Drive Overload

Allen-Bradley · PowerFlex 4M Adjustable Frequency AC Drive

What does F64 mean?

The drive's internal overload protection has tripped, indicating that its output current has exceeded 150% of its rated capacity for 1 minute, or 200% for 3 seconds. This signifies that the drive is being asked to supply more power than it can safely deliver, risking damage to the drive's power components.

Additional Steps

  1. 3

    Verify the motor and drive ratings match the application requirements. If the drive is undersized for the load, it may need to be replaced with a higher-rated unit.
