Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze 13042310 (Model E94ASHE0074) is a single-axis servo drive from the 9400 HighLine family, designed for high-dynamic motion control, electronic gearing, and precision positioning applications. Operating from a 3-phase AC line supply ranging from 320 V to 528 V AC (rated 3 AC 400/480 V), this 3.0 kW servo inverter delivers a continuous rated output current of 7.4 A with a peak output current capacity of 14.8 A for up to 5 seconds. To support broad motor compatibility, the drive includes dedicated onboard feedback connections comprising a Sub-D 9-pin resolver input and a Sub-D 15-pin multi-encoder input compatible with SinCos, Hiperface, SSI, and incremental encoders.
Onboard system integration is supported through dual RJ45 interfaces configured for CANopen fieldbus communication at speeds up to 1000 kbps, complemented by two expansion slots for option cards such as PROFINET, EtherCAT, PROFIBUS-DP, or EtherNet/IP, as well as a dedicated internal slot for an STO safety module. When replacing a damaged unit, service downtime is minimized by transferring the pluggable E94AYMxx memory module, which holds all parameters, firmware, and user logic directly to the spare hardware without requiring a PC. For custom setups or parameter adjustments, Lenze Engineer Software v2.0 or higher is utilized, and ABC Industrial Parts can assist with supply and preparation of replacement units.
System health and operational state are indicated by four front panel status LEDs—Ready, Error, CAN Run, and CAN Err—alongside the X6 diagnostic port and optional E94AZKCE keypad display. Initial troubleshooting involves checking incoming 3-phase mains voltage, verifying feedback wiring on connectors X7 and X8, and inspecting fieldbus termination settings. When encountering unrecoverable internal control errors or continuous red error illumination, internal repair is required, and returning the unit to ABC Industrial Parts for testing or service provides an efficient path back to operation.

Programming and Configuration
Engineering and parameter setting for the Lenze 13042310 E94ASHE0074 servo inverter are performed using Lenze Engineer Software version 2.0 or higher. The software environment provides an online diagnostic dashboard, parameter management, motion control profiling, and configuration tools for electronic gearing and multi-axis positioning functions.
To simplify hardware replacements in the field, the drive uses pluggable E94AYMxx hardware memory modules. The memory module stores the complete parameter set, device firmware, and application logic. Swapping this module into a replacement drive allows immediate commissioning without connecting a PC. Local parameter monitoring and drive setting adjustments can also be conducted using an optional E94AZKCE keypad module.
Communication and System Integration
System integration for the Lenze 9400 HighLine E94ASHE0074 drive relies on integrated dual RJ45 CANopen interfaces capable of communication rates up to 1000 kbps. The drive includes 8 digital inputs, 4 digital outputs, 2 analog inputs (±10 V), and 2 analog outputs (±10 V) for direct I/O control and signal monitoring.
For integration into major industrial Ethernet networks, the unit provides two expansion slots that accept option modules including E94AYCER / E94AYCEN PROFINET cards, E94AYCET EtherCAT cards, PROFIBUS-DP, or EtherNet/IP interfaces. A dedicated internal safety slot also supports the installation of an E94AYAE STO module to implement Safe Torque Off safety functions.
Diagnostics and Status Indication
Diagnostic monitoring on the Lenze E94ASHE0074 drive is facilitated through four status LEDs located on the front panel, an X6 diagnostic port, and online diagnostics via Lenze Engineer software. System states and CAN network activity are displayed via dedicated indicators, while active fault logs are archived in the removable memory module.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Ready | Green - Solid / Flashing | ON: Drive initialized and operational; Flashing: Drive in ready state / switch-on inhibit |
| Error | Red - Solid / Flashing | ON: Active trip/fault condition; Flashing: Active warning or trouble state; Continuous illumination without display indicates internal hardware failure |
| CAN Run | Green - Solid / Flashing | ON: CANopen operational; Flashing: Pre-operational state |
| CAN Err | Red - Solid / Flashing | ON: CAN bus off / error limit reached; Flashing: Guarding or heartbeat failure |
Replacement and Spare Part Considerations
Before installing a replacement Lenze 13042310 (E94ASHE0074) drive, ensure that the power supply voltage (320 - 528 V AC) and output current ratings match the machine requirements. Confirm that any optional fieldbus communication modules (such as PROFINET or EtherCAT) and safety option cards (such as the E94AYAE STO module) are transferred from the original unit to the replacement drive.
To complete a rapid swap without commissioning tools, move the pluggable E94AYMxx memory module from the original unit directly into the replacement drive. The card automatically loads all parameters, logic functions, and firmware settings. For plant modernizations, the Lenze i950 Servo Inverter is identified as the recommended successor model.
Error Codes & Fault Codes
The following error codes may be displayed during operation or diagnostics:
| Code | Name | Description | Possible Cause | Recommended Action |
|---|---|---|---|---|
| 0x0010 | Short circuit / Earth fault | Peak output current threshold exceeded due to short circuit or earth fault at motor outputs. | Short circuit in motor cable, phase-to-phase fault, motor winding isolation breakdown, or defective inverter power stage. | Check motor cabling and insulation resistance. Check motor for short circuit. If fault persists with motor disconnected, internal power stage is damaged — return unit for repair. |
| 0x0020 | DC bus overvoltage | DC bus voltage exceeded upper limit. | Excessive regenerative energy during deceleration, brake resistor disconnected or defective, brake chopper failure, or supply mains voltage too high. | Increase deceleration ramp time, check brake chopper parameters, verify external brake resistor resistance and wiring, measure line voltage. |
| 0x0030 | DC bus undervoltage | DC bus voltage dropped below minimum threshold during operation. | Mains voltage failure, power line supply phase loss, incoming circuit breaker tripped. | Check mains voltage supply, fuses, line contactor, and AC power connections. |
| 0x0041 | Motor overtemperature | Motor temperature sensor reported overtemperature. | Motor thermal overload, continuous operation at high torque, defective motor blower/cooling, incorrect sensor evaluation parameters. | Allow motor to cool down, check motor load and cooling fan, verify temperature sensor connections (PTC/KTY). |
| 0x0042 | Inverter heatsink overtemperature | Heatsink temperature of the servo drive exceeded maximum allowed threshold. | Inadequate control cabinet ventilation, clogged heatsink cooling fins, internal fan failure, ambient temperature too high. | Clean heatsink, ensure adequate spacing around drive, check internal cabinet fan, lower ambient temperature. |
| 0x0050 | Feedback system error | Signal loss or invalid feedback signals from resolver or encoder. | Disconnected encoder cable, cable shielding fault, bad connector pin contact, encoder power supply failure, or defective encoder. | Check resolver/encoder cable, connectors X7/X8, check shield grounding. Replace encoder cable or motor feedback sensor. |
| 0x0070 | Communication failure | Communication timeout on CANopen or fieldbus option module. | Fieldbus master stopped, loose bus cable, missing bus termination resistor, incorrect baud rate or node address setting. | Check fieldbus wiring, termination resistors, master controller status, and communication settings in drive. |
| 0x00A0 | Internal hardware failure | Internal self-test failed or system microcontroller error occurred. | Internal memory corruption, failed board component, control board defect. | Cycle logic power. If failure persists, internal hardware fault — replace the drive unit or return to Lenze service for repair. |
