Why testing under power matters
A unit can pass a bench check with a multimeter and still fail the moment it drives a real load. That is why we test units the way they work in your machine: drives run a motor, and motors run under drive control.
1. Check-in: logged and photographed
When your unit arrives it is logged in our system, photographed and its condition recorded, including any wear and tear or physical damage. You always know what state it arrived in.
2. Free evaluation: finding the root cause
We power the unit up and test it to find out why it failed, not just what failed. You then get our findings and a written quote. No repair work starts until you approve it.
3. Component-level repair
We repair at component level: failed power devices, capacitors, supply circuits, connectors and other parts on the boards are replaced, rather than swapping whole modules. That keeps your part number, hardware and settings the same.
4. Testing on our own jigs
We have test jigs for most units, including Fanuc, Yaskawa, Siemens, Rexroth Indramat and Allen-Bradley, and we build custom jigs when a job needs one.
- Servo drives are tested with a motor, so the drive is proven under real current, not just powered on.
- Servo motors are tested under drive control, so we see how they actually run.
- Encoder alignment is checked on motors, because a misaligned encoder makes even a perfect motor fault. Why alignment matters.
5. Test report and warranty
Every repaired unit ships with a test report showing how it was tested, and is covered by our 12-month warranty. Typical turnaround is 24 to 72 hours once your quote is approved. Read our warranty.
