C offers a balance of energy efficiency and reliable motor management, although it is important to note that this specific version is designed without integrated interference suppression measures, requiring external filtering if EMC compliance is necessary for your environment.

Technical Configuration

The E82EV551_2C hardware is built for flexibility and durability. It operates on a 3-phase 230V mains connection and is housed in a compact frame measuring 180 mm x 140 mm. The drive features a modular design that supports various plug-in functional modules for communication (such as PROFIBUS, CANopen, or RS232) and I/O expansion. Its vector control capability allows for superior dynamic response compared to standard V/f drives. Despite its robust performance, this model is currently in the Phase-Out product phase, making it a critical component for maintenance and legacy system support where identical replacements are required to maintain existing control cabinet layouts.

Technical FAQs

How do I handle EMC compliance since this drive lacks internal suppression?

Because the E82EV551_2C is manufactured without internal interference suppression, it is susceptible to emitting electromagnetic noise back into the mains. In environments where EMC standards must be met, you should install an external RFI (Radio Frequency Interference) filter on the input side and use shielded motor cables to prevent interference with sensitive electronics nearby.

Can this drive be used with a single-phase input?

The technical specification for this model explicitly states a 3 x 230 V mains connection. Using it with a single-phase input may lead to DC bus undervoltage faults or significantly derate the output power and lifespan of the internal bridge rectifier. For single-phase 230V applications, Lenze offers dedicated versions within the 8200 series.

What is the benefit of the "Vector" control in this model?

Vector control allows the E82EV551_2C to mathematically model the motor's magnetic field and current. This results in significantly better speed stability under varying loads and allows the drive to produce full rated torque even at very low frequencies (near 0 Hz), which is a major advantage over basic V/f drives.

Engineering & Installation Guide

Mounting and Cooling:

The drive's compact dimensions (18x14x8 cm) allow for space-saving mounting. However, VFDs generate heat during power conversion. Mount the unit vertically on a flat, heat-dissipating surface. Ensure there is a minimum of 100 mm clearance above and below the unit to allow for natural convection or forced airflow. If mounting multiple units in a single cabinet, verify that the total heat load does not exceed the cabinet's cooling capacity.

Wiring for Safety and Performance:

Always use a dedicated ground (PE) connection for the inverter and the motor. For the motor connection, use shielded cables with the shield grounded at both ends (using 360° EMC clamps) to minimize high-frequency radiation. The mains input should be protected by appropriate fuses or a circuit breaker sized for the 0.55 kW rated load. Given the spring or screw terminals used in the 8200 series, ensure a stripping length of approximately 8-10 mm for a secure, vibration-resistant connection.

Commissioning and Programming:

The E82EV551_2C is typically programmed using a plug-in keypad (Keypad XT) or via a PC connection with a communication module. Before running the motor, perform an "Auto-tuning" or "Motor Identification" run to allow the inverter to measure the motor's electrical characteristics (resistance and inductance). This step is vital for the Vector control algorithm to function accurately and provide the best torque performance.
