Power On Self-Test： PWR Always On， RDY Blinking， LINK Always On， ERR Off.

V. Common Alarms

ALM30： Backplane Communication Failure → Check CN3 Cable， JCP10 Power Supply

ALM31： Encoder Abnormal → Wiring / Power Supply / Encoder Damage

ALM32： Bus Disconnected → Network Cable / Drive Power Off / Address Error

ALM33： Position Deviation → Mechanical Looseness / Parameters Incorrect
