Product Introduction

A packaging machine can lose its entire coordinated motion sequence when the central motion controller fails. The ELAU C400/10/1/1/1/00 is a PacDrive C400 controller that integrates PLC logic and servo-motion coordination into one control platform.

Within the PacDrive architecture, the C400 acts as the central controller for SERCOS-connected servo drives and machine functions. The documented C400 configuration uses a 600 MHz Intel Pentium M processor, 256 MB RAM, and support for up to 16 SERCOS slaves (the exact machine configuration should always be checked against the installed project).

The unit is particularly relevant to legacy packaging and machine-automation equipment where replacing the complete motion platform would involve extensive software migration and commissioning work.

Application Scenarios & Pain Points

On high-speed packaging lines, the C400 coordinates machine logic and synchronized servo movements, making controller availability important when production depends on tightly timed axis sequences.

For filling and processing machinery, a failed controller can interrupt multiple servo axes at once rather than affecting a single drive.

In printing and converting equipment, maintaining the original PacDrive controller can avoid extensive changes to established motion programs and SERCOS configurations.

With the original C400 operational, the machine retains its established controller-to-servo architecture. Without a compatible replacement, commissioning a substitute platform can require software conversion, I/O remapping, and motion revalidation.

In cabinets exposed to 50°C+ ambient conditions, thermal management deserves particular attention because controller electronics, storage media, and power supplies can experience accelerated aging.

? Common Error Codes & Diagnostic Symptoms

Symptom/Code: Error 502 / SERCOS Loop Not Closed
→ Diagnosis: The controller cannot establish the expected SERCOS communication loop, potentially due to a failed controller interface, drive, fiber connection, or network configuration.
→ Action: Check the SERCOS path and connected drives first; replace the C400 if the controller interface is confirmed defective.

Symptom/Code: Controller Fails to Complete Startup / Diagnostic Fault
→ Diagnosis: A controller hardware, memory, storage, or power-related fault can prevent normal initialization.
→ Action: Verify 24 VDC supply and diagnostics, then replace the controller if hardware failure is confirmed.

Symptom/Code: Multiple Servo Axes Offline
→ Diagnosis: Simultaneous loss of several SERCOS-connected axes can indicate a central controller or SERCOS communication fault rather than individual servo-drive failures.
→ Action: Check controller diagnostics and SERCOS status before replacing individual drives.

Cross-Reference & Lifecycle Migration

• Primary Model: C400/10/1/1/1/00
• Alternate Catalog Reference: C4001011100.
• Manufacturer Reference: 13130261 is associated with this C400 configuration in technical and supplier records.
• Platform: ELAU PacDrive C400.
• Compatibility: Verify the installed machine project, SERCOS topology, connected MC-series drives, I/O configuration, and software version before substitution.
• Firmware/Project Requirement: A hardware swap may require the appropriate application project or configuration to be restored. Do not assume that installing a replacement unit automatically restores the machine program.
• Lifecycle Status: Legacy / Limited
  • The C400 is an older PacDrive platform, so maintaining a tested spare can be important for machines that cannot yet be migrated.
  • Schneider Electric now owns the ELAU product portfolio, while secondary-market suppliers continue to support discontinued C400 hardware.

Important: Do not treat VCA07AAAA0AA00 as an interchangeable identification without verifying the physical nameplate and machine documentation; supplier databases associate this code with the C400/10/1/1/1/00, but part-number records are not always consistent across distributors.

Field Engineer’s Tech Notes (Anti-Pitfall Guide)

1. Do not confuse the C400 with a standalone servo amplifier.
   The C400 is the central PLC/motion controller. The actual servo power stage is provided by the connected PacDrive drive hardware. Treating the controller as a drive can lead to incorrect replacement selection.
2. Back up the machine project before removing the controller.
   A replacement controller may require restoration of the correct application program, parameters, and motion configuration. Hardware matching alone does not guarantee that the machine will restart correctly.

Strict QA & Testing SOP

A proper inspection procedure for the ELAU C400/10/1/1/1/00 should include:

1. Inbound Identification
   • Verify the complete model number.
   • Compare the nameplate and manufacturer markings with the purchase requirement.
   • Record serial and hardware revision information.
2. Physical Inspection
   • Inspect the housing, connectors, display, mounting points, and cooling areas.
   • Check for corrosion, impact damage, or overheating.
3. Power-Up Verification
   • Apply the specified 24 VDC supply in a controlled test environment.
   • Confirm startup behavior and diagnostic indications.
4. Controller Diagnostics
   • Verify processor operation.
   • Check diagnostic display and status indicators.
   • Confirm communication interfaces.
5. SERCOS Testing
   • Connect the controller to a compatible test configuration.
   • Verify SERCOS initialization and communication with representative drive hardware.
6. Functional Testing
   • Confirm controller communication and motion-control functions.
   • Verify stable operation under sustained test conditions.
7. Final Packaging
   • Use ESD-safe packaging.
   • Protect connectors and the controller housing against shock and moisture during international transportation.

Test videos and inspection records can be provided with the unit upon request.

Buyer’s FAQ

Q1: Is the C400/10/1/1/1/00 a PLC or a servo drive?

It is a PacDrive motion controller/PLC, not the individual servo amplifier. It coordinates machine logic and motion through the PacDrive architecture and SERCOS-connected drives.

Q2: Can I simply install another C400 and start the machine?

Not necessarily. The replacement must match the machine architecture, and the appropriate application project, parameters, and motion configuration may need to be restored.

Q3: What does the “10” configuration indicate?

The C400/10 configuration is the C400 version documented for systems supporting up to 16 SERCOS slaves. The technical manual distinguishes it from the C400/A8 configuration for up to eight SERCOS slaves.

Q4: Is this a good item to keep as a spare?

For a production machine still dependent on the legacy PacDrive C400 platform, yes. Because the platform is legacy, a tested spare can reduce the risk of extended downtime while a complete control-system migration is planned.
