Most Common Faults We Can Solve
These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.
- Ground Fault: >25% rating current to earth ground detected.
Fix: Meg-check motor and cable for ground; we isolate insulation faults and re-terminate.
- 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.
- 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.
- Phase UV/VW/UW Short: Excessive current between output terminals.
Fix: Check for shorted motor/wiring; we repair/replace damaged output stage.
- 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.
- 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.
- Encoder Quad Err: Both channels changed in one clock (noise or fault).
Fix: Reduce noise/replace encoder; we tidy shielding/grounds and retest.
