Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 15842826, type E84AVSCE3714SX0, is a compact IP20 panel-mounted frequency inverter within the Lenze 8400 StateLine C series. Designed for precise motor speed regulation and motion control in automated machinery, this drive provides a rated power output of 0.37 kW (0.5 hp) and a continuous output current of 1.3 A. Operating from a 3-phase AC input supply ranging between 320 V AC and 528 V AC at 45 to 65 Hz, it manages 3-phase AC motors through Sensorless Vector Control (SLVC) or configurable V/f characteristic curves. With output frequencies up to 599 Hz and peak current capabilities up to 1.95 A, this unit is routinely deployed in packaging equipment, conveyor systems, industrial fans, and processing machinery.
Network integration is established via an onboard CANopen system bus capable of data transmission up to 1000 kbps, complemented by a modular expansion slot for optional fieldbus interface modules such as PROFINET, PROFIBUS, EtherCAT, or EtherNet/IP. Functional safety is built directly into the drive terminals through dual-channel Safe Torque Off (STO) compliant with SIL 3 (EN IEC 62061) and PL e (EN ISO 13849-1), eliminating the requirement for external power contactors. Commissioning a replacement unit is straightforward thanks to the pluggable EEPROM memory chip (E84AYM100). By swapping the memory card into a spare drive, parameter sets and application configurations are instantly moved without requiring a PC or software tools, with ABC Industrial Parts supplying tested spare units and parameter handling support for rapid replacement.
Real-time operational status is displayed through front diagnostic LEDs including DRV-READY, DRV-BUSY, DRV-ERR, CAN-RUN, and CAN-ERR. When drive trips occur, fault information is stored in the internal diagnostic buffer and accessed via software tools like Lenze EASY Starter or the optional X400 keypad. Initial field checks should cover input supply voltage, motor cable integrity, CAN bus 120 Ohm termination resistors, and the 24 V DC supply across safety terminals SIA and SIB. If a persistent internal hardware failure such as error H05 occurs, internal component repair is not field-serviceable, making drive replacement or exchange through ABC Industrial Parts the most practical solution to restore operation.

Programming and Configuration
Parameter adjustments and programming for the Lenze E84AVSCE3714SX0 inverter are executed using Lenze EASY Starter or Lenze Engineer software. Online connection to a PC requires the optional Lenze USB Diagnostic Adapter (E84AVZCU000) or direct mounting of the pluggable Lenze X400 Keypad (E84AVZKE000) onto the drive's diagnostic port. The engineering interface grants full configuration access to motor dynamics, switching frequency settings up to 16 kHz, acceleration and deceleration ramps, and real-time monitoring registers.
Application data and drive parameters are stored entirely on the pluggable Lenze memory chip (E84AYM100). During maintenance or hardware replacement, this chip can be removed from the original unit and inserted into the replacement inverter. This tool-free parameter swap reinstates complete drive configuration without requiring engineering software, parameter re-entry, or re-commissioning of motor constants.
Communication and System Integration
The Lenze 15842826 frequency inverter incorporates an onboard CANopen system bus interface operating at transfer rates up to 1000 kbps. It supports process data objects (PDO) and network synchronization commands, allowing immediate connectivity with CANopen master controllers. Reliable network communication requires correct node ID allocation, matching bus transmission speeds, and proper 120 Ohm termination resistors installed at both physical ends of the network line.
For integration into other fieldbus networks, the 8400 StateLine C architecture includes an extension slot for option modules. Compatible communication modules include PROFIBUS-DP (E84AYCPM), PROFINET (E84AYCER), EtherCAT (E84AYCET), EtherNet/IP (E84AYCEO), and Modbus RTU. This modular design permits flexible integration into multi-vendor industrial networks without replacing the underlying drive platform.
Diagnostics and Status Indication
Diagnostic indicators on the front panel provide visual status updates regarding operational state and communication health. Additional diagnostic evaluation is accessible online through Lenze EASY Starter software, the X400 Keypad, or CANopen status registers, all of which query the drive's fault history buffer.
When a trip condition occurs, the red DRV-ERR LED signals an active warning or fault. Persistent internal failures trigger error registers that specify electrical, thermal, or bus fault conditions.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRV-READY | Green - Solid | Drive is ready for operation / operational state. |
| DRV-BUSY | Yellow - Solid | Drive is running / processing command. |
| DRV-ERR | Red - Solid / Flashing | Fault or error state active. Red flashing indicates warning or trip condition. Persistent internal error state indicates hardware failure requiring repair/replacement. |
| CAN-RUN | Green - Solid | CANopen bus operational status. |
| CAN-ERR | Red - Solid / Flashing | CANopen bus error / bus off condition. |
Replacement and Spare Part Considerations
Before replacing a Lenze 15842826 (E84AVSCE3714SX0) inverter, confirm that the power rating (0.37 kW), voltage specification (3-phase 320–528 V AC), and physical mounting dimensions match the existing panel layout. If optional fieldbus cards such as PROFIBUS or PROFINET are installed on the original drive, transfer these expansion modules to the replacement unit prior to power-up.
Parameter setup on the replacement drive can be achieved instantly by transferring the removable EEPROM memory chip (E84AYM100) from the old unit into the spare. Ensure that safety input terminals SIA and SIB receive the required 24 V DC power supply for the dual-channel STO circuit. For facilities migrating away from the 8400 StateLine C family, the recommended successor series is the Lenze i550 cabinet frequency inverter.
