Lenze E94AYCER 9400-Series Ethernet Extension Module

Product Overview

The Lenze E94AYCER (E94AYCER) is a specialized Ethernet communication extension module designed to expand the connectivity of the 9400-series servo drive family. By integrating this module, system integrators can transition from traditional fieldbus architectures to high-speed Ethernet-based networks, enabling real-time data exchange, remote diagnostic capabilities, and seamless synchronization within complex multi-axis motion control systems. Its design prioritizes ease of integration, allowing for plug-and-play functionality that minimizes downtime during system upgrades or the deployment of new automation nodes.

Technical Configuration

The E94AYCER serves as the communication gateway for the 9400-series, translating drive-internal parameters into standardized Ethernet protocol packets.

• Communication Interface: Provides high-speed Ethernet connectivity, supporting the high-bandwidth requirements of modern industrial networks.
• System Integration: Built specifically for the 9400-series platform, the module mounts directly to the drive, maintaining a clean and compact cabinet footprint.
• Protocol Support: Facilitates integration with standard automation controllers (PLCs) and HMI interfaces, enabling centralized control of drive parameters, status monitoring, and motion profile management.
• Diagnostic Utility: Enables remote access to the drive's internal diagnostic registers, allowing maintenance personnel to troubleshoot performance issues or perform firmware updates via a standard network connection.

Technical Specifications

Frequently Asked Questions

Is the E94AYCER compatible with all 9400-series servo drives?

Yes, the E94AYCER is designed for the 9400-series architecture. However, always ensure your drive's firmware is compatible with the latest version of the Ethernet communication module to avoid connection errors or protocol mismatch.

Does this module require specific cabling for installation?

You should use high-quality, shielded Ethernet (RJ45) cabling (typically Category 5e or 6) designed for industrial environments to prevent signal attenuation or packet loss due to electromagnetic interference (EMI) near motor cables.

Can this module be used for real-time motion control (e.g., EtherCAT)?

The E94AYCER is an Ethernet extension module. While it handles standard Ethernet connectivity, verify the specific version of the module against your required protocol (e.g., Profinet, EtherNet/IP, or EtherCAT) as these are often protocol-specific variants.

Engineering Integration and Operational Protocols

• Shielding and Routing: When installing the module, ensure Ethernet cables are routed in separate cable trays away from high-power motor leads or AC power lines. Inductive interference from high-power cables can degrade network performance and lead to intermittent drive communication timeouts.
• Installation Steps: Power down the servo drive entirely before attempting to install or remove the communication module. Align the module’s pins with the drive’s communication slot and press firmly until the locking mechanism engages. Ensure the module is seated squarely to prevent pin damage.
• Network Addressing: Once installed, assign a unique IP address to the module within your automation network. Using a static IP address is recommended to prevent addressing conflicts that could arise if a DHCP server dynamically reassigns addresses.
• Commissioning: Use the Lenze configuration software to define the module's role within the network. Perform a communication test between the PLC and the drive to confirm that heartbeat signals and process data are exchanging correctly before enabling the servo motor for full-load operation.
