Lenze EMF2175IB DeviceNet Communication Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EMF2175IB is a DeviceNet fieldbus communication module in the Lenze System Bus / Fieldbus Communication Modules family. Designed to integrate host drives into centralized automation architectures, this function module connects directly into the internal Function Module Interface (FIF) slot of Lenze 8200 vector frequency inverters and Lenze 9300 servo drives. Physical network cabling connects via a 5-pin pluggable screw terminal block, and the unit operates on a 24 V DC supply voltage to establish a reliable ODVA-compliant DeviceNet slave interface for high-level controllers.
Commissioning a replacement EMF2175IB module requires matching physical fieldbus settings to the host control system. Network MAC ID addresses from 0 to 63 and transmission speeds of 125 kbit/s, 250 kbit/s, or 500 kbit/s can be set directly via onboard hardware DIP switches. Alternatively, parameter adjustment can be performed through Lenze Global Drive Control (GDC) software or an EMZ2101 / XT Keypad terminal connected to the drive. ABC Industrial Parts can support maintenance teams with parameter verification to ensure spare units match existing drive configurations before deployment.
System status monitoring and local network diagnostics are provided by front-panel dual-color LEDs for Module Status (MS) and Network Status (NS), as well as drive parameters C0150 and C0151. Network faults on the physical layer generate explicit drive codes such as CE0 for fieldbus time-outs and CE1 for CAN bus-off conditions, which can be resolved by checking cable connections, shielding, and line termination. Internal communication failures between the drive and card trigger fault code CE3; if re-seating the unit in the FIF slot does not clear the condition, board-level faults are present, making unit replacement or repair through ABC Industrial Parts the standard route back to production.

Programming and Configuration
The EMF2175IB communication module provides flexible options for setting up node addresses and communication parameters on DeviceNet networks. Manual configuration is achieved using onboard DIP switches, allowing technicians to define the DeviceNet MAC ID address within a range of 0 to 63 and set standard bus speeds of 125 kbit/s, 250 kbit/s, or 500 kbit/s directly on the hardware.
For software-based configuration, the module fully integrates with Lenze Global Drive Control (GDC) software and the Lenze EMZ2101 / XT Keypad terminal. Parameters such as code C0150 and C0151 allow access to network parameters, diagnostic data, and node settings directly within Lenze 8200 vector and 9300 servo drive systems.
Communication and System Integration
Operating as an ODVA-certified DeviceNet slave, the EMF2175IB enables centralized parameterization, real-time motion control, and diagnostic monitoring from master PLC controllers. The module mounts directly into the host drive's Function Module Interface (FIF) slot, creating an internal bridge between drive intelligence and the fieldbus network.
Physical connection to the DeviceNet trunk line is made using a 5-pin pluggable screw terminal block. Network stability and noise immunity across transmission rates up to 500 kbit/s require standard 120-ohm termination resistors applied at the physical ends of the line along with proper shield grounding.
Diagnostics and Status Indication
The front panel of the EMF2175IB features two dual-color LED indicators for immediate visual status verification. The Module Status (MS) LED indicates internal hardware readiness, while the Network Status (NS) LED displays the operational state and connection health of the DeviceNet link.
Detailed diagnostic tracking is accessible via host drive code C0150/C0151 parameters, the GDC software diagnostic view, and the optional XT Keypad terminal, allowing maintenance personnel to evaluate physical layer issues or master-slave handshake failures.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Module Status (MS) | Green/Red - Solid / Flashing / Off | Indicates internal module status and operational readiness |
| Network Status (NS) | Green/Red - Solid / Flashing / Off | Indicates DeviceNet communication state and connection health |
Replacement and Spare Part Considerations
Replacing a damaged EMF2175IB card involves inserting the spare module directly into the Function Module Interface (FIF) slot of a Lenze 8200 vector frequency inverter or Lenze 9300 servo drive. Power to the host drive must be disconnected prior to inserting or removing the communication board.
Before restoring power and putting the system back into service, verify that the DIP switch settings for MAC ID node address (0 to 63) and baud rate (125, 250, or 500 kbit/s) match the original unit. Once powered up, check parameter codes C0150/C0151 or use Global Drive Control software to confirm communication with the fieldbus master is fully restored.
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 / Fieldbus Time-out | Communication interruption between DeviceNet master and EMF2175IB module or module time-out reached. | Bus cable disconnected, DeviceNet master stopped, incorrect baud rate, loose wiring. | Check DeviceNet cabling, termination resistors, network master status, and baud rate setting. |
| CE1 | Communication Error 1 / Bus Off | DeviceNet controller went Bus-Off due to excessive transmission errors on the CAN physical layer. | Faulty bus line, incorrect shielding, missing termination resistors, noise interference. | Check network wiring, shield grounding, 120-ohm termination resistors at physical ends of the line. |
| CE3 | INTERNAL COMMUNICATION ERROR | Communication failure between host drive controller and the EMF2175IB function module. | Module not seated properly in host drive slot, hardware revision incompatibility, or defective internal communication board. | Turn off power, re-seat the module in the FIF slot. If error persists, replace the EMF2175IB module or check host drive. Hardware fault requires unit replacement. |
Frequently Asked Questions
Which Lenze drives are compatible with the EMF2175IB communication module?
The EMF2175IB module connects directly into the Function Module Interface (FIF) slot of Lenze 8200 vector frequency inverters and Lenze 9300 servo drives.

Node addresses from 0 to 63 and baud rates of 125, 250, or 500 kbit/s can be configured manually using hardware DIP switches on the module, or digitally via Lenze Global Drive Control (GDC) software or an XT Keypad.
What physical connector is used for the fieldbus line on the EMF2175IB?
The module uses a 5-pin pluggable screw terminal block to connect directly to the DeviceNet fieldbus line.
What causes drive fault codes CE0 and CE1 on Lenze drives using this module?
Fault code CE0 indicates a DeviceNet fieldbus time-out or master connection interruption, while CE1 indicates a CAN bus-off state caused by excessive physical layer transmission errors.
What action is recommended if the drive displays fault code CE3?
Fault code CE3 signifies an internal communication error between the host drive and the EMF2175IB module. Turn off drive power and re-seat the module in the FIF slot. If the error persists, internal hardware damage is present and the module or drive requires replacement.
