Cause: Motor overtemperature comes when the motor temperature has exceeded the limit defined in the drive settings. If the motor has a built-in temperature sensor (e.g., PTC, KTY, thermistor) and this sensor is faulty or its connection to the drive is poor, it can send incorrect temperature readings.

f7011 fault in siemens drive indicate Motor overtemperature. This means the drive has detected that the motor's temperature has exceeded a predefined limit, and this is a critical issue that needs immediate attention to prevent permanent motor damage.

Troubleshooting Steps:

• Reduce the motor load.
• Check the ambient temperature and the motor ventilation.
• Check the wiring and the connection of the PTC or bimetallic NC contact.
• Inspect cooling – Is the motor fan running properly? Any blocked airflow?
