Most Common Faults We Can Solve
These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.
- I/O Comm Loss: I/O board lost comms with MCB.
Fix: Check connectors/noise; we replace I/O board or MCB if needed.
- OverSpeed Limit: Speed correction exceeded [Overspeed Limit].
Fix: Remove overhauling load or raise limit; we re-tune slip/bus regulation.
- Input Phase Loss: Ripple indicates a missing input phase or blown fuse.
Fix: Inspect fuses and incoming power; we verify phase balance and replace protection if necessary.
- 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.
- Heatsink OverTemp: Heatsink temperature above limit (or very low).
Fix: Verify ambient, fan operation, and load; we replace fans and clean/recertify cooling path.
- Power Loss: DC bus <85% of nominal longer than [Power Loss Time].
Fix: Monitor AC for dips; we add ride-through measures as 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.
