06

Phase failure

SEW Eurodrive · [PDF] Operating Instructions

What does 06 mean?

The drive has detected a missing phase in the supply system leads. This fault is typically only detectable when the drive is operating under load, indicating an imbalance or complete loss of one or more input phases. Continued operation with a phase failure can lead to damage in both the motor and the inverter.

Common Causes

  • One or more phases are missing in the supply system lead.

Repair Steps & Checklist

Click steps to track your progress.

  1. 1

    Check the supply system lead for phase failure by measuring phase-to-phase voltages at the inverter input using a multimeter.

  2. 2

    Reset the fault by switching off the DC 24 V supply voltage to the inverter for at least 10 seconds.
