Description
ELAU MC-4/11/03/400 | 3 A PacDrive Servo Drive
Product Overview
When a legacy PacDrive machine loses a servo axis, the replacement drive must match more than the motor’s current rating. Control architecture, feedback compatibility, firmware, and communication configuration all affect whether the machine can return to service without additional integration work.
The ELAU MC-4/11/03/400 is a PacDrive M digital servo drive rated for 3 A RMS motor current at 8 kHz, with a 7.5 A RMS peak rating for 1 second. It connects to a compatible PacDrive controller through SERCOS fiber-optic communication and is designed for coordinated servo applications.
This model is distinct from the MC-4/11/01/400, which is a lower-current variant. Although the two drives share the MC-4 family, their power ratings differ. For replacement procurement, verify the full model and OEM order number, then confirm the drive’s compatibility with the installed motor, feedback system, and machine configuration.

Global Sourcing & Live-Test SOP
The following is a recommended inspection procedure for the ELAU MC-4/11/03/400. It does not represent testing performed on the specific marketplace unit.
Inbound Verification
- Photograph the complete drive, nameplate, connectors, terminals, and enclosure.
- Confirm MC-4/11/03/400 and OEM order number 13130245.
- Inspect for corrosion, impact damage, damaged terminals, and signs of unauthorized repair.
- Check that covers and connector components are present.
Serial and Traceability Review
- Record serial number, hardware revision, firmware version, and date code where available.
- Request actual-unit photographs and a written condition classification.
- Distinguish new old stock, used, repaired, and refurbished inventory.
- Obtain warranty and return terms before purchase.
Compatibility and Powered Testing
- Verify mains and control-supply requirements against OEM documentation.
- Confirm motor ratings, feedback type, SERCOS topology, and controller compatibility.
- Test only on an approved MC-4 setup with qualified personnel.
- Check startup diagnostics, communication, and supported drive functions.
- Do not connect the unit to production machinery until configuration and compatibility are established.
Diagnostics and Test Reporting
- Record test conditions, equipment used, and diagnostic results.
- Document which functions and interfaces were actually tested.
- Identify any untested functions or restrictions.
- Do not represent visual inspection or basic power-up as a complete functional test.
ESD-Safe Shipment
- Use suitable ESD protection.
- Protect terminals and connectors against impact and contamination.
- Secure the drive against movement during transit.
- Include the inspection report and exact model/order number with the shipment.
Field Engineer’s Pitfall Guide
1. Do not substitute the 1.5 A variant based on family designation alone.
The MC-4/11/03/400 is rated at 3 A RMS, while the MC-4/11/01/400 is a lower-current model. Confirm the original drive’s complete designation and motor requirements before approving a substitute.
2. Match motor feedback and controller configuration.
A matching current rating does not guarantee that the drive will support the installed motor or feedback arrangement. Confirm the motor type, feedback system, firmware, and SERCOS configuration before commissioning.
3. Observe high-voltage isolation and discharge procedures.
The drive’s DC bus operates at hazardous voltage and may retain energy after mains power is removed. Follow the OEM shutdown and discharge procedure, and verify safe conditions before handling terminals or replacing the unit.
Frequently Asked Questions
Q1: What is the ELAU MC-4/11/03/400?
It is a PacDrive M digital servo drive designed to control a compatible servo motor in an industrial motion-control system.
Q2: What is the OEM order number?
The documented order number is 13 13 02 45, commonly written as 13130245.
Q3: What is the rated motor current?
The drive is rated for 3 A RMS at 8 kHz, with a peak current of 7.5 A RMS for 1 second.
Q4: What power supply does it require?
The specified mains input is 3-phase 380–480 VAC, with a 24 VDC control supply. Verify terminal assignments and ratings against the applicable documentation.
Q5: Does the MC-4/11/03/400 use SERCOS?
Yes. The MC-4 platform uses a SERCOS fiber-optic interface to communicate with a compatible PacDrive controller.
Q6: Can it replace the MC-4/11/01/400?
Do not assume direct interchangeability. The /03 model has a higher current rating than the /01 variant. Confirm the machine’s drive configuration, motor, and OEM-approved substitution options.
Q7: What should buyers verify before ordering?
Confirm the full model and order number, nameplate details, hardware and firmware revision, motor compatibility, condition classification, available test records, warranty, and return terms.
