Most Common Faults We Can Solve
These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.
- Output Phase Loss: Current lost in one/more output phases.
Fix: Check motor/drive wiring; we test phase continuity and repair output stage/wiring faults.
- Phase UV/VW/UW Short: Excessive current between output terminals.
Fix: Check for shorted motor/wiring; we repair/replace damaged output stage.
- 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.
- 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.
- 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.
- Motor Overload: Internal electronic overload trip.
Fix: Lower load below Motor FLA; we confirm FLA programming and motor sizing.
- Decel Inhibit: Bus regulation halts decel to limit DC bus.
Fix: Verify line & grounding, add DB resistor or lengthen decel; we configure/supply DB.
