Most Common Faults We Can Solve

These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.

  • Decel Inhibit: Bus regulation halts decel to limit DC bus.
    Fix: Verify line & grounding, add DB resistor or lengthen decel; we configure/supply DB.
  • 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.
  • 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.
  • 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.
  • Encoder Loss: One encoder channel missing (requires differential).
    Fix: Verify wiring, rotation, pulse rate; we replace encoder/cable and re-align.
  • Transistor OverTemp: Power devices exceeded safe temperature.
    Fix: Same as above—cooling & load audit; we replace failed fans/IGBTs and test.
