Lenze 13400416 E94ASHE0074 – 9400 StateLine 3kW Servo Drive
Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13400416, designated by model type E94ASHE0074, is a 3.0 kW single-axis servo inverter belonging to the Lenze 9400 StateLine series. Engineered for precision multi-axis motion and dynamic torque management, this panel-mounted drive operates from a 3-phase AC supply spanning 320 V to 528 V at 45 to 65 Hz. It delivers a continuous output current of 7.0 A, with peak current ratings supporting 14.0 A for 60 seconds and temporary bursts up to 21.0 A for 3 seconds. An integrated forced-air cooling system maintains continuous thermal stability during intensive operating cycles.
Connection and integration options accommodate a wide range of feedback systems and fieldbus architectures. Motor feedback connects through a dedicated resolver terminal (X7) or a universal encoder port (X8) supporting SinCos, Hiperface, EnDat 2.1/2.2, SSI, HTL, and TTL devices. Onboard communication features an integrated CANopen system bus alongside an RJ45 Ethernet diagnostic interface (X6). Two module slots allow system expansion using optional fieldbus cards such as PROFIBUS, PROFINET, EtherNet/IP, or EtherCAT. Parameter commissioning during replacement is simplified through pluggable MM200 or MM300 smart memory cards, allowing field technicians to copy stored drive settings directly without engineering software.
Front-panel visual status indication provides rapid status checks for drive operational state, system readiness, and bus communication. Diagnostic readouts and plain-text message displays can be accessed via the optional Keypad XT (E94AZKXE) module or through PC connection. If the red ERR LED stays continuously lit at power-up, an internal hardware failure is indicated that cannot be resolved in the field. For defective units experiencing internal component failures, ABC Industrial Parts provides tested replacement units and repair support to quickly restore machine operation.

Programming and Configuration
Drive setup, parameter adjustment, and diagnostic monitoring for the Lenze E94ASHE0074 are performed using Lenze EASY Starter or Lenze Engineer software packages. Connection to a programming PC is established through the onboard RJ45 Ethernet diagnostic connection (X6) or using an optional E94AZCUS USB diagnostic adapter.
Parameter persistence and field replacement are managed using pluggable MM200 or MM300 memory smart cards. Operational parameters stored on the memory card transfer automatically when inserted into a replacement drive, removing the requirement to perform PC-based parameter downloads during drive swaps.
Communication and System Integration
The Lenze 13400416 includes a built-in CANopen system bus interface for system control and inter-drive synchronization. Online software diagnostics and PC connections utilize the onboard 10/100 Mbit/s RJ45 Ethernet port (X6).
To enable communication with higher-level PLCs and main control networks, the drive includes two expansion module slots. Optional fieldbus modules supported include PROFIBUS-DP (E94AYCPM), PROFINET (E94AYCER), EtherNet/IP (E94AYCEO), and EtherCAT (E94AYCET).
Diagnostics and Status Indication
Operational evaluation on the Lenze E94ASHE0074 is supported by front panel LED indicators, an optional Keypad XT (E94AZKXE) text display, internal fault logbooks, and PC-based trace tools using EASY Starter software.
Four status LEDs on the front panel display the real-time operational status of the drive and CANopen bus. A continuous red ERR LED upon power application indicates an unserviceable internal hardware condition.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| CAN-RUN | Green - Flashing / Continuous | CANopen bus operational state: Green flashing = pre-operational, Green continuous = operational state |
| CAN-ERR | Red - Flashing / Continuous | CANopen communication error: Red flashing = warning level reached, Red continuous = bus off or CAN physical error |
| DRV-READY | Green - Flashing / Continuous | Drive status: Green continuous = drive ready for operation, Green flashing = drive inhibited |
| ERR | Red - Flashing / Continuous | Drive fault state: Red flashing = warning active, Red continuous = fault active requiring reset. Continuous illumination at power-up indicates internal hardware failure requiring replacement |
Replacement and Spare Part Considerations
When replacing a unit, confirm that the spare matches part number 13400416 and model type E94ASHE0074 to match the 3.0 kW power and 7.0 A continuous output current capabilities. Optional fieldbus modules installed in the expansion slots must be transferred to the replacement unit.
Parameter configuration can be completed tool-free by transferring the existing MM200 or MM300 memory smart card to the spare unit. ABC Industrial Parts offers support for acquiring replacement units and repairing failed drives from the Lenze 9400 series.

Frequently Asked Questions
How do I transfer drive parameters to a replacement Lenze E94ASHE0074?
Parameters are transferred by moving the pluggable MM200 or MM300 memory card from the original drive into the replacement unit. The drive automatically loads the saved parameter set when powered up.
Which motor feedback types are compatible with the E94ASHE0074?
The drive includes a dedicated resolver input (X7) and a multi-encoder connector (X8) supporting SinCos, Hiperface, EnDat 2.1/2.2, SSI, HTL, and TTL encoder types.
What does a solid red ERR LED mean upon power-up?
A continuous red ERR LED at power-up indicates an internal electronic hardware failure. If power cycling does not clear the error, the unit contains an unserviceable board fault and requires repair or replacement.
What engineering software is used to connect to the drive?
The drive is configured using Lenze EASY Starter or Lenze Engineer software over the onboard RJ45 Ethernet diagnostic connection (X6) or using an E94AZCUS USB adapter.
Can the E94ASHE0074 drive communicate over PROFINET or PROFIBUS?
Yes. While CANopen is built into the base drive, PROFINET (E94AYCER) and PROFIBUS-DP (E94AYCPM) communications can be established by installing the corresponding expansion module into the drive's option slots.
