Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV552_4B is a 5.5 kW frequency inverter from the 8200 Vector product family, engineered to provide precise motor speed and torque control in demanding industrial automation applications. Designed for 3-phase line supplies operating between 320 V AC and 528 V AC, this compact panel-mount inverter module delivers up to 13 A of continuous output current with a mains input current rating of 14 A. The drive housing features an IP20 protection rating and integrates a built-in brake chopper, enabling efficient dynamic braking without requiring additional external power units. The inverter supports multiple control modes to match varied operating conditions, including linear V/f control, quadratic V/f control, sensorless vector control, and closed-loop vector control when equipped with an encoder feedback module.
Connecting and integrating the drive into an automated system is achieved through the modular plug-in architecture characteristic of the 8200 Vector series. The base unit accepts interchangeable plug-in function modules for custom digital and analog I/O expansion, as well as fieldbus option cards for CANopen, PROFIBUS-DP, DeviceNet, and INTERBUS networks. When commissioning a spare unit, existing parameters stored in non-volatile EEPROM memory—which supports up to four switchable internal parameter sets—must be transferred to the replacement drive. This configuration procedure is performed using either the optional E82ZBC001 XT Keypad or Lenze Global Drive Control (GDC) PC software. Because a replacement unit requires matching parameters and module configurations before going into service, ABC Industrial Parts can assist maintenance teams in sourcing and preparing ready-to-install replacement hardware.
Diagnostic conditions and drive readiness are indicated locally via a dual-color Red/Green Status/TRIP LED, which shows power supply status, operational readiness, and fault states. Detailed fault logbook data and numerical trip codes are accessible through the E82ZBC001 XT Keypad or via the GDC PC software diagnostic window, while status words can be polled over active fieldbus connections and critical fault conditions can trigger a dedicated relay output. First-line troubleshooting involves checking input phase line voltages, motor power wiring for short circuits or ground faults, external braking resistors, and ambient cooling conditions surrounding the heat sink. When internal micro-controller or memory errors occur that cannot be cleared through parameter restoration, internal hardware faults are not field-serviceable, making drive module replacement or expert repair through ABC Industrial Parts the most reliable pathway to restore production.

Programming and Configuration
Parameter management for the Lenze E82EV552_4B relies on non-volatile EEPROM memory integrated into the inverter module. The device stores up to four independent internal parameter sets, allowing multi-purpose machines to switch between distinct operating profiles without requiring manual parameter re-entry or external re-programming.
Engineers and maintenance technicians can configure, back up, and copy parameter sets using the Lenze Global Drive Control (GDC) PC software or directly at the drive using the optional E82ZBC001 XT Keypad. Uploading and saving parameter files prior to replacing a damaged unit ensures that motor parameters, ramp times, and network address settings are restored accurately to the replacement drive.
Communication and System Integration
The modular design of the 8200 Vector series enables flexible integration across diverse industrial fieldbus networks. The power base unit utilizes interchangeable plug-in function modules that define the terminal functionality, control interface, and fieldbus communication protocol for the inverter.
By selecting the corresponding plug-in module, the E82EV552_4B can communicate over CANopen, PROFIBUS-DP, DeviceNet, or INTERBUS communication networks. These option cards support central reference speed transmission, real-time control commands, status monitoring, and fieldbus diagnostic word evaluation by a higher-level PLC.
Diagnostics and Status Indication
The Lenze E82EV552_4B provides built-in visual and software diagnostic tools for monitoring drive operation and fault troubleshooting. A front-panel dual-color Red/Green Status/TRIP LED indicates mains power availability, operational readiness, and active TRIP error states.
For complete fault diagnostics, historical TRIP logbooks and specific error codes can be displayed on the optional E82ZBC001 XT Keypad or within the diagnostic window of the Lenze Global Drive Control (GDC) PC software. A dedicated relay output also signals drive TRIP conditions directly to external safety and control circuits.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Status/TRIP | Red/Green - Solid or Flashing | Indicates power supply status, operational readiness, and active TRIP fault states |
Replacement and Spare Part Considerations
When replacing an E82EV552_4B inverter, technicians must verify that the substitute unit matches the 5.5 kW power rating and 320–528 V AC input voltage specifications. In addition to securing the base power unit, existing plug-in option cards—such as fieldbus modules or standard I/O function modules—must be unclipped from the failed unit and installed onto the replacement drive to ensure complete wiring and network compatibility.
Because new or replacement inverters do not contain customer-specific machine settings, parameter configuration must be transferred prior to operating the drive. Parameters saved in internal EEPROM memory should be restored using Lenze Global Drive Control (GDC) software or copied directly using the E82ZBC001 XT Keypad. For modernizing legacy panels, the Lenze i550 Cabinet Inverter series serves as the recommended successor drive product line.
