Drive Overload

What does F64 mean?

This fault indicates that the drive itself has experienced an overload condition, where its internal thermal model or output current has exceeded safe limits over a period of time. This protects the drive's power components from overheating.

• Drive's internal thermal monitoring detected excessive temperature.
• Motor current consistently high, causing drive heating.
• Insufficient cooling airflow to drive heatsink.
• Ambient temperature too high for drive operation.

Click steps to track your progress.

1. 1

   Reduce the mechanical load on the motor to decrease the current demand on the drive.

2. 2

   Increase parameter P039 [Accel Time1] or A067 [Accel Time2] to extend the acceleration time, reducing stress on the drive during startup.

3. 3

   Verify that the motor's actual running current under load does not consistently exceed the drive's rated output current.
