Most Common Faults We Can Solve
These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.
- Motor Overload: Internal electronic overload trip.
Fix: Lower load below Motor FLA; we confirm FLA programming and motor sizing.
- Ground Fault: >25% rating current to earth ground detected.
Fix: Meg-check motor and cable for ground; we isolate insulation faults and re-terminate.
- Encoder Loss: One encoder channel missing (requires differential).
Fix: Verify wiring, rotation, pulse rate; we replace encoder/cable and re-align.
- 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.
- 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.
- Phase U/V/W to Ground: Phase-to-ground fault detected on the output.
Fix: Check motor cable/motor for grounds; replace drive if damage found.
