Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVHCE5512SB0 is a cabinet-mounted frequency inverter belonging to the 8400 HighLine C model group within the 8400 HighLine family. Engineered for dynamic motion control and high-efficiency motor speed regulation in industrial automation, this unit delivers a rated power output of 0.55 kW (0.75 HP) with a continuous output current of 3 A. Operating on a single-phase supply voltage of 230 V AC with an operational window spanning 180 V AC to 264 V AC, it supplies 0 to 230 V AC to the motor across an output frequency range of 0 to 599 Hz. Built in an IP20 rated housing, the drive supports linear or square-law V/f control, sensorless vector control (SLVC), and servo control for asynchronous motors (SC-ASM) at a switching frequency of 8 kHz.
Interfacing the inverter with control hardware is handled through integrated digital and analog I/O, comprising 7 digital inputs, 2 digital outputs, 2 configurable analog inputs, and 2 analog outputs, alongside a 15-pin Sub-D feedback interface supporting HTL/TTL incremental encoders and resolvers. On-board functional safety is established via integrated Safe Torque Off (STO) hardware protection. Network communication is enabled through an integrated CANopen interface, while an extension slot accepts optional fieldbus cards such as PROFINET, PROFIBUS, EtherNet/IP, or EtherCAT. Parameter setup and commissioning are conducted using Lenze EASY Starter or L-force Engineer software via an EWWZ-USB diagnostic adapter, or directly through an XUR handheld terminal. Commissioning a replacement unit is streamlined by swapping the removable parameter memory module, and technical assistance for pre-configuring spares or parameter extraction is available through ABC Industrial Parts.
Real-time diagnostic information is displayed directly on the front panel using dedicated LED indicators and accessible through system status registers. The DRV-READY and DRV-ERROR LEDs communicate drive operating conditions, initialization states, and internal fault conditions, while CAN-RUN and CAN-ERR LEDs signal fieldbus communication states and transmission errors. Maintenance personnel can interrogate fault conditions including output short circuits, DC bus overvoltage or undervoltage, heatsink overtemperature, and encoder feedback losses using connected engineering software. First-line troubleshooting involves testing motor insulation resistance, verifying mains voltage levels, checking braking chopper circuits, and inspecting encoder cabling. When internal electronic hardware fails, component-level board servicing is not feasible on-site, making an tested exchange unit or professional repair from ABC Industrial Parts the most practical solution to restore operation.

Programming and Configuration
Engineering and commissioning of the Lenze E84AVHCE5512SB0 are executed through Lenze EASY Starter or Lenze L-force Engineer software packages. These tools allow technicians to parameterize motor parameters, define control modes, set acceleration/deceleration ramps, and configure motion control routines such as point-to-point positioning and electronic gearbox synchronization. Direct PC connectivity to the inverter is established using the Lenze USB Diagnostic Adapter EWWZ-USB, or alternatively via an XUR handheld keypad terminal for on-site parameter adjustments without a computer.
The inverter utilizes a pluggable parameter memory module that holds the complete device configuration and up to 4 independent parameter sets. This hardware feature permits simple parameter storage and backup. When replacing an inverter in the field, technicians can remove the memory module from the original drive and insert it directly into the replacement unit, transferring all configuration settings and eliminating the need for PC software tools during device swap-outs.
Communication and System Integration
The 8400 HighLine C drive includes an integrated CANopen fieldbus interface operating at transmission speeds up to 1 Mbit/s for integration into CAN-based machine networks. It provides real-time access to control words, status registers, setpoint values, and diagnostic information directly over the CAN bus.
For integration into broader industrial networks, the inverter features a dedicated option slot that accepts plug-in fieldbus communication cards. Supported option modules include E84AYCER for PROFINET, E84AYCPM for PROFIBUS-DP, E84AYCEO for EtherNet/IP, and E84AYCET for EtherCAT, allowing the drive to adapt to various PLC and controller architectures.
Diagnostics and Status Indication
System status monitoring and error identification are facilitated through four status LEDs mounted on the front panel, covering drive readiness, system faults, and CANopen network operation. Active diagnostic status words and historical error logs can be interrogated via Lenze EASY Starter, L-force Engineer, or an XUR handheld keypad terminal.
Detailed diagnostics are summarized below based on the status LED states visible on the device faceplate:
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRV-READY | Green - Solid / Flashing | Lit steady when inverter is ready for operation or running; flashing during initialization or inhibit state. |
| DRV-ERROR | Red - Solid / Flashing | Lit steady when an internal hardware fault or critical trip condition occurs; flashing code indicates specific fault category. |
| CAN-RUN | Green - Solid / Flashing | Lit steady when CANopen is in Operational state; flashing in Pre-Operational state. |
| CAN-ERR | Red - Solid / Flashing | Indicates CANopen fieldbus bus-off, frame error, or communication timeout. |
Replacement and Spare Part Considerations
When replacing a failed Lenze E84AVHCE5512SB0, ensure that the replacement hardware matches the model, power rating (0.55 kW), and supply voltage requirements (230 V AC single-phase). The removable memory module simplifies the replacement process by allowing parameter sets to be transferred to the replacement unit without connecting a laptop.
If the existing drive uses an optional fieldbus communication card (such as PROFINET E84AYCER or PROFIBUS E84AYCPM), the card must be unclipped from the donor unit and transferred to the replacement unit prior to power-up to ensure continuous network communications.
For long-term plant modernization, the Lenze i550 cabinet inverter series serves as the recommended successor family for the 8400 HighLine series, offering updated form factors and extended capabilities for modern control architectures.
