Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVSCE2234VB0 is a 22 kW frequency inverter from the 8400 Stateline C series designed for precise speed and torque control of three-phase AC motors across automated processing lines, material handling systems, pumps, and fans. Designed for cabinet installation with an IP20 protection rating, this drive operates on a 3-phase supply voltage of 400 V or 500 V AC (operating across a 320 V to 550 V AC supply range) and delivers a rated output current of 47 A at 400 V or 37.6 A at 500 V. Output frequencies range from 0 to 599 Hz with selectable motor control methods, including linear or square-law V/f characteristic control, Sensorless Vector Control (SLVC), and Servo VFC with encoder feedback. Built-in Safe Torque Off (STO) functional safety technology permits reliable safety circuit integration directly within the inverter, eliminating the need for redundant external motor contactors.
For machine control integration, the drive is equipped with 8 digital inputs, 4 digital outputs, 2 analog inputs, and 2 analog outputs alongside an onboard CANopen system bus interface. An integrated fieldbus option slot supports optional communication modules including PROFINET (E84AYCER), PROFIBUS-DP (E84AYCPM), EtherCAT (E84AYCET), and EtherNet/IP (E84AYCEO). Commissioning and replacing a drive in service is streamlined through Lenze's pluggable Memory Module architecture, which stores complete parameter configurations directly on a removable chip for rapid transfer without requiring a PC or engineering software. Parameterization and manual control can also be conducted using the Keypad X400 (EZAEBK1001), a USB Diagnostic Adapter (EWM8400BASE), or Lenze EASY Starter and EASY Engineer software frameworks. ABC Industrial Parts can assist maintenance teams with pre-configured replacement units or parameter transfer support.
Real-time drive status is indicated on the front panel by four status LEDs: DRIVE READY, DRIVE ERROR, CAN RUN, and CAN ERR. Advanced troubleshooting and historical error logs are accessible through the Keypad X400 or via EASY Starter software. When commissioning or diagnosing operational issues, technicians should first verify three-phase line voltage, output motor cabling, earth isolation, and 24 V logic signals on the STO safety inputs. Diagnostic codes address operational conditions such as DC-bus overvoltage, motor overtemperature, or mains supply dips, whereas internal power section failure or ASIC self-test errors indicate hardware-level degradation. When internal hardware defects prevent normal drive operation, ABC Industrial Parts offers tested exchange units and professional repair services to minimize production downtime.

Programming and Configuration
Parameter settings and operational configurations for the Lenze E84AVSCE2234VB0 are managed through the Lenze EASY Starter or EASY Engineer software suites. Direct PC connections are established via the USB Diagnostic Adapter (EWM8400BASE) or through an installed fieldbus network module. These software environments allow technicians to configure motor nameplate data, acceleration and deceleration ramps, switching frequencies (rated at 4 kHz), input/output function mapping, and control algorithms ranging from simple V/f curves to advanced Servo VFC vector control.
The inverter utilizes a pluggable Lenze Memory Module as its central hardware parameter storage medium. All drive parameters and operational profiles reside directly on this removable non-volatile chip. During device replacement, the Memory Module can be physically moved from a non-functioning drive into a replacement unit, enabling full parameter restoration without requiring software tools, PC connections, or re-commissioning work. Local adjustments and real-time parameter editing can also be performed directly at the machine using the optional Keypad X400 (EZAEBK1001).
Communication and System Integration
The Lenze E84AVSCE2234VB0 features an onboard CANopen system bus interface for networking drives within CAN-based control architectures. The native CANopen connectivity supports real-time velocity control, control commands, parameter adjustment, and cyclic feedback polling between distributed frequency inverters and a master PLC.
To accommodate broader fieldbus architectures, the drive includes a dedicated option slot on the front control section. Pluggable communication modules allow direct integration into PROFINET (E84AYCER), PROFIBUS-DP (E84AYCPM), EtherCAT (E84AYCET), and EtherNet/IP (E84AYCEO) networks. This modular expansion capability allows the drive to integrate easily into diverse industrial control systems, including material handling, automotive manufacturing, and process control applications.
Diagnostics and Status Indication
Front panel status LEDs provide visual indication of drive operational state and system bus status. The DRIVE READY LED illuminates solid green when main power is applied and the inverter is prepared for enable commands, while the DRIVE ERROR LED lights solid or flashes red when an operational fault occurs. Communication status across the onboard system bus is displayed via the green CAN RUN LED and red CAN ERR LED.
In addition to LED indicators, full diagnostic status, internal variable values, and error logs are accessible through the Keypad X400 display module or via Lenze EASY Starter software using the USB Diagnostic Adapter (EWM8400BASE). Real-time diagnostic monitoring enables maintenance personnel to check DC-bus voltage levels, heatsink temperature, motor loading (I2t calculation), and Safe Torque Off (STO) input logic status during operation.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE READY | Green - Solid | Inverter is powered and ready for operation |
| DRIVE ERROR | Red - Solid / Flashing | Inverter fault or error state detected |
| CAN RUN | Green - Solid / Flashing | CANopen system bus active state |
| CAN ERR | Red - Solid / Flashing | CANopen communication error detected |
Replacement and Spare Part Considerations
When selecting a replacement for a failed Lenze E84AVSCE2234VB0 inverter, ensure that the part number and power rating (22 kW, 400/500 V AC) match the existing unit exactly. Matching model specifications guarantees identical physical dimensions for cabinet mounting, correct terminal block sizing for power wiring, and full compatibility with installed option modules.
To transfer parameters to a new drive, extract the pluggable Lenze Memory Module from the defective unit and insert it securely into the replacement drive prior to powering up. If the original memory module is undamaged, the replacement inverter will start up with identical motor settings, digital/analog I/O configurations, and fieldbus communication parameters. If the memory module is missing or corrupt, parameter sets must be reloaded using Lenze EASY Starter and a USB Diagnostic Adapter (EWM8400BASE).
Before resuming machine operation, verify that 24 V logic signals are properly applied to the Safe Torque Off (STO) inputs. If optional communication modules (such as PROFINET or PROFIBUS-DP) are used, transfer the module to the replacement drive and verify network address settings to restore communication with the main machine controller.
