Overheat in Motor

¿Qué significa 21 ?

This fault is triggered when an overheat input signal is detected on terminal X25, indicating that the motor has exceeded its safe operating temperature. This is typically activated by a thermal sensor integrated within the motor's windings or casing.

• Motor operating under excessive load, leading to overheating.
• Insufficient motor cooling due to fan malfunction, blocked ventilation, or high ambient temperature.
• Failure of the motor's internal thermal protection sensor or its connection to input X25.
• Incorrect parameter settings for motor current or acceleration/deceleration ramps, causing excessive heat generation.

1. 1

   Inspect the motor for signs of overheating, such as discoloration or unusual odors.

2. 2

   Verify the motor's cooling fan operation and ensure ventilation paths are clear.

3. 3

   Check the wiring and continuity of the motor's overheat sensor circuit connected to input X25.

4. 4

   Measure the motor's actual operating temperature to confirm if it genuinely overheats.

5. 5

   Review drive parameters related to motor current, acceleration, and load to ensure they are configured correctly for the application.
