Description
1. At-A-Glance Executive Brief
- Model / Catalog Number: C400A811100 (C400/A8/1/1/1/00)
- Brand: Elau / Schneider Electric (PacDrive M System)
- Part Type: Central Motion & Logic Controller / Servo Control Unit
- Lifecycle Status: Mature / Legacy Support Line (Widely deployed in packaging, handling, and converting machinery)
- Processor Architecture: Intel Pentium M 600 MHz (with 1 MB L2 Cache for up to 16 SERCOS slaves)
- Core Application: High-performance synchronized multi-axis motion control, PLC logic processing, and SERCOS ring communication management
2. Technical Introduction
A sudden controller failure or memory corruption on high-speed packaging or web-handling machinery can bring multi-axis production lines to an abrupt halt, risking expensive mechanical jams and extensive downtime.
The Elau / Schneider Electric C400A811100 (PacDrive C400/A8/1/1/1/00) is an advanced motion and logic controller designed to manage complex, multi-axis synchronized automation tasks. Powered by an Intel Pentium M 600 MHz processor and running a deterministic VxWorks real-time operating system, it integrates PLC functionality and motion control into a single unified hardware platform. Supporting up to 16 SERCOS interface drives, it delivers microsecond-level synchronization across high-speed servo loops. Deploying a verified original replacement controller restores precise machine kinematics and control logic without requiring application code rewrites.
Engineer’s Takeaway: Procuring an authentic Elau C400A811100 controller ensures absolute firmware compatibility, correct backplane slot positioning, and reliable optical SERCOS ring handshakes, preventing costly alignment errors during emergency line restorations.

4. Field Engineer’s Tech Notes
- CompactFlash and NVRAM Data Backup: Always back up the machine application project and system parameters from the CompactFlash card and NVRAM before swapping out a controller. The replacement unit must have its CompactFlash card configured or swapped with the original verified program to maintain machine calibration.
- SERCOS Fiber-Optic Handling: When disconnecting or reconnecting the SERCOS ring cables, maintain a clean optical interface free of dust and respect the minimum bend radius of the fiber-optic strands to prevent communication dropouts or jitter faults across connected servo drives.
5. Adaptive QA & Testing Protocol
Every unit undergoes rigorous bench validation prior to dispatch. For the Elau C400A811100 controller, our technicians mount the unit on a dedicated PacDrive test rack to verify CPU initialization, test 24VDC power rail stability under load, validate CompactFlash read/write execution, and check fiber-optic SERCOS communication loop integrity across multi-axis slave simulators. Functional test reports or pre-shipment video verification can be provided upon request.
6. Buyer’s FAQ
- Are these controllers supplied as New Surplus or refurbished?
We stock both factory-sealed New Surplus (NSFP) and fully bench-tested, static-safe operational refurbished units. Condition status is explicitly marked on every quote.
- What warranty coverage comes with this part?
All replacement Elau/Schneider automation hardware is backed by a standard 12-month operational warranty from the date of invoice.
- How fast can this controller ship to minimize plant downtime?
In-stock items ship same-day via priority air courier services to global destinations, mitigating critical path delays during emergency manufacturing shutdowns.
- Does the replacement unit require software reprogramming?
The C400A811100 serves as the hardware platform container. Providing your original CompactFlash memory card or downloading the compiled project file via EPAS-4 software ensures seamless restoration of your machine’s exact control sequences.
