Most Common Faults We Can Solve
These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.
- 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.
- 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.
- DB Resistance: Internal DB resistor ohms out of range.
Fix: Replace resistor; we supply/fit correct DB module and test.
- Heatsink OverTemp: Heatsink temperature above limit (or very low).
Fix: Verify ambient, fan operation, and load; we replace fans and clean/recertify cooling path.
- 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.
- Motor Overload: Internal electronic overload trip.
Fix: Lower load below Motor FLA; we confirm FLA programming and motor sizing.
- 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.
