Variateur de fréquence vectoriel Lenze E82EV752_4C série 8200 7,5 kW

Product Overview

The E82EV752_4C (E82EV752K4C) is a high-capacity 8200-series vector frequency inverter engineered by Lenze for rigorous motor control applications requiring up to 7.5 kW (10 HP) of power. Operating on a 400 / 500 VAC three-phase supply, this drive is a cornerstone for heavy-duty industrial machinery, including large-scale pumping stations, high-torque industrial mixers, and synchronized conveyor lines in manufacturing plants. The "4C" designation indicates the integration of built-in interference suppression filters, which safeguard the drive against electromagnetic noise and ensure the integrity of neighboring control signals. With its robust 5.00 kg frame and optimized vector control characteristics, the E82EV752_4C minimizes mechanical stress and maximizes energy efficiency, even in the demanding environments of the global B2B sector. Although it has reached phase-out status, it remains an essential component for the maintenance and optimization of legacy automation infrastructure.

Technical Configuration

The E82EV752_4C utilizes a sophisticated vector control architecture that provides high starting torque and precise speed regulation, even under fluctuating load conditions. This "Global Drive" platform features a modular slot for fieldbus communication, supporting protocols such as PROFIBUS, CANopen, and LECOM-B to facilitate seamless SCADA integration. The hardware includes a comprehensive suite of protective functions, such as I2t motor monitoring, short-circuit detection, and overvoltage protection. Its power stage is designed for high reliability, capable of handling significant transient overloads. The unit's firmware allows for advanced parameterization of acceleration/deceleration S-ramps and DC injection braking, providing the mechanical smoothness required for sensitive industrial processes.

Technical FAQs

Does the E82EV752_4C support regenerative braking for high-inertia loads?

The drive includes an internal brake chopper; however, for applications with significant regenerative energy (like large centrifugal fans), an external braking resistor must be connected to the terminals to dissipate the energy as heat and prevent 'OU' (Overvoltage) trips.

What is the primary difference between the 8200-series and 9300-series?

The 8200-series is a versatile frequency inverter primarily designed for standard asynchronous motor speed control. In contrast, the 9300-series is a dedicated servo system designed for high-dynamic positioning and synchronous motor control.

Can I operate this 7.5 kW drive at a higher ambient temperature?

Yes, it can operate up to 55 deg C, but you must apply a current derating of approximately 2.5% per degree Celsius above 45 deg C to protect the internal power electronics from thermal stress.

Engineering & Installation Guide

• Cooling and Airflow: Due to the 7.5 kW power rating, this unit generates substantial heat. It must be mounted vertically on a flat, non-flammable surface. Ensure a minimum clearance of 100 mm at the top and bottom of the unit to allow for unimpeded airflow through the heatsink.

• EMC-Compliant Wiring: To maintain the effectiveness of the integrated interference suppression, use only shielded motor cables. The shield must be connected to the PE rail using a 360-degree conductive clamp. Avoid pigtail grounding, as this increases high-frequency impedance and reduces EMC performance.

• Safety Discharge Time: The internal DC bus capacitors store a lethal charge. After disconnecting the 400/500 V mains supply, wait at least 10 minutes before touching any terminals. Always verify that the voltage across +UG and -UG is below 50 VDC using a certified multimeter before beginning work.
