Lenze 00457449 E82ZAFLC – LECOM RS232/RS485 Communication Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00457449 E82ZAFLC is a dual serial communication function module engineered for direct integration with Lenze 8200 vector frequency inverters. Designed to expand drive networking capability, this compact function module mounts directly into the built-in Function Interface (FIF) slot of the host inverter and draws its required 5 V DC operating power directly through the interface header, eliminating the need for external power supply wiring.
Featuring integrated physical interfaces for both RS-232 and RS-485 serial standards, the module supports point-to-point connections under the LECOM-A protocol and multi-drop network topologies under the LECOM-B protocol at transmission speeds ranging from 2,400 bit/s to 115,200 bit/s. Point-to-point RS-232 communication enables direct laptop or HMI connection for parameter tuning and diagnostics, while the RS-485 interface permits multiple inverters to be linked to a central programmable logic controller. Because communication parameters such as node address and baud rate are retained within the host drive's non-volatile memory, swapping a damaged unit for a spare from ABC Industrial Parts requires minimal re-commissioning work.
Visual operational feedback is provided via front-panel status LEDs that report power, active data transfer, and communication fault states. System diagnostics can also be monitored directly on the host drive display or through engineering software, where specific LECOM fault codes help pinpoint network timeouts or interface connection issues. If physical inspection and pin seating in the FIF slot do not clear an internal communication fault, replacing the card with a tested unit from ABC Industrial Parts offers a fast path back to operational status.

Programming and Configuration
Parameterization and commissioning of the Lenze 00457449 E82ZAFLC communication module are performed using Lenze Global Drive Control (GDC) or Global Drive Control Easy (GDC Easy) engineering software. Connecting a host PC via the RS-232 serial interface enables real-time parameter configuration, live drive monitoring, and diagnostic evaluation.
All operational settings for the communication module—including the LECOM node address and serial transmission speed—are stored in the non-volatile memory of the host 8200 vector inverter. This design ensures that all bus parameters remain safe in the inverter during hardware replacement, allowing simple module swapping without re-parameterization.
Communication and System Integration
The E82ZAFLC module combines RS-232 (LECOM-A) and RS-485 (LECOM-B) physical interfaces on a single plug-in board. The RS-232 interface provides point-to-point communication suitable for direct PC or HMI connections, while the RS-485 interface supports multi-drop serial networking, connecting multiple frequency inverters to a central PLC over a common bus structure.
Direct installation into the host inverter's Function Interface (FIF) slot establishes both mechanical mounting and electrical power connection without external cabling. Configurable serial transmission speeds from 2,400 bit/s up to 115,200 bit/s allow flexible adaptation to different controller requirements and network distances.
Diagnostics and Status Indication
Front-panel LED indicators provide visual feedback regarding module power and data transfer states. The green Ready/OK LED confirms operating power and active message traffic, while the red Error/ERR LED indicates communication timeouts, frame errors, or internal interface communication failures.
Detailed diagnostic codes can be reviewed using host drive displays, optional keypad modules such as the EMF2102IB or E82ZBC, or the Global Drive Control software status monitor. These tools enable maintenance technicians to identify bus errors, signal corruption, or improper node settings.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready / OK | Green - Solid / Active | Module powered and operational / Active data transmission |
| Error / ERR | Red - Solid / Flashing | Communication timeout, framing error, or internal module communication failure with inverter |
Replacement and Spare Part Considerations
When replacing a failed Lenze 00457449 E82ZAFLC card, always ensure that the 8200 vector inverter is completely powered off prior to removing or inserting the module. Inserting or removing the module while powered can cause electrical damage to the FIF interface contacts.
Because the node address, baud rate, and bus configuration parameters are stored inside the inverter's internal non-volatile memory, a replacement card will automatically operate under the host drive's existing settings once fully seated in the FIF slot. If communication issues occur following module replacement, verify physical seating, pin alignment, and serial cable shielding.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| CE0 | Communication Time-out (LECOM) | Communication failure or time-out on LECOM interface | Cable disconnected, wrong baud rate, host system stopped sending cyclic data, bus interference | Check RS232/RS485 wiring, verify baud rate and node address settings in host and drive, check master cyclic output interval |
| CE1 | Communication Error to Function Module | Internal communication failure between drive control board and LECOM function module (FIF slot) | Module not seated correctly in FIF slot, hardware failure on function module, loose contacts | Power down inverter, remove and re-seat E82ZAFLC module in FIF slot, check for bent pins. If error persists, replace module. |
| CE2 | Communication Error (Automation Interface) | Time-out or bad data packets received by the automation interface | Data sequence error or corruption over serial connection | Check shielding and grounding of RS232/RS485 communication line |
| CE3 | LECOM Buffer Overflow / Frame Error | Data buffer overload or invalid frame structure received via LECOM interface | Incorrect framing parameters (stop bits, parity), baud rate mismatch, excessive polling frequency | Verify serial frame configuration in master controller and reduce request frequency |
Frequently Asked Questions

The module is configured using Lenze Global Drive Control (GDC) or Global Drive Control Easy (GDC Easy) software connected via the RS-232 interface.
Are communication settings lost when swapping an E82ZAFLC module?
No. All communication settings, such as the node address and baud rate, are stored in the host 8200 vector inverter's non-volatile memory, permitting direct hardware replacement without re-configuration.
Which serial interfaces are supported by the E82ZAFLC function module?
The module provides both RS-232 (LECOM-A) for point-to-point connections and RS-485 (LECOM-B) for multi-drop serial bus structures.
What baud rates are supported by this communication module?
The module supports configurable transmission speeds ranging from 2,400 bit/s up to 115,200 bit/s.
What does fault code CE1 indicate on the drive display?
Fault code CE1 indicates an internal communication failure between the drive control board and the FIF slot module, often caused by loose seating, bent pins, or hardware module failure.
