Lenze E84AVSCE5514SB0 8400 StateLine C Frequency Inverter
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVSCE5514SB0 is a 0.55 kW frequency inverter belonging to the L-force 8400 StateLine C series, engineered for IP20 control cabinet installation. Operating on a 3-phase supply range of 320 to 528 V AC (400/480 V AC nominal), this drive delivers a rated output current of 1.8 A with a maximum current of 2.7 A and an output frequency range of 0 to 599 Hz. It supports both linear or square V/f characteristic curves and Sensorless Vector Control (SLVC) for flexible motor management in material handling, packaging machinery, textile manufacturing, and HVAC applications. Designed with an integrated Class C2 RFI/EMC filter and Safe Torque Off (STO) functional safety, the drive provides reliable motor control without requiring external line filters or safety contactors.
Connecting the drive into an industrial automation architecture relies on built-in control terminals and communication interfaces. The hardware provides 5 digital inputs, 1 digital output, 1 analog input, 1 analog output, and 1 relay output, alongside an onboard CANopen system bus. Fieldbus network integration can be expanded using optional modules such as the E84AYCPM PROFINET, E84AYCPV PROFIBUS, or E84AYCET EtherCAT communication cards. Putting a replacement drive into service is simplified by the pluggable E84AYM memory module series, which stores complete device parameters and allows hot-swappable, zero-tool configuration transfers from an existing unit. Parameters can also be configured or modified using the optional Keypad X400 (E84AVZKE000) or via the L-force Engineer software using the USB Diagnostic Adapter (E84AYCER). ABC Industrial Parts provides support for sourcing replacement drives and compatible memory options to maintain full machine functionality.
System monitoring and fault evaluation on the E84AVSCE5514SB0 are managed through two multi-color status LEDs labeled DRIVE and CAN, plain-text error messages on the optional X400 keypad, or software diagnostic workspaces. Internal error parameters such as C00183 record current fault conditions while C00150 maintains a historical fault log. First-line troubleshooting for standard alerts—such as DC-bus overvoltage (0x00110020), DC-bus undervoltage (0x00110030), or power stage overcurrent (0x00110050)—involves inspecting main power supply lines, motor wiring insulation, deceleration ramp settings, and external braking circuits. If a critical internal system fault (0x00110010) occurs due to board-level component failure, field servicing is generally not viable, and exchanging the unit through ABC Industrial Parts offers a fast path to restoring operations.

Programming and Configuration
Configuring the Lenze E84AVSCE5514SB0 frequency inverter is handled through Lenze's L-force Engineer software environment or directly on the unit via the optional X400 keypad (part number E84AVZKE000). Connection to a PC running L-force Engineer is established using the USB Diagnostic Adapter (E84AYCER), which provides direct access to the parameter structure, motor control profiles (V/f characteristic or Sensorless Vector Control), and safety functionality settings.
A central feature of the 8400 StateLine architecture is the removable E84AYM series Memory Module. All operational parameters, network settings, and drive configurations reside directly on this card. When replacing a damaged inverter, maintenance personnel can transfer the existing memory module into the replacement unit without needing engineering software, cables, or laptop connections.
Communication and System Integration
The E84AVSCE5514SB0 features a built-in CANopen system bus interface as standard, enabling motion control and status data exchange across CANopen networks. The drive supports flexible integration into broader automation networks via dedicated extension slots designed for optional fieldbus communication modules.
Available extension modules include the E84AYCPM PROFINET module, E84AYCPV PROFIBUS module, and E84AYCET EtherCAT module. In addition to network interfaces, the inverter includes physical control terminals consisting of 5 digital inputs, 1 digital output, 1 analog input, 1 analog output, and 1 relay output for direct hardwired control signals.
Diagnostics and Status Indication
The drive provides dual status LEDs on the front panel for immediate visual diagnostics. The DRIVE LED uses green and red states (solid or flashing) to indicate operational readiness, active warnings, or fault conditions. The CAN LED uses green and red states to show the communication status and fault conditions of the onboard CANopen system bus.
Detailed diagnostic analysis is available using parameter C00183 for the active error code and parameter C00150 for the historical error log buffer. These parameters can be queried via the X400 keypad, L-force Engineer software over USB diagnostic adapter E84AYCER, or over the active fieldbus network.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE | Green/Red - Solid / Flashing | Indicates drive operational state, warning, or error condition |
| CAN | Green/Red - Solid / Flashing | Indicates CANopen system bus communication status and fault conditions |
Replacement and Spare Part Considerations
When replacing an existing Lenze E84AVSCE5514SB0 inverter, it is critical to confirm that the replacement matches the 0.55 kW power rating, 1.8 A nominal output current, and 400/480 V AC supply requirements. Using the pluggable E84AYM memory module allows immediate transfer of all parameter settings to the new hardware.
Ensure that any installed fieldbus extension modules (such as PROFINET, PROFIBUS, or EtherCAT cards) are transferred to the replacement drive along with the memory module. While the 8400 StateLine series is in its phase-out phase, the recommended long-term successor is the Lenze i550 cabinet inverter series (model i55AE255F1AV00000S), which requires parameter conversion during complete system upgrades.

Frequently Asked Questions
How do I transfer parameters to a replacement Lenze E84AVSCE5514SB0 inverter?
Parameter transfer can be accomplished by swapping the pluggable E84AYM series memory module from the original drive into the replacement unit. Alternatively, parameter sets can be uploaded and downloaded using L-force Engineer software with the E84AYCER USB diagnostic adapter or via the X400 keypad.
What diagnostic software is used with the Lenze 8400 StateLine C drive?
Diagnostic monitoring and parameter setting are supported by Lenze L-force Engineer software connected via the USB Diagnostic Adapter (E84AYCER). Drive status and active errors can also be read directly via parameters C00183 and C00150 on the optional X400 keypad.
Which fieldbus extension modules are compatible with the E84AVSCE5514SB0?
While the drive includes native onboard CANopen communication, optional extension modules can be installed, including the E84AYCPM PROFINET module, E84AYCPV PROFIBUS module, and E84AYCET EtherCAT module.
What does fault code 0x00110010 indicate on this drive?
Fault code 0x00110010 signifies an internal system or hardware fault detected during self-testing. If power cycling the inverter does not clear the error, the internal controller board or memory is defective and requires repair or replacement.
What functional safety features are built into the Lenze E84AVSCE5514SB0?
The E84AVSCE5514SB0 features integrated Safe Torque Off (STO) functional safety, which allows safety-related torque disabling without needing external safety contactors in the motor lines.
What is the recommended modern replacement for the Lenze 8400 StateLine E84AVSCE5514SB0 drive?
The recommended successor for the 8400 StateLine series is the Lenze i550 cabinet inverter series, specifically model i55AE255F1AV00000S for 0.55 kW applications.
