Cause: Encoder Thermal Sensor Error comes when the thermal sensor monitoring function has detected a thermal sensor error on the encoder module analog input due to "open circuit" or "short circuit".
"tECF" fault in Schneider ATV950 drive indicate " Encoder Thermal Sensor error". This means an issue with a specific temperature sensor (Th) within the encoder assembly. This sensor is crucial for monitoring the encoder's operating conditions and preventing damage due to overheating.
- Verify the sensor and its wiring.
- Ensure the temperature sensor is securely connected and there are no signs of damage to the wiring.
- Use a multimeter to check if the sensor is producing a voltage output within the expected range.
- Check the encoder's operating temperature to ensure it's within the specified limits.
