Remarques importantes

1. Cannot be directly replaced by Lexium28/32 or other newer Schneider servo drives

This is a dedicated PacDrive servo using the SERCOS bus. Its control architecture and communication protocol are completely different from general Lexium servo ranges. If the machine controller is PacDrive C400/C600, replacement is only possible with identical VDM series drives.

2. Directly interchangeable model: VDM01D10AA00 ↔ MC-4/11/10/400, fully hardware compatible.
3. Approvisionnement: Only available via automation spare parts suppliers (new surplus / used refurbished units); Schneider official has no stock and no further production.

1. BusErr ON steady: No SERCOS communication established with master
2. BusErr Flashing: Intermittent bus communication; câble / termination resistor issue
3. ERR ON steady: Critical internal hardware failure
4. ERR Flashing: Protection triggered during operation
5. Acceptance & Inspection Checklist for Second-hand VDM01D10AA00 Drives

⚠️ High Voltage Safety Rule: Après la mise hors tension, wait ≥10 minutes. Use multimeter to confirm DC bus voltage ＜50V before disassembly and measurement! Wear anti-static wrist strap.

Scène 1: Inspection statique (Power OFF – First step upon receipt)

1. Visual check of housing and connectors

Check casing for impact deformation, broken latches; confirm cooling vents are not blocked by oil/dust

Inspect power terminals L1/L2/L3, U/V/W, DC+/DCfor arcing, burn marks and discoloration

Check SERCOS fiber port, encoder socket, 24V control connector for bent, oxidized or recessed pins

2. Internal visual inspection (if disassembly is permitted)

Check PCB for water stains, corrosion, mold, burnt or exploded components

Inspect DC bus electrolytic capacitors: bulging or electrolyte leakage (common aging issue for legacy ELAU drives)

Check IGBT power module and driver board for rework solder joints; beware refurbished repaired units

3. Multimeter static measurement (Diode Test Mode)

Measure voltage drop between U/V/W and DC+, DC-; readings for three phases must be balanced with deviation ＜0.1V

U/V/W to PE protective earth must show infinite resistance; low resistance = IGBT earth breakdown → reject unit

Rectifier bridge readings on L1/L2/L3 must be balanced; abnormal reading on any phase indicates rectifier damage

Scène 2: Low Voltage Pre-power Test (24V control power ONLY, NO motor connection)

1. Connect only 24VDC control supply; do NOT connect 380V main power or motor
2. Observe power-up sequence:

Self-test completes without immediate critical hardware alarms such as 114,115

BusErr LED lights up (normal without SERCOS master station); ERR LED must NOT stay permanently ON

✘ If ERR is steady ON immediately after 24V power-up: internal hardware fault, reject unit

3. Record startup status; check for abnormal noise or burning smell

Scène 3: Full Functional Powered Test (PacDrive C400/C600 Controller Required)

Critical limitation: General servo testers cannot communicate or test ELAU VDM drives due to proprietary SERCOS II protocol.

1. Connect 380V three-phase mains, SERCOS bus and matching ELAU SH/SM servo motor
2. Scan drive via EPAS-4 software on controller:

Controller can correctly identify model VDM01D10AA00 and read serial number

No Fault 114 EEPROM error (permanent hardware failure, cannot be fixed)

3. Basic function verification

Drive parameters can be uploaded and downloaded; motor parameters can be loaded successfully

Servo enable, opération de jogging; motor runs smoothly without vibration or abnormal noise

Continuous no-load operation for 30 minutes; monitor drive temperature, no random fault trips

4. Stress cycling test

Repeatd start/stop and forward/reverse operation; detect intermittent encoder or overcurrent faults caused by poor solder joints

Scène 4: Red Flags – Do NOT purchase if any condition exists

1. Imbalanced IGBT readings or U/V/W short to earth during static measurement
2. ERR LED steady ON after 24V control power-up
3. Fault code 114 EEPROM error detected by controller
4. PCB water damage, heavy corrosion, extensive rework wiring or full capacitor replacement
5. Faults only occur after warm-up under load (typical symptom of dry joints or degraded capacitors)

Additional Practical Tips

1. VDM01D10AA00 ↔ MC-4/11/10/400 are hardware interchangeable; however firmware version should match existing drives on machine to avoid compatibility issues.
2. Do NOT attempt testing with standard general servo testers; SERCOS II protocol does not support pulse command or EtherCAT.
3. Common seller trick: Only provide 24V power-up photos (no ERR light), without video of operation under main power + moteur. Such units often have hidden faults triggered only under load.

Full Inspection Standard for Second-hand ELAU VDM01D10AA00 (MC-4/11/10/400)

Condition préalable importante: This drive uses dedicated SERCOS II bus. General servo testers are incompatible. Testing requires PacDrive C400/C600 controller + EPAS4 software. After power cut, wait 10 minutes minimum to discharge DC bus capacitors; wear anti-static wristband.

1. Static Power-off Inspection (Visual + Multimètre)

1.1 External Visual Check

1. Check housing for impact cracks; cooling vents free from oil and dust blockage.
2. Power terminals L1/L2/L3, U/V/W, DC+/DC-: check for arcing burn marks and melted terminals.
3. Connecteurs: SERCOS fiber port, encoder socket, 24V control plug; inspect pins for oxidation, bending and pin retraction.
4. Nameplate: Confirm clear model VDM01D10AA00 and serial number; watch out for re-stick counterfeit labels.

1.2 Internal Visual Inspection (Recommended if disassembly allowed)

1. PCB board: No water marks, corrosion spots, mold; no burnt or ruptured components.
2. DC bus electrolytic capacitors: Check for bulging casings and electrolyte leakage (top aging failure mode for ELAU legacy drives).
3. Rework traces: Check IGBT driver board and main control board for extensive re-soldering or jumper wires; heavily repaired drives have poor long-term stability.
4. Internal flat cables: Check connectors for looseness and oxidation.

1.3 Multimeter Diode Test for Power Circuit Screening【Critical IGBT Breakdown Test】

Terminals under test: L1/L2/L3 (saisir), U/V/W (motor output), CC+, CC-

1. Rectifier bridge test: Balanced forward voltage drop from L1/L2/L3 to DC+ and DC-, phase deviation ＜0.1V; abnormal reading indicates rectifier damage.
2. IGBT inverter test: Balanced voltage drop from U/V/W to DC+ and DC-.
3. Essai d'isolation: Infinite resistance between U/V/W and PE protective earth;

✅ Low resistance reading → IGBT breakdown, reject unit immediately.

Passing static measurement only confirms power module is not shorted. It cannot verify proper operation of gate drive circuits.

2. Low Voltage Standalone Power Test (24V control supply only, NO 380V mains / NO motor)
3. Apply 24VDC control power and observe LED status:

✅ Normal status: BusErr LED ON (expected without SERCOS master); ERR fault LED must NOT stay ON continuously

❌ Critical defect: ERR steady ON after power-up → Main control hardware failure (EEPROM / gate drive power supply damage, rarely repairable)

2. Listen for abnormal buzzing noise or burning odor.

Passing this stage only confirms basic control board power supply; power circuit functionality remains unvalidated.

3. Full Powered Functional Test (380V Supply + PacDrive Controller + ELAU Servo Motor + EPAS4 Software)

3.1 SERCOS Bus Identification Test

1. Switch on three-phase mains and SERCOS fiber bus; perform bus scan via software.
2. ✅ Pass: Controller identifies drive model VDM01D10AA00, serial number and firmware revision.
3. ❌ Fail: Cannot be scanned or frequent disconnection → SERCOS interface damage; Fault code 114 (EEPROM error) = permanent failure, discard unit.

3.2 Parameter Read/Write & Motor Matching Test

1. Drive parameters and motor data can be uploaded and downloaded normally.
2. Load corresponding SH/SM motor parameters without 138 Prohibited motor alarm.

3.3 No-load Operation Test

1. Enable servo, execute jog command; motor runs smoothly without vibration, squealing or abnormal noise.
2. Continuous no-load operation for 30 minutes with monitoring:

No random fault trips (surintensité, encoder error, échec de communication);

Stable casing temperature without excessive overheating.

3.4 Dynamic Stress Test (Detect hidden dry joints and capacitor degradation)

1. Continuous start-stop and forward/reverse cycling.
2. Apply simulated shock load if possible.

Key observation: Check if faults appear after thermal stabilization (typical characteristic of dry solder joints or degraded capacitance).

4. Purchase Risk Criterion – Reject unit if any item applies
5. Unbalanced U/V/W diode readings or motor output short to earth during static measurement
6. ERR LED steady ON after 24V control power-up
7. Fault code 114 EEPROM read error detected by controller
8. Intermittent faults (107 surintensité, 118 encoder error, 115 gate power fault) after drive heats up
9. PCB water corrosion, extensive component replacement and rework
10. Supplier can only provide 24V power-up footage, cannot supply video of operation under 380V mains + moteur (common market fraud practice)
11. Approvisionnement & Site Acceptance Additional Guidance
12. Firmware Version Matching: Match firmware revision to existing drives installed on machine to avoid abnormal operation. VDM01D10AA00 and MC-4/11/10/400 share hardware compatibility, but firmware mismatch may cause unexpected behavior.
13. Risk without original C400/C600 controller:

No universal servo tester can fully validate this drive. Static measurement alone carries undetected fault risk. Request warranty support from vendor.

3. Brake circuit verification: Run extended deceleration cycles to confirm no Fault 113 (Bleeder defective), as internal braking transistor failure is a common hidden defect.

Simplified Acceptance Checklist (Can be sent directly to vendors)

1. Photo evidence of 24V power-up LED status;
2. Screenshot showing controller successfully recognizes drive model under 380V mains power;
3. Video of continuous motor jogging and forward/reverse operation;
4. Supplier warranty commitment: No IGBT breakdown, no EEPROM hardware failure, support on-site power-up inspection after delivery.
