Most Common Faults We Can Solve
These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.
- 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.
- 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.
- DB Resistance: Internal DB resistor ohms out of range.
Fix: Replace resistor; we supply/fit correct DB module and test.
- Encoder Quad Err: Both channels changed in one clock (noise or fault).
Fix: Reduce noise/replace encoder; we tidy shielding/grounds and retest.
- HW OverCurrent: Output current exceeded hardware limit.
Fix: Check programming & load; we review boost/DC brake settings and load profile.
- Transistor OverTemp: Power devices exceeded safe temperature.
Fix: Same as above—cooling & load audit; we replace failed fans/IGBTs and test.
