Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVSCE5512SX0 is a 0.55 kW frequency inverter from the 8400 StateLine C series within the L-force 8400 product family. Designed for control cabinet installation with an IP20 protection rating, this drive operates on a 1-phase or 3-phase AC input supply ranging from 180 V AC to 264 V AC, producing a 0 to 230 V AC output with a continuous rated output current of 3.0 A and a maximum short-term output current of 4.5 A. It supports linear V/f, square-law V/f, sensorless vector control (VFCplus), and sensorless synchronous motor control (SLVC) modes across an output frequency range of 0 to 599 Hz with an 8 kHz switching frequency. Integrated Safe Torque Off (STO) functionality conforming to SIL 3 according to EN IEC 62061 and Performance Level e according to EN ISO 13849-1 provides certified safety suppression directly in the drive hardware.
For integration and commissioning, the unit features built-in CANopen system bus connectivity alongside control terminals providing 5 digital inputs, 1 digital output, 1 relay output, 1 analog input, and 1 analog output. Machine parameter settings are stored on the plug-in L-force Memory Module E84AYM01S, enabling tool-free parameter replication and rapid drive swapping without needing a PC connection. When software configuration or online monitoring is required, the front X400 diagnostic port accepts the EZAEBK100 keypad or the EZAEAG0001 USB diagnostic adapter for direct connection to Lenze EASY Starter software V2.0 or higher. When preparing a spare inverter, configuration extraction or parameter alignment can be verified with support from ABC Industrial Parts before restoring the drive to production service.
Diagnostic monitoring is handled through front panel status LEDs and internal parameter C00160 for active error reading. The DRV-READY and DRV-ERR LEDs communicate drive operating states and error conditions, while CAN-RUN and CAN-ERR report CANopen system bus activity. Common operational faults include OC1 for output short circuits or earth faults, OC2 for overcurrent during deceleration, OU for DC bus overvoltage, LU for undervoltage, OH for heatsink overtemperature, and CE0 for CAN communication errors. A persistent H05 code or solid red DRV-ERR indication indicates an internal hardware fault that cannot be cleared through field parameter adjustment. In these scenarios, replacing the unit or sourcing a fully tested exchange drive through ABC Industrial Parts offers a fast resolution to minimize process downtime.

Programming and Configuration
Drive configuration for the Lenze E84AVSCE5512SX0 is performed using Lenze EASY Starter software version 2.0 or higher. Interfacing between a PC and the inverter is established via the EZAEAG0001 USB diagnostic adapter connected directly to the front X400 diagnostic port. Alternatively, basic parameter adjustments, state monitoring, and manual control can be handled without a computer using the EZAEBK100 plug-in keypad.
All parameter settings are stored externally on the removable L-force Memory Module E84AYM01S. This memory architecture allows complete dataset duplication across multiple drives and permits parameter sets to be transferred to a replacement unit instantly. If a drive parameter set becomes corrupted or requires initialization to a baseline state, writing value C00002 resets the inverter parameters to factory default settings.
Communication and System Integration
The Lenze E84AVSCE5512SX0 features an integrated CANopen system bus interface directly on the main control unit. This onboard interface facilitates real-time velocity commands, drive control words, cyclic status feedback, and parameterization across the machine network without requiring an optional fieldbus card.
For integration into broader automation networks, the inverter includes an expansion slot that accepts optional plug-in communication modules. Supported options include the E84AYCPM module for PROFIBUS, E84AYCER for PROFINET, E84AYCEO for EtherNet/IP, and E84AYCET for EtherCAT, allowing connection to central controllers while retaining native diagnostic and parameter capabilities.
Diagnostics and Status Indication
Status monitoring on the Lenze E84AVSCE5512SX0 is provided by four front-mounted LED indicators: DRV-READY, DRV-ERR, CAN-RUN, and CAN-ERR. These indicators give immediate visual feedback on drive execution state, fault conditions, and CANopen network status. Advanced fault inquiry can be performed by reading parameter C00160 (Current error) using EASY Starter software or via the EZAEBK100 keypad connected to the X400 port.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRV-READY | Green - Solid / Flashing | Green ON: Drive is ready for operation / active. Green flashing: Drive enabled/running. |
| DRV-ERR | Red - Solid / Flashing | Red flashing: Warning active. Red ON: Fault / Error condition active (drive inhibited). Permanently red: Internal hardware fault. |
| CAN-RUN | Green - Solid / Flashing | Green ON: CANopen Operational state. Flashing: Pre-Operational / Stopped state. |
| CAN-ERR | Red - Solid / Flashing | Red ON / Flashing: CANopen bus error / Bus off state. |
Replacement and Spare Part Considerations
When replacing an existing Lenze E84AVSCE5512SX0 frequency inverter, hardware installation requires matching the 0.55 kW rating and checking that incoming power is within 180 to 264 V AC. Parameter transfer is completed without a PC by transferring the L-force Memory Module E84AYM01S from the failed unit directly into the replacement inverter prior to powering on.
Ensure that the safety control wiring to the Safe Torque Off (STO) terminals is reconnected correctly to preserve certified SIL 3 / PL e operation. If planning system modernization or migrating away from the 8400 StateLine C series, Lenze provides a direct migration route to the Lenze i550 cabinet inverter series, specifically model i55AE155B1001000S.
Error Codes & Fault Codes
