Most Common Faults We Can Solve
These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.
- Drive OverLoad: 110% for 1 min or 150% for 3 s exceeded.
Fix: Reduce load or increase accel time; we profile current vs. cycle and tune ramps.
- Load Loss: Torque current below [Load Loss Level] for set time.
Fix: Verify mechanical coupling; we check level/time and drive feedback.
- 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.
- 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.
- Pulse In Loss: Z-channel selected but no pulses present.
Fix: Check wiring and pulse generator; we replace failed pickup.
- Decel Inhibit: Bus regulation halts decel to limit DC bus.
Fix: Verify line & grounding, add DB resistor or lengthen decel; we configure/supply DB.
- 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.
