Most Common Faults We Can Solve
These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.
- UnderVoltage: DC bus dropped below the minimum threshold.
Fix: Check incoming AC for sags/interruption; we test input and DC bus health and stabilize with line conditioning if needed.
- SW OverCurrent: 1 ms current exceeded its rating (above cont., below HW limit).
Fix: Reduce load/boost/brake volts; we capture waveforms and reset to safe values.
- OverVoltage: DC bus voltage exceeded the maximum value.
Fix: Verify line transients; extend decel time or add a dynamic brake option; we can size/install a DB kit and soak-test the drive.
- Transistor OverTemp: Power devices exceeded safe temperature.
Fix: Same as above—cooling & load audit; we replace failed fans/IGBTs and test.
- Heatsink OverTemp: Heatsink temperature above limit (or very low).
Fix: Verify ambient, fan operation, and load; we replace fans and clean/recertify cooling path.
- Drive OverLoad: 110% for 1 min or 150% for 3 s exceeded.
Fix: Reduce load or increase accel time; we profile current vs. cycle and tune ramps.
- Load Loss: Torque current below [Load Loss Level] for set time.
Fix: Verify mechanical coupling; we check level/time and drive feedback.
