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.
- 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.
- Encoder Quad Err: Both channels changed in one clock (noise or fault).
Fix: Reduce noise/replace encoder; we tidy shielding/grounds and retest.
- Ground Fault: >25% rating current to earth ground detected.
Fix: Meg-check motor and cable for ground; we isolate insulation faults and re-terminate.
- 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.
- 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.
