Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E82EV371_2B is a compact 0.37 kW frequency inverter from the 8200 Vector series, designed for controlled motor speed regulation of three-phase AC asynchronous motors. Operating on a single-phase or three-phase input supply voltage ranging from 180 V to 264 V AC, this drive delivers a continuous output current of 2.4 A and a maximum peak output current of 3.6 A for 60 seconds, representing a 150% overload capacity. Built into a book-style housing for cabinet installation, the drive incorporates an integrated Class A/B RFI radio interference filter to satisfy electromagnetic compatibility requirements and simplify panel wiring. Control functionality supports both linear or quadratic V/f characteristic curves and sensorless vector control with an output frequency range from 0 Hz up to 480 Hz.
Constructed with a modular system architecture, the E82EV371_2B power unit features plug-in slots for optional function and communication modules, allowing connection to systems using CANopen (E82ZAFC), PROFIBUS-DP (E82ZAFP), or LECOM RS-232/RS-485 interfaces. Commissioning a replacement unit requires configuring the drive parameters to match the operational motor and machine profile, as a bare replacement drive will not operate out of the box. Internal non-volatile EEPROM memory stores up to four complete parameter configuration sets, which can be programmed or uploaded using the optional XT Keypad E82ZBC or Lenze Global Drive Control (GDC) software via a PC interface. Where parameter extraction from a faulty board is achievable, ABC Industrial Parts can assist in transferring stored parameter sets to a replacement drive to reduce setup time.
Operational monitoring and troubleshooting on the E82EV371_2B are provided by front-panel status LEDs and digital diagnostic tools. A solid green operating state LED indicates normal ready or running status, while a flashing green LED indicates an active controller inhibit condition; a flashing red LED signals an active TRIP fault. Detailed error diagnostics can be viewed through the XT Keypad display or the real-time diagnostic monitor and fault history memory log in the GDC software. First-line field checks should verify mains supply voltage across terminals, motor insulation, output wiring, and the physical seating of communication option modules. Internal microcontroller or power section hardware failures, such as fault codes H10 or H11, cannot be serviced in the field, and procuring a fully tested exchange drive through ABC Industrial Parts provides a direct route to restoring production.

Programming and Configuration
The Lenze E82EV371_2B inverter relies on parameter-driven configuration to manage motor acceleration, deceleration, thermal protection, and operating modes. Parameters can be modified directly at the drive using the plug-in XT Keypad E82ZBC or through a computer running Lenze Global Drive Control (GDC) software connected via a PC adapter. Key timing parameters include acceleration ramp time (C0012) and deceleration ramp time (C0013), which control motor dynamic response and help prevent overcurrent or overvoltage tripping during speed transitions.
The drive features internal non-volatile EEPROM memory capable of holding up to four independent parameter sets. This multi-configuration storage allows users to maintain different operating profiles or quickly restore baseline parameters. In cases of configuration corruption or parameter transfer failure, resetting the drive to factory default settings via parameter C0002 allows technicians to establish a clean configuration baseline before re-entering application specifications.
Communication and System Integration
The E82EV371_2B frequency inverter integrates into automated networks through pluggable communication modules inserted into dedicated expansion slots on the drive chassis. Depending on system requirements, the drive can be equipped with a CANopen module (E82ZAFC), a PROFIBUS-DP module (E82ZAFP), or LECOM modules for RS-232 and RS-485 serial communications. This modular interface approach keeps base hardware compact while ensuring compatibility with standard industrial fieldbus architectures.
When connected to a network, the drive receives speed setpoints, start/stop commands, and controller inhibit signals remotely while transmitting operational status, output current, and TRIP messages back to the central controller. Proper seating of the communication module and secure fieldbus wiring are required to prevent bus faults, such as communication slot trip code CE0.
Diagnostics and Status Indication
System status and active TRIP conditions on the Lenze E82EV371_2B are indicated via visual LEDs on the front panel and digital communication tools. A steady green LED indicates that the drive is powered and ready or actively driving the motor, while a flashing green LED indicates controller inhibit mode. A flashing red LED signals an active fault condition that has tripped the drive output.
For detailed diagnostic analysis, the drive maintains an integrated fault history memory log that records recent TRIP events. Technicians can read specific fault codes, operational values, and trip conditions using the XT Keypad E82ZBC display or through the real-time diagnostic monitor built into Lenze Global Drive Control (GDC) software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Operating State LED | Green - Solid / Flashing | Steady Green = Ready/Running; Flashing Green = Controller inhibit active |
| Fault LED | Red - Flashing | Fault/TRIP condition active |
Replacement and Spare Part Considerations
When replacing a Lenze E82EV371_2B in an existing panel, exact part number matching is critical to ensure identical power ratings (0.37 kW) and input voltage compatibility (180–264 V AC). Because the 8200 Vector series uses modular plug-in function blocks, the replacement drive chassis must be fitted with the exact fieldbus or I/O module from the original drive, such as the CANopen (E82ZAFC) or PROFIBUS (E82ZAFP) module, to maintain network communication and control terminal behavior.
A replacement E82EV371_2B drive cannot operate directly out of the box without transferring the original drive's parameter configuration. Parameters stored in the non-volatile EEPROM must be uploaded via GDC software or copied using the XT Keypad E82ZBC to the new unit. If migration to current technology is preferred, Lenze designates the i510 and i550 cabinet series as the recommended successor series for 8200 Vector drives, though retrofitting requires reviewing physical mounting dimensions, terminal wiring, and fieldbus configuration.

Frequently Asked Questions
What tools are required to configure the Lenze E82EV371_2B inverter?
The inverter can be configured using the optional XT Keypad E82ZBC attached directly to the front interface slot or via a PC running Lenze Global Drive Control (GDC) software connected through a communication adapter.
Can a replacement Lenze E82EV371_2B drive be installed directly out of the box?
No, a replacement drive requires parameter configuration before operation. Motor parameters, speed ramps, and communication settings stored in the original drive's EEPROM must be transferred using the XT Keypad E82ZBC or GDC software.
What do the front panel status LEDs on the E82EV371_2B indicate?
A steady green LED indicates normal ready or running state, while a flashing green LED indicates controller inhibit active. A flashing red LED indicates an active fault or TRIP condition.
How are communication protocols such as PROFIBUS or CANopen integrated into this inverter?
The drive features a modular expansion slot that accepts pluggable function modules, including the CANopen module E82ZAFC, PROFIBUS module E82ZAFP, or LECOM RS-232/RS-485 modules.
What action should be taken if the inverter displays fault code H10 or H11?
Fault codes H10 and H11 indicate internal electronic hardware or control board failures. These internal hardware faults are not field-serviceable, requiring drive replacement or repair.
What is the recommended successor series for the Lenze 8200 Vector inverter family?
Lenze recommends the i510 or i550 cabinet series as successor drive models for replacing legacy 8200 Vector frequency inverters in panel installations.
