Most Common Faults We Can Solve
These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.
- 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.
- DB Resistance: Internal DB resistor ohms out of range.
Fix: Replace resistor; we supply/fit correct DB module and test.
- Decel Inhibit: Bus regulation halts decel to limit DC bus.
Fix: Verify line & grounding, add DB resistor or lengthen decel; we configure/supply DB.
- Phase UV/VW/UW Short: Excessive current between output terminals.
Fix: Check for shorted motor/wiring; we repair/replace damaged output stage.
- Cntl Bd Overtemp: Main Control Board over-temperature.
Fix: Check board fan and ambient; we replace fans and re-flow/replace the MCB if required.
- 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.
