Lenze EMF2102IBCV001 LECOM-A/B Communication Module

LECOM-A/B serial module for PC and PLC links

The Lenze EMF2102IBCV001 is a LECOM-A/B communication module that adds an RS232 and an RS485 serial interface to a Lenze inverter through its AIF interface. The Lenze LECOM protocol is open, and the catalogue notes that components supporting it exist for various control systems. The 2002 catalogue lists the earlier EMF2102IB-V001 and names EMF2102IBCV001 as its descendant, while the 9300 system manual lists EMF2102IBCV001 as a communication module option for the 9300 servo range. Lenze shows both 8200 vector and 9300 under previous products, so this is a legacy module; confirm availability before ordering.

Technical specifications

RS232 or RS485

The LECOM-AB module has both interfaces. RS232 (LECOM-A) is a point-to-point link of up to 15 m to a PC, typically for parameter setting with the Lenze Global Drive Control software. RS485 (LECOM-B) allows a line of up to 32 devices per bus segment, with repeaters extending the network to 90 slaves. Three LEDs on the module show the communication status.

Ordering notes

The same catalogue lists the sister modules EMF2102IB-V002 for RS485 only (LECOM-B) and EMF2102IB-V003 for optical fibre (LECOM-LI), each with a descendant EMF2102IBCV002 and EMF2102IBCV003 named. Make sure you choose the variant with the interface you need. The catalogue states that the descendant products were still being developed at publication, so confirm the current code against your inverter’s documentation.

Planning a LECOM link

Check three points before ordering: the interface you need (RS232 for a PC, RS485 for a bus), the host inverter family with its AIF slot, and the controller or software that will talk LECOM A/B V2.0. The module accepts an external 24 V supply of up to 80 mA, which is needed if the serial link must stay alive with the inverter’s mains switched off. Keep cable lengths within 15 m for RS232 and plan terminations on RS485 lines.

Documents and quotation

The attached Lenze catalogue (FU 8200 vector en 11/02) gives the LECOM-AB data; the 9300 servo system manual (EDSVS9332S) lists EMF2102IBCV001 among the plug-in communication modules. See Automation Accessories for related parts. For a quotation, state the full order code, the inverter type it will be fitted to and the quantity, and confirm the current edition and compatibility with your inverter’s hardware and software version before ordering.

Where the EMF2102IBCV001 Fits in the Lenze Drive Family

On the official Lenze website, both the 8200 vector and the 9300 series appear in the previous products – inverters section. Lenze describes the 8200 vector as a modular frequency inverter for standard applications covering 0.25 to 90 kW, with pluggable function modules for integration into the control and automation architecture of a machine, and operation via the Keypad XT or a PC running the Global Drive Control (GDC) easy software. The 9300 range is described as servo inverters from 0.37 to 75 kW in four versions (servo inverter, position controller, servo cam and register controller) with pluggable AIF communication modules for fieldbus integration.

The EMF2102IBCV001 belongs to this AIF (Automation InterFace) generation of plug-in modules. Because these drives are legacy products, the module is mainly needed today to keep installed machines running, to replace a failed communication card or to restore a PC service link to an existing drive.

How the LECOM-A/B Module Works

LECOM is Lenze’s own serial communication protocol. The EMF2102IBCV001 converts the inverter’s internal AIF interface into two physical serial interfaces:

• LECOM-A (RS232) – a point-to-point connection, typically from a laptop or service PC running Lenze parameterisation software, for reading and writing codes, saving parameter sets and diagnosing faults.
• LECOM-B (RS485) – a two-wire multi-drop line on which a PLC, HMI or PC master addresses several drives in turn by their station address.

The master sends ASCII telegrams to read or write a Lenze code; the addressed drive answers with the value or an acknowledgement. Because the protocol is open and well documented, it was widely supported by PLCs and HMI panels of its time, which is why many older installations still rely on LECOM links.

Selection & Ordering Guide for the EMF2102IBCV001

• Confirm that the host drive has an AIF slot (for example 8200 vector or 9300) and record the drive’s full type code and hardware/software version from its nameplate.
• Decide which interface you actually need: the EMF2102IBCV001 combines RS232 and RS485; the sister variants are RS485-only or fibre-optic.
• Check that the master device (PLC, HMI or PC software) supports LECOM A/B and that the baud rate and station addresses can be matched.
• If the serial link must stay active with the drive mains off, plan the external 24 V DC supply.
• For a new installation rather than a repair, discuss a current Lenze inverter and fieldbus with our team, since the 8200 vector and 9300 are listed by Lenze as previous products.

Installation & Maintenance

• Switch off and isolate the inverter and wait for the DC bus to discharge before plugging or removing any AIF module, following the safety instructions in the Lenze operating instructions.
• Use shielded twisted-pair cable for RS485, connect the shield properly and terminate the line at both ends. Keep RS232 cables short and away from motor cables.
• After replacement, set the station address and baud rate to match the original configuration, then use the module LEDs to check that communication is running.
• Keep a saved copy of the drive parameter set, so that a replacement module or drive can be returned to service quickly.

Typical Applications in Oman & the GCC

Lenze 8200 vector and 9300 drives with LECOM links are still found on packaging and bottling lines, conveyors and materials-handling systems, printing and converting machines, and process skids built in the late 1990s and 2000s. In Oman and the wider GCC, maintenance teams in food and beverage plants, water and desalination facilities, building-material factories and logistics centres often need an EMF2102IBCV001 to restore a serial connection between a legacy PLC or SCADA and the drives without redesigning the control system.
