Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVBDE7514SX0XX2C34 is a compact 0.75 kW frequency inverter from the 8400 Baseline D model series within the 8400 Baseline product family. Engineered for panel mounting inside control cabinets with an IP20 protection rating, this AC drive operates on a 3-phase supply voltage rating of 400/480 V AC across an allowable input voltage range of 320 V to 528 V AC with a rated current of 2.4 A. The inverter provides reliable speed regulation and dynamic torque control for three-phase AC motors over an output frequency range of 0 to 599 Hz, utilizing either sensorless vector control or linear/square-law V/f control modes.
For control and fieldbus integration, the unit features an integrated CANopen system bus interface supporting data transmission rates up to 1 Mbit/s, alongside onboard I/O comprising 4 digital inputs (24 V DC), 1 open-collector digital output, 1 selectable analog input (0-10 V or 0/4-20 mA), and 1 analog output (0-10 V). It also incorporates built-in Safe Torque Off (STO) functional safety. Commissioning a replacement unit is streamlined by Lenze pluggable memory module technology, which houses all drive parameter configurations on a removable chip for tool-free transfer into a replacement chassis. System configuration and parameter adjustments can also be managed using L-force EASY Starter software connected via the X6 diagnostic port using a Lenze USB System Bus Adapter EWW0006 or directly with a Lenze Keypad X400. ABC Industrial Parts can assist maintenance teams with parameter extractions and replacement unit supply to minimize downtime.
Diagnostic status is immediately visible through front-panel LED indicators, including a green DRIVE READY LED and a red DRIVE ERROR LED. A solid green light indicates normal operation, whereas a flashing green light shows the drive is disabled or suppressed. Active warnings or active fault states with drive inhibition are signaled by a red LED, while a rapidly flashing red light points to an internal hardware fault. Additional diagnostic logs and historical fault records are retained in non-volatile memory and accessible via parameter diagnostic registers such as error memory C00150. When hardware faults occur, internal board-level components are not field-serviceable, making a fully tested replacement drive from ABC Industrial Parts the most reliable route back to production.

Programming and Configuration
Parameter management and drive commissioning for the Lenze 8400 Baseline series can be performed using the L-force EASY Starter engineering software. Connecting a PC to the drive's X6 diagnostic interface requires the Lenze USB System Bus Adapter EWW0006. Alternatively, local parameter editing and operation can be carried out using the pluggable Lenze Keypad X400 attached directly to the front interface.
The E84AVBDE7514SX0XX2C34 utilizes a pluggable memory module that stores the complete drive configuration, including motor data, I/O mapping, and CANopen network parameters. When replacing a failed unit, swapping the memory chip from the old unit into the spare hardware transfers all operational parameters instantly without requiring software connections or re-commissioning steps.
Communication and System Integration
The Lenze E84AVBDE7514SX0XX2C34 comes standard with an onboard CANopen system bus interface. Supporting communication speeds up to 1 Mbit/s, this integrated fieldbus connection enables direct control, speed reference transmission, and status monitoring from central PLCs without requiring external communication option modules.
In addition to fieldbus networking, the drive provides physical I/O terminals for hardwired control. The interface includes 4 digital inputs operating at 24 V DC, 1 open-collector digital output, 1 analog input configurable for 0-10 V or 0/4-20 mA signals, and 1 analog output (0-10 V). Integrated Safe Torque Off (STO) functional safety allows safety circuits to disable drive torque directly without installing external main contactors.
Diagnostics and Status Indication
Status monitoring on the E84AVBDE7514SX0XX2C34 is provided through front-panel LED indicators and internal diagnostic registers. The green DRIVE READY LED and red DRIVE ERROR LED give immediate operational feedback. Historical trip data and current fault conditions are stored in non-volatile memory and can be examined through parameter register C00150 (error memory) via software or the Keypad X400.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE READY (Green LED) | Green - Solid / Flashing | Green ON = Drive in operation / ready for operation. Green flashing = Drive disabled or suppressed. |
| DRIVE ERROR (Red LED) | Red - Solid / Flashing | Red flashing = Warning active. Red ON = Fault active (drive inhibited). Fast red flashing = Hardware fault or critical system fault requiring device replacement/repair. |
Replacement and Spare Part Considerations
When selecting a replacement frequency inverter, verify that the complete part number matches E84AVBDE7514SX0XX2C34 to guarantee identical power ratings (0.75 kW), voltage specifications (3AC 400/480 V), and integrated CANopen hardware.
The Lenze 8400 Baseline series has been discontinued by the manufacturer, with the Lenze i510 and i550 series recommended as modern replacement families for new machine designs. However, for existing panel installations, replacing a failed unit with an exact E84AVBDE7514SX0XX2C34 drive ensures drop-in physical compatibility and avoids control cabinet re-engineering or PLC software modifications.
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 / Overcurrent | Short circuit or excessive output current detected at drive output during acceleration. | Short circuit on motor terminals, motor cable capacitance too high, ground fault, acceleration time set too short. | Check motor wiring for short circuits/ground faults, check motor insulation, increase acceleration time setting. |
| OC2 | Overcurrent during deceleration | Excessive motor current detected during braking/deceleration. | Deceleration time too short, brake chopper defective or braking resistor missing. | Increase deceleration time, verify brake chopper/resistor setup. |
| OU | Mains Overvoltage | DC bus voltage exceeds maximum allowed upper limit threshold. | Mains supply voltage too high, generatoric energy during deceleration exceeds limits without braking resistor. | Check mains voltage supply, increase deceleration time or fit external braking resistor. |

Frequently Asked Questions
How do I transfer parameter settings to a replacement Lenze E84AVBDE7514SX0XX2C34 drive?
Parameters can be transferred without a computer by moving the pluggable memory module from the original drive into the replacement unit. Alternatively, parameters can be uploaded and downloaded using L-force EASY Starter software via a Lenze USB System Bus Adapter EWW0006 or manually entered using the Lenze Keypad X400.
What does a fast red flashing LED indicate on the drive front panel?
A fast red flashing DRIVE ERROR LED indicates a critical hardware fault or internal system fault. If this condition persists after cycling input power and verifying external wiring, the drive requires service or unit replacement.
