Drive Overload

Hva betyr F64 ?

This fault indicates that the drive itself is operating beyond its continuous current rating, typically due to an excessive motor load or an acceleration time that is too short.

• Prolonged operation of the motor at currents exceeding the drive's continuous current rating, leading to thermal overload.
• Insufficient acceleration time (e.g., P0-34 [Accel Time 1] or P0-35 [Accel Time 2]) for the connected load, causing sustained high current during startup.
• Mechanical issues in the driven system (e.g., worn gears, misaligned shafts, seized bearings) increasing the load on the motor.
• Drive cooling fan failure or obstructed heatsink fins, leading to inadequate heat dissipation from the drive's power components.
• Incorrect drive sizing for the application, where the drive's continuous current rating is lower than the actual motor load requirements.

1. 1

   Use a clamp-on ammeter to measure the motor current under load and compare it to the drive's rated continuous output current.

2. 2

   Increase the acceleration time parameter (e.g., P0-34 [Accel Time 1]) by 10-20% increments to reduce current peaks during startup.

3. 3

   Inspect the drive's cooling fan for proper operation and ensure that heatsink fins are free from dust and debris. Clean if necessary with compressed air.

4. 4

   Mechanically inspect the entire driven system for excessive friction, binding, or damage that increases the load on the motor and thus the drive.

5. 5

   Verify the drive is correctly sized for the motor and application; consider a larger drive if continuous current exceeds the drive's rating.
