Cause : Motor overload trip comes when the output current exceeds the motor full load current set in parameter. A motor overload occurs when a motor is subjected to excessive load or stress beyond its design capacity, leading to overheating and potential damage.

f007 fault in powerflex 40 drive indicates Motor overload trip.This means motor is under too much load and draws too much current.

Follow these steps to correct the fault:

1. Identify the Cause of Overload:

  • Excessive Motor Load:
    • Check for any mechanical issues like jams, binding components, or increased resistance in the load.
    • Ensure the motor is not undersized for the application.
  • Drive Parameter Misconfiguration:
    • Verify that the drive parameters, especially the motor current limit, are set correctly according to the motor's specifications.
  • Motor Issues:
    • Visually inspect the motor for signs of damage, overheating, or excessive wear.
    • If you suspect internal motor problems, consult a qualified electrician or motor specialist.
  • Line Voltage Fluctuations:
    • Monitor the AC line voltage feeding the drive using a voltmeter.
    • Ensure the voltage is within the specified range for the drive and motor.

2. Take Corrective Action:

  • Reduce Motor Load:
    • If possible, reduce the load on the motor to bring the current draw within acceptable limits.
  • Adjust Drive Parameters:
    • If the motor load cannot be reduced, you may need to increase the motor current limit parameter in the drive, but be cautious not to exceed the motor's rated current.
  • Replace Faulty Components:
    • If the motor or drive is damaged, it may need to be replaced.
