Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVSCE1522SX0 is a panel-mounted 1.5 kW frequency inverter belonging to the 8400 StateLine C series within the Lenze Inverter Drives 8400 family. Operating across a line input voltage range of 180 V to 264 V AC on single-phase or three-phase 230 V networks, this compact drive provides dynamic speed and torque regulation for three-phase AC asynchronous motors. Supporting standard V/f characteristic control and Sensorless Vector Control (SLVC), the unit delivers controlled motion up to an output frequency of 599 Hz with a continuous output current rating of 7 A at an 8 kHz switching frequency. Functional safety is directly integrated into the unit through Safe Torque Off (STO), certified to EN ISO 13849-1 (PL e) and EN 62061 / IEC 61508 (SIL 3) standards to minimize external electromechanical safety hardware.
For physical control and signal interface, the drive features five 24 V DC digital logic inputs, one digital output, a 12-bit configurable analog input (supporting 0–10 V, ±10 V, or 0/4–20 mA), and a 0–10 V analog output. Network connectivity is established natively through an onboard CANopen system interface operating at baud rates up to 1000 kbit/s, along with an MCI extension slot that accommodates optional communication cards such as PROFIBUS (E84AYCPM), PROFINET (E84AYCER), or EtherCAT (E84AYCET). Commissioning or replacing an active unit is simplified by a pluggable EEPROM memory chip containing the complete drive parameter set, allowing rapid hardware swaps without software tools. ABC Industrial Parts can support maintenance teams with tested replacement hardware and compatible system components to keep production equipment running.
Diagnostic monitoring is facilitated by front-mounted status LEDs including DRIVE RDY, DRIVE ERROR, CAN RUN, and CAN ERR, which provide instantaneous status checks for inverter operation and fieldbus activity. Detailed parameter extraction, runtime values, and error memory buffers are accessible via parameters C00150, C00009, and C00160 using the Keypad X400 (E84DDFXP000) or Lenze L-force Engineer software version 2.6 or higher. Common operational trips like DC bus overvoltage (code 0x00230001), motor phase failure (code 0x00240001), or memory module issues (code 0x00510001) can often be addressed through wiring checks, ramp time adjustments, or memory module re-seating. Persistent hardware faults such as power section failures (code 0x00250001) indicate board-level damage where a full unit replacement or repair service through ABC Industrial Parts provides the quickest path to restoring machine operations.

Programming and Configuration
Drive setup and parameterization for the Lenze E84AVSCE1522SX0 frequency inverter are performed using Lenze L-force Engineer engineering software (version 2.6 or higher). Engineering connections can be established using the USB Diagnostic Adapter (E84EZCEUSB) attached to the front diagnostic port, or parameters can be edited directly on the machine panel using the optional plug-in Keypad X400 (E84DDFXP000). The software interface supports real-time parameter configuration, speed profile tuning, and oscilloscope function trace monitoring.
Complete parameter storage is handled via a front-accessible, pluggable EEPROM memory module chip. The memory chip stores all motor parameters, V/f and vector control profiles, safe torque off configurations, fieldbus addresses, and custom I/O mappings. Because all configuration settings reside on this physical chip, parameter sets can be duplicated or transferred without maintaining active software licenses on local field service computers.
When commissioning a spare inverter unit, parameters stored on the memory module can be loaded into the drive control unit upon power-up. Technicians can also extract or back up dataset structures via L-force Engineer to maintain master archives for facility equipment management.
Communication and System Integration
The 8400 StateLine C drive provides standard system integration capabilities through a built-in CANopen interface capable of bus communication speeds up to 1000 kbit/s. Dedicated front panel LEDs (CAN RUN and CAN ERR) report network operational states, pre-operational modes, and communication bus errors in real time.
For integration into broader higher-level industrial networks, the inverter incorporates an MCI extension slot designed for optional plug-in fieldbus modules. Supported modules include the E84AYCPM PROFIBUS-DP card, E84AYCER PROFINET card, and E84AYCET EtherCAT card, allowing flexible network alignment without altering core drive wiring.
Control terminal connections include five 24 V DC digital logic inputs and one digital logic output for hardware interlocks and control commands. Analog control features one 12-bit multi-range input accepting 0–10 V, ±10 V, or 0/4–20 mA signals, alongside one 0–10 V analog output for actual value feedback.
Diagnostics and Status Indication
Visual status diagnostics are displayed directly on the unit via four dedicated LED indicators covering general drive operation and CANopen fieldbus state. Additional diagnostic tools include the interactive menu system on the optional Keypad X400 and the diagnostic monitor inside L-force Engineer.
System state monitoring and fault tracking utilize specific internal parameters. Parameter C00150 and C00009 provide live status and operating readouts, while parameter C00160 grants direct access to the active fault memory buffer for troubleshooting trip histories.

| CAN RUN | Green - Solid / Blinking | Green solid: CANopen bus state Operational; Blinking green: Pre-Operational / Stopped. |
| CAN ERR | Red - Solid | Red solid: CANopen communication error or bus off condition. |
Replacement and Spare Part Considerations
Replacing a damaged Lenze E84AVSCE1522SX0 drive is designed to minimize downtime through the use of the removable EEPROM memory chip. By physically transferring the memory module from the original drive to the replacement unit, all motor, safety, and network parameters are retained without needing to re-commission the drive via software.
Before restoring power to a replacement unit, verify that line power input matches the required 180–264 V AC specification and that motor cable connections (U, V, W) and STO safety circuit input terminals are secured. Any installed MCI fieldbus module, such as a PROFIBUS (E84AYCPM) or PROFINET (E84AYCER) card, must be moved to the replacement drive's MCI slot.
For long-term machinery lifecycle planning, Lenze offers the i550 cabinet series as a recommended successor series. However, maintaining exact Lenze E84AVSCE1522SX0 8400 StateLine C replacement units allows direct form-fit-function replacement without control cabinet modification or PLC project redesign.
