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.
- HW OverCurrent: Output current exceeded hardware limit.
Fix: Check programming & load; we review boost/DC brake settings and load profile.
- Input Phase Loss: Ripple indicates a missing input phase or blown fuse.
Fix: Inspect fuses and incoming power; we verify phase balance and replace protection if necessary.
- Encoder Loss: One encoder channel missing (requires differential).
Fix: Verify wiring, rotation, pulse rate; we replace encoder/cable and re-align.
- 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.
- 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.
- Heatsink OverTemp: Heatsink temperature above limit (or very low).
Fix: Verify ambient, fan operation, and load; we replace fans and clean/recertify cooling path.
