- Opciones de reemplazo (Importante: No pintopin dropin compatible replacement; hardware, wiring and software must be reworked completely)
Conclusión: There is no plugandplay alternative. Two strategies: equipment retention via repair; or fullsystem upgrade.
Strategy 1: Repairbased retention of existing machine
Source used / secondhand CDE32.003.C2.4. Riesgos: limited availability, component ageing. Powerboard inspection and capacitor refurbishment recommended.
Verify firmware version and encoder type (EnDat 2.2) for matching with existing motor.
Strategy 2: Full upgrade (KEBA successor & 3rdparty servos)
- KEBA KeDrive D3 series (technical inheritance from LUST): Requires new electrical drawings, encoder reconfiguration. DriveManager project files cannot be imported directly.
- 3rdparty candidates: Schneider Lexium 28, B&R ACOPOSmicro, Siemens S210.
Critical note: Original motor uses EnDat 2.2 encoder. New drive must support EnDat interface to reuse existing motor.
Selection Pitfall Warnings
- ❌ Never replace CDE32 (230 V class) with CDE34 (400 V class); voltage mismatch will destroy motor.
- ❌ Suffix C2.4 denotes EnDat hardware; cannot directly substitute C1.x (TTL incremental encoder) variants; encoder hardware is incompatible.
- Legacy DriveManager project files cannot be imported into KEBA KeDrive; full retuning mandatory.
- TypicalApplication Fields
Maquinaria textil, maquinas de imprimir, equipo de embalaje
Auxiliary axes for machinetools, positioning tables
Woodworking machinery; mostly found on legacy imported equipment.

Compatible Original LUST Synchronous ServoMotors
Drive hardware: C2 = EnDat 2.2 absolute encoder interface; drive continuous 3 A, peak 6 A; 3×230 V AC supply.
Hard constraints: Motor must be 230 V winding synchronous servo with EnDat 2.2 (singleturn / multiturn). Motor continuous current ≤ 3 A, peak ≤ 6 A. Rango de potencia: 0.250.75 kilovatios. 400 Vwinding motors are not supported. TTL incrementalencoder motors (for C1hardware drives) cannot operate directly with this unit.
Original motor families LS, LSM, LSML (LUJURIA / LTI) are all EOL. Only used / refurbished units available.
- OEM Compatible Motor List (EnDat 2.2, 230 V)
| Modelo de motor | Potencia nominal | Par nominal | Velocidad nominal | Corriente nominal | Observaciones |
| LS‑07‑030‑2N‑000 | 250 W. | 0.8 Nuevo Méjico | 3000 rpm | 1.4 A | Small flange, no brake, EnDat 2.2 |
| LS‑07‑050‑2N‑000 | 400 W. | 1.27 Nuevo Méjico | 3000 rpm | 2.1 A | No‑brake; brake variant suffix‑B000 |
| LS‑08‑075‑2N‑000 | 750 W. | 2.39 Nuevo Méjico | 3000 rpm | 2.8 A | Maximum compatible power. Continuous operation at full load not permitted; reducción requerida. |
| LSML‑07‑030‑4N‑000 | 250 W. | 0.8 Nuevo Méjico | 4500 rpm | 1.5 A | High‑speed low‑inertia; for high‑speed axes in textile / embalaje |
| LSML‑07‑050‑4N‑000 | 400 W. | 1.27 Nuevo Méjico | 4500 rpm | 2.2 A | High‑speed no‑brake;‑B4N = 24 V holding brake |

Modelcode breakdown example `LS070502NB000`
- `LS`: standardinertia synchronous servo; `LSML`: lowinertia highspeed; `LSMM`: mediuminertia
- `07 / 08`: flange code (07 = 70 mm; 08 = 80 mm)
- `030 / 050 / 075`: power ×10 W (075 = 750 W)
- `2` = 3000 rpm; `4` = 4500 rpm
- `N` = EnDat 2.2 encoder; `I` = TTL incremental encoder (NOT for this drive)
- `B` = integrated 24 V holding brake; noB = brakeless.
- Electrical Boundary Conditions (Selection Hard Rules)
- Límite actual: Motor continuous RMS current ≤ 3 A; motor peak current ≤ 6 A. 750 W is upper power limit; avoid continuous fullload operation, apply derating.
- Encoder mandatory match: X7 hardware is EnDat 2.2. Motor encoder suffix must be2N /4N. Isuffix TTL incremental motors plugged into X7 trigger EPLS encoder failure.
- Winding voltage: Must be 230 V winding. 400 Vwinding motors strictly forbidden on CDE32; excitation cannot function correctly.
- Brake drive: Motorintegrated 24 V holding brake connects to X9. X9 requires independent external 24 V supply; drive does not source brake power. Cablebreak monitoring active.
- Motor temperature sensor: Onboard PTC thermistor may be connected for driveside monitoring, triggers EOTM motorovertemperature.
- 3rdParty Motor Compatibility Requirements
CDE32.003.C2.4 can drive 3rdparty permanentmagnet synchronous motors only if all conditions are satisfied:
- Motor winding 3×230 V AC; continuous phase current ≤ 3 A.
- Comentario: Heidenhain EnDat 2.2, DSub15 pinout matching LUST cable specification.
- All motor parameters must be manually entered in DriveManager: stator resistance, d/qaxis inductance, polepair count, continuo / peak current, backEMF Ke. No preloaded motor database; no autorecognition.
⚠️ Risk: Incorrect tuning of 3rdparty motors leads to EOC overcurrent, axis oscillation or poor positioning accuracy. Prefer original LS / LSML series motors.
- Common MismatchRelated Faults
| Código de falla | Fenómeno | Causa principal |
| E‑PLS | Encoder alarm | Motor fitted with TTL‑I instead of EnDat‑N; daño del cable; pin‑out mismatch |
| E‑OC on enable | Immediate over‑current upon enable | 400 V‑winding motor connected; motor winding short‑circuit; wrong pole‑pair / inductance parameters |
| E‑OTM motor over‑temp alarm | Motor physically cool | PTC thermistor wiring missing; motor mechanical overload |
| Insufficient torque / low maximum speed | Motor rated‑current exceeds drive 3 A rating; wrong back‑EMF setting |
- MotorDrive System Upgrade Paths (when original motor fails)
- Repair route: Source used LSxxxxx2N /4N motor. Verify EnDat 2.2 encoder health, check ratedcurrent, retune via DriveManager.
- Fullsystem replacement route: KEBA KeDrive D3 drive plus KEBA synchronousmotor; or 3rdparty servo. Match original mechanical flange and shaft dimensions.
Nota: Existing DriveManager motor parameters cannot be imported into new platform; full retuning is required.
- Associated Cabling
- Motor power cable: LUSTspec power cable U/V/W/PE including PTC temperature feedback conductors.
- Encoder cable: Doubleshielded dedicated EnDat 2.2 DSub15 cable. Do NOT reuse TTL incremental encoder cables.
- Brake conductors integrated within power cable, routed to X9.

- HighFrequency Troubleshooting for CDE32.003.C2.4 (EnDat 2.2)
- EPLS (mostcommon fault)
Síntomas: Alarm at poweron OR random runtime trips.
Causas: Damaged X7 EnDat cable; bent DSub15 pins; TTLencoder motor connected to C2 hardware; encoder hardware failure; poor shieldearthing.
Prohibition: Never insert TTL incrementalencoder cables into EnDat port.
- EOC on enable
Verify motor winding is 230 V class (400 V windings forbidden). Check motorparameter entry (polepair count, stator d/q inductance).
- Frequent EOFF undervoltage trips
CDE32 requires full 3phase 230 V supply. Confirm L1L2L3 are all connected; no phaseloss.
- EOTM alarm while motor is physically cool
Check X2 PTC thermistor wiring. If motor has no PTC sensor, disable PTC monitoring in parameters.
- General FaultHandling Workflow
- Record panel fault code. If possible connect DriveManager and capture faultlog plus ERPAR subcode.
- Poweroff; disconnect motor powercable and encodercable to isolate whether fault originates from drive, cable or motor.
- Measure motor insulation resistance, PTC resistance, and brakeresistor ohmic value.
- Restore factory parameters; reload valid OEM motorparameterset; retune currentloop and speedloop.
- Hardwarerelated faults (ECPU, hardwaresubcode EOC): repair or replace drive unit.
