LENZE E94ASHE0474 High Performance Servo Controller

LENZE E94ASHE0474
Basic Information
Full name: Lenze 9400 HighLine single axis servo controller
Series: L-force 9400 HighLine
Model analysis
E94A=9400 series single axis drive
S=Standard heat dissipation
HE=HighLine (high-end model, built-in process functions such as motion PLC, electronic cam, flying shear, electronic gear, etc.)
0474=rated output current 47A, three-phase 400V level

1、 Discontinued state (core)
✅ The original factory officially discontinued EOL production (Obsolvete)
Luntz official 9400 full series elimination plan:
Stop mass production: 2019
Last Buy: End of 2021
Original factories will no longer accept new orders after 2022
Maintenance Support Policy
Original hardware repair support will continue until 2028 (spare parts repair channel still exists, but the repair cycle is long and the cost is high)
Market source: Global inventory of new machines, refurbished repair parts, and second-hand dismantled machines; No original factory futures can be ordered
2、 Key electrical parameters
Power supply: DC bus 250-1000 VDC (used in conjunction with 9400 power module, multi axis common DC bus scheme)
Rated output current: 47 A
Suitable motor power: approximately 22kW 400V servo motor
Pulse frequency: 4kHz (adjustable carrier)
Feedback Interface: Rotary Transformer+Universal Encoder Interface (EnDat, SinCos, TTL)
Onboard IO: 9DI/4DO/2AI/2AO
Communication Expansion: Optional PROFIBUS, PROFINET, EtherCAT, CANopen communication modules (E94AYxxx series)
Safety function: STO safety torque cut-off (basic safety)
3、 Model differentiation (easily confused)
table
Model, current, version, difference, interchangeability
E94ASHE0474 47A HighLine with motion PLC target model
E94AMHE0474 47A MultiDrive multi axis module (with built-in busbar and different appearance) cannot be directly interchanged
E94ASSE0474 47A StateLine basic model, incompatible with built-in process PLC program, cannot directly replace HE version
⚠️ The firmware functions of HE (HighLine) and SE (StateLine) differ greatly, and cannot be mixed when the on-site program has cam and flying shear processes.
4、 Original factory alternative solution
Directly plug and unplug compatible models without hardware!
The hardware structure, terminal definition, and software engineer of 9400 are all independent, and the new generation driver cannot be directly replaced on the machine.
Luntz Replacement Platform: i950 Servo Drive
Corresponding power level selection substitution; It is necessary to rewire, rewrite the motion program, and debug the entire machine, which requires a large amount of renovation work.
Prioritize the procurement of inventory spare parts for the maintenance of existing production lines.
5、 Key Reminders for Procurement Inspection and Foreign Trade
Differentiate the source of goods: original inventory of new machines (scarce)>refurbished complete machines>dismantled second-hand machines; The proportion of market renovation is relatively high;
Be sure to confirm: complete set of driver body and supporting communication module (if any);
Software Attention: Use Lenze Engineer V3. x for debugging; The new version of the software no longer supports 9400;
It is recommended to strive for a warranty of at least 6 months for discontinued spare parts;
Check whether the busbar terminals and motor terminals are corroded, and capacitor aging is a common fault point for this model.
