Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVBCE3714SX0XX3A34 is a 0.37 kW frequency inverter from the L-force 8400 BaseLine C series, engineered for basic single-axis speed and motion control applications. Rated for an output current of 1.3 A across an operating voltage range of 320 V to 528 V AC (nominal 400 / 480 V AC 3-phase supply), this compact drive features an IP20 enclosure designed for panel mounting inside control cabinets. Its integrated heatsink provides effective thermal management, while its motor output supports frequency control from 0 to 599 Hz with an 8 kHz switching frequency. The drive is well-suited for applications such as conveyor belts, industrial pumps, fans, and material handling systems.
For system connectivity, the inverter is equipped with an integrated CANopen fieldbus interface utilizing pluggable screw terminals for simplified cabinet integration. Control functions include V/f characteristic control (linear or square-law) and Sensorless Vector Control (SLVC), complemented by flexible I/O that includes four digital inputs, one high-speed digital frequency input capable of up to 10 kHz, one digital output, and one multi-range analog input. Commissioning a replacement unit is significantly streamlined by the pluggable E84AYM01 memory module, which holds all drive configuration data and parameters. Transferring the existing module to a replacement unit enables immediate parameter replication without requiring specialized software tools or a programming cable, though setup can also be managed using Lenze EASY Starter engineering software or the optional E84AVZKE diagnostic keypad. Assistance with configuration transfers and spare part preparation is available through ABC Industrial Parts.
Diagnostic status is continuously shown on the front panel via dedicated LEDs for DRIVE READY, DRIVE ERROR, CAN RUN, and CAN ERR. Detailed troubleshooting is supported through diagnostic parameters C00155 (error history buffer) and C00183, as well as the error logbook display on the optional E84AVZKE keypad. Fault codes such as OC1 (short circuit/earth fault), OU (DC-bus overvoltage), LU (DC-bus undervoltage), OH (heatsink overtemperature), CE0 (CAN communication error), and P01 (memory module error) help pinpoint operational issues on the motor side, supply lines, or fieldbus. When internal hardware errors like fault H05 occur on control components, field servicing is not possible, making drive replacement or a tested exchange unit from ABC Industrial Parts the standard resolution.

Programming and Configuration
Parameterization of the Lenze E84AVBCE3714SX0XX3A34 frequency inverter can be performed using Lenze EASY Starter engineering software or directly on the unit using the optional E84AVZKE diagnosis keypad. EASY Starter provides online monitoring, parameter editing, and offline project creation, while the keypad provides direct access to parameter structures and the active fault logbook.
Parameter retention and backup rely on the pluggable E84AYM01 memory module. All operational parameters, ramp settings, motor data, and I/O configurations reside directly on this module, allowing complete parameter sets to be duplicated across multiple units or restored after a hardware swap without connection to a PC.
Communication and System Integration
The L-force 8400 BaseLine C drive incorporates an integrated CANopen system bus interface using pluggable terminals, reducing wiring complexity within the control cabinet. The CANopen interface allows centralized control, parameter transfer, and real-time status feedback across automation networks.
Proper network integration requires setting valid node addresses and matching baud rates across the network. The fieldbus segment requires standard 120 Ohm termination resistors at both network ends to prevent signal reflections, while CAN RUN and CAN ERR status LEDs monitor fieldbus operational states and bus-off conditions.
Diagnostics and Status Indication
Front-panel status indicators provide real-time visual monitoring for operational state and fieldbus health. Green and red LEDs clearly indicate whether the drive is operational, experiencing a fault, or encountering CANopen communication issues.
Extended diagnostic evaluation is available through diagnostic parameters C00155 (error history buffer) and C00183, accessible via EASY Starter software or the E84AVZKE keypad logbook display to review active faults and historical trip codes.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE READY | Green - Solid/Flashing | Indicates normal drive operation and readiness |
| DRIVE ERROR | Red - Solid/Flashing | Indicates drive fault or warning condition |
| CAN RUN | Green - Solid/Flashing | Indicates CANopen operational network state |
| CAN ERR | Red - Solid/Flashing | Indicates CANopen fieldbus communication fault |
Replacement and Spare Part Considerations
When replacing an E84AVBCE3714SX0XX3A34 inverter, ensure that the replacement unit matches the exact part number and power rating (0.37 kW, 1.3 A output). Moving the pluggable E84AYM01 memory module from the original drive to the replacement drive transfers all parameters instantly without re-commissioning.
Verify that power supply connections (320-528 V AC), motor wiring, CANopen bus lines, and I/O terminal connections are correctly landed. For long-term migration planning, the Lenze i500 series (including i550 inverters) serves as the modern successor family for the discontinued 8400 BaseLine series.
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 / Earth Fault | Short circuit or earth fault detected on motor terminals U, V, W. | Short circuit in motor cable; earth fault in motor winding; acceleration time set too short. | Check motor and motor wiring for short circuits and insulation resistance; check acceleration ramp setting. |
