Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 15135540 (type E94ASHE0024A22ENNN) is a single-axis servo drive in the Lenze 9400 HighLine family designed for high-precision positioning and multi-axis motion control. Operating on a nominal 3-phase 400/480 V AC supply across a 320 to 528 V AC range, this panel-mounted servo drive delivers a rated output power of 0.75 kW with a continuous current rating of 2.5 A and a peak current capability of 5 A at a 4 kHz switching frequency. To ensure functional safety without additional panel contactors, the unit integrates a Safe Torque Off (STO) module alongside an onboard brake chopper to absorb regenerative energy in dynamic packaging, automated handling, or textile processing machinery.
Integrating a replacement drive into an existing control system relies on matching both fieldbus interfaces and parameter code. The E94ASHE0024A22ENNN provides standard onboard CANopen connectivity over dual RJ45 connectors, supplemented by multi-encoder feedback terminals supporting resolvers, SinCos, Hiperface, EnDat, SSI, TTL, and HTL encoder systems. Two option slots accept modular communication hardware such as the E94AYCER PROFINET, E94AYCET EtherCAT, E94AYCPM PROFIBUS-DP, or E94AYCEO EtherNet/IP interface cards. Putting a spare unit into operation can be completed without a PC or software tools by transferring the removable MM200 or MM300 memory module from the original drive, which holds all drive parameters, application code, and firmware settings. ABC Industrial Parts can assist maintenance teams with spare unit preparation, fieldbus option selection, and hardware verification.
Real-time monitoring and fault isolation are managed through front-panel LEDs and onboard software diagnostics. Status indicators include DRV-RDY for drive readiness, DRV-ERR for fault conditions, CAN RUN for system bus status, and CAN ERR for bus errors or parameter mismatches. Diagnostic data is also captured within a logbook on the memory module and accessible through the E94AZKCE keypad, E94AZCUS USB adapter, or L-force Engineer and EASY Starter software. Common field issues include mains undervoltage, motor earth faults, feedback cable disconnection, or STO input discrepancies. If the DRV-ERR LED remains solid red or code 0x0020 occurs after a full power reset, an internal hardware failure has occurred that is not field-serviceable, requiring drive repair or replacement through ABC Industrial Parts.

Programming and Configuration
Drive commissioning, parameter adjustments, and program development for the Lenze 15135540 E94ASHE0024A22ENNN servo drive are managed through the Lenze L-force Engineer and EASY Starter software suites. Connecting a PC to the drive for real-time monitoring and parameter transfer can be accomplished using the E94AZCUS USB diagnostic adapter or via an attached fieldbus network. Handheld local configuration is also supported using the pluggable E94AZKCE keypad.
Rapid unit replacement without software tools is enabled by the removable MM200 or MM300 memory module. All operational parameters, customer application programs, and firmware configurations reside on this memory card. Transferring an existing card to a replacement drive restores identical operating parameters and network node configurations immediately upon power-up.
Communication and System Integration
The Lenze 15135540 features standard onboard CANopen system bus capability accessed through dual RJ45 ports, allowing multi-axis bus synchronization and real-time motion control integration. Bus status is monitored directly via dedicated CAN RUN and CAN ERR status indicators on the front panel.
For broader control architecture integration, the 9400 HighLine drive includes two modular option slots. These slots accommodate fieldbus expansion modules including E94AYCER for PROFINET, E94AYCET for EtherCAT, E94AYCPM for PROFIBUS-DP, and E94AYCEO for EtherNet/IP. Universal encoder inputs handle feedback signals from resolvers, SinCos, Hiperface, SSI, EnDat, TTL, and HTL feedback units.
Diagnostics and Status Indication
Diagnostic feedback for the E94ASHE0024A22ENNN drive is provided via visual indicators, software diagnostic mapping, and an internal diagnostic logbook recorded on the plug-in memory card. Technicians can view system state information using the E94AZKCE handheld keypad display, L-force Engineer, or EASY Starter software.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRV-RDY | Green - Solid / Flashing | Green: Controller is ready for operation. Flashing: Initialization active or waiting for enable. |
| DRV-ERR | Red - Solid / Flashing | Red solid/flashing: Active fault or error condition. Internal hardware fault if persistent after power reset. |
| CAN RUN | Green - Solid | CANopen system bus operational. |
| CAN ERR | Red - Solid / Flashing | CANopen bus error or configuration mismatch. |
Replacement and Spare Part Considerations
Replacing a Lenze 15135540 9400 HighLine drive requires matching the hardware model number E94ASHE0024A22ENNN to ensure equivalent 0.75 kW power ratings, continuous 2.5 A current limits, and integrated STO functional safety capabilities. Verify that installed communication options—such as PROFINET or EtherCAT modules—are moved to the replacement drive's expansion slots prior to mounting.
Drive commissioning during unit replacement is streamlined by moving the MM200 or MM300 memory module from the original drive directly into the spare unit. This transfers all stored motion parameters, safety configurations, and network addresses without requiring a PC connection. Before placing the machine back into service, check line voltage supplies, motor encoder cabling, and safety circuit signals to verify proper operating conditions.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
