Lenze EMF2113IB 8200 Vector Interbus Communication Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EMF2113IB is an Interbus communication module belonging to the 2100 Series Function Modules designed for host drives including Lenze 8200 Vector frequency inverters and Lenze 9300 series drive controllers. Built for distributed drive automation in automotive manufacturing, packaging machinery, textile production, and material handling systems, the unit plugs directly into the dedicated function slot on the inverter chassis. Power for the module is drawn directly from the host drive internal 5 V DC supply rail at a rated current of 170 mA, eliminating the need for external power wiring while maintaining a compact form factor.
For system integration, the EMF2113IB features dual 9-pin Sub-D connectors utilizing RS-422 differential signaling, providing a male connector for Remote Bus IN and a female connector for Remote Bus OUT pass-through. The fieldbus module operates as an Interbus slave device compliant with DRIVECOM Profile 21 at a fixed transmission rate of 500 kbit/s, protected by integrated 500 V AC galvanic isolation between the fieldbus network and control electronics. Commissioning a replacement unit requires configuring the station address via the integrated DIP switches and ensuring parameterization matches the application, which can be configured using Lenze Global Drive Control (GDC) software, Phoenix Contact CMD software, or drive keypads. Support from ABC Industrial Parts can assist maintenance teams in verifying configuration and selecting compatible replacement options for legacy drive systems.
Diagnostic information is provided on the module front panel via four dedicated status LEDs: Bus Active (BA), Remote Bus Disable (RD), Cable Check (CC), and Diagnostic Fail (FO). Host drive fault codes such as CE0, CE1, CE2, and CE3 indicate communication timeouts, parameter transfer errors, or module initialization failures during power-up. First-line troubleshooting should include inspecting the physical seating on the inverter header pins, verifying Sub-D cable connections, checking Interbus master status, and confirming DIP switch address alignment. If physical seating and fieldbus wiring are sound but module initialization errors persist, internal board faults cannot be serviced in the field, making replacement or tested exchange units through ABC Industrial Parts the most reliable path to restore production.

Programming and Configuration
Parameterization and fieldbus monitoring of the Lenze EMF2113IB module are managed through Lenze Global Drive Control (GDC) software or Phoenix Contact CMD Interbus configuration software. Keypads mounted directly on host 8200 Vector or 9300 drive controllers also allow access to parameter records and fault history logs.
Hardware address assignment and network configuration are established using the onboard DIP switches on the module. When swapping out a module, setting the DIP switches to match the original unit ensures proper station address recognition by the Interbus master without requiring extensive PLC code modifications. Watchdog timeout parameters, such as C0150 and C0357, control process data monitoring durations to maintain safe system shutdown in the event of telegram interruptions.
Communication and System Integration
The EMF2113IB function module operates as an Interbus remote bus slave according to DRIVECOM Profile 21, supporting real-time process data exchange and acyclic parameter transfer at a transmission speed of 500 kbit/s over RS-422 differential line drivers.
Network connections are made via two 9-pin Sub-D connectors mounted on the front panel. The male Sub-D connector serves as the Remote Bus IN interface for the incoming fieldbus cable, while the female Sub-D connector provides Remote Bus OUT pass-through to downstream devices. High-noise industrial environments are accommodated by 500 V AC galvanic isolation between the network line drivers and the inverter internal logic circuitry.
Diagnostics and Status Indication
Comprehensive real-time status monitoring is provided by a four-LED diagnostic array on the front panel of the module, alongside Interbus master status flags and host drive fault registers.
The LED indicators deliver immediate visual notification of network health. Green BA (Bus Active) confirms active data transfer, green CC (Cable Check) indicates valid physical line connection, yellow RD (Remote Bus Disable) signals that downstream remote bus segments are switched off, and red FO (Fiber Optic / Diagnostic Fail) alerts operators to optic power drops, signal degradation, or diagnostic faults along the bus segment.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| BA | Green - Solid | Bus Active: Interbus communication is active and data transfer is taking place. |
| RD | Yellow - Solid | Remote Bus Disable: Downstream remote bus interface is switched off. |
| CC | Green - Solid | Cable Check: Incoming physical Interbus cable connection is verified ok. |
| FO | Red - Solid | Fiber Optic / Diagnostic Fail: Signal quality issues, optic power drop, or diagnostic fault on the segment. |
Replacement and Spare Part Considerations
Replacing an EMF2113IB communication module requires powering down the host inverter before removing or installing the plug-in board. Maintenance personnel should inspect the header pins on the host drive slot for bends or contamination prior to seating the replacement unit to prevent initialization errors.
Before bringing a spare module online, verify that the DIP switch address settings match the replaced unit exactly. Additionally, check that process data watchdog parameters on the host drive (C0150 / C0357) match application requirements to prevent nuisance communication timeouts during master PLC startup.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| CE0 | Communication Error - Function Module | Communication failure or watchdog timeout between the host inverter and the fieldbus module, or interruption of Interbus network communication. | Loose connection between module and inverter header, broken Interbus signal cable, Interbus master stopped, incorrect station address, or defective communication module. | Check module mechanical seating; verify Sub-D cable connectors; verify Interbus master status; check DIP switch address settings. If connection is solid and fault persists, replace EMF2113IB module. |
| CE1 | Process Data Monitoring Time Exceeded | The configured timeout duration for receiving process data over the Interbus network has elapsed. | Interbus master in STOP state, bus cabling interrupted, severe electromagnetic interference. | Check master PLC state; inspect fieldbus cabling and shielding; verify process data watchdog parameter (C0150 / C0357). |
| CE2 | Parameter Data Channel Time Exceeded | Timeout occurred during acyclic parameter transfer via Interbus PCP channel. | High bus utilization, parameter request timeout, invalid parameter index request. | Verify parameter index and sub-index in PLC program; re-try transmission. |
| CE3 | Internal Module Initialization Error | The inverter failed to establish communication with the function module during power-up initialization. | Module not correctly plugged into slot, bent interface pins, internal hardware failure on function module. | Power down inverter, remove and inspect header pins, re-seat module securely. If issue recurs, internal board error requires unit replacement. |
