Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVSCE3034VX0 is a 30 kW frequency inverter within the Lenze 8400 StateLine C series, engineered to deliver dynamic motor control in demanding industrial automation applications. Operating on a 3-phase supply voltage range of 320 V AC to 550 V AC, this unit provides a rated output current of 59 A and an adjustable output frequency from 0 Hz to 599 Hz at a switching frequency of 4 kHz. The drive supports versatile motor control algorithms, including V/f characteristic control, sensorless vector control, and servo modes. Designed for surface or panel mounting, it provides continuous torque regulation and precision speed control for high-torque conveyor lines, material handling systems, industrial pumps, ventilation fans, and packaging machinery.
Field integration and parameter administration on the E84AVSCE3034VX0 are built for flexible machine connectivity and rapid maintenance. Standard control interfaces include 8 digital inputs, 4 digital outputs, 2 analog inputs, and 2 analog outputs, complemented by an onboard CANopen system bus interface operating at speeds up to 1000 kbps. Expansion slots accommodate optional communication modules, including PROFINET (E84AYCER), PROFIBUS (E84AYCPM), EtherCAT (E84AYCEC), and EtherNet/IP. Commissioning and parameter backup are performed using Lenze L-force Engineer software, an optional XT Keypad (E84DDFXP), or a USB diagnostic adapter via the X6 diagnostic port. When swapping out a unit, the pluggable E84AYM memory module allows a complete parameter set to be transferred directly to the replacement inverter without using a PC or software, with technical support available through ABC Industrial Parts.
System health and operational states are displayed locally via multi-color LED indicators for drive status and CAN bus communication. Diagnostics are supported by an internal fault history buffer that stores the last 8 fault events with timestamps, accessible through the XT Keypad text display or the L-force Engineer online diagnostic panel with its real-time oscilloscope function. First-line troubleshooting for trip events should include checking mains power stability, verifying motor insulation resistance, inspecting output wiring at terminals U, V, and W, and clearing heatsink cooling fins. When internal microcode execution or hardware execution errors occur, such as fault code 0x00C1, internal board failure cannot be serviced in the field; supplying a fully tested replacement drive or initiating a unit repair through ABC Industrial Parts offers the most reliable route to restoring machine uptime.

Programming and Configuration
The Lenze E84AVSCE3034VX0 frequency inverter is configured using the Lenze L-force Engineer commissioning software suite. The software provides tools for drive parameterization, live signal monitoring, motor auto-tuning, and offline project creation. Local parameter adjustments and status checks can also be performed without a PC by attaching an optional Lenze E84DDFXP XT Keypad to the X6 diagnostic interface, or by using a USB diagnostic adapter.
Parameter retention and drive cloning are streamlined by the pluggable Lenze E84AYM memory module. All operational parameters, motor profiles, and application settings reside directly on this removable chip. When replacement or maintenance is required, transferring the memory module to a donor unit imports the exact drive configuration, enabling immediate startup without requiring software downloads or network re-addressing.
Communication and System Integration
Integration into industrial control networks is managed through an integrated CANopen system bus interface capable of communication speeds up to 1000 kbps. The onboard CANopen interface supports process data objects (PDO) for dynamic motion control and service data objects (SDO) for parameter exchange and drive diagnostics across higher-level PLC architectures.
To support broader control environments, the E84AVSCE3034VX0 features pluggable expansion module slots. Optional communication cards—including the E84AYCER for PROFINET, E84AYCPM for PROFIBUS DP, E84AYCEC for EtherCAT, and EtherNet/IP options—allow the inverter to integrate into distributed fieldbus networks. Additional hardware control is facilitated via onboard I/O comprising 8 digital inputs, 4 digital outputs, 2 configurable analog inputs, and 2 analog outputs.
Diagnostics and Status Indication
Real-time operational feedback on the E84AVSCE3034VX0 is provided through multi-color LED indicators located on the drive front panel, giving immediate state indications for power, inverter operation, and CAN bus health. Detailed diagnostic data is accessible using the Lenze L-force Engineer software platform, which includes an online diagnostic panel and a real-time oscilloscope tool for analyzing signal traces.
Fault management relies on an internal fault history buffer that logs the last 8 alarm and error events with corresponding timestamps. Maintenance technicians can inspect the event log directly via the XT Keypad screen or over CANopen SDO objects. Active trip conditions trigger protective trips to shield the power electronics and connected motor.
Status LED Indicators

|---|---|---|
| DRIVE SET | Green / Red - Solid / Flashing / Off | Green ON: Inverter operational / ready; Green flashing: Operation enabled / active output; Red ON: Active fault condition; Off: No supply power. |
| CAN RUN | Green - Solid / Flashing / Off | Green ON: CANopen state Operational; Green flashing: Pre-Operational; Single flash: Stopped; Off: Bus inactive or disabled. |
| CAN ERR | Red - Solid / Flashing | Red ON: Bus off / Serious CAN bus error; Flashing: Warning condition / Error counter limit exceeded. |
Replacement and Spare Part Considerations
When swapping a Lenze E84AVSCE3034VX0 drive, physical and electrical ratings must be verified before commissioning. Ensure the replacement inverter matches the required 30 kW power rating, 59 A rated current, and 320–550 V AC supply range. If the original installation utilizes fieldbus modules such as the E84AYCER (PROFINET) or E84AYCPM (PROFIBUS), these cards must be unclipped from the failed unit and transferred to the replacement module to preserve network architecture.
Parameter management during drive replacement is simple when utilizing the E84AYM memory module. Removing the memory card from the non-functional drive and inserting it into the replacement inverter transfers all stored parameters, motor setups, and custom configuration settings automatically. This eliminates the need to perform PC software re-commissioning or manual parameter entry during field service.
While the Lenze 8400 StateLine series is in phase-out status in favor of the Lenze i550 cabinet drive series, maintaining direct E84AVSCE3034VX0 replacement units allows existing panel layouts and wiring topographies to remain unchanged without requiring software migration or re-engineering.

Frequently Asked Questions
How do I transfer drive settings to a replacement Lenze E84AVSCE3034VX0?
Settings can be transferred by moving the pluggable E84AYM memory module from the original drive to the replacement unit. This transfers all configuration parameters automatically without requiring a PC or engineering software.
What fieldbus communications are supported on the E84AVSCE3034VX0?
The drive features built-in CANopen system bus communication operating up to 1000 kbps. Additional protocols including PROFINET (E84AYCER), PROFIBUS DP (E84AYCPM), EtherCAT (E84AYCEC), and EtherNet/IP can be supported by inserting the corresponding extension module into the option slot.
Which commissioning tools can be used with this frequency inverter?
The inverter can be commissioned using Lenze L-force Engineer software on a PC, an optional Lenze E84DDFXP XT Keypad connected to the X6 diagnostic port, or a USB diagnostic adapter.
How do I clear or diagnose internal system error fault code 0x00C1?
Fault code 0x00C1 indicates an internal hardware error or microcode execution fault. First power-cycle the drive; if the error persists, the internal main board has failed, and the drive must be repaired or replaced.
What do the DRIVE SET LED colors indicate on the front panel?
A solid green DRIVE SET LED indicates the inverter is operational and ready; flashing green indicates operation is enabled with active output; solid red signals an active fault condition; and an unlit LED indicates no control supply power.
