On a midnight startup where this motor is the suspect, the S120 drive fault LED plus the parameterised motor ID is what actually points at the swapped lead or the encoder fault — the diagnostics path is on the drive side, not the motor, which is why a replacement motor without a fresh declaration pack still leaves the commissioning engineer guessing.","metaTitle":"Siemens 1FK7040-5AK71-1KH5 Servo Motor, 4.08 kg, EOL","metaDescription":"Siemens 1FK7040-5AK71-1KH5 SINAMICS S120 servo motor, 4.08 kg, lifecycle EOL.
