A customer purchased what he thought were genuine XtraDrive XD-01-MSD0 drives from an Asian seller. The price was high, the trust was strong, and the units looked authentic.

However, the drives were never tested upon arrival. They remained in storage for months until a machine failure revealed the truth: the purchased units were fake conversions of 100-watt Yaskawa servos from a different series.

Externally identical and connector-compatible, internally manipulated but useless. The control boards had been tampered with, yet the drives never functioned.

The result: total failure, high financial loss, no refund possible as the eBay return period had expired.

Such cases are increasingly common. Many sellers register accounts in Europe while shipping from China. Customers feel safe when devices look “new”

but often they are just cosmetically refurbished or plain counterfeits.

Our approach:

• Opened and analyzed the fake units: immediately visible mismatches in power and control sections.
• Created documentation with photos for the customer.
• Received the customer’s original defective drives, which we repaired.
• Preventive replacement of critical components (capacitors, optocouplers, power modules).
• Tested on original test bench with thermal load monitoring.

Testing procedures:

• 100% load endurance test for several hours.
• Oscilloscope monitoring of signals.
• Thermal monitoring of heatsink and PSU.

In the end, the repaired genuine units were returned to the customer fully functional, documented, and verified.

Had the fakes been used longer, the customer would have faced extended downtime, machine shutdown, and massive follow-up costs.

Preventive Measures for the Customer

• Test devices immediately upon delivery, do not store them untested.
• Perform regular cleaning and inspection.
• Replace fans and seals proactively.
• Conduct insulation testing on motors and cabling.
• Regularly check connectors as vibration can cause wear.
• Maintenance intervals: inspection every 12–18 months, preventive overhaul every 3–5 years.

Conclusion

This case clearly shows: cheap counterfeits are a dangerous trap.
Only tested repairs and original parts ensure operational reliability. Preventive maintenance not only saves costs but also protects the entire machine from unexpected breakdowns.
