F7
Motor Overload
Allen-Bradley · PowerFlex 4 Adjustable Frequency
What does F7 mean?
This fault indicates an excessive motor load condition, where the motor's operating current has exceeded the thermal overload limit set by parameter P033 [Motor OLCurrent] for a sustained period. This protects the motor from overheating and damage.
Common Causes
- Motor is drawing excessive current, indicating overload.
- Motor torque exceeding its rated capacity.
- Mechanical binding or excessive friction in the driven system.
- Motor current limit reached (P1-50).
Repair Steps & Checklist
Click steps to track your progress.
- 1
Reduce the mechanical load on the motor to bring its operating current within safe limits.
- 2
Verify parameter P033 [Motor OLCurrent] is correctly set to the motor's nameplate full load amperage (FLA) or the maximum allowable motor current, not exceeding DriveRated Amps * 2.
