Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze E94ASHE0034A22PMNN (Type E94ASHE0034) is a single-axis servo inverter from the Lenze 9400 HighLine series designed for high-dynamic positioning and motion control applications. Operating on a 3-phase 400 V or 480 V AC power supply, this compact 1.5 kW drive provides a continuous rated output current of 3.4 A. The unit is equipped with versatile onboard interfaces, including a Sub-D 9-pin resolver connection and a Sub-D 15-pin universal multi-encoder interface supporting SinCos, Hiperface, EnDat, and SSI feedback. Its modular structure and flexible input/output configuration make it an essential motion controller across packaging, textile, and logistics automated machinery.
For system control and fieldbus communication, the drive features an onboard CANopen system bus interface accessible via terminal block and RJ45 connections, along with modular expansion slots that accommodate fieldbus cards such as PROFINET (E94AYCER), EtherCAT (E94AYCEI), PROFIBUS-DP (E94AYCPM), and EtherNet/IP (E94AYCEN). Onboard I/O includes 9 digital inputs, 4 digital outputs, 2 analog inputs (-10 V to +10 V), and 2 analog outputs (0 V to +10 V). Commissioning, parameter adjustments, and firmware configuration are managed using Lenze L-force Engineer or EASY Starter software. When replacing an existing unit, tool-free parameter migration is achieved by transferring the pluggable E94AYM2200 memory module from the original drive, which automatically restores parameter sets and application logic upon power-up without requiring software tools. ABC Industrial Parts can assist in sourcing compatible replacement drives and configuring units prior to deployment.
Diagnostic feedback is available directly through front-panel LED status indicators, including the DRV drive status LED, CAN communication LED, and IMP/STO state LED. Detailed diagnostic registers and fault history buffers are accessible via the CANopen network or software diagnostic monitors in L-force Engineer and EASY Starter. The drive actively monitors critical operational parameters, signaling faults such as heatsink overtemperature (0x0011), DC bus overvoltage (0x0051), or encoder feedback failure (0x0081). First-line troubleshooting involves checking mains supply lines, fieldbus cable connections, 120-ohm termination resistors, and encoder feedback wiring. If persistent overcurrent or system execution errors occur without connected motor loads, internal board-level faults are present, making professional repair or a tested exchange unit from ABC Industrial Parts the quickest solution to resume operation.

Programming and Configuration
Engineering and parameterization of the Lenze E94ASHE0034A22PMNN drive are performed using the Lenze L-force Engineer or Lenze EASY Starter software suites. These tools provide diagnostic monitoring, axis parameter alignment, motion task setup, and project download functions over connected fieldbus or service interfaces.
The drive utilizes the pluggable Lenze E94AYM2200 memory module as its non-volatile storage medium. Complete parameter structures, motor configuration data, and compiled application code reside directly on this module, enabling simple parameter backup and tool-free drive cloning.
Communication and System Integration
The E94ASHE0034 unit features an integrated CANopen system bus interface supporting direct wiring via terminal blocks or RJ45 network cabling. This native interface enables real-time synchronization between multi-axis drive groupings and central machine controllers.
To integrate into secondary plant networks, the drive includes modular expansion slots that accommodate optional fieldbus modules. Supported communication extensions include PROFINET (E94AYCER), EtherCAT (E94AYCEI), PROFIBUS-DP (E94AYCPM), and EtherNet/IP (E94AYCEN).
Diagnostics and Status Indication
The front panel of the servo drive provides visual diagnostic indicators for rapid status determination during maintenance routines. Dedicated status LEDs report overall drive status, system bus communication state, and safety circuit condition.
Advanced diagnostic data, including historical fault logs and operational register states, can be interrogated using the L-force Engineer Diagnostic Monitor or EASY Starter Diagnostic View via CANopen or fieldbus connectivity.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| DRV | Green / Yellow / Red - Green / Yellow / Red | Drive status indicator (Green = Ready/Operation, Yellow = Warning, Red = Fault condition) |
| CAN | Green / Red - Green / Red | System bus communication status indicator (Green = Operational, Red = Bus Error/Off) |
| IMP / STO | Green / Off - Green / Off | Pulse inhibit / Safe Torque Off state (Green = Inhibit active, Off = Power stage enabled) |
Replacement and Spare Part Considerations
Replacing a failed E94ASHE0034A22PMNN drive requires verifying that the replacement unit matches the frame size and electrical ratings (1.5 kW, 3.4 A, 400/480 V AC). Tool-free drive replacement is supported by moving the existing E94AYM2200 memory module from the damaged unit directly into the replacement drive.
Upon initial power-up, the replacement drive reads all parameter configurations, node addresses, and application logic directly from the transferred memory module. Ensure optional communication cards (such as PROFINET or EtherCAT modules) are reinstalled into identical slot locations to maintain proper fieldbus network operation.
