E94ASHE0044 Lenze 9400-series High-Performance Servo Drive

Product Overview

The E94ASHE0044 (E94ASHE0044) is a precision-engineered single-axis servo module within the renowned Lenze 9400 HighLine series, designed to orchestrate complex motion control tasks with superior dynamic response. This 1.5 kW rated power unit excels in demanding industrial environments such as high-speed packaging lines, automotive assembly cells, and precision textile manufacturing. By integrating this drive into your automation architecture, you ensure sub-millisecond control loops and robust electromagnetic compatibility, which are critical for reducing unplanned downtime in continuous process industries like pulp and paper or chemical processing. Its modular design allows for seamless integration of safety functions and fieldbus communication, providing a future-proof solution for OEMs and system integrators focused on maximizing OEE (Overall Equipment Effectiveness).

Technical Configuration

The Lenze 9400-series architecture is built on a modular platform that separates the power stage from the control unit, allowing for highly specific application tailoring. The E94ASHE0044 features a sophisticated internal DC bus system that enables energy balancing in multi-axis configurations, significantly improving overall energy efficiency. It supports a wide voltage input range of 180 to 550 VAC, ensuring stable performance despite fluctuating grid conditions often found in heavy industrial zones. The drive is equipped with standard interfaces for resolver and encoder feedback, and can be expanded via plug-in modules for EtherCAT, PROFINET, or Ethernet/IP communication. This hardware configuration is optimized for "Single Drive" installations where space-saving and high power density are paramount.

Technical Specifications

Technical FAQs

How does the E94ASHE0044 handle safety-related applications?

The 9400-series supports modular safety technology. Depending on the plugged-in functional safety module, it can achieve Drive-based safety functions such as STO (Safe Torque Off), SS1 (Safe Stop 1), and SLS (Safely Limited Speed) up to SIL 3/PLe standards.

Can this drive be used in multi-axis DC bus sharing configurations?

Yes, the E94ASHE0044 is designed to support DC bus connection. This allows for energy exchange between motoring and regenerating drives, which reduces heat dissipation and saves energy costs in systems with frequent braking cycles.

What is the recommended cooling clearance for this specific frame size?

To ensure optimal thermal management, a minimum vertical clearance of 100 mm above and below the unit is required. Horizontal mounting requires no side clearance if the ambient temperature remains within the rated specification of 45 deg C.

Engineering & Installation Guide

For reliable long-term operation of the E94ASHE0044, strict adherence to electromagnetic compatibility (EMC) protocols is mandatory. All motor cables must be 360-degree shielded at both the drive and motor ends using conductive metal clamps; avoid using "pigtail" shield terminations as they introduce high-frequency impedance. When installing in high-vibration environments, ensure the mounting backplane is a zinc-coated steel plate to provide both structural rigidity and a low-impedance ground path. For thermal management, if the internal cabinet temperature exceeds 45 deg C, apply a current derating factor of 2.5% per deg C up to a maximum of 55 deg C. Ensure the power terminals are tightened to the specified torque of 0.5 to 0.6 Nm to prevent resistive heating at the contact points.
