Cause : Incorrect temperature sensor setup comes when sensor type mismatch. The temperature sensor plays a crucial role in monitoring the drive's internal temperature. An incorrect setup can prevent the drive from accurately measuring the temperature, potentially leading to overheating and damage.

The A490 fault code in your ABB ACS560 drive indicates an incorrect temperature sensor setup. This means the drive is detecting an issue with how the temperature sensor is configured or connected.

• Check the settings of temperature source parameters 35.11 and 35.21 against 91.21 and 91.25.
