Dynamic Load Testing for Guaranteed Reliability
A drive repair isn't complete until it's been tested with a motor under a dynamic load. Our custom-built load centers allow us to simulate your real-world application, ensuring your drive will perform flawlessly once it's re-installed in your facility.
- Full-Horsepower Load Centers: Our load centers allow us to test repaired drives under full power and load conditions to verify performance.
- OEM Parameter Reset: We reset all drives to factory default parameters, ensuring a clean slate for your specific application's programming.
Our Drive Repair Process
Static & Dynamic Evaluation
We perform initial diagnostics and power up the unit to identify all faults in the power and control sections.
Component-Level Repair
Failed components are replaced, preventative maintenance is performed on high-failure parts, and the unit is cleaned.
Dynamic Load Testing
The drive is connected to a matching motor and runs under load for an extended period to ensure total reliability.
