Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVHCE7514SX0 is a 0.75 kW cabinet-mounted frequency inverter within the 8400 HighLine C series and Inverter 8400 family. Operating on a 3-phase supply voltage from 320 V to 528 V AC with a rated mains current of 3.2 A, this compact drive delivers a continuous output current of 2.4 A and an output frequency range of 0 to 599 Hz at an 8 kHz switching frequency. Engineered for precision speed, torque, and positioning control in packaging machinery, material handling, textile manufacturing, and automotive assembly, the unit supports Linear V/f, Square-law V/f, Sensorless Vector Control, and Servo Control modes. Physical interface features include 8 digital inputs, 4 digital outputs, 2 analog inputs, 2 analog outputs, and hardware-integrated dual-channel Safe Torque Off (STO) functional safety.
Network integration and hardware interfacing are provided via an onboard CANopen system bus alongside a modular MCI cassette slot that accepts option cards for PROFINET (E84AYCER), PROFIBUS (E84AYCPM), EtherCAT (E84AYCEC), and EtherNet/IP (E84AYCEO). Commissioning and parameter management are performed using software tools such as EASY Starter or L-force Engineer, or physically via the Keypad XT display (E84AYKPT) and USB Diagnostic Adapter (E84AYCCA). The unit features a pluggable EASY Memory Module (E84AYM200) that stores all device parameters and firmware alignments. Swapping this memory module directly into a replacement unit enables tool-free parameter restoration during hardware servicing, avoiding the need for on-site software programming tools. ABC Industrial Parts supports maintenance teams by supplying replacement drives, memory modules, and compatible expansion options.
Status monitoring and diagnostic feedback are provided via four front-panel LED indicators (DRIVE READY, DRIVE ERROR, CAN RUN, CAN ERR), keypad display readouts, and online diagnostic objects in EASY Starter. Common system interruptions, such as overvoltage (OU), undervoltage (LU), earth faults (OC2), or fieldbus timeouts (CE0/CE1), can be resolved using standard site checks on supply lines, braking resistors, and network cabling. If the DRIVE ERROR LED remains solid red upon initial power-up or an internal fault code (PINT) is registered, an internal control board or power section failure is indicated. Because internal hardware faults cannot be serviced in the field, replacing the inverter or choosing a tested exchange unit from ABC Industrial Parts provides the fastest path to restoring production.

Programming and Configuration
The Lenze E84AVHCE7514SX0 inverter uses the Lenze EASY Engineering toolset, including EASY Starter and L-force Engineer, for configuration, tuning, and diagnostic tasks. PC connectivity is established through the USB Diagnostic Adapter (E84AYCCA) attached to the diagnostic interface, or remotely over a configured fieldbus network.
Parameter sets, motor calibration data, and application profiles reside on the pluggable EASY Memory Module (E84AYM200). During initial installation, configurations can be uploaded from software or restored directly from a backup. Local parameter adjustments, manual motor control, and operational monitoring can also be executed directly at the cabinet using the pluggable Keypad XT (E84AYKPT) display accessory.
Communication and System Integration
An onboard CANopen system bus interface is integrated directly into the control connection block, facilitating control, parameterization, and state monitoring without requiring additional options. Dedicated CAN RUN and CAN ERR LEDs on the front panel provide network status tracking.
For integration into major fieldbus networks, the drive features a modular MCI option slot that accepts pluggable communication cassettes. Supported MCI cards include PROFINET (E84AYCER), PROFIBUS (E84AYCPM), EtherCAT (E84AYCEC), and EtherNet/IP (E84AYCEO), enabling direct connectivity to centralized PLCs and plant network infrastructure.
Diagnostics and Status Indication
Visual status indication on the front panel of the E84AVHCE7514SX0 consists of four LEDs indicating drive operational status and fieldbus connectivity. The DRIVE READY and DRIVE ERROR LEDs show operational state, active warnings, and trip conditions, while the CAN RUN and CAN ERR LEDs monitor CANopen bus traffic and fault states.
Comprehensive diagnostic routines, real-time message tracking, and fault history logs can be accessed using the Keypad XT module or by connecting EASY Starter online via the USB Diagnostic Adapter (E84AYCCA). CANopen status objects also allow full diagnostic monitoring across the fieldbus network.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE READY | Green - Off / Flashing / Solid Green | Off: No supply voltage or initialization active. Flashing: Drive ready / inhibited. Solid Green: Drive operational / running. |
| DRIVE ERROR | Red - Off / Flashing / Solid Red | Off: Normal operation, no fault active. Flashing: Warning active. Solid Red: Trip / Fault active (drive disabled). If solid red persists immediately upon power up, indicates internal hardware failure. |
| CAN RUN | Green - Off / Flashing / Solid Green | Indicates CANopen network communication status (Off = stopped, Flashing = pre-operational, Solid Green = operational). |
| CAN ERR | Red - Off / Flashing / Solid Red | Indicates CANopen bus error / bus-off status. |
Replacement and Spare Part Considerations
To swap a Lenze E84AVHCE7514SX0 inverter efficiently, transfer the pluggable EASY Memory Module (E84AYM200) from the existing unit to the replacement drive. The memory module transfers all drive settings and parameter structures upon power-up without requiring software tools on-site.
Ensure that any installed MCI fieldbus module (such as PROFINET E84AYCER or PROFIBUS E84AYCPM) is transferred to the new drive's MCI cassette slot. Confirm that hardware settings, node addresses, and safety terminal connections match the original installation layout.
For long-term hardware planning during lifecycle transitions, the Lenze i550 Cabinet Inverter (model number i55AE275F01000000S) is designated as the recommended successor unit for new system designs and control cabinet updates.

Frequently Asked Questions
How are parameters transferred to a replacement Lenze E84AVHCE7514SX0 drive?
Parameter transfer is performed tool-free by swapping the pluggable EASY Memory Module (E84AYM200) from the old inverter into the replacement unit. Alternatively, parameter sets can be loaded using EASY Starter software via the USB Diagnostic Adapter (E84AYCCA) or programmed using the Keypad XT module.
Which fieldbus interfaces are available for the E84AVHCE7514SX0?
The inverter includes built-in CANopen communication terminals. It can also be integrated into PROFINET, PROFIBUS, EtherCAT, or EtherNet/IP networks by installing the corresponding optional MCI expansion module into the MCI cassette slot.
What does a solid red DRIVE ERROR LED indicate on startup?
A solid red DRIVE ERROR LED immediately upon power-up indicates an active fault condition or an internal hardware failure. If power cycling does not clear the error, or if fault code PINT is logged, internal hardware components are damaged and the unit must be repaired or replaced.
Does the E84AVHCE7514SX0 drive include integrated safety functions?
Yes, the drive is equipped with dual-channel Safe Torque Off (STO) functional safety terminals, satisfying modern safety standard requirements without requiring external mains contactors.
What is the recommended successor model for the Lenze 8400 HighLine 0.75kW drive?
The recommended successor model for migration and new cabinet designs is the Lenze i550 Cabinet Inverter, specifically model number i55AE275F01000000S.
