Module de communication INTERBUS Lenze série 8200 EMF2113IB

Product Overview

The EMF2113IB (EMF2113IB) is a high-performance INTERBUS fieldbus interface module designed for the Lenze 8200-series and 8200 motec frequency inverters. This specialized accessory enables the seamless integration of motor drives into INTERBUS network architectures, providing a robust digital link for real-time control and diagnostic data exchange. Supporting switchable transmission rates of 500 kbit/s and 2 Mbit/s, the EMF2113IB ensures high-speed synchronization between the master controller and decentralized drive units. Engineered in Germany, this module is critical for maintaining uptime in large-scale industrial networks, such as those found in automotive assembly lines and complex conveyor systems, where reliable data throughput and reduced wiring complexity are paramount for operational efficiency.

Technical Configuration

The EMF2113IB features a pluggable design that mounts directly into the function slot of the 8200-series inverter. It utilizes a standard 9-pin D-Sub connection for the INTERBUS remote bus, facilitating easy "daisy-chain" wiring. The module supports a variety of data formats and is capable of handling both process data (for rapid speed and torque control) and parameter data (for remote configuration). Integrated diagnostic LEDs provide immediate status updates on bus activity and internal module health, allowing for rapid troubleshooting without specialized external tools. Its hardware is optimized for the high-interference environments typical of motor control cabinets, utilizing potential-free isolation to protect the sensitive communication logic from power-stage transients.

Technical FAQs

How do I select between 500k and 2M baud rates on the EMF2113IB?

The transmission speed is typically selected via hardware DIP switches located on the module or through specific internal parameter settings within the 8200 inverter (refer to the C15xx code range in the manual). Ensure the entire INTERBUS segment is configured for the same speed to avoid network collisions.

Is an external power supply required for this module?

No, the EMF2113IB draws its operating power directly from the frequency inverter's internal supply via the system bus interface. However, the INTERBUS remote bus signals themselves are galvanically isolated to prevent noise propagation.

Can this module be used with the 8200 Motec (motor-mounted) drives?

Yes, the 2113IB is compatible with both the cabinet-mounted 8200 Vector series and the decentralized 8200 Motec units, provided the drive has the appropriate expansion slot for fieldbus modules.

Engineering & Installation Guide

• Bus Termination and Topology: INTERBUS is a ring-structured bus system physically implemented as a point-to-point connection. Ensure that the "Remote Bus Out" from one module connects correctly to the "Remote Bus In" of the next. Termination is handled automatically by the INTERBUS master or specialized connectors; however, always verify the integrity of the return loop to prevent "Bus Open" faults.

• EMC and Shielding: To ensure stable communication at 2 Mbit/s, use only certified INTERBUS cables. The 9-pin D-Sub shell must have a 360-degree contact with the cable shield, and the shield should be grounded to the inverter's PE terminal via the module’s mounting hardware to mitigate the effects of PWM noise from the drive.

• Module Insertion: Only insert or remove the EMF2113IB when the frequency inverter is completely powered down. "Hot-swapping" this module can cause a surge on the internal system bus, potentially corrupting the drive's EEPROM or damaging the communication transceiver on the module.
