Description
The Schneider Electric ELAU MC-4/11/03/400 (Part Number: MC-41103400 / 13130252) is an intelligent, digital single-axis servo drive component belonging to the legacy PacDrive M motion control ecosystem. This hardware acts as an integrated system containing a mains input rectifier, a dynamic internal braking resistor, and a software-controlled power stage. Featuring a peak current rating of 3 A, this module is engineered for the precise control of small-to-medium fractional horsepower servo motors in high-speed packaging machinery, labeling applications, and specialized bottling lines.

Interface Layout & Network Synchronization
The MC-41103400 depends on a synchronized SERCOS ring topology to execute positioning profiles defined by a central master PacDrive controller (such as the MAx-4, C400, or C600).
Connection Configuration
All communication, power input, and motor termination terminals are assigned to fixed, standardized positions on the top and bottom of the drive’s chassis:
+-----------------------------------+
| ELAU MC-41103400 |
+-----------------------------------+
| [Tx] [Rx] -> SERCOS Fiber Optic |
| [X1] -> 24 V DC Control Power|
| [X2] -> Digital I/O / Probe |
+-----------------------------------+
| |
| Power Stage |
| |
+-----------------------------------+
| [X5] -> 3-Phase Mains Input |
| [X6] -> Motor Power Output |
| [X9] -> Encoder Feedback |
+-----------------------------------+ Digital Probe Capture
The drive includes hardware-level fast touch-probe digital inputs mapped to terminal connector X2. When an external registration mark or optical sensor triggers this circuit, the drive captures the absolute motor encoder position within less than 10 microseconds, making it suitable for high-accuracy cutting, indexing, and indexing-packaging procedures.
Commissioning & Legacy Migration Guidelines
When integrating a replacement MC-41103400 into an operational line, review these critical industrial field rules:
Engineering Note: Verify the hardware revision index and internal firmware baseline printed on the module side panel. If the replacement drive’s firmware version is incompatible with the machine’s compiled EPAS-4 system configuration, the SERCOS loop will generate an initialization error and fail to clear Phase 2.
- Fiber Optic Signal Integrity: When inserting the polymer optical fiber (POF) patch cables into the Tx and Rx sockets, ensure the locking collars click fully into place. Scratched, contaminated, or over-bent fiber ends attenuate light transmission, causing unrepeatable network synchronization drops (A\_S errors).
- Braking Resistor Considerations: While this 3 A variant features an internal braking resistor capable of handling low-inertia loads, rapid start-stop profiling of highly vertical or high-inertia axis components can saturate the internal thermal capacity. If overvoltage tracking faults (O\_V) occur consistently during deceleration, an auxiliary external resistor must be added across the DC bus.
- 24 V DC Control Power Sequencing: Ensure the external 24 V DC control voltage is applied to terminal X1 and fully stabilized before switching on the primary 3-phase high-voltage grid line. This sequencing allows the logic board to successfully boot and parse safety interlocks prior to power stage energization.
Frequently Asked Questions
What does the “11/03/400” suffix stand for?
Per ELAU’s technical designation standards: 11 represents the nominal internal design standard variation, 03 specifies the maximum peak output current capability (3 A RMS), and 400 indicates that the power hardware is rated for global 3-phase mains networks up to 480 V AC.
Can the MC-41103400 drive be used with non-ELAU servo motors?
The drive is optimized to read the electronic nameplate data embedded within ELAU SM-series synchronous servo motors natively. While it can theoretically control third-party permanent magnet synchronous motors, configuring the correct commutation alignment, winding inductance parameters, and feedback scaling requires complex manual tuning profiles within the legacy EPAS programming utility.
What is the current upgrade path if the MC-4 series becomes unavailable?
The ELAU PacDrive M series is a mature platform. For complete lifecycle retrofits, Schneider Electric recommends migrating the drive and its host controller over to the modern PacDrive 3 system architecture. In this scenario, the legacy MC-4 drives are typically engineered out and replaced with Lexium 52 or Lexium 62 cabinet-mounted servo drives.
