Description
ELAU MC-4/11/22/400 | 400V 15.2kVA Servo Drive
Product Introduction
The ELAU MC-4/11/22/400 is the high-current 22 A version of the PacDrive M MC-4 servo-drive family. It is designed for 400 V-class industrial motion systems and provides 22 A RMS continuous motor current at an 8 kHz switching rate, with up to 55 A RMS for a one-second peak-current interval. Its documented rated output is 15.2 kVA.
This model sits considerably higher in the MC-4 current range than the MC-4/11/10/400. That difference matters during replacement selection: current capacity, motor sizing, cabling, regeneration requirements, and the stored PacDrive configuration all need to match the machine application.
The /400 designation identifies the 380–480 VAC supply class. The MC-4/11/22/400 also uses a 530–680 VDC internal DC circuit and a substantial internal braking/bleeder system, making correct shutdown and DC-bus discharge procedures mandatory during maintenance.

Global Sourcing & Live-Test SOP
For a 22 A legacy servo drive, procurement inspection should go beyond checking whether the front panel looks clean. High-current power components, DC-bus capacitors, braking circuitry, and cooling hardware all deserve inspection.
Recommended incoming verification procedure:
- Nameplate verification
Confirm the complete designation MC-4/11/22/400 and OEM order number 13130254. - Traceability recording
Capture the serial number, hardware identification, software/firmware information, and revision markings before installation. - Power-stage inspection
Inspect the housing, terminals, fan, connectors, fiber-optic interfaces, and mounting hardware for damage, contamination, corrosion, or evidence of previous repair. - Electrical compatibility check
Confirm that the machine uses the correct 380–480 VAC supply class and that the connected motor and feedback arrangement are compatible with the drive configuration. - Controlled power-up test
If functional testing is part of the supplier’s service, use an appropriate test fixture and qualified personnel to evaluate power-up behavior, diagnostics, communication, and applicable drive functions. - Diagnostic review
Record active and stored diagnostic information where accessible. Pay particular attention to power-stage, temperature, braking, communication, and feedback-related faults. - Test-report documentation
Record exactly what was tested, what equipment was used, and which functions were not tested. A powered-on unit is not automatically a fully tested servo drive. - ESD-safe shipment
Package the drive in suitable ESD protection with mechanical cushioning. The fan, connectors, and terminal areas should be protected from impact during international transport.

Field Engineer’s Pitfall Guide
Warning 1 — Do not substitute by current rating alone.
The MC-4/11/22/400 is rated at 22 A RMS with a 55 A RMS one-second peak. Moving from a 10 A MC-4 to this unit—or the reverse—requires confirmation of the machine’s motor, drive configuration, cabling, protection, and control-system parameters. The physical fit of the enclosure is not sufficient evidence of compatibility.
Warning 2 — Verify the OEM order number carefully.
For this exact model, the ELAU documentation identifies 13 13 02 54 / 13130254. Some third-party marketplace and reseller pages publish other numbers against the same model. Use the actual nameplate and the OEM documentation as the procurement reference.
Warning 3 — The DC bus remains a serious maintenance hazard.
The documented DC circuit operates from approximately 530 to 680 VDC, with the internal bleeder operating around the specified voltage thresholds. Do not remove covers, disconnect motor wiring, or handle power terminals immediately after shutdown. Follow the OEM discharge procedure and verify the DC voltage with suitable measurement equipment before servicing.
Frequently Asked Questions
Q1: What is the ELAU MC-4/11/22/400?
It is a 22 A RMS single-axis servo drive in the PacDrive M MC-4 family, intended for 380–480 VAC three-phase applications.
Q2: What is the OEM order number?
The documented ELAU order number is 13 13 02 54, commonly written as 13130254.
Q3: What are the current and power ratings?
The drive is rated at 22 A RMS at 8 kHz, with 55 A RMS peak current for one second, and a documented rated output of 15.2 kVA.
Q4: Can it replace an MC-4/11/10/400?
Not automatically. Both are 400 V-class MC-4 drives, but the 22 A unit has substantially higher current capacity. Verify the motor, machine electrical design, controller configuration, and replacement requirements before substitution.
Q5: What communication system does it use?
The MC-4 platform uses a SERCOS fiber-optic interface. Confirm the existing PacDrive controller, SERCOS topology, optical connections, and stored configuration before commissioning.
Q6: Is the MC-4/11/22/400 hot-swappable?
Do not assume it is. Isolate the machine, follow the OEM shutdown and DC-bus discharge procedure, and apply the applicable lockout/tagout process before removing the drive.
Q7: What should be checked when buying a used unit?
At minimum, verify the complete model code, order number, serial number, hardware/software revision, physical condition, fan condition, connector condition, and seller’s functional-test and warranty terms.
Q8: Is this model still a current-production drive?
The MC-4 is a legacy PacDrive product family, so procurement should be handled as a lifecycle/obsolescence issue. Confirm current support and replacement strategy with the equipment OEM or Schneider Electric before designing a long-term maintenance program.
