E84AVTCE2512SX0 - Frequency Converter - LENZE

LENZE E84AVTCE2512SX0, 8400 series frequency inverter for precise speed control

The frequency inverter LENZE E84AVTCE2512SX0 is aimed at maintenance managers, automation engineers and integrators seeking a reliable drive for varying the speed of asynchronous motors in industrial environments. From the 8400 family by LENZE, it addresses common power conversion and motor control needs in continuous or cyclic applications, with a clear objective: stabilise speed, protect the motor and optimise electrical consumption. This model stands out for its compactness, structured parameter logic and protection features that secure equipment and process. It integrates naturally into an automation architecture controlled by a programmable logic controller or numerical control, making modernisation straightforward, including drop-in replacements for existing devices.

Operational benefits for your drive applications

• Speed stability – Precise regulation to maintain consistent speeds, improve product quality and reduce process drift.
• Controlled start and stop – Configurable acceleration and deceleration ramps to limit mechanical shocks and wear on transmission components.
• Energy optimization – Frequency adjusted closely to the demand, with measurable consumption reductions on conveyors, pumps and fans.
• Easy integration – Seamless exchange with your PLC via control I/Os and communication modules available within the range, for straightforward supervision.
• Predictable maintenance – Clear diagnostic and alarm functions to anticipate faults and reduce mean time to repair.

Architecture and key technical features

Designed for speed variation of three-phase asynchronous motors, the E84AVTCE2512SX0 implements conversion via IGBT bridges and PWM modulation, delivering an output voltage and frequency adapted to the targeted operating point. The 8400 platform favours methodical commissioning, with a logical parameter structure and assistants that guide the adjustment of ramps, current limits and protection thresholds. Control modes available within the family, such as V/f or open-loop vector control depending on the selected variant, provide reliable torque at low speed and satisfactory transient behaviour. The device is engineered for EMC compatibility in industrial environments, subject to wiring conforming to LENZE recommendations and the use of suitable accessories. Integrated protections typically cover overloads, DC bus overvoltage, overtemperature and control faults, with timestamping and readable event codes to speed up on-site diagnostics. In terms of interfaces, the 8400 family provides digital inputs/outputs for run, stop, direction and reset commands, as well as analog inputs for the speed reference. Communication cards are available in the range for integration with major industrial fieldbus systems. Depending on configuration, motor adaptation assistants and preconfigured application profiles can be enabled to reduce setup time and improve repeatability from machine to machine.

Typical uses and application contexts

The E84AVTCE2512SX0 is suitable for processes requiring robust, repeatable speed variation. It is commonly used on conveyors, pumping and ventilation systems, packaging tables, dosing units, auxiliary rewinders, as well as feed axes within lines controlled by numerical control. For retrofits, it provides a practical replacement for an existing frequency inverter while maintaining the architecture around the programmable logic controller and plant network. For new projects, its reduced footprint and flexible parameterisation simplify panel integration and fleet standardisation.

8400 family reliability, LENZE support and SEI reassurance

LENZE's 8400 family is widely deployed in industry, which facilitates maintenance throughout the lifecycle. Clear documentation and the availability of accessories contribute to stable operation, even in demanding environments. Standard Exchange Industry reinforces this reliability with services aligned to production needs: reconditioned units tested on bench, standard exchange for rapid restart, or repair when hardware continuity is the priority. Each unit processed undergoes electrical and functional checks under load, with a test report for objective traceability. Warranty is tailored to the chosen service, ranging from 6 to 24 months, and shipping is provided within 24 to 72 h to your production sites.

To confirm electrical and mechanical compatibility, the rated values for input voltage, output voltage and frequency, power and current must be verified on LENZE documentation specific to the E84AVTCE2512SX0 reference. Depending on the selected variant within the 8400 family, control modes may include V/f and open-loop vector control, and integration into automation architectures is achieved via hardwired I/Os or communication cards from the family. This approach avoids undersizing or oversizing risks and ensures compliance with applicable EMC and safety rules on site.

In practice, this frequency inverter delivers a direct gain in mechanical component lifetime thanks to gradual speed profiles, a reduction of inrush current at start-up and the adaptation of consumption to load. It helps stabilise product quality by maintaining consistent linear speeds on conveyors, limits hydraulic shocks in pumps and reduces noise and wear in ventilation systems. From a maintenance standpoint, clear access to states, faults and histories enables fast analysis, whether by your in-house team or during an intervention by our technicians.
