What E05 means

Drive Overcurrent (Power Fault).

Shown as

  • IPM self-protection indicates major power fault

Likely causes, ranked

  1. Motor cables shortedlikely
  2. Motor winding shorted internallylikely
  3. Kinetix 6000 temperature too highlikely
  4. Operation above continuous power rating and/or environmental ratingslikely
  5. Kinetix 6000 short circuit, overcurrent or failed componentpossible

Quick checks

  • Verify continuity of motor power cable and connector

    Expected: Continuity good

  • Disconnect motor power cables and turn motor by hand

    Expected: Motor turns easily

  • Check for clogged vents or defective fan; ensure space around unit

    Expected: Cooling unrestricted

  • Verify ambient temperature is not too high

    Expected: Within rating

  • Remove all power and motor connections and check continuity from DC bus to U, V, W outputs

    Expected: No continuity

Fixes

Motor replacementlockout

  1. If motor is difficult to turn by hand, replace it

Operating limits

  1. Operate within continuous power rating
  2. Reduce acceleration rates

Drive shortlockout

  1. If continuity exists, check for wire fibers between terminals, or send drive in for repair
