Description
ELAU MC-4/11/01/400 | Single-Axis PacDrive Servo Drive
Product Overview
A failed servo drive can stop an entire machine axis, even when the controller, motor, and mechanical assembly remain serviceable. The ELAU MC-4/11/01/400 is a single-axis digital servo drive in the PacDrive M motion-control family. It provides the drive-side control and power stage required to operate a compatible servo motor within an integrated automation system.
The MC-4/11/01/400 is designed for use with a compatible PacDrive controller through a SERCOS interface. Its 1.5 A RMS current class and 380–480 VAC mains supply are key identification points, but they do not alone establish suitability for a particular motor or machine.
For maintenance procurement, match the complete model and material number against the installed unit. Confirm motor feedback, drive parameters, controller compatibility, and the original machine configuration before treating a replacement as ready for commissioning.

Global Sourcing & Live-Test SOP
The following is a recommended procurement and inspection procedure. It does not represent testing performed on a particular unit.
Inbound Verification
- Photograph the drive, nameplate, terminals, connectors, and enclosure.
- Confirm MC-4/11/01/400 and VDM01U15AA00 match the purchase order.
- Inspect for corrosion, impact damage, damaged terminals, and evidence of unauthorized repair.
- Check that covers and connector components are present.
Serial and Traceability Review
- Record serial number, hardware revision, date code, and supplier details 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
- Confirm mains and control-supply requirements against the OEM documentation.
- Verify motor ratings, feedback type, SERCOS topology, and controller compatibility.
- Use an approved MC-4 test setup and qualified personnel.
- Check startup diagnostics, communication, and supported drive functions.
- Do not connect the unit to production equipment until configuration and compatibility are established.
Diagnostics and Test Reporting
- Record test conditions, equipment used, and diagnostic results.
- Document which functions were actually tested.
- Identify untested interfaces or functions.
- 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/material number with the shipment.
Field Engineer’s Pitfall Guide
1. Do not confuse the MC-4 drive with a MAX-4 controller.
The MC-4/11/01/400 is a single-axis servo drive, not a multi-axis motion controller. Confirm the component’s role in the machine architecture before ordering.
2. Match the motor and feedback system—not just the current rating.
A 1.5 A RMS drive is not automatically compatible with every motor in that current range. Check motor electrical data, feedback type, and drive configuration against the OEM requirements.
3. Respect the high-voltage DC bus.
The drive’s DC bus can remain hazardous after mains power is removed. Follow the OEM isolation and discharge procedure, and verify the bus is safe before handling terminals or replacing the unit.
Frequently Asked Questions
Q1: What is the ELAU MC-4/11/01/400?
It is a PacDrive M single-axis digital servo drive used to control a compatible servo motor.
Q2: What is its associated material number?
The cross-reference is VDM01U15AA00. Confirm the full nameplate before placing an order.
Q3: What is the rated motor current?
The published rating is 1.5 A RMS at 8 kHz, with a 3.75 A RMS peak rating for 1 second.
Q4: What power supply does the MC-4/11/01/400 require?
The specified mains input is 3-phase 380–480 VAC, with a 24 VDC control supply. Verify terminal assignments and ratings using the applicable documentation.
Q5: Does this drive communicate through SERCOS?
Yes. The MC-4 platform uses a SERCOS fiber-optic interface to communicate with a compatible PacDrive controller.
Q6: Can this unit be hot-swapped?
Do not assume hot-swap capability. Follow the machine-specific shutdown and replacement procedure unless the OEM explicitly permits live replacement.
Q7: What should buyers verify before ordering?
Confirm the complete model and material number, nameplate details, hardware revision, condition, motor and feedback compatibility, available test records, warranty, and return terms.
