PowerFlex 700 20BD096F3ANNACC1 | Repair or Stock Options

Most Common Faults We Can Solve

These are frequent PowerFlex 700 issues. We diagnose quickly and repair at the component level.

• Load Loss: Torque current below [Load Loss Level] for set time.
  Fix: Verify mechanical coupling; we check level/time and drive feedback.
• Phase U/V/W to Ground: Phase-to-ground fault detected on the output.
  Fix: Check motor cable/motor for grounds; replace drive if damage found.
• HW OverCurrent: Output current exceeded hardware limit.
  Fix: Check programming & load; we review boost/DC brake settings and load profile.
• 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.
• 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.
• 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.
• Encoder Quad Err: Both channels changed in one clock (noise or fault).
  Fix: Reduce noise/replace encoder; we tidy shielding/grounds and retest.
