Variateur de fréquence vectoriel Lenze série 9300 EVF9324-EVV100 3,0 kW

Product Overview

The EVF9324-EVV100 (EVF9324-EVV100) is a high-performance vector-controlled frequency inverter from the Lenze 9300-Series, engineered to deliver precise speed regulation and high dynamic response for three-phase asynchronous motors. Delivering a rated power of 3.0 kW, this drive is a versatile solution for industrial applications such as mid-sized conveyor belts, automated packaging machinery, and centrifugal pump control. This "EVV" variant is specifically designed without integrated interference suppression measures, making it an ideal choice for installation in control cabinets that already utilize centralized EMC filtration or in environments where low-leakage current is a priority. Despite its phase-out status, the EVF9324-EVV100 remains a critical component for maintaining and optimizing legacy 9300-Series automation lines, providing the German-engineered durability and torque stability required for modern manufacturing standards.

Technical Configuration

The EVF9324-EVV100 is architected for a 3-phase mains connection of 400 to 480 V, ensuring global compatibility with various industrial power grids. It utilizes advanced sensorless vector control to maintain exceptional torque linearity, even at low speeds, which is essential for applications requiring smooth startup and precise speed maintenance under load. The hardware features a modular interface design, allowing for the integration of fieldbus communication modules (PROFIBUS, INTERBUS, or CANopen) to facilitate its role as a communicative node within a larger PLC or DCS architecture. Its compact 9.70 cm wide chassis and 5.00 kg build are optimized for vertical mounting, featuring integrated thermal management to ensure continuous 3.0 kW performance in enclosed industrial cabinets.

Technical FAQs

What is the significance of the "Without Interference Suppression" designation for a 3.0 kW drive?

This model lacks an internal mains filter, which is advantageous in systems where a single, large external filter is used for the entire control cabinet. This reduces the leakage current of the individual drive and can prevent nuisance tripping of high-sensitivity residual current devices (RCDs) in certain electrical installations.

Can the EVF9324-EVV100 be used for high-precision positioning tasks?

While the EVF series is primarily a frequency inverter for speed and torque control, the 9300-Series architecture allows for significant control flexibility. However, for true high-precision positioning or camming, the EVS (Servo) variants of the 9300-Series are typically more suitable.

How do I transfer parameters to a replacement EVF9324-EVV100?

Parameters can be transferred using the plug-in EMZ9371BC keypad module or via a PC link using Lenze Global Drive Control (GDC) software. It is recommended to back up your parameter sets digitally to ensure rapid restoration during maintenance procedures.

Engineering & Installation Guide

For the EVF9324-EVV100, proper mounting is essential; install the unit vertically in a well-ventilated control cabinet with a minimum clearance of 100 mm above and below the chassis. Since this model does not have internal suppression, the use of shielded motor cables is mandatory to maintain electromagnetic compatibility (EMC). Ground the cable shield with a 360-degree clamp at the inverter’s EMC plate to minimize radiated noise. To protect the 3.0 kW power stage from mains transients, the installation of a line reactor is highly recommended. During initial commissioning, utilize the "Auto-tuning" feature to calibrate the drive to the specific electrical characteristics of the motor, ensuring the vector control algorithm provides maximum efficiency and stable torque delivery throughout the speed range.
