E82EV251-2C LENZE

E82EV251-2C LENZE communication module

Product  Description：

Lenze communication modules are high-performance industrial networking components designed to extend the connectivity of Lenze frequency inverters, servo drives, and controllers (such as the i500, i900, and 8400 series). These modules act as dedicated network interfaces, enabling drive systems to integrate seamlessly into centralized automation architectures. By converting internal drive parameters and control words into standard industrial fieldbus protocols, they facilitate real-time motion control, precise speed regulation, and comprehensive diagnostics from a central PLC.

Product Parameters

The technical baseline of a Lenze communication module is characterized by its high-speed data throughput, protocol compliance, and direct drive integration:

• Supported Protocols: Tailored variants support major global networks including EtherCAT, PROFINET, EtherNet/IP, CANopen, Modbus TCP, and PROFIBUS DP.

• Data Transmission Rate: High-speed industrial Ethernet variants operate at 100 Mbps with full-duplex support, while serial fieldbus variants support protocol-specific baud rates up to 12 Mbps.

• Synchronization and Cycle Time: Optimized for high-speed motion control, capable of handling network cycle times down to the sub-millisecond range with minimal jitter.

• Interface Connections: Equipped with standard industrial ports, typically utilizing dual RJ45 ports with integrated switches for Ethernet daisy-chaining, or specialized Sub-D and terminal connectors for serial networks.

• Power Supply: Draws power directly from the host inverter or drive backplane slot, eliminating the need for an external dedicated power source.

• Status Monitoring: Features integrated logic for network status mapping, transmitting internal drive faults, communication timeouts, and bus errors directly to the master controller.

Product Advantages

Lenze communication modules provide significant engineering and operational benefits for modular machine designs:

• Plug-and-Play Pluggability: Designed for modular insertion, these modules can be easily clipped into the drive's expansion slot, allowing standard inverters to be adapted to different networks at the last minute.

• Integrated Network Routing: Modules featuring dual Ethernet ports include built-in line topology support, reducing external switch requirements and simplifying control cabinet wiring.

• Real-Time Parameter Access: Provides unrestricted access to all internal drive parameters, enabling dynamic adjustment of acceleration ramps, torque limits, and position profiles on the fly.

• High Electromagnetic Immunity: Engineered to withstand the severe electrical noise generated by adjacent high-voltage motor cables and switching transistors within industrial enclosures.

• Simplified Engineering Integration: Fully supported by Lenze engineering software tools like EASY Product Finder and PLC Designer, featuring pre-configured electronic data sheets (GSDML, ESI, EDS files) for fast commissioning.

Product Applications

These modules are widely used across automated industries requiring coordinated motion and distributed drive control:

• Material Handling and Conveyors: Linking multiple decentralized inverters along extensive logistics networks to synchronize conveyor speeds and sorting gates.

• Packaging Machinery: Providing the high-speed EtherCAT or PROFINET backbone required to coordinate multi-axis servo drives in wrapping, filling, and cartoning machines.

• Automotive Assembly Lines: Integrating variable frequency drives into factory-wide PROFINET or EtherNet/IP networks for precise control of lifting stations and assembly fixtures.

• Intralogistics and Automated Warehouses: Powering the communication interface for stacker cranes, shuttle systems, and automated guided vehicles (AGVs).

• Textile and Printing Equipment: Synchronizing multiple web-handling drives to maintain precise material tension and avoid product deformation during continuous processing.

Important Precautions

To avoid communication drops and prevent damage to the drive system, the following operational instructions must be adhered to:

• Power-Off Installation: Never insert, remove, or modify a communication module while the host inverter or servo drive is powered on. Doing so can cause permanent damage to the sensitive logic interface pins.

• Address and Switch Configuration: For modules utilizing physical DIP switches for station addressing or baud rate selection, ensure these are configured correctly before powering on the system, as changes made during operation may not take effect.

• Shielding and Grounding: Use only high-quality, shielded industrial twisted-pair cables. Ensure that the cable shield makes secure physical contact with the connector housing to prevent ambient electromagnetic noise from disrupting data frames.

• Network Topology Compliance: Observe standard segment length restrictions (such as 100 meters for Ethernet copper) and install termination resistors at both ends of a serial network line (like PROFIBUS or CANopen) to prevent signal reflection.

• Timeout Parameter Setting: Always configure the drive's communication timeout parameters (watchdog timer). This ensures that if network communication is lost, the drive will safely decelerate or trip rather than continuing to run blindly on its last received command.
