AL074 alarm in delta ASDA-A2 servo drive indicates Absolute encoder single turn position error. This means absolute encoder single turn position error. 

  1. Check if the motor is well grounded.
  2. Check if the encoder cable is separated from the power supply or any high-current cable to avoid interference.
