    HItachi Seiki HT20 yasnac lx3 control

    Any help would be greatly appreciated. Machine ran all last week perfectly. Turned it on this morning and got the following alarms
    391: Servo Pack Alarm (x)
    361: PG error (x)
    351: OL (x)
    310: Servo off

    I can't do anything. I turned axis by hand off switches. It turns out the operator may have shut the machine down on Friday during a homing cycle but not sure.

    If you can provide any advice, I would greatly appreciate it.

    Thanks in advance

    Hello,
    If it helps, I found that the power light on the servo pack is not lit. I don't know what would cause this.

    Thanks Again

    Steve, (if that is your name!)

    Those alarms are telling you the servo in question in of; could be powered but not in a ready state. What is the model of the servo. Does it have the DRO on it or just two lights (run & ready)

    Likely the turning off during a home cycle *shouldn't* be the cause; but stranger things have happened. Let me know that info and we will more forward

    John
