Module de communication Ethernet POWERLINK Lenze E94AYCEP série 9400

Product Overview

The E94AYCEP (E94AY CEP) is a high-performance communication expansion module designed for the Lenze 9400-series HighLine servo drives. This module provides a dedicated Ethernet POWERLINK interface, enabling the drive to function as either a Managing Node (MN) or a Controlled Node (CN) within a real-time industrial Ethernet network. Engineered in Germany, the E94AYCEP is essential for high-speed, synchronized multi-axis motion control applications where microsecond-level jitter and deterministic data exchange are required. Its compact, pluggable design allows for effortless integration into the drive's communication slot, enhancing system scalability and monitoring capabilities in demanding automation environments.

Technical Configuration

The E94AYCEP module leverages the POWERLINK protocol to facilitate isochronous data transfer, making it ideal for CNC machinery, high-speed robotic pick-and-place systems, and complex printing presses. The module supports a standard RJ45 interface and is designed for the "Active" phase of the product lifecycle, ensuring long-term compatibility and support. As a plug-and-play component for the 9400-series, it utilizes the internal bus of the servo drive to map process data objects (PDO) directly into the drive’s control logic. This architecture minimizes processing overhead and ensures that motion commands are executed with maximum precision relative to the master controller.

Technical Specifications

Technical FAQs

What is the difference between MN and CN modes for the E94AYCEP?

The module is capable of acting as a Managing Node (MN), which coordinates the network timing and polls other devices, or more commonly as a Controlled Node (CN), which responds to the master controller. This flexibility allows the 9400-series drive to adapt to various network topologies.

Does this module require external power?

No. The E94AYCEP draws its operating power directly from the internal bus of the Lenze 9400 servo drive once it is seated in the communication slot, simplifying wiring and reducing cabinet complexity.

Can I use standard Ethernet cables with this POWERLINK module?

While POWERLINK uses the Ethernet physical layer, it is highly recommended to use industrial-grade shielded CAT5e (or higher) cables. This ensures the real-time performance is not degraded by electromagnetic interference (EMI) typical in industrial motor environments.

Engineering & Installation Guide

• Slot Installation: Before installing the E94AYCEP, ensure the 9400-series drive is completely powered down. Disconnect the 24V DC control supply and the main AC power. Insert the module into the designated communication slot until the locking mechanism clicks into place.

• Node Addressing: The POWERLINK node ID is typically set via the drive's onboard DIP switches or through the "L-force Engineer" software. Ensure that each node on the network has a unique ID (range 1–239 for CN) to avoid communication collisions.

• Network Topology: Ethernet POWERLINK supports various topologies, including line, star, and tree. For optimal performance in motion control, a line topology (daisy-chaining) is often used; however, ensure that the total network cycle time is configured in the master controller to accommodate the number of nodes present.
