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.
- Encoder Quad Err: Both channels changed in one clock (noise or fault).
Fix: Reduce noise/replace encoder; we tidy shielding/grounds and retest.
- 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.
- OverSpeed Limit: Speed correction exceeded [Overspeed Limit].
Fix: Remove overhauling load or raise limit; we re-tune slip/bus regulation.
- Ground Fault: >25% rating current to earth ground detected.
Fix: Meg-check motor and cable for ground; we isolate insulation faults and re-terminate.
- I/O Comm Loss: I/O board lost comms with MCB.
Fix: Check connectors/noise; we replace I/O board or MCB if needed.
- 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.
