Lenze 00472566 EMF2174IB – INTERBUS Communication Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00472566 EMF2174IB is an INTERBUS fieldbus communication option module belonging to the Global Drive Accessories range. Designed as a plug-in option card, this unit integrates host drive controllers—such as the Lenze 8200 vector frequency inverter series and 9300 series servo controllers—into central INTERBUS industrial networks as a remote bus slave node. The module mounts directly into the drive's multi-pin Automation Interface (FIF) slot and draws its required 5 V DC operating voltage directly from the host drive, eliminating the need for external power supply wiring.
Physical network integration is accomplished via two standard 9-pin D-Sub RS-422 ports: a female connector for the incoming remote bus and a male connector for the outgoing remote bus, facilitating clean daisy-chain topologies at transmission speeds up to 500 kbit/s. Commissioning a replacement unit requires configuring local hardware DIP switches for bus addressing and aligning process data mapping—up to 6 process data words—with drive parameters such as C0005 and C0006 using Lenze Global Drive Control (GDC) software, an XT or EMZ2101 keypad, or Phoenix Contact CMD configuration tools. Because a spare module relies on host parameter matching and correct DIP switch positioning to establish proper communication with the INTERBUS master, ABC Industrial Parts can assist in verifying hardware parameters and commissioning spares efficiently.
Real-time operational status and network health are displayed on the front panel via four diagnostic LEDs: Remote Bus Disabled (RD), Bus Active (BA), Cable Check (CC), and Transmit/Receive Fail (TR). When communication issues arise, the host controller reports error codes such as CE0 for module interface faults, CE1 for bus cable or master transmission timeouts, CE2 for process data mapping mismatches, and CE3 for internal hardware failures. Initial field troubleshooting should focus on verifying physical module seating in the FIF slot, checking bus cable connections, confirming termination, and reviewing DIP switch settings. Internal component failures or board-level faults flagged under error CE3 cannot be serviced in the field, making a tested replacement or professional repair through ABC Industrial Parts the quickest solution to resume production.

Programming and Configuration
Configuring the Lenze 00472566 EMF2174IB module requires a combination of hardware switch adjustments on the option card and parameter settings within the host drive controller. Network address identification on the INTERBUS network is established locally using hardware DIP switches located on the module itself. These switch positions must be set prior to powering up the system to ensure the INTERBUS master controller correctly recognizes the slave node during bus initialization.
Data exchange configuration between the EMF2174IB and the host drive relies on parameter settings stored within the drive memory. Technicians can adjust parameters C0005 and C0006 to define the allocation and mapping of up to 6 process data words (PCD) transferred across the network. These parameters can be modified using an attached XT or EMZ2101 control keypad, or via a PC running Lenze Global Drive Control (GDC) software. Additionally, system integrators using Phoenix Contact INTERBUS master controllers can configure network-wide mapping using standard CMD tools.
Communication and System Integration
The EMF2174IB module operates as an INTERBUS remote bus slave node designed for seamless integration into central automation networks. The module supports transmission speeds up to 500 kbit/s over RS-422 differential transmission lines. Signal connections are made using standard 9-pin D-Sub connectors on the front face of the module, featuring a female D-Sub connector for the incoming remote bus line and a male D-Sub connector for continuing the remote bus loop to down-line nodes.
Interfacing with the host drive is handled via the internal multi-pin Automation Interface (FIF) slot, which establishes high-speed internal communications and delivers a regulated 5 V DC power supply directly to the module board. The module transfers up to 6 process data words cyclically, allowing central controllers to deliver real-time speed commands, operating modes, and control words while simultaneously receiving feedback parameters, operational status, and drive diagnostic data.
Diagnostics and Status Indication
The Lenze EMF2174IB communication card features four front-panel LED indicators that provide instant visual diagnostics regarding network health and interface states. The Cable Check (CC) LED illuminates solid to indicate a valid physical connection on the incoming remote bus, while the Bus Active (BA) LED signals active INTERBUS data transmission. The Remote Bus Disabled (RD) LED illuminates when the outgoing remote bus segment is disabled or disconnected. The Transmit/Receive Fail (TR) LED indicates controller initialization or active error conditions.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| RD (Remote Bus Disabled) | Solid | ON: Outgoing remote bus interface is switched off or disconnected. |
| BA (Bus Active) | Solid | ON: INTERBUS bus communication is active and transmitting data. |
| CC (Cable Check) | Solid | ON: Incoming remote bus connection is physically established and OK. |
| TR (Transmit/Receive / Fail) | Solid / Flashing | ON / Flashing: Interbus controller initialization or error state. |
Replacement and Spare Part Considerations
When replacing a faulty Lenze 00472566 EMF2174IB module, technicians must ensure that the drive system is completely powered down before removing or inserting the option card into the Automation Interface (FIF) slot. Care must be taken to seat the multi-pin interface connector squarely to prevent pin damage or intermittent communication errors such as fault code CE0.
Before putting a replacement unit into service, verify that the local DIP switch positions on the spare module match the hardware address settings of the original board. Additionally, because process data mapping relies on parameter records held inside the drive unit, ensure parameters C0005 and C0006 are configured consistently with the INTERBUS master setup. Verifying cable integrity, baud rate settings, and bus termination prior to restarting the network will prevent startup timeouts and bus configuration faults.
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 0 | Communication failure between host drive and option module (Automation Interface). | Module not fully plugged in, defective interface connection, or internal hardware error. | Power down drive, re-seat EMF2174IB module securely. If error persists, replace module. |
| CE1 | Communication Error 1 | Process data monitoring fault / INTERBUS master timeout. | INTERBUS bus cable interrupted, master stopped transmission, baud rate mismatch, or improper bus termination. | Check INTERBUS bus cables, connections, status of INTERBUS master controller, and DIP switch settings. |
| CE2 | Communication Error 2 | Interbus process data fault / invalid task configuration. | Inconsistent mapping of process data words in master configuration or drive parameters. | Verify master program configuration matches drive PCD word assignments in parameter C0005/C0006. |
| CE3 | Communication Error 3 | Interbus option module internal hardware defect. | Internal component failure or memory corrupted on EMF2174IB communication board. | Internal hardware fault — return module for repair or replace unit. |
