E84AVHCE1524SB0 Lenze 8400 HighLine 1.5 kW Frequency Inverter

Product Overview

The E84AVHCE1524SB0 (E84AVHCE1524SB0) is a premium frequency inverter from the Lenze 8400 HighLine series, specifically engineered to provide high-level motion control and integrated safety for demanding industrial applications. Delivering a rated power of 1.5 kW, this drive is a cornerstone for synchronized processing lines, such as pick-and-place robotics, palletizers, and precise material handling systems. The "HighLine" designation signifies an advanced feature set that includes point-to-point positioning and support for complex motion profiles. A critical feature of this model is the integrated Safe Torque Off (STO) system, which allows for functional safety compliance without the need for redundant external contactors. Manufactured in Germany, the E84AVHCE1524SB0 offers a robust, high-performance solution that reduces cabinet space requirements while maximizing machine safety and operational uptime in 24/7 manufacturing environments.

Technical Configuration

The hardware architecture of the E84AVHCE1524SB0 is designed for a 3-phase mains connection of 400 to 500 VAC. The HighLine variant is distinguished by its sophisticated internal bus system and memory management, capable of storing multiple parameter sets for fast machine changeovers. It features integrated interference suppression (EMC filters) to ensure stable operation in electromagnetically noisy environments. The drive’s control logic supports a wide variety of feedback systems and communication protocols through modular interface slots. The integrated STO safety function is certified to high global standards (up to SIL 3 / PL e), ensuring that the motor can be brought to a torque-free state safely during emergency stops or maintenance interventions. Its compact form factor (3.18 kg) is optimized for high-density cabinet mounting, utilizing advanced thermal management to maintain a 1.5 kW output even under continuous industrial loads.

Technical Specifications

Technical FAQs

What are the primary advantages of the "HighLine" version over the standard 8400 BaseLine?

The HighLine version, such as the E84AVHCE1524SB0, includes integrated positioning control and support for "Touch Probe" inputs for high-speed registration. It also features a more advanced internal PLC-like logic capability, allowing it to handle complex motion tasks that would otherwise require an external motion controller.

How is the STO function wired on this specific model?

The STO function is typically accessed via the safety terminals (e.g., X1 cross-connector). It requires a dual-channel 24 VDC signal from a safety relay or safety PLC. When the signal is removed, the drive's power stage is hardware-disabled, preventing any motor torque generation.

Does this drive support encoder feedback for closed-loop control?

Yes. While the base unit handles sensorless vector control, the 8400 HighLine series is designed to accept various feedback modules (incremental, SinCos, or absolute encoders) through its modular expansion slots to achieve high-precision positioning and speed stability.

Engineering & Installation Guide

• Safe Torque Off (STO) Commissioning: When integrating the E84AVHCE1524SB0 into a safety circuit, ensure that the dual-channel wiring is tested for cross-faults. A mismatch between the two safety channels will trigger a drive lock-out to prevent unsafe operation. Always document the safety response time as part of the machine's technical file.

• Thermal Management and Spacing: The HighLine series generates heat proportional to its processing load. Maintain a minimum vertical clearance of 100 mm. For side-by-side installation, a 10 mm gap is recommended. Ensure the cabinet's internal temperature does not exceed 45 Celsius to avoid automatic derating of the 1.5 kW output power.

• Shielding and Signal Integrity: For high-speed positioning applications, use double-shielded cables for encoder feedback and separate them from the motor power cables. Use the integrated EMC shield sheets provided with the 8400 series to ground the motor cable shield over a large surface area directly at the inverter.
