E84AVHCE5514SB0 Lenze 8400-series 0.55 kW HighLine Frequency Inverter

Product Overview

The E84AVHCE5514SB0 (E84AVHCE5514SB0) is a high-performance AC drive from the Lenze 8400 HighLine series, engineered to provide precision motion control for demanding industrial applications. Delivering a rated power of 0.55 kW, this inverter is designed for 3-phase mains connections of 400 to 500 V. In B2B sectors such as decentralized materials handling, high-speed intralogistics, and automated assembly, the E84AVHCE5514SB0 excels due to its integrated Safe Torque Off (STO) system, which meets stringent international safety standards. This HighLine variant is specifically optimized for applications requiring point-to-point positioning and high dynamic response. By utilizing this drive, system integrators achieve a sophisticated balance of energy efficiency and operational safety, ensuring maximum machine uptime and reduced total cost of ownership in modern manufacturing environments.

Technical Configuration

The E84AVHCE5514SB0 is built on a modular hardware architecture that prioritizes functional safety and versatile connectivity. As a HighLine model, it includes advanced features such as integrated positioning control and a wide range of supported fieldbus systems through plug-in modules, including EtherCAT, PROFINET, and PROFIBUS. The drive’s hardware supports a variety of feedback systems, allowing it to manage complex motion profiles with millisecond accuracy. Its compact 21.4 x 21.7 x 7 cm chassis is designed for space-efficient cabinet installation, featuring forced-air cooling to maintain thermal stability during continuous operation. The integrated STO functionality allows for the immediate removal of motor torque without the need for redundant external power contractors, significantly simplifying the safety circuit design for OEMs and system integrators.

Technical FAQs

What is the advantage of the HighLine series over the StateLine or BaseLine models?

The HighLine series, including the E84AVHCE5514SB0, is specifically designed for applications involving positioning. It features integrated motion control logic that allows for point-to-point positioning and synchronized movement, which are typically not available in the lower-tier 8400 models.

How does the integrated STO (Safe Torque Off) benefit my machine design?

The integrated STO removes the need for two separate contactors to safely disconnect the motor from the power supply during a safety event. This reduces cabinet space, lowers hardware costs, and simplifies the wiring for your safety PLC or emergency stop circuits.

Can I use this drive for global exports to 500 V regions?

Yes. The E84AVHCE5514SB0 is rated for operation on 3-phase networks between 400 V and 500 V. This flexibility makes it an ideal choice for machine builders exporting to diverse international markets without requiring different drive variants.

Engineering & Installation Guide

For the E84AVHCE5514SB0, a vertical mounting orientation is required to ensure that the forced-air cooling system can effectively dissipate heat from the 0.55 kW power stage. Maintain a minimum clearance of 100 mm above and below the unit. To maintain the integrity of the integrated safety system, ensure that the STO terminals are wired according to the specified SIL/PLe safety standards and that the 24 VDC auxiliary supply is stable. All motor cables must be shielded, and the shield should be grounded using a 360-degree clamp at the inverter’s EMC plate to prevent electromagnetic interference from disrupting the high-resolution positioning feedback. During commissioning, utilize the "L-force Engineer" software to perform an automatic motor parameter identification run, which is essential for the drive to calculate the precise motor model required for accurate positioning tasks.
