F006

Motor Stalled

Allen-Bradley · PowerFlex 520-series Adjustable Frequency AC Drive

What does F006 mean?

The drive is unable to successfully accelerate or decelerate the motor to the commanded speed, indicating a motor stall condition. This typically happens when the mechanical load is too high, or acceleration/deceleration ramps are set too aggressively, causing the output current to exceed limits for an extended period. This risks motor and drive damage from overheating.

Additional Steps

Steps 1–2 are listed in Priority Fix.

  1. 3

    Inspect the motor and driven equipment for mechanical binding, bearing issues, or other failures preventing free rotation.

  2. 4

    Verify that the drive's current limits (A484, A485) are appropriately set for the motor and application.
