    fanuc OM-D power supply alarm at start up

    recently, when I power up my machine i got a lot of alarm, power supply alarm 01, spindle amplifier alarm 30 and alarm 414, 424, 434. but servo amplifier doesn't display any number. diagnostic prm 720 to 722 indicate an high current alarm(bit4 to 1). I clear and reload paramater and alarm goes away, until I power off/power on. I check back up battery voltage on Memory board, 4.72V, wich is fine. Why clear and reload parameter resolve the problem????

    The Power Supply "01" and Spindle "30" are both high voltage alarms. The 414/24/34 are high current alarms for servos, those are "effect alarms" They are just an effect of the real issue. The power coming into your power supply is high or not correct. Either that, or your Power Supply is damaged.

    Clear and reload solves the issue temporarily because you are setting the parameters to detect these issues.
