Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13400419 (model E94ASHE0244) is an 11 kW servo drive from the Lenze 9400 HighLine product family, engineered for precise dynamic motion control and axis synchronization in industrial automation systems. Operating from a three-phase mains supply voltage range of 320 to 528 V AC (3 x 400/480 V AC nominal), it delivers up to 24.5 A continuous output current with an output frequency range of 0 to 599 Hz. This panel-mount drive controls synchronous servo motors such as the Lenze MCA and MCS series, asynchronous AC motors with encoder feedback, and open-loop V/f configurations. It integrates advanced motion functionality onboard, handling point-to-point positioning, electronic gearboxes, and complex electronic cam profiling to minimize central PLC computing load.
System connectivity and control integration are facilitated by onboard input and output interfaces alongside flexible expansion options. The unit provides 8 digital inputs, 4 digital outputs, 2 analog inputs (±10 V), and 2 analog outputs (±10 V), along with a universal X8 multi-encoder interface supporting Resolver, SinCos, Hiperface, EnDat 2.1/2.2, and SSI feedback devices. Distributed networking is managed through an integrated CANopen system bus operating up to 1 Mbit/s, while Option Slot 2 supports communication cards like the E94AYCER PROFINET or E94AYCEC EtherCAT modules. Commissioning a spare drive relies on pluggable MM200 or MM300 parameter memory modules, which hold all parameter sets, motor profiles, and application code. Swapping this memory card into a replacement drive enables fast, hardware-based unit replacement without a laptop. ABC Industrial Parts can assist maintenance teams with donor parameter transfer and drive preparation.
Drive operational status and diagnostic messages are indicated through front-panel LED indicators, an optional pluggable E94AZKAE keypad, or software diagnostic buffers in Lenze Engineer and EASY Starter. When troubleshooting abnormal drive behavior, first-line verification should cover mains supply voltage, DC bus level, motor cable insulation, encoder shield grounding at connector X8, and safety circuit interlocks. Fault conditions such as a solid red DRV-ERR LED across power resets or immediate overcurrent trips with no motor connected point to internal power stage or sensing circuit failures that are not field-serviceable. In these cases, ABC Industrial Parts offers comprehensive repair services and fully tested exchange drives to restore operating conditions quickly.

Programming and Configuration
The Lenze 13400419 E94ASHE0244 drive features advanced internal motion control logic configured through Lenze Engineer or EASY Starter software packages. The drive firmware supports point-to-point positioning routines, electronic gear ratios, and complex electronic cam profiling directly onboard, reducing the burden on main PLC CPUs in high-speed packaging, gantry, and converting machinery.
All parameter sets, motor calibration data, and application programs reside on removable MM200 or MM300 memory modules. When replacing a unit in the field, moving the existing memory module into the replacement servo drive transfers the complete configuration without requiring a computer or software connection.
Communication and System Integration
System integration is supported natively via an onboard CANopen system bus capable of transmission speeds up to 1 Mbit/s. This allows tight multi-axis synchronization and rapid exchange of control registers across automated networks.
For higher-level network integration, Option Slot 2 accepts modular communication cards including the E94AYCER PROFINET and E94AYCEC EtherCAT modules, as well as PROFIBUS-DP and EtherNet/IP options. Option Slot 1 is dedicated to functional safety modules, accommodating Safety01 through Safety03 modules for safe motion supervision.
Diagnostics and Status Indication
Real-time diagnostic capability includes status LEDs on the front panel, an optional E94AZKAE pluggable keypad unit displaying plain-text error messages, diagnostic buffer logs accessible via Lenze Engineer and EASY Starter software, and CANopen diagnostic register inspection.
The four dedicated LEDs provide immediate status breakdown for both CANopen network activity and internal drive controller states, allowing technicians to isolate bus failures from internal hardware trips.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| CAN-RUN | Green - Solid / Blinking / Off | CANopen bus state indicator. Solid = Operational; Blinking = Pre-operational; Off = Bus off / Stopped. |
| CAN-ERR | Red - Solid / Flashing | CANopen communication error indicator. Solid or flashing indicates bus warning or bus off condition. |
| DRV-READY | Green - Solid / Blinking | Drive operational status. Solid = Controller enabled and active; Blinking = Drive ready, controller inhibited. |
| DRV-ERR | Red - Solid | Fault indicator. Solid red indicates active error/trip condition. Persistent red across power cycles indicates internal board failure. |
Replacement and Spare Part Considerations
When swapping a Lenze 13400419 E94ASHE0244 drive, ensure the replacement unit matches the required power rating (11 kW) and physical mounting frame (Panel Mount E Type). Check that option cards inserted in Option Slot 1 (Safety modules) and Option Slot 2 (Fieldbus modules such as E94AYCER PROFINET or E94AYCEC EtherCAT) are transferred to the replacement unit in identical configurations.
The MM200 or MM300 parameter memory module allows zero-tool parameter transfer during unit replacement. Carefully transfer the card from the original drive to the spare drive before powering up. Verify that motor feedback settings on multi-encoder port X8 match connected synchronous motors (such as Lenze MCA or MCS series) or asynchronous motor configurations.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| 0x00110001 | OC1 Short Circuit / Overcurrent | Instantaneous current threshold exceeded on motor output phases U, V, W. | Short circuit in motor winding or power cable, ground short, acceleration rate too steep. | Check motor cable and insulation resistance, verify motor parameters, increase acceleration time. If trip occurs instantly without motor connected, internal IGBT power stage failure detected — return unit for repair. |
| 0x00120001 | Earth Fault | Ground fault current detected on output channels. | Insulation breakdown in motor winding, pinched output cable, excessive earth leakage current. | Check output cable and motor with insulation tester. If cable and motor pass insulation tests, internal current sensing circuit fault requires repair. |

If safety inputs match and error persists, safety module internal hardware fault — replace safety module or return drive for repair. |
Frequently Asked Questions
Which programming software is required to configure the Lenze E94ASHE0244 servo drive?
The drive is commissioned and programmed using Lenze Engineer or EASY Starter software tools. Alternatively, basic parameter changes and status checks can be performed using the pluggable E94AZKAE keypad unit.
How do I transfer drive parameters when replacing a failed 13400419 drive?
All parameter data, motor profiles, and application code are stored on the pluggable MM200 or MM300 memory module. Removing the module from the original drive and inserting it into the replacement drive transfers all configuration data without needing software or a laptop.
What encoder types are supported on the X8 feedback interface?
The universal X8 multi-encoder interface supports Resolver, SinCos, Hiperface, EnDat 2.1/2.2, and SSI feedback encoder types.
What optional fieldbus communication modules can be added to Option Slot 2?
Option Slot 2 supports optional communication cards including the E94AYCER PROFINET module and the E94AYCEC EtherCAT module, as well as PROFIBUS-DP and EtherNet/IP interface modules.
What does a persistent red DRV-ERR LED indicate on the Lenze 13400419 drive?
A solid red DRV-ERR LED indicates an active trip condition. If the red light remains solid across power cycles or trips immediately upon power-up without a connected motor, an internal hardware failure on the power or sensing board has occurred, requiring drive repair or replacement.
