Lenze 00426368 E82ZAFC001 LECOM RS232/RS485 Communication Module
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 00426368, model designation E82ZAFC001, is a serial communication function module designed for direct plug-in mounting into Lenze 8200 vector and 8200 motec frequency inverters. Operating within the host inverter's Function Interface (FIF) slot, this module draws internal 5 V DC power directly from the drive backplane. It equips the host drive with serial connectivity options, enabling commissioning, monitoring, and multi-drop networking in industrial environments such as material handling, conveyor systems, packaging machinery, and automotive assembly lines.
Physical connectivity is provided via a 9-pin female Sub-D connector for point-to-point RS-232 links and plug-in screw terminals for 2-wire RS-485 bus connections. Supporting LECOM-A (RS-232) and LECOM-B (RS-485) protocols, the unit allows individual drive setup or multi-drop networking of up to 90 drive nodes on a single serial bus. Commissioning a replacement unit requires no firmware flashing or software downloading directly on the module itself; technicians simply replicate the physical DIP switch positions—which select the station address, baud rate up to 57,600 bit/s, operating mode, and integrated RS-485 line termination—from the original unit onto the spare. ABC Industrial Parts provides tested replacement units to help restore networked drive control quickly.
Real-time status monitoring is provided by onboard LED indicators, including a green PWR/Ready LED for internal power and health, alongside a yellow/red COM LED for active data frame transmission and reception. Diagnostic readouts can also be accessed using Global Drive Control (GDC) software or via an E82ZBC keypad module installed on the host drive. Common communication errors include code CE0, indicating a loss of interface connection at the drive FIF slot, and CE1, indicating a serial LECOM time-out. Initial troubleshooting should confirm that the module is firmly seated in the slot, inspect cable connections, and verify that hardware DIP switch settings match the host controller. If internal board faults cause persistent communications failures, replacing the module is the most effective route back to production, with support available from ABC Industrial Parts.

Programming and Configuration
The Lenze E82ZAFC001 LECOM module utilizes physical hardware switches for core operational parameters, eliminating the need for module-level software flashing or parameter downloads. Station addresses, transmission speeds up to 57.6 kbps, operating modes, and bus line termination are set using circuit board DIP switches prior to inserting the module into the host drive.
For drive-level parameters and commissioning, the module interface supports connection to host software tools including Lenze Global Drive Control (GDC) and GDC Easy. Through the RS-232 or RS-485 physical interfaces, host software can upload, adjust, and back up complete drive parameter sets across Lenze 8200 vector and 8200 motec frequency inverters.
Communication and System Integration
Operating via dual physical interfaces, the 00426368 provides an RS-232 interface using a 9-pin Sub-D female connector and an RS-485 interface via plug-in screw terminals. The RS-232 connection supports point-to-point serial communication with host controllers or PCs using the LECOM-A ASCII protocol.
The 2-wire RS-485 connection uses the LECOM-B protocol to link up to 90 drive nodes in an addressable multi-drop network. Integrated bus termination resistors can be activated directly via onboard DIP switches at the physical end nodes of the network to ensure signal integrity across extended cable lengths.
Diagnostics and Status Indication
Onboard status LEDs deliver immediate visual confirmation of power status and active serial communication. Module readiness is signaled by the green PWR LED, while serial transmission and reception activity is indicated by flashes on the dual-color COM LED.
Detailed status monitoring can be performed by reading the LECOM status register via Global Drive Control (GDC) software or by viewing diagnostic menus on an attached E82ZBC keypad module on the host drive.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| PWR / Ready | Green - Solid Green / Off | Solid Green indicates supply voltage is present and module is operational. Off indicates missing supply voltage or hardware failure. |
| COM / RxD/TxD | Yellow/Red - Flashing / Off | Flashing indicates active data frame transmission or reception. Off indicates communication is idle or serial link is interrupted. |
Replacement and Spare Part Considerations
The E82ZAFC001 function module acts as a drop-in hardware replacement for communication expansion across Lenze 8200 vector and motec drives. Because all network identity settings are established via hardware DIP switches, swapping a module requires no direct parameter transfer or firmware downloading to the module.
Before installing a spare module, note the exact DIP switch configurations on the original board, duplicate those switch positions on the replacement unit, and insert the unit firmly into the drive FIF slot while the system is powered off.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| CE0 | Communication fault - Function module slot | Communication breakdown between host frequency inverter and function module in FIF slot. | Function module improperly seated; severe mechanical vibration; internal board connector fault; defective module hardware. | Verify module is fully seated in FIF slot. Inspect pins for damage. If connection is good and fault persists, replace module. |
| CE1 | LECOM communication time-out | Serial communication timeout over LECOM interface during active operation. | Disconnected or broken communication cable; incorrect baud rate or station address set on DIP switches; master host system stopped transmitting. | Check cable connection and wiring; verify DIP switch settings for baud rate and bus address match host configuration; check master PLC/PC program. |
Frequently Asked Questions
What software is used to connect to a drive through the Lenze 00426368 LECOM module?
Drive commissioning and parameter adjustments via the module are performed using Lenze Global Drive Control (GDC) or GDC Easy software over RS-232 or RS-485 connections.
Does a replacement E82ZAFC001 module require software parameter loading before installation?
No software downloading directly to the module is required. System settings such as station address, baud rate, and termination are configured directly on the module using hardware DIP switches.
How many drives can be connected on an RS-485 LECOM network using this module?
Up to 90 frequency inverters can be networked together in a multi-drop configuration using the RS-485 (LECOM-B) interface.
What does fault code CE0 indicate on a Lenze 8200 drive?
Fault code CE0 indicates a communication breakdown between the host inverter and the module in the FIF slot, often caused by loose seating, pin damage, or internal board failure.
What do the LEDs on the E82ZAFC001 module indicate during operation?
A solid green PWR LED shows that 5 V DC internal power is present and the module is healthy. A flashing yellow/red COM LED indicates active data transmission or reception.
