Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVTCE1524SB0 is a 1.5 kW frequency inverter from the 8400 TopLine C series within the Inverter Drives 8400 family. Built for control cabinet installation with an IP20 protection rating, this compact drive operates on a 3-phase AC supply ranging from 320 to 528 V AC (rated at 400 V / 480 V AC) and provides a rated output current of 3.9 A at 400 V and 3.2 A at 480 V. It is engineered for dynamic multi-axis motion control, electronic gearing, registration mark control, and winding applications. The unit supports versatile control modes including open-loop V/f, sensorless vector control, and closed-loop servo control with encoder feedback, alongside integrated Safe Torque Off (STO) functional safety.
Field connection and system interfacing are facilitated by 8 programmable digital inputs, 4 digital outputs, dual bipolar analog I/O channels, and an integrated CANopen system bus. Connectivity can be extended through the Module Communication Interface (MCI) slot using optional modules for PROFINET (E84AYCER), EtherCAT (E84AYCET), PROFIBUS (E84AYCPM), or EtherNet/IP (E84AYCEO). Commissioning and parameter adjustments are handled via Lenze L-force Engineer or EASY Starter software connected using the E84DWFE USB adapter, or locally via the E84DDFE keypad. All drive parameters reside on a pluggable Lenze E84AYM memory module, allowing rapid configuration swapping during replacements without a PC. Technical support from ABC Industrial Parts can assist maintenance teams with parameter transfers and replacement verification.
Operational status and diagnostics are provided via front-panel LED indicators (DRIVE RDY, DRIVE ERR, CAN RUN, CAN ERR), a diagnostic history log, and diagnostic software views. Fault codes such as OC1 (short circuit), OC5 (thermal overload), OU (DC bus overvoltage), LU (DC bus undervoltage), and OH (heatsink overtemperature) pinpoint external electrical, mechanical, or thermal issues. If code H01 appears, it signals an internal microcontroller or hardware initialization fault that cannot be repaired in the field. In the event of internal hardware failure, sourcing a tested replacement drive or using repair options through ABC Industrial Parts provides a fast path to restoring production.

Programming and Configuration
Engineering and commissioning for the Lenze E84AVTCE1524SB0 frequency inverter are supported by the Lenze L-force Engineer software suite and the Lenze EASY Starter commissioning program. These software environments enable online diagnostics, drive parameter editing, motion profile adjustments, and live oscilloscope signal monitoring. A direct PC link is established using the USB Adapter E84DWFE, while local manual parameter entry can be executed on the machine via the pluggable Keypad E84DDFE display unit.
Parameter retention is managed electronically using the Lenze Memory Module E84AYM series. This removable EEPROM card stores the full drive configuration, motor parameter data, and application settings. During component replacement, the memory module can be moved directly into the donor unit, enabling zero-software drive replacement on the shop floor. Transferring a parameter set from an incompatible hardware revision or series will trigger fault code P13, which requires parameter set validation or default parameter restoration using L-force Engineer.
Communication and System Integration
Network connectivity on the Lenze E84AVTCE1524SB0 is anchored by an integrated CANopen system bus capable of transmission speeds up to 1000 kbit/s. The CANopen interface provides real-time drive-to-drive communication for multi-axis synchronization, positioning registers, and electronic shafting across complex production lines. Bus state monitoring conforms to CiA 303-3 specifications via dedicated CAN status LEDs.
To interface with higher-level industrial network architectures, the drive incorporates a Module Communication Interface (MCI) slot. This interface accepts option cards for broader fieldbus integration, including E84AYCER (PROFINET), E84AYCET (EtherCAT), E84AYCPM (PROFIBUS), and E84AYCEO (EtherNet/IP). Bus errors on the primary system bus are flagged as fault CE0, while loss of communication between the inverter control board and the MCI module reports as fault CE4.
Diagnostics and Status Indication
Diagnostic assessment of the E84AVTCE1524SB0 drive is conducted through multiple physical and software channels. Four status LEDs located on the control front panel indicate real-time operation and fieldbus communication conditions. Advanced diagnostic data can be viewed via the diagnostic history log memory buffer, keypad text displays, or online diagnostic functions in L-force Engineer and EASY Starter software.
The status LEDs provide immediate feedback regarding drive power, fault states, and CANopen network integrity. The table below outlines the specific LED states and their operational meanings:
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRIVE RDY | Green - Solid / Blinking | Green steady: Inverter ready for operation. Green blinking: Inverter operational / running. |
| DRIVE ERR | Red - Solid / Blinking | Red blinking: Warning active. Red steady: Fault active or internal control board failure. |
| CAN RUN | Green - Solid / Blinking | Indicates CANopen operational, pre-operational, or stopped state according to CiA 303-3. |
| CAN ERR | Red - Solid / Blinking | Indicates CANopen bus error or bus-off status. |
Replacement and Spare Part Considerations
Before replacing an existing drive with a new Lenze E84AVTCE1524SB0, verify that the 1.5 kW power rating and 3-phase 400/480 V AC voltage specification match the existing system setup. Ensure that all terminal connections for the 8 digital inputs, 4 digital outputs, and 2 analog I/O channels are correctly wired and that any installed MCI communication card (PROFINET, EtherCAT, PROFIBUS, or EtherNet/IP) is transferred and properly seated into the extension slot.
System downtime during replacement is significantly minimized by swapping the Lenze E84AYM memory module from the damaged unit directly into the replacement inverter. Because the memory module stores the complete operating configuration, the spare drive boots with identical parameters without requiring programming software. Following power-up, confirm proper operation by observing the DRIVE RDY and fieldbus LED status indicators.

Frequently Asked Questions
What engineering software is required to configure the Lenze E84AVTCE1524SB0?
The drive is configured and commissioned using either the Lenze L-force Engineer software suite or Lenze EASY Starter. Connection to a PC requires a USB Adapter E84DWFE, or parameters can be adjusted directly using the pluggable Keypad E84DDFE.
How do I transfer drive parameters to a replacement E84AVTCE1524SB0 drive?
Drive parameters are stored on a pluggable Lenze E84AYM memory module. You can transfer parameters by removing the memory card from the faulty drive and inserting it into the replacement inverter prior to powering on.
Which fieldbus networks does the 8400 TopLine C inverter support?
The drive features an integrated CANopen system bus (up to 1000 kbit/s). Additional protocols can be added using the MCI slot, including PROFINET (E84AYCER), EtherCAT (E84AYCET), PROFIBUS (E84AYCPM), and EtherNet/IP (E84AYCEO).
What should I do if the drive displays fault code H01?
Fault code H01 indicates an internal hardware or microcontroller initialization failure. Power cycle the drive; if the fault persists, the internal board failure is non-field serviceable and requires inverter replacement or repair.
Does the Lenze E84AVTCE1524SB0 include integrated safety functions?
Yes, the inverter includes integrated Safe Torque Off (STO) functional safety built directly into the hardware, eliminating the need for external safety contactors.
