AL083 alarm in delta servo drive indicates Servo drive outputs excessive current. This means the output current from servo drive exceeds the setting level, AL083 will be triggered to protect IGBT. This could avoid IGBT to be burned out because of the excessive current.

1. Check the configuration of motor power cable and connector cable. See if the metal wire is exposed or AWG is worn and causes short circuit of UVW cable.
2. Check if there is any problem of lack phase when connecting UVW from servo to motor (unconnected or wrong connection).
