E94ASHE0174 Lenze 9400 HighLine Servo Drive

Product Overview

The E94ASHE0174 (E94ASHE0174) is a high-performance, three-phase single drive from the Lenze 9400 HighLine series, engineered for sophisticated motion control in automated production environments. Delivering a rated power of 7.5 kW, this servo drive is designed to handle demanding dynamic tasks such as electronic gearing, cam technology, and high-speed positioning. Whether utilized in packaging machinery, textile production, or material handling, the E94ASHE0174 excels in reducing cycle times and increasing machine precision. Its compact design (24.00 x 14.00 x 12.50 cm) allows for high power density in space-constrained control cabinets, while its robust German engineering ensures maximum operational uptime and a long service life in harsh industrial settings.

Technical Configuration & System Integration

The Lenze E94ASHE0174 features a versatile power stage capable of operating within a wide voltage range of 180 to 550 V. For systems up to 55 kW, it maintains a nominal voltage of 400 V, providing stable torque across the entire speed range. The HighLine architecture is modular, allowing for the easy addition of communication and safety modules. It supports advanced networking protocols including Profinet, EtherCAT, Powerlink, and Profibus, enabling seamless integration into multi-axis systems and synchronized motion loops. The drive's internal intelligence handles complex motion profiles locally, significantly reducing the computational load on the central PLC.

Technical FAQs

Does the E94ASHE0174 support integrated safety functions?

Yes, the 9400-series supports modular safety technology. Depending on the plugged-in safety module, the E94ASHE0174 can perform functions such as STO (Safe Torque Off), SS1, and others, meeting SIL 3/PL e requirements.

How is the drive programmed and commissioned?

Commissioning is typically handled through the Lenze Engineer software suite. This allows for easy parameterization, configuration of the motion control blocks, and real-time monitoring of drive performance.

Can this drive be used in a multi-axis DC bus configuration?

While the E94ASHE0174 is a single-axis drive, the 9400-series is designed to share a common DC bus in multi-axis setups to enable energy exchange between motoring and braking axes, improving overall system energy efficiency.

Engineering & Installation Guide

• Heat Dissipation: Due to the 7.5 kW power rating, ensure a minimum vertical clearance of 100 mm above and below the drive. The E94ASHE0174 utilizes active fan cooling; verify that the cabinet's ambient temperature remains below 45 Celsius for continuous full-load operation.

• EMC Compliance: Use shielded motor cables and ensure the shield is connected over a large area to the mounting plate using EMC clips. This is critical for preventing high-frequency interference with nearby communication modules or sensors.

• Braking Resistor: For applications involving rapid deceleration of high-inertia loads, install an external braking resistor to dissipate regenerative energy. Check the DC bus voltage thresholds in the Lenze Engineer software to properly size the resistor.

Engineering Advantages

The E94ASHE0174 stands out for its "Plug-and-Play" modularity. The drive's memory module (MM220) stores all parameters, allowing for rapid device replacement without a PC—simply swap the memory module into a new drive to restore operation. Furthermore, the 9400-series high-resolution feedback interface supports a wide variety of encoders (Resolver, SinCos, TTL), ensuring that the drive can be paired with almost any high-performance synchronous or asynchronous motor.
