  Mrs. Susan BrownSep 3, 2025
  If your Delta Servo Drives are showing that the internal of the encoder is in error: * The internal of the encoder is in error. (The internal memory and the internal counter are in error): If issue persists, please send the drive back to the distributors or contact with Delta. * When power on, the motor operates because of mechanical inertia or other causes: When power on, please make sure the motor shaft stands still and will not operate.
