Most Common Faults We Can Solve
These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.
- 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.
- Encoder Loss: One encoder channel missing (requires differential).
Fix: Verify wiring, rotation, pulse rate; we replace encoder/cable and re-align.
- Heatsink OverTemp: Heatsink temperature above limit (or very low).
Fix: Verify ambient, fan operation, and load; we replace fans and clean/recertify cooling path.
- HW OverCurrent: Output current exceeded hardware limit.
Fix: Check programming & load; we review boost/DC brake settings and load profile.
- I/O Comm Loss: I/O board lost comms with MCB.
Fix: Check connectors/noise; we replace I/O board or MCB if needed.
- 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.
- 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.
