E84AVTCE3712SX0- Frequency Converter - LENZE

LENZE E84AVTCE3712SX0, 8400 series, frequency inverter for reliable control of asynchronous motors

Designed for demanding industrial environments, the E84AVTCE3712SX0 frequency inverter is part of the LENZE 8400 series, a family recognized for regulation stability, consistent software and straightforward panel integration. This model is aimed at maintenance teams, system integrators and engineering offices looking for a durable solution to control asynchronous motor speed, reduce mechanical stress and optimize process energy consumption. In the context of equipment modernization or like-for-like replacement to manage obsolescence, this drive provides a structured commissioning framework, clear diagnostic functions and natural compatibility with automation architectures controlled by a programmable logic controller. It integrates smoothly into lines where frequency inverters and servo drives coexist, while ensuring measurable and repeatable production continuity.

Operational benefits for your drive applications

• Production continuity – Stable speed regulation to limit unplanned stops, with configurable acceleration and deceleration ramps to protect mechanical components.
• Streamlined commissioning – Guided parameter setting and consistent menu logic across the 8400 series reduce on-site familiarization time and simplify replacements.
• Process quality – Control of speed and torque improves cycle repeatability on conveyors, pumps, fans and packaging equipment.
• Integration flexibility – Clear terminal layout, standard I/O and communication options available by version for direct connection to existing automation networks.
• Predictable maintenance – Built-in diagnostic and monitoring tools useful for fault analysis, planning scheduled stops and reducing restart time.

Technical design focused on reliability and cabinet integration

The LENZE E84AVTCE3712SX0 frequency inverter features a robust design suited for industrial enclosures. Wiring ergonomics and terminal arrangement contribute to a clear installation, while airflow routing and thermal management are designed to ensure dissipation in a controlled environment. The 8400 series software architecture provides a uniform framework for configuring key parameters, with a hierarchy that eases navigation and duplication of settings from one machine to another. Motor protection and status monitoring functions support the longevity of the entire drive system. Communication components are available depending on the series' versions and options, allowing the drive to be aligned with the site's network architecture without forcing redesigns. Detailed electrical specifications such as input and output voltage, power range in kW and CV, control modes and communication protocols must be confirmed against the E84AVTCE3712SX0 reference and the nameplate in place to guarantee a precise match with your motor and network.

Target industrial applications

The E84AVTCE3712SX0 naturally fits on intra-logistics conveyors, pumping and ventilation systems, packaging and material handling lines, as well as auxiliary axes of machine tools with numerical control (CNC). In these contexts, stable speed regulation supports production quality, mechanical protection of the motor fleet and energy optimization. Compatibility with various programmable logic controllers facilitates integration into heterogeneous architectures.
