Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV302_4B is a 3.0 kW frequency inverter from the 8200 Vector series, engineered to provide precise variable speed regulation and dynamic torque control for industrial three-phase asynchronous motors. Operating across a three-phase input voltage range of 320 V AC to 528 V AC at 400/480V, this compact IP20-rated inverter delivers a continuous output current of 7.3 A and supports output frequencies from 0 to 480 Hz with an 8 kHz switching frequency. Built with an integrated Class A / Category C2 radio interference filter (indicated by the _4B suffix), the unit suppresses electromagnetic interference directly within the power stage, saving enclosure space by eliminating the requirement for external RFI filter hardware. The inverter supports both sensorless vector control and programmable V/f characteristics, making it suitable for material handling systems, pump and fan control, and packaging machinery.
Featuring a modular system architecture, the E82EV302_4B separates its power section from functional interfaces, allowing customized integration through plug-in modules. Fieldbus and I/O expansion are handled via dedicated slots that accommodate standard I/O modules, CAN system bus, PROFIBUS-DP, INTERBUS, or LECOM serial modules. Commissioning a replacement unit requires restoring the process configuration, as the drive stores up to four independent, online-switchable parameter sets within internal EEPROM memory. Parameter configurations can be backed up and reloaded using the plug-in EMZ8201BB keypad module or via PC using Global Drive Control (GDC) software. When replacing a failed unit, technicians must swap the existing plug-in communication module to the spare unit and copy the parameter set to match the machine's operating parameters. ABC Industrial Parts can support maintenance teams with tested spare units and parameter extraction assistance to minimize production downtime.
Diagnostic feedback on the E82EV302_4B is provided through front-panel LEDs and digital fault reporting. A solid green indicator signals operational readiness, while a red LED illuminates continuously or flashes during active TRIP fault conditions. Detailed TRIP codes, such as OC1 (output short circuit), OU (DC bus overvoltage), OH (heatsink overtemperature), and CE0 (CAN communication error), can be read directly using the EMZ8201BB keypad or monitored live through Global Drive Control software. Internal non-volatile memory logs historical TRIP events for rapid root-cause analysis. Initial troubleshooting should include checking main supply fuses across input terminals L1, L2, and L3, inspecting motor cable insulation on U, V, and W terminals, and verifying that plug-in modules are firmly seated. Persistent power stage faults or EEPROM memory corruptions (code EER) indicate internal hardware damage that cannot be serviced in the field; in such cases, sourcing a refurbished replacement or arranging unit repair through ABC Industrial Parts provides a fast route back to full operation.

Programming and Configuration
The Lenze E82EV302_4B frequency inverter features internal non-volatile EEPROM memory for storing all operating parameters and drive settings. Up to four separate parameter sets can be saved internally and switched online during operation, allowing a single inverter to adapt to different motor profiles or process requirements without interrupting control execution.
Configuration and parameter setup are performed using either the plug-in EMZ8201BB keypad module or the Global Drive Control (GDC) PC tool. The keypad attaches directly to the front operating slot for local parameter adjustments, menu navigation, and parameter set cloning. Alternatively, GDC software connects via PC to provide complete parameter management, offline drive configuration, parameter set uploading/downloading, and real-time monitoring.
When installing a spare drive, parameter sets can be copied directly from the original unit using the keypad transfer function or loaded from a saved GDC project file on a PC. Restoring the exact motor parameters, ramp times, and fieldbus node configuration ensures that the replacement inverter matches the existing machine requirements.
Communication and System Integration
The modular architecture of the Lenze 8200 Vector series separates control and fieldbus communications from the main drive hardware. The E82EV302_4B features plug-in function slots that support various option modules, allowing the unit to adapt to multi-vendor automation architectures.
Available interface modules include the E82ZAFSC Standard I/O module for hardwired digital and analog control signals, the E82ZAFCC System Bus CAN module for integrated CANopen system networking, and the E82ZAFPC module for PROFIBUS-DP network connection. Serial communications are also supported via LECOM RS-232/485 interfaces or INTERBUS modules.
When swapping out a faulty drive, the plug-in function module can be unbolted and transferred directly to the replacement E82EV302_4B unit. Network parameters such as bus node addresses, DIP switch settings, and baud rates remain on the external module or must be verified in the parameter sets after mechanical installation.
Diagnostics and Status Indication
The front panel of the Lenze E82EV302_4B includes dual-color LED indicators for immediate visual diagnosis of operational states. A solid green LED confirms that the drive supply is normal and the inverter is ready for enable signals. A red LED illuminates solid or flashes when a TRIP fault condition occurs, signaling an active fault that disables drive output.
Detailed fault analysis is conducted via the optional EMZ8201BB keypad, which displays specific alphanumeric TRIP codes, or via Global Drive Control software connected to a PC. Historical fault logs stored in the inverter's internal EEPROM record past error codes, enabling maintenance technicians to trace intermittent trips and evaluate power supply stability, thermal loading, or motor output conditions.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready/Operation Indicator | Green - Solid | Operational state active and ready for drive enable |
| Fault/TRIP Indicator | Red - Flashing or Solid | Active fault or TRIP condition present |
Replacement and Spare Part Considerations
When replacing an existing Lenze E82EV302_4B drive, ensure the part number matches precisely, specifically verifying the _4B suffix. This suffix confirms the presence of the integrated Class A / Category C2 RFI filter. Installing an unfiltered variant in a cabinet designed for integrated filtering may cause electromagnetic noise issues on adjacent control wiring.
A replacement unit cannot be operated directly out of the box without configuration. Maintenance personnel must transfer the existing plug-in option module (such as the E82ZAFSC Standard I/O or E82ZAFCC CAN module) to the new inverter base unit. Screws holding the module must be tightened securely to prevent function slot communication errors (code CE1).
Parameter restoration is required before powering up motor loads. Parameters can be copied using the EMZ8201BB keypad module or uploaded from a computer using Global Drive Control software. Ensure that parameters such as motor rated current (C0087), acceleration/deceleration ramps (C0012/C0013), and fieldbus configurations are fully transferred.

Frequently Asked Questions
What is the function of the _4B suffix in the part number E82EV302_4B?
The _4B suffix designates that the frequency inverter includes an integrated Class A / Category C2 radio interference filter, suppressing electromagnetic noise directly within the drive and avoiding the need for an external RFI filter.
Is the Lenze E82EV302_4B inverter a direct plug-and-play replacement?
No, a replacement unit requires parameter configuration and module transfer before operation. You must transfer the plug-in function module (such as I/O or CAN module) from the old unit and restore the parameter set using the EMZ8201BB keypad or Global Drive Control (GDC) software.
How are parameter sets transferred to a spare E82EV302_4B drive?
Parameters can be saved and copied using the plug-in EMZ8201BB keypad module or downloaded directly from a saved project file using Global Drive Control (GDC) PC software.
What does error code OC1 indicate on the Lenze E82EV302_4B?
Error code OC1 indicates a short circuit or earth fault on output terminals U, V, W. If the fault persists even with the motor disconnected, it points to an internal power stage failure requiring unit replacement or professional repair.
What do the green and red LEDs on the front panel signify?
A solid green LED indicates that the drive is powered and ready for operation. A solid or flashing red LED indicates an active TRIP fault condition that disables output power.
