Cause : HW OverCurrent comes when the drive output current has exceeded the hardware current limit. The drive detected an extremely high current spike that bypassed software control, the hardware protection circuit inside the drive itself triggered.

f012 powerflex indicate "HW OverCurrent" or "Hardware Overcurrent" fault. This means the drive's output current has exceeded its internal hardware limits.

Troubleshooting Steps:

Follow these steps to correct f012 powerflex:

• Check motor and motor cable.
• Check the wiring at the drive's output terminals for any loose connections or accidental shorts.
• Make sure motor nameplate info matches drive programming (Motor voltage, rated amps, frequency, etc.).
• Try increasing the acceleration and deceleration times to reduce the rate of current change.
