Most Common Faults We Can Solve
These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.
- 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.
- HW OverCurrent: Output current exceeded hardware limit.
Fix: Check programming & load; we review boost/DC brake settings and load profile.
- Heatsink OverTemp: Heatsink temperature above limit (or very low).
Fix: Verify ambient, fan operation, and load; we replace fans and clean/recertify cooling path.
- Load Loss: Torque current below [Load Loss Level] for set time.
Fix: Verify mechanical coupling; we check level/time and drive feedback.
- DB Resistance: Internal DB resistor ohms out of range.
Fix: Replace resistor; we supply/fit correct DB module and test.
- 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.
