Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No power / blank display | Missing 380-480VAC input or blown fuse | ✅ High | Measure 3-phase voltage at input terminals; check fuses | Verify input power first; replace fuse if blown and retest |
| Overcurrent fault (OC) | Motor short circuit or overload | ✅ High | Measure motor winding resistance; check for ground fault | Check motor and cables first; replace drive if motor is OK |
| Overvoltage fault (OV) | Regenerative energy too high or braking resistor fault | ✅ High | Check braking resistor connection; measure DC bus voltage | Install/replace braking resistor; reduce acceleration rate |
| Undervoltage fault (UV) | Input voltage too low or phase loss | ✅ High | Measure all 3 phases; check for phase imbalance >10% | Correct input power; replace input reactor if needed |
| Motor overheating | Excessive load or cooling fan failure | ✅ Medium | Check motor temperature; verify fan operation | Reduce load or improve cooling; replace motor fan if failed |
| Communications error | Missing 24VDC control power or bus fault | ✅ High | Measure 24VDC at control terminals; check bus wiring | Verify control power; check fieldbus config and wiring |
| Following error / position error | Wrong encoder feedback or gain mismatch | ✅ High | Check encoder connection; read actual vs commanded position | Verify encoder wiring; retune servo gains |
| Drive won’t enable | Safety circuit open or enable signal missing | ✅ High | Check enable input signal; verify safety relay closed | Close safety circuit; verify 24VDC enable signal present |

Frequently Asked Questions
Q: Is the ELAU MC-4/11/03/400 still in production?
A: This is legacy PacDrive hardware. Stock is typically new surplus or refurbished inventory. ELAU motion control products are now under Schneider Electric. Verify current availability with suppliers before ordering.
Q: What does this drive do?
A: It is a single-axis servo amplifier for the ELAU PacDrive system. It controls servo motors in packaging machines, blister packing equipment, and other industrial automation applications requiring precise motion control.
Q: What voltage does it require?
A: It requires 380-480VAC 3-phase input at 50/60Hz. Control voltage is 24VDC at 1A. Make sure your site power matches these requirements before ordering.
Q: Can I use this with any servo motor?
A: It supports ELAU PacDrive servo motors with automatic motor recognition. For non-ELAU motors, verify encoder compatibility and motor parameters. The drive outputs 0-480VAC at 0-600Hz.
Q: How many axes can one PacDrive controller handle?
A: Up to 40 servo axes can be connected to one PacDrive Controller. The MC-4/11/03/400 is a single-axis module, so you need one drive per axis.
Q: Is this drive hot-swappable?
A: No. Always power down the drive before installation or removal. Hot-swapping can damage the backplane, motor, or drive electronics.
Q: What’s the difference between new surplus and refurbished?
A: New surplus is unused original inventory with 1-year warranty. Refurbished units are tested/recertified with a standard 2-year warranty. Refurbished units are more sustainable and cost-effective.
Q: Why is this cheaper than buying new from Schneider?
A: This is legacy hardware available as new surplus or refurbished inventory, not current OEM production. The lower price reflects limited availability, not a different operating principle.
Q: What should I check before ordering?
A: Confirm the exact part number (MC-4/11/03/400), verify your supply voltage (380-480VAC 3-phase), check your motor type (ELAU PacDrive recommended), and confirm the condition (new surplus vs refurbished). Also verify the warranty terms (1 year vs 2 years) and whether you need exchange service availability.
