Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVHCE1524SB0 is a 1.5 kW frequency inverter from the 8400 Highline C model range within the Inverter Drives 8400 family. Operating on a 3-phase 400/480 V AC supply with a continuous output current of 3.9 A, this IP20 enclosure unit is engineered for control cabinet mounting. It provides controlled motor regulation using V/f characteristic control, sensorless vector control (SLVC), sensorless synchronous motor control (SLPSM), or closed-loop feedback vector control. Designed for precise drive applications such as packaging machinery, material handling conveyors, hoists, rotary tables, and multi-axis synchronized positioning systems, it incorporates Safe Torque Off (STO) functional safety directly into the drive hardware.
Interfacing the E84AVHCE1524SB0 with a plant system is facilitated by an integrated CANopen system bus along with an expansion slot that accepts optional fieldbus modules for PROFINET, PROFIBUS-DP, EtherCAT, or EtherNet/IP. Physical I/O connections include 8 digital inputs, 4 digital outputs, 2 analog inputs, and 2 analog outputs. Commissioning a spare drive or replacing an existing unit is streamlined by a removable pluggable memory key module. This memory key stores drive parameters, network node addresses, and custom function block programs, permitting tool-free parameter restoration and device swapping on the production floor without connecting a PC. Support from ABC Industrial Parts can help ensure parameter profiles and hardware configurations match your existing machine setup when restoring drives.
Diagnostic information is provided through four status LEDs located on the front cover, indicating operational and fault states for both the drive and the CANopen bus. Detailed diagnostics and parameter readouts are available using the plug-in Keypad XT (E84DGFCE) or via EASY Starter software connected through a USB Diagnostic Adapter (E84AYCER). Internal logging maintains a fault history logbook recording recent operating events. While field faults such as motor overloads (OC5), DC-bus overvoltage (OU), or external wiring faults can be resolved by checking mechanical loads and line connections, internal power stage faults (OC1) or hardware self-test failures (FAIL) indicate internal hardware damage. In such instances, board-level repairs or obtaining a fully tested replacement from ABC Industrial Parts offers a dependable path to restore operational availability.

Programming and Configuration
Drive parameterization and positioning configuration for the Lenze E84AVHCE1524SB0 are performed using Lenze engineering tools such as EASY Starter and L-force Engineer software. The drive supports up to 15 distinct positioning profiles, internal profile generators, and homing routines directly on board, reducing the processing workload on higher-level motion controllers.
Hardware interaction for programming and commissioning can be conducted through the Keypad XT (E84DGFCE) mounted to the front interface or via a PC connected with the USB Diagnostic Adapter (E84AYCER). Drive parameters, network addresses, and function block programs are written directly to a removable memory key module, enabling fast parameter transfer between drives without requiring software tools on the factory floor.
Communication and System Integration
The Lenze 8400 Highline C inverter includes an integrated CANopen system bus interface as standard for system networking and multi-axis coordination. The CANopen interface handles operational communication and system diagnostics across connected automation components.
For integration into broader industrial networks, the E84AVHCE1524SB0 features an expansion slot for optional fieldbus communication modules. Supported modules include PROFINET (E84AYCPR / E84AYCPM), PROFIBUS-DP (E84AYCPM), EtherCAT (E84AYCEC), and EtherNet/IP (E84AYCEO), allowing seamless communication with various master PLC architectures.
Diagnostics and Status Indication
System state evaluation is provided by front cover LEDs indicating drive operating status and CANopen bus performance. Operational parameters and active fault records can be accessed through the Keypad XT module or monitored via EASY Starter software.
The drive maintains an internal fault history logbook buffer to record recent fault events, enabling systematic troubleshooting of transient trips and operational interruptions.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRV-RUN | Drive operation and status indicator | |
| DRV-ERR | Drive fault and error indicator | |
| CAN-RUN | CANopen system bus operational status | |
| CAN-ERR | CANopen system bus error status |
Replacement and Spare Part Considerations
When replacing a Lenze E84AVHCE1524SB0 frequency inverter, verify that the spare unit matches the exact part number and electrical ratings of 1.5 kW output power and 3.9 A continuous output current. Ensure that any installed communication expansion modules from the original unit are correctly transferred to the replacement drive's extension slot.
Device configuration transfer is streamlined by the pluggable memory key. Moving the memory key from the original unit to the spare drive restores parameter profiles, fieldbus node settings, and custom function block logic without needing a PC connection. For future equipment upgrades, the Lenze i550 cabinet inverter serves as the recommended successor model.
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 or severe overcurrent condition detected on motor output phases. | Short circuit in motor cable or motor winding, ground fault, or drive output power stage failure. | Check motor and motor wiring for short circuits and phase isolation. If fault persists with motor disconnected, internal power stage is damaged (return unit for repair). |
| OC2 | Earth fault | Ground fault / earth current detected at inverter output. | Insulation fault in motor winding or motor cable, excessive cable capacitance. | Check insulation resistance of motor and motor cable to earth ground. Inspect cable length and screening. |
