64

Drive Overload

Allen-Bradley · PowerFlex 700

What does 64 mean?

The drive's output current rating of 110% for 1 minute or 150% for 3 seconds has been exceeded. This indicates the drive is being asked to supply more current than its continuous or short-term rating, risking thermal damage to the drive's power section.

Common Causes

  • Motor current exceeding rated capacity for an extended period.
  • Overload protection threshold (e.g., P1-03) set too low.
  • Excessive torque demand for the motor size.
  • High ambient temperature affecting heatsink performance.
