AL067 alarm in delta ASDA-A2 servo drive indicates Encoder temperature warning. This means encoder temperature exceeds the warning level. But it is still within the protective range.

1. Check the setting: Set the value of P0-02 to 120 to display the temperature.
2. Improve heat dissipation or reduce the loading of operation.
3. The temperature should be lower than 100°C (212°F).
