4. Product Introduction
The ELAU MC-4/11/05/230 (order number 13130246, also listed as MC-41105230) is a single-axis digital servo amplifier in the PacDrive MC-4 family. It combines the mains supply unit, power stage, and software regulator in one compact housing and links to the PacDrive controller exclusively via SERCOS fiber-optic cable. The unit is rated for 220–240 VAC single- or three-phase supply and delivers 5 A continuous / 12.5 A peak for one second.
This drive is commonly found on packaging, converting, and material-handling machines that require precise single-axis position, speed, or torque control. Automatic motor recognition via the electronic nameplate and 250 % overload capability make it a direct fit for existing PacDrive installations running firmware V00.22.XX. The series is obsolete, so verified New Surplus or tested units are the practical replacement option.
5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No LEDs / no power-up | Missing 24 VDC control or mains | ❌ Low | Measure 24 VDC at control terminals and 220–240 VAC at L1/L2 (or L1/N) | Verify PSU, fuses, and single-/three-phase wiring first |
| SERCOS communication timeout | Fiber cable fault or node mismatch | ✅ High | Inspect fiber connectors and status LEDs on controller and drive | Clean fiber ends; confirm node address and firmware |
| “Impermissible motor” fault | Motor type or firmware mismatch | ✅ High | Compare motor nameplate against drive firmware V00.22.XX | Use only approved motors; match firmware version |
| Overvoltage / bleeder fault | Excessive regenerative energy | ✅ Medium | Monitor DC bus voltage; check external resistor if fitted | Verify or add external braking resistor; slow deceleration |
| Overtemperature | Restricted airflow or ambient >45 °C | ✅ Medium | Check cabinet temperature and cooling path | Improve ventilation or derate load |
| Inverter Enable not active | Safety circuit open | ❌ Low | Measure Enable input (20–30 VDC) | Check safety wiring and interlocks |
If the fault remains after these checks, provide clear photos of the type plate, diagnostic buffer extract, and fiber status LEDs to technical support.

6. Frequently Asked Questions (FAQ)
Q: Is the MC-4/11/05/230 still in production?
A: No. The PacDrive MC-4 series was discontinued. Available units are New Surplus or professionally tested stock. Quantities are limited.
Q: Can I hot-swap this drive?
A: No. Power down the axis group completely and allow the DC bus to discharge before replacement. Hot-swapping can damage the fiber link or power stage.
Q: Does the configuration stay when I replace the unit?
A: Motor parameters are read from the electronic nameplate. Axis parameters and SERCOS node address reside in the PacDrive controller project. Download the matching project or set the identical node address before power-up.
Q: What supply voltage does this model accept?
A: 220–240 VAC, single-phase or three-phase. Connecting a 380–480 V supply will destroy the unit. Always verify the type plate before wiring.
Q: Why is a New Surplus unit priced lower than the old factory list?
A: The model is obsolete. Remaining original New Surplus inventory is offered below historical list price while still being genuine OEM product.
Q: What firmware should I request?
A: Most field units run V00.22.XX. Note the firmware of the drive being replaced and request the same range. Firmware mismatch can cause communication or motor recognition faults.
Q: Do you provide test documentation?
A: Yes. Every unit ships with a functional test report covering power-up, SERCOS handshake, current delivery under load, and insulation resistance. Photos and test video are available on request.
