Servo Drive Fault Messages; Fault Messages Table; Chapter 10 Troubleshooting - Delta Electronics ASDA-B Series User Manual

If a fault is detected on the servo drive or motor, a corresponding alarm will be activated and the fault
message will be displayed on the LCD display of the digital keypad and the fault code will be shown on the
1-digit 7-segment LED display of the servo drive.
