Description
ELAU MC-4/11/10/400 | 10A PacDrive M Servo Drive
Product Introduction
The ELAU MC-4/11/10/400 is a 10 A servo drive from the PacDrive M motion-control platform. It is designed for single-axis servo applications using a 380–480 VAC three-phase supply, with a 24 VDC control supply and SERCOS communication.
In legacy automated machinery, the MC-4/11/10/400 serves as the drive stage between the PacDrive motion controller and the connected servo motor. Its 10 A RMS rating and 25 A one-second peak-current capability distinguish it from lower-current MC-4 models. The 400 V designation is equally important: this unit is not an electrical substitute for the MC-4/11/05/230 or other 230 V variants.
For maintenance and procurement teams, the MC-4/11/10/400 may be relevant when restoring a PacDrive M axis or maintaining installed equipment. Before ordering, compare the complete model code, OEM order number, hardware revision, software version, and motor compatibility against the existing drive.

Global Sourcing & Live-Test SOP
For a legacy servo drive, the procurement risk is not limited to whether the unit powers up. Hardware revision, firmware, motor compatibility, and the condition of the power stage all matter.
Recommended incoming verification procedure:
- Nameplate inspection: Confirm MC-4/11/10/400 and OEM order number 13130247.
- Traceability capture: Record serial number, hardware revision, software version, and bootloader information where available.
- Physical inspection: Check the housing, power terminals, motor connector, SERCOS interface, and mounting points for damage or evidence of repair.
- Compatibility review: Compare the replacement against the installed drive and the machine’s electrical drawings, motor data, and PacDrive configuration.
- Controlled functional testing: If included in the supplier’s scope, use a compatible test setup to evaluate power-up behavior, diagnostics, and applicable drive functions.
- Test reporting: Document the test method, results, exceptions, and any functions not evaluated. A visual inspection alone is not a functional test.
- ESD-safe packing: Protect the drive in suitable ESD packaging with adequate cushioning for international transport.
Test-status disclosure: These are recommended procurement and inspection steps. They do not establish that the specific marketplace unit has been tested, repaired, or functionally validated.
Field Engineer’s Pitfall Guide
Warning 1 — Match the complete voltage and current variant.
The MC-4/11/10/400 is a 10 A, 400 V-class drive. Do not substitute a 230 V variant or a lower-current MC-4 based solely on the family designation or physical appearance.
Warning 2 — Hardware and software compatibility are mandatory checks.
ELAU’s MC-4 manual warns that exchanging drives with different hardware configurations or software versions can prevent accurate system operation. Capture the existing drive’s nameplate data and confirm compatibility before commissioning.
Warning 3 — Treat the DC circuit as hazardous after shutdown.
The drive’s DC circuit can retain dangerous voltage after mains power is removed. Follow the OEM discharge procedure and verify the safe voltage condition before touching terminals or removing the unit. Qualified personnel should perform installation and commissioning.
Frequently Asked Questions
Q1: What is the ELAU MC-4/11/10/400?
It is a 10 A RMS single-axis servo drive in the PacDrive M MC-4 family, designed for 380–480 VAC three-phase operation.
Q2: What is its OEM order number?
The documented order number is 13 13 02 47, commonly written as 13130247.
Q3: Can it replace an MC-4/11/03/400?
Not automatically. Although both are 400 V-class MC-4 drives, their current ratings differ. Confirm the machine’s drive configuration, motor requirements, and OEM compatibility guidance before substitution.
Q4: Does the MC-4/11/10/400 use SERCOS?
Yes. The MC-4 platform uses a SERCOS fiber-optic interface. Confirm the installed controller, network topology, and required optical connections.
Q5: Is the drive hot-swappable?
Do not assume hot-swap capability. Isolate the equipment, follow the OEM shutdown and DC-bus discharge instructions, and apply the machine’s lockout/tagout procedure before removal.
Q6: What information should be confirmed before purchase?
Verify the complete model code, order number, serial number, hardware revision, software version, motor compatibility, and supplier’s stated condition and test scope.
Q7: Does a surplus unit include a functional warranty?
Warranty coverage depends on the seller’s written terms. Confirm the return period, functional warranty, and whether a test report is included. Do not assume that used or surplus stock has been bench-tested.
