FF06 Motor overspeed fault in lenze i550 drive

Fault Code FF06 in a Lenze i550 drive indicates a motor overspeed fault . This means the motor connected to the drive is spinning at a speed that exceeds its rated maximum speed. Potential Causes Drive Configuration Issues: Incorrectly set maximum speed limit or frequency. Solution: Verify and adjust drive parameters to match the motor's specifications. Mechanical Problems: Jamming or Binding: Obstructions in the mechanical system can cause the motor to accelerate beyond its rated speed. Loose Coupling: A loose coupling between the motor and the driven load can lead to overspeed. Solution: Check for mechanical obstructions, ensure proper alignment, and tighten couplings as needed. Sensor Issues: A faulty speed sensor or incorrect sensor calibration can provide inaccurate speed readings, leading to overspeed. Solution: Verify the sensor's functionality, calibrate it if necessary, or replace it if faulty. Drive Internal Components: A fault within the drive's contr

7180 Motor overcurrent fault in lenze i550 drive

Fault Code 7180 in a Lenze i550 drive indicates a motor overcurrent fault . This means the motor connected to the drive is drawing more current than its rated capacity, which can lead to overheating and potential damage.
