Product Overview

The E94ASHE0474 (E94ASHE0474) is a high-capacity, single-axis servo drive from the Lenze 9400 HighLine series, specifically engineered for precision-heavy industrial applications. Delivering a rated power of 22.0 kW (30 HP), this drive is designed for high-dynamic motion control in complex systems such as large-scale packaging lines, material processing plants, and synchronized multi-axis robotics. Operating on a versatile three-phase 180 V to 550 V mains connection, the E94ASHE0474 provides exceptional torque stability and speed accuracy. As an active product within the Lenze "L-force" portfolio, it offers a modular architecture that supports advanced functional safety, diverse fieldbus communication, and integrated motion control intelligence. Weighing 26.50 kg and built to German manufacturing standards, this drive ensures maximum uptime and operational efficiency in the most demanding B2B electrical environments.

Technical Configuration

The E94ASHE0474 features a sophisticated "HighLine" firmware set that enables complex motion functions directly within the drive, including electronic camming, positioning control, and synchronized speed control. The hardware supports a modular expansion system for plug-in modules such as PROFINET, EtherCAT, and Safety modules (up to SIL 3/PL e). It utilizes high-efficiency power electronics with integrated DC bus connections for energy-sharing in multi-drive lineups. The drive includes a dedicated slot for the E94AYM series memory module, allowing for "Plug & Play" commissioning and rapid device replacement. Its robust design features comprehensive thermal management and high-frequency switching to ensure quiet, cool, and reliable operation under continuous load cycles.

Technical FAQs

Does the E94ASHE0474 support functional safety out of the box?

The 9400 HighLine series is modular. While the drive supports advanced safety, the specific safety functions (like STO, SS1, or SLS) require the installation of a plug-in safety module (e.g., E94AYAS or E94AYAE) into the dedicated safety slot.

Can this drive be used with a 480 V North American grid?

Yes. The E94ASHE0474 is rated for a wide input range up to 550 V. For a 480 V supply, the drive will operate efficiently, though it is critical to ensure that the motor parameters are correctly scaled in the Lenze "Engineer" software for the specific line voltage.

What is the purpose of the integrated DC bus connection?

The DC bus terminals (+UG and -UG) allow the E94ASHE0474 to be connected to other drives in a common DC bus configuration. This allows regenerative energy from a braking motor to be used by another drive in the system, significantly reducing overall energy consumption and heat dissipation.

Engineering & Installation Guide

• Lifting and Mounting: Due to its 26.50 kg weight, use appropriate mechanical assistance or a two-person lift when mounting the unit into the control cabinet. The drive must be mounted vertically on a solid, conductive mounting plate to ensure proper mechanical support and EMC grounding.

• Heat Dissipation: A 22.0 kW drive generates significant thermal energy. Maintain a minimum vertical clearance of 150 mm above and below the unit. Ensure the cabinet has forced-air ventilation capable of handling the drive's total power loss (refer to the technical manual for specific Watt dissipation values at full load).

• EMC and Motor Cables: For high-power servo applications, use only high-flex, double-shielded motor cables. The shield must be clamped 360 degrees at the drive's EMC plate. To prevent interference with sensitive control signals, maintain at least 200 mm of separation between motor cables and parallel signal/communication lines.
