Product Information
The Lenze E82EV551-2C is a 0.55 kW frequency inverter from the Lenze 8200 Vector series, engineered for precise motor speed and torque regulation in cabinet-mounted industrial systems. Operating on a single-phase or two-phase 230 V AC supply ranging from 180 V to 264 V AC across 45 to 65 Hz, this compact IP20 unit delivers a continuous output current of 3.0 A with a 150% overload capacity reaching 4.5 A for up to 60 seconds. Designed for high dynamic performance, the drive supports Sensorless Vector Control (SLVC) alongside linear and quadratic V/f characteristic modes, providing adaptable control for standard 4-pole AC asynchronous motors across an output frequency range of 0 to 480 Hz with an 8 kHz switching frequency and 40 W power loss.
Integrating a replacement unit into an existing line requires proper alignment of the drive communication and parameter profiles. The E82EV551-2C features a modular architecture with a Function Module interface (FIF) slot, allowing quick installation of optional fieldbus interface modules including PROFIBUS-DP (E82ZAFPC), DeviceNet (E82ZAFDC), INTERBUS (E82ZAFIC), and LECOM RS232/RS485 (E82ZAFAC). Native networking is supported via terminal block X4 through the integrated CAN system bus at baud rates up to 500 kbit/s. Commissioning a replacement unit requires transferring saved parameters into the drive, which stores two complete parameter sets in its internal non-volatile EEPROM. Using either the optional Keypad XT (E82ZBC) or Lenze Global Drive Control (GDC) software, technicians can clone parameters directly from a donor unit or software backup to restore operation. ABC Industrial Parts provides tested replacement units and technical support to assist with parameter extraction and drive configuration.
System status and operating conditions are indicated on the drive front panel by dedicated status LEDs. A solid green LED confirms the drive output is enabled and ready, while a flashing green LED indicates controller inhibit; a solid red LED indicates an active inverter trip fault, and a flashing red LED signals an active warning. Detailed fault diagnostics can be accessed via parameter C0161 for active trip codes and parameter C0168 for the trip history buffer, viewable using the Keypad XT module or GDC software. First-line troubleshooting should verify mains supply voltage, check motor wiring and ground insulation, inspect cooling fins to prevent heatsink overtemperature, and ensure proper 120-ohm bus termination on CAN system lines. When unresolvable internal faults occur, such as EEPROM memory errors or control board failures, component-level field repairs are not feasible, and installing a tested exchange drive from ABC Industrial Parts offers a fast route back to production.

Programming and Configuration
Parameter setup and drive commissioning for the Lenze E82EV551-2C are carried out using Lenze Global Drive Control (GDC) engineering software or directly through the optional Keypad XT (E82ZBC) pluggable operating module. The drive hardware contains non-volatile EEPROM memory configured to store two independent parameter sets (Parameter Set 1 and Parameter Set 2). This dual-set capability allows technicians to maintain primary operation parameters along with an alternative operating mode or a factory backup configuration directly on the unit.
During replacement procedures, parameter profiles can be copied directly using the Keypad XT parameter transfer function or loaded from a saved PC backup file via GDC software using a LECOM RS232/RS485 module (E82ZAFAC). Essential adjustable parameters include motor nameplate configuration, acceleration and deceleration ramp settings, V/f curve selection, and system monitoring settings. Active fault conditions can be viewed in parameter C0161, while historical events are stored in the trip history buffer at parameter C0168.
Communication and System Integration
The E82EV551-2C inverter includes an integrated CAN system bus interface connected at terminal block X4. Supporting data transmission speeds up to 500 kbit/s, this integrated connection enables multi-drive networking, master-slave synchronisation, and direct process data PDO exchange between interconnected Lenze drives without requiring additional fieldbus hardware.
For integration into broader plant networks, the base drive includes a standard Function Module interface (FIF) slot. Pluggable option modules can be fitted into the FIF slot to interface directly with higher-level controllers. Supported fieldbus options include PROFIBUS-DP (E82ZAFPC), DeviceNet (E82ZAFDC), INTERBUS (E82ZAFIC), and LECOM RS232/RS485 (E82ZAFAC).
Diagnostics and Status Indication
Operational diagnostic feedback on the Lenze E82EV551-2C is provided by two front-mounted status LEDs along with diagnostic parameters accessible via software or keypad interfaces. The status LEDs give immediate visual feedback on power supply presence, drive enablement, warning conditions, and active trip faults.
Detailed fault analysis is supported by parameter C0161, which displays the active trip code, and parameter C0168, which logs historic fault events. These diagnostic parameters can be inspected on the Keypad XT display or monitored in real time using the diagnostic window within Lenze Global Drive Control (GDC) engineering software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (Ready) | Green - Solid/Flashing | Solid ON: Drive ready and output enabled. Flashing: Drive ready, output inhibited. OFF: Supply voltage missing or internal power supply failure. |
| Red LED (Trip) | Red - Solid/Flashing | Solid ON: Inverter trip fault active. Flashing: Warning or controller inhibit active. OFF: Normal operation without fault. |
Replacement and Spare Part Considerations
When replacing an existing Lenze E82EV551-2C drive, matching both hardware and software configurations is vital for successful recommissioning. Ensure the replacement inverter matches the 0.55 kW rating and single/two-phase 230 V input requirement. If the original installation utilizes a communication option such as PROFIBUS-DP or LECOM, remove the option module from the FIF slot of the existing drive and transfer it to the replacement unit.
A replacement drive delivered from stock will contain default parameters and must be parameterized before enabling the motor output. Transfer saved parameters using either the Keypad XT module or GDC software. If terminal X4 system bus networking is utilized, confirm that 120-ohm bus termination resistors are correctly placed at the end nodes. Although Lenze has introduced the i500 series (such as i510 and i550) as modern successors, direct replacement with an E82EV551-2C unit avoids panel mechanical redesigns and software modification.
