Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E84AVSCE5512SB0 is an industrial frequency inverter from the 8400 StateLine C product line within the Lenze 8400 Series. Designed for speed-controlled three-phase AC motor drive applications in conveyor systems, pumps, fans, and packaging machinery, this compact panel-mount unit operates on a 230 V AC supply voltage with an operating range of 180 V to 264 V AC. It delivers a rated output power of 0.55 kW with a 3 A continuous output current and a 6 A mains input current. Motor control is driven through linear or quadratic V/f characteristic control or Sensorless Vector Control (SLVC), supporting an output frequency range from 0 to 599 Hz with switching frequencies up to 16 kHz for quiet motor operation. Functional safety is integrated directly into the hardware through Safe Torque Off (STO), certified to SIL 3 per EN 62061 and PL e per EN ISO 13849-1, eliminating the requirement for external safety contactors in emergency stop loops.
For network and field control, the E84AVSCE5512SB0 incorporates an onboard CANopen system bus capable of communication rates up to 500 kbit/s, along with hardwired terminals providing 5 digital inputs, 1 digital output, 1 relay output, 1 analog input, and 1 analog output. Industrial communication capabilities can be expanded using optional plug-in modules, such as the E84AYCPM PROFIBUS module, E84AYCER PROFINET module, or E84AYCET EtherCAT module, as well as EtherNet/IP and Modbus TCP units. Engineering setup is supported via Lenze EASY Starter or L-force Engineer software, or directly at the drive using the pluggable L-force Diagnostics Keypad X100 (EZAEBK1001). Commissioning a replacement unit is straightforward thanks to the removable Lenze E84AYM200 EEPROM memory module. Transferring the original memory card into a replacement drive copies the complete parameter set instantly without software tools or PC connectivity. When configuring or recovering parameter files, ABC Industrial Parts provides technical support and tested replacement hardware to get machines back into operation.
Drive diagnostic states are shown on the front panel via status LEDs, including DRV-READY for operational status, DRV-ERR for active trip faults and warnings, CAN-RUN for CANbus network status, and CAN-ERR for bus communication errors. Active status registers and the fault buffer can also be interrogated over fieldbus connections or read out using EASY Starter software or the X100 keypad. When a fault occurs—such as short circuit/overcurrent (OC1), DC bus overvoltage (OU), or heatsink overtemperature (OH)—initial checks should focus on motor winding insulation, mains input voltage, and cabinet ventilation. For non-recoverable internal micro-controller or hardware supervisory failures represented by code 0x00110001, internal components cannot be serviced in the field. In situations where internal board faults persist after power cycling, obtaining a fully tested replacement drive or utilizing exchange units through ABC Industrial Parts ensures rapid recovery of machine operations.

Programming and Configuration
Drive setup and parameter adjustments for the Lenze E84AVSCE5512SB0 are managed using Lenze EASY Starter or L-force Engineer commissioning tools. These software packages allow technicians to configure motor parameter sets, adjust acceleration and deceleration ramp times, define V/f or Sensorless Vector Control (SLVC) curves, and assign function logic to the onboard digital and analog terminals.
Parameter management and offline backups rely on the pluggable Lenze E84AYM200 EEPROM memory module. All operational parameters are stored directly on this module, allowing full device parameters to be preserved independently of the main controller hardware. Local parameter monitoring and parameter adjustments can also be executed at the machine enclosure using the optional Lenze L-force Diagnostics Keypad X100 (EZAEBK1001), which mounts onto the drive front interface.
Communication and System Integration
The E84AVSCE5512SB0 includes an integrated CANopen system bus interface operating up to 500 kbit/s. This built-in protocol provides direct real-time communication, operational command transfer, and parameter exchange across CANbus automation networks without requiring optional network cards.
To integrate into higher-level industrial network structures, the 8400 StateLine C inverter accepts plug-in fieldbus extension modules. Supported options include the E84AYCPM PROFIBUS DP module, E84AYCER PROFINET module, and E84AYCET EtherCAT module, as well as modules for EtherNet/IP and Modbus TCP. Hardwired control signals interface via 5 digital inputs, 1 digital output, 1 relay output, 1 analog input, and 1 analog output.
Diagnostics and Status Indication
Operational status and network conditions are monitored through four status LEDs located on the inverter front panel. These LEDs provide real-time status reporting for the drive power stage, general fault conditions, and active CANopen bus communication.
Comprehensive diagnostic routines can be performed by interrogating the drive error buffer using EASY Starter software or the L-force Diagnostics Keypad X100 (EZAEBK1001). Status words and fault memory logs are also continuously accessible via the CANopen system bus or installed fieldbus extension modules.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRV-READY | Green - Solid / Flashing | Solid Green = Ready / Running; Flashing Green = Drive enabled / operation active |
| DRV-ERR | Red - Solid / Flashing | Solid Red = Active trip fault / lockout; Flashing Red = Warning or minor fault |
| CAN-RUN | Green - Operational | Indicates CANbus network operational state |
| CAN-ERR | Red - Error | Indicates CANbus network communication error |
Replacement and Spare Part Considerations
When selecting a spare drive for the E84AVSCE5512SB0, verify that the replacement matches the specific part number and power rating of 0.55 kW with a 230 V AC supply. Because full device configurations are stored on the pluggable E84AYM200 memory card, physical unit replacements can be completed by moving the memory module from the original drive to the spare unit, restoring operational parameters without requiring engineering software.
If the unit uses optional fieldbus modules—such as PROFIBUS (E84AYCPM), PROFINET (E84AYCER), or EtherCAT (E84AYCET)—unclip these cards from the existing drive and transfer them to the replacement unit, ensuring any DIP address switches or rotary selectors are aligned with original network settings. For long-term equipment lifecycle planning, the Lenze i550 cabinet inverter series (part number i55AE155B00000000S) serves as the functional successor to this series.
