Cause: Motor blocked comes when the motor is unable to rotate freely, preventing the drive from achieving the desired speed. The motor is drawing more current than its rated value for an extended period.

f015 siemens fault indicates an motor blocked condition. This means the thermal model within the drive has calculated that the motor has been subjected to an excessive current over time, leading to potential overheating.

Troubleshooting Steps:

Follow these steps to correct the f015 siemens fault:

• Measure Motor Current: Use a clamp meter to measure the actual current drawn by the motor during operation.
• Compare Nameplate Data: Carefully check the motor's nameplate for its rated voltage, current, frequency, and other relevant data.
• Check for Overheating: Feel the motor casing for excessive heat.
• Check Drive Parameters: Ensure that the motor parameters programmed into the drive exactly match the motor's nameplate.
