Lenze E94ASHE0324 9400-Series Servo Drive

Product Overview

The Lenze E94ASHE0324 (E94ASHE0324) is a high-performance single-axis servo drive from the 9400-Series, engineered for precise motion control in high-complexity industrial automation environments. With a rated power output of 15.0 kW, this drive is designed to handle demanding motion profiles—such as high-speed robotic manipulation, multi-axis synchronization in packaging, and dynamic metal forming—where accuracy and repeatability are non-negotiable. Its architecture allows for seamless integration into sophisticated control systems, significantly enhancing machine throughput and reliability while reducing mechanical wear through optimized acceleration and deceleration curves.

Technical Configuration

The 9400-Series is built upon a highly modular concept, providing a scalable foundation for both simple and intricate motion control tasks.

• Advanced Motion Control: The E94ASHE0324 supports sophisticated positioning and synchronization logic, allowing it to execute complex motion profiles with high-speed response times.
• Communication Versatility: Through optional plug-in modules, the drive supports a wide array of industrial protocols including Ethernet, Powerlink, Profinet, and Profibus, ensuring robust interoperability with modern PLC architectures.
• Integrated Safety: The drive design accommodates advanced safety functions such as Safe Torque Off (STO), facilitating compliance with modern machine safety directives without requiring extensive external safety hardware.
• Operational Stability: Designed to operate across a broad voltage range (180 - 550 V), the power stage maintains output stability even in factory environments with fluctuating grid voltage.

Technical Specifications

Frequently Asked Questions

Is the E94ASHE0324 suitable for high-dynamic multi-axis synchronization?

Yes, the 9400-Series is specifically designed for high-dynamic applications. The drive’s high-speed internal processing loops ensure that multiple axes remain perfectly synchronized, which is essential for coordinated motion in high-speed machinery.

Can this drive be retrofitted into existing 9400-Series cabinets?

Yes, the drive follows the standardized 9400-Series footprint, making it a viable candidate for upgrades or replacements in existing installations. Ensure your cabinet ventilation is sufficient for the heat dissipation requirements of a 15.0 kW unit.

Does this drive require specific software for commissioning?

Yes, commissioning and parameterization are performed using Lenze’s dedicated engineering software suite, which facilitates the mapping of motion profiles, communication settings, and safety configurations.

Engineering Integration and Operational Safety

• Cooling Requirements: Given the 15.0 kW power rating and the 29.20 kg weight, the drive must be mounted securely on a reinforced backplate. Ensure at least 150 mm of vertical clearance above and below the unit to allow for unimpeded heat dissipation, as internal power components are sensitive to ambient temperature derating.
• Cable Shielding: To maintain the precision of the motion loops, use double-shielded, low-capacitance cables for all encoder feedback signals. Terminate the shield using a 360-degree conductive clamp at the drive input point to effectively suppress electromagnetic noise.
• DC Bus Configuration: For systems requiring energy recovery (e.g., high-inertia deceleration), the 9400-Series allows for DC bus sharing. When connecting multiple drives, ensure the common DC bus is properly protected with high-speed semiconductor fuses.
• Safety Commissioning: Before putting the system into full operation, conduct a comprehensive test of the STO (Safe Torque Off) function to confirm that the drive correctly isolates the motor output when the safety circuit is triggered.
