Most Common Faults We Can Solve
These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.
- 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.
- 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.
- 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.
- Cntl Bd Overtemp: Main Control Board over-temperature.
Fix: Check board fan and ambient; we replace fans and re-flow/replace the MCB if required.
- Load Loss: Torque current below [Load Loss Level] for set time.
Fix: Verify mechanical coupling; we check level/time and drive feedback.
- Ground Fault: >25% rating current to earth ground detected.
Fix: Meg-check motor and cable for ground; we isolate insulation faults and re-terminate.
