Most Common Faults We Can Solve
These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.
- Encoder Quad Err: Both channels changed in one clock (noise or fault).
Fix: Reduce noise/replace encoder; we tidy shielding/grounds and retest.
- Load Loss: Torque current below [Load Loss Level] for set time.
Fix: Verify mechanical coupling; we check level/time and drive feedback.
- 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.
- 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.
