Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV551_2B is a cabinet-mounted frequency inverter from the 8200 Vector series, engineered to deliver precise speed and torque control for three-phase AC motors rated up to 0.55 kW (0.75 HP). Operating on a supply voltage range of 180 to 264 V AC at 45 to 65 Hz, this compact drive converts incoming single-phase or three-phase power into a controlled 0 to 230 V AC three-phase output. It supports a continuous output current of 3.0 A, with peak acceleration current reaching 4.5 A to handle high-inertia starting conditions. Designated as a variant manufactured without an internal RFI filter, this drive allows panel builders flexibility in configuring external filtering and system EMC architecture within centralized enclosures.
Integrating a replacement unit into an active control system requires matching hardware modules and transferring drive parameters. The E82EV551_2B features a modular construction where control electronics separate from the power unit, enabling insertion of functional modules such as the E82ZAFCC for CANopen or E82ZAFPC for PROFIBUS-DP. Parameter configurations are held in non-volatile memory supporting four distinct parameter sets (PAR1 through PAR4). Setup can be completed using the plug-in E82ZMC memory card for rapid drive cloning, the E82ZBC Keypad XT operator panel, or Lenze Global Drive Control (GDC) software connected via a PC interface. ABC Industrial Parts can assist maintenance teams with fully tested spare units and compatible modules to streamline parameter restoration and commissioning.
System diagnostic data is provided on the drive front panel and through connected diagnostic tools. Dual status indicators—a green Operation LED and a red TRIP LED—display current operational states and fault activity. When a fault is triggered, the inverter disables motor output and logs the event in an internal buffer storing the last four TRIP occurrences. Errors such as OC1 (overcurrent), OU (DC bus overvoltage), LU (DC bus undervoltage), and OH (heatsink overtemperature) typically relate to field wiring, line supply, or mechanical load conditions. Hardware failures like memory corruption (code EE) or excessive internal temperature (code OH7) indicate internal hardware faults where field servicing is not possible, making direct drive replacement or repair through ABC Industrial Parts the most reliable solution to restore production.

Programming and Configuration
Parameter management on the Lenze E82EV551_2B is structured around internal EEPROM memory capable of retaining up to four independent parameter sets (PAR1 through PAR4). This allows multi-recipe machine configurations to be stored directly on the drive. Control algorithms can be configured for standard V/f performance, sensorless vector control, or closed-loop vector control depending on application requirements.
Drive configuration can be executed using either the pluggable E82ZBC Keypad XT panel or Lenze Global Drive Control (GDC) engineering software over a serial PC connection. For rapid unit cloning without connecting setup software, the removable E82ZMC memory card provides plug-and-play parameter transfer. Transferring a programmed card into a replacement drive loads all operating parameters instantly. If parameter corruption occurs or a clean setup is required, entering parameter value C0009=1 re-initializes the drive back to factory settings.
Communication and System Integration
The modular construction of the Lenze 8200 Vector series separates core power functionality from network communication interfaces. The E82EV551_2B integrates into industrial networks by attaching fieldbus-specific function modules directly into the front option slot.
Supported communication adapters include the E82ZAFCC CANopen function module and the E82ZAFPC PROFIBUS-DP function module, alongside optional interfaces for DeviceNet and INTERBUS networks. These modules grant master PLCs full control over drive enable, velocity reference commands, real-time operating data, and remote parameter adjustment.
Diagnostics and Status Indication
Real-time diagnostic visual indication is handled via two LED indicators on the inverter faceplate. The green Operation LED indicates general drive status including ready state, active output run, or controller inhibit. The red TRIP LED illuminates solid or flashes when an operational fault causes output shutdown.
Detailed fault analysis is accessible through the E82ZBC Keypad XT display panel or the Global Drive Control software online diagnostic screen. The inverter maintains a non-volatile fault history buffer that logs the last four TRIP conditions to aid in troubleshooting intermittent process interruptions.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| TRIP | Red - Flashing / Solid | Fault condition detected; drive output disabled |
| Operation | Green - Solid / Flashing | Drive status indication (Ready / Operating / Inhibit) |
Replacement and Spare Part Considerations
Before installing a replacement E82EV5512B, confirm that the part number matches the original hardware specifications. Because the '2B' suffix designates a unit built without an internal RFI filter, verify that appropriate external line filters are installed in the control cabinet to maintain required EMC compliance.
When swapping out a damaged unit, remember to transfer all attached function modules, such as the CANopen or PROFIBUS adapter cards, to the replacement chassis. Ensure power is completely isolated before unseating or installing modules.
Commissioning a replacement drive requires reloading application settings. If the original installation utilizes an E82ZMC memory card, transferring the card to the replacement drive copies all parameter sets directly. Alternatively, upload stored parameter backup files via Global Drive Control software or manually program the unit using the Keypad XT module.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| OC1 | Short circuit / Overcurrent | Short circuit at motor output or instantaneous overcurrent threshold exceeded. | Short circuit in motor cable or motor winding, excessive acceleration ramp, ground connection error. | Check motor and motor cables for short circuit; check acceleration time settings. |
| OC2 | Earth fault | Ground fault / earth leakage current detected on motor phases. | Ground fault in motor insulation, damaged motor cable, capacitive cable currents due to long cable run. | Check motor windings and supply cables for earth isolation; reduce switching frequency or add output filter. |
| OC5 | Ixt overload (Inverter overload) | Inverter thermal overload threshold reached due to continuous high current. | Drive oversized for load, prolonged operation above continuous rated current I_N, high ambient temperature. | Check mechanical load for jam/binding; check motor sizing and duty cycle; verify cooling fan performance. |
| OU | Overvoltage DC bus | DC bus voltage exceeded upper limit threshold (approx. 400 V DC for 230 V units). | Regenerative load energy during deceleration too high, deceleration time too short, braking resistor missing or defective. | Increase deceleration ramp time; connect braking module and braking resistor if heavy braking duty. |
| LU | Undervoltage DC bus | DC bus voltage fell below lower threshold during operation or standby. | Mains voltage failure, input power dip, phase loss, defective supply fuses or contactor. | Check line supply voltage; verify supply connection and fuses. |
