E84AVSCE4024SX0 - Frequency Converter - LENZE

Lenze 8400 StateLine E84AVSCE4024SX0, 4.0 kW frequency drive for asynchronous motors

The Lenze 8400 StateLine frequency drive, manufacturer reference E84AVSCE4024SX0, is aimed at maintenance teams, integrators and OEMs looking for a reliable drive for three-phase asynchronous motors up to 4,0 kW on 400/500 VAC supplies. Designed for general industrial applications, this model provides precise speed regulation with a range of 0 to 599 Hz and a rated current of 9,5 A. Cabinet mounting simplifies retrofits into existing panels while ensuring fast, repeatable commissioning. Standard ambient version with no integrated safety functions, suitable for PLC-driven automation architectures where safety functions are handled externally. The 8400 StateLine series is known for consistent performance in conveying, pumping and ventilation tasks, offering a stable, pragmatic solution when the aim is to control speed, reduce mechanical shocks and optimize energy use without unnecessary complexity.

Operational benefits for continuous industrial use

• Precise speed control – The 0 to 599 Hz frequency range allows fine tuning of motor speed, stabilizing production rates, improving process quality and enabling adaptation to variable recipes.
• Smooth starting and reduced stress – Drive control limits inrush currents and mechanical shocks during acceleration and deceleration, preserving gearboxes, couplings and conveyors and extending equipment service life.
• Energy optimisation – Matching motor speed to the actual process requirement significantly reduces consumption on fans and pumps, directly impacting operating costs and thermal management of installations.
• Easy cabinet integration – Built for cabinet mounting on DIN rail or baseplate depending on configuration, the E84AVSCE4024SX0 fits easily into existing racks, minimising downtime during emergency replacements.
• Ensured service continuity – Although listed as discontinued by the manufacturer at some distributors, this model remains available as new or refurbished stock, and through standard exchange or repair at SEI, with 6 to 24 months warranty depending on the service.

Key technical specifications and build quality

From the Lenze 8400 StateLine range, the E84AVSCE4024SX0 is a drive for three-phase asynchronous motors up to 4,0 kW (about 5.4 HP). It operates on 400/500 VAC supply, 3~ + PE, and delivers a rated current of 9,5 A. The 0 to 599 Hz output frequency allows a wide operating spectrum, from very low speeds up to high RPMs when the application requires. Designed for cabinet mounting, it can be installed on rail or baseplate following machine builder standards and workshop practices. This version is specified for standard ambient conditions and contains no integrated safety functions, meaning safe stop or safety torque functions must be provided by external devices if required by the risk assessment. The 8400 StateLine architecture favours operational simplicity and standardisation for typical applications, with methodical parameterisation documented in the E84AVSCx series manual. The control interface allows rational adaptation to process signals and reliable tuning of ramps, speeds and limits to achieve stable, repeatable transitions.

Typical uses and application contexts

This drive targets general industrial applications such as conveyors, pumps and ventilation, as well as auxiliary drives on packaging and handling machines. It is suitable for automated lines controlled by a programmable logic controller, where speed adjustment improves material flow control and energy efficiency. The E84AVSCE4024SX0 is relevant when reliable regulation of asynchronous motors is required without the complexity of a servo drive, while integrating into an existing digital control or automation architecture.

Differentiation, longevity and service guarantees

The Lenze 8400 StateLine series has been widely deployed for its balance of performance, simplicity and robustness in standard use. The reference E84AVSCE4024SX0, sometimes marked as discontinued by the manufacturer, remains practicably usable thanks to available stocks and refurbished units on the market. Standard Exchange Industry supports the longevity of your installations with options for new or refurbished supply, standard exchange and repair, with a 6 to 24 months warranty depending on the chosen service.
