Product Information
The Lenze 422228.002 (Model E82EV000-0B000CP) is a frequency inverter base control module from the Lenze 8200 Vector drive series. Designed as a modular control unit without an integral power stage, this module provides precise speed and torque control for AC asynchronous motors using V/f characteristic control or Sensorless Vector Control (SLVC). The component features a Cold Plate (CP) mounting configuration, enabling passive thermal management by attaching directly to external heat sinks or cabinet cooling surfaces. This space-saving thermal design makes it suitable for compact electrical enclosures across packaging machinery, material handling systems, textile manufacturing, and automotive assembly lines.
Integrating the Lenze 422228.002 into an automated control architecture is handled through dedicated plug-in interface slots designed to accept Lenze E82ZAF series function modules. These modular interface cards support fieldbus networking over PROFIBUS-DP, CANopen, INTERBUS, and LECOM RS-232/485 serial communication. Commissioning a replacement unit requires restoring the parameter structure stored in non-volatile EEPROM memory, which holds dual parameter sets. Technicians can transfer configuration profiles from a backup file using Lenze Global Drive Control (GDC) software or directly copy settings on site using a Keypad XT (E82ZBC) operator panel. When swapping out a damaged unit, the existing fieldbus module must be transferred to the replacement, and fresh thermal conductive compound must be applied to the rear Cold Plate interface. ABC Industrial Parts can assist maintenance teams with parameter backup files and donor unit preparation to minimize machine downtime during drive replacements.
Diagnostic oversight for the Lenze E82EV000-0B000CP is provided through visual front-panel status indicators and comprehensive internal monitoring functions. Green and red LEDs give immediate visual status, where a steady green light indicates normal drive enable status and a flashing or solid red light flags warnings or active TRIP conditions. Detailed diagnostic registers (C0168 and C0170) store error log history accessible via the Keypad XT module or the GDC software diagnostic window. Fault codes such as OC1 (short circuit), OU (DC bus overvoltage), OH (heatsink overheating), or P12 (parameter data error) help identify external wiring, thermal, or setup issues. When internal hardware self-test errors like code H05 occur, the board-level failure cannot be serviced in the field; installing a tested exchange module from ABC Industrial Parts offers a fast and reliable pathway back to full production.

Programming and Configuration
The Lenze 422228.002 frequency inverter module utilizes an internal non-volatile EEPROM memory structured to store up to two distinct parameter profiles. Configuration can be performed using Lenze Global Drive Control (GDC) software connected via a serial interface, or locally using the plug-in Keypad XT (E82ZBC) module. The dual parameter set architecture allows versatile drive tuning and multi-mode operation within a single physical controller.
During commissioning or spare unit installation, drive parameters can be quickly uploaded, downloaded, or modified. In the event of parameter memory corruption or corrupted startup data (indicated by fault code P12), a complete parameter reset to factory defaults can be performed via code C0002 before re-downloading saved parameter files (.gdc). This parameter transfer ensures that motor control algorithms, current limits, and ramp times match the original operating specifications.
Communication and System Integration
System integration for the E82EV000-0B000CP is built upon a modular architecture. The base unit includes dedicated multi-pin module slots that accommodate the Lenze E82ZAF series plug-in communication modules. This design allows the base inverter controller to be configured for a variety of fieldbus networks without replacing the core drive control hardware.
Supported protocols include PROFIBUS-DP, CANopen, INTERBUS, and LECOM RS-232/485 serial interfaces. These modules allow direct real-time control register access, control word transmission, and status monitoring from an overarching controller or PLC. Network health is monitored continuously, triggering fault codes such as CE0 upon system bus communication timeouts or CE1 if communication with the plug-in function module itself is interrupted.
Diagnostics and Status Indication
The Lenze 422228.002 features dual LED status lights on its front fascia to provide clear drive status indication. The green LED indicates operation and ready status, glowing solid when the drive is enabled and flashing when controller inhibit is active or the unit is in a ready state. The red LED indicates fault conditions, lighting solid or flashing depending on the specific trip severity or warning frequency.
Advanced diagnostic feedback is recorded within dedicated internal memory addresses, specifically parameter codes C0168 and C0170, which hold detailed fault history records. Maintenance engineers can interrogate this error log using the Keypad XT module or through the real-time diagnostic window in Global Drive Control (GDC) software, allowing rapid evaluation of operational trips and fieldbus communication issues.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Red LED | Red - Solid / Flashing | TRIP active / Fault state. Flashing indicates warning or active trip depending on flash frequency. |
| Green LED | Green - Solid / Flashing | Operation / Ready status. Continuous green indicates drive enabled; flashing green indicates controller inhibit or ready for operation. |
Replacement and Spare Part Considerations
Replacing an existing Lenze 422228.002 (E82EV000-0B000CP) requires careful transfer of both hardware accessories and saved parameters. Because this is a Cold Plate (CP) module, proper thermal dissipation relies entirely on direct contact with an external cooling surface or heat sink. During replacement, old thermal conductive paste must be thoroughly cleaned off the mounting surface and a fresh layer applied before securing the new unit.
In addition to physical mounting, the plug-in E82ZAF communication module must be unclipped from the faulty controller and installed onto the replacement base unit. After seating the module, parameters must be transferred from backup using GDC software or the Keypad XT module. When looking for a modern upgrade path, Lenze recommends the i550 cabinet inverter series as a successor solution for long-term migration strategy.

Frequently Asked Questions
What is the main characteristic of the Lenze 422228.002 Cold Plate mounting design?
The Cold Plate (CP) mounting design allows passive thermal dissipation by mounting the module directly onto an external heat sink or liquid cooling surface, reducing space requirements in compact electrical cabinets without relying on integral drive fans.
How are parameters transferred when replacing a Lenze E82EV000-0B000CP module?
Parameters can be transferred by saving and loading backup files (.gdc) using Lenze Global Drive Control (GDC) software, or by copying the stored parameter set directly from non-volatile EEPROM memory using the Keypad XT (E82ZBC) operator panel.
Which fieldbus communication options are supported by the Lenze 422228.002?
Fieldbus communication is enabled by inserting optional Lenze E82ZAF series plug-in modules, which support PROFIBUS-DP, CANopen, INTERBUS, and LECOM RS-232/485 protocols.
What action should be taken if fault code P12 appears on startup?
Fault code P12 indicates a parameter data error. To resolve it, reset the unit to factory defaults using code C0002 and reload the saved parameter set. If the fault persists, it points to a defective internal EEPROM hardware failure.
What does fault code H05 indicate on the Lenze 8200 Vector inverter?
Fault code H05 signifies an internal hardware error detected during microprocessor or memory self-tests. Because this board-level failure is not field-serviceable, the module must be returned for repair or replaced with a tested exchange unit.
