    96 Harrison Alpha 400 Spindle Fault detected!!!

    The machine runs great and will accept any program that I put in it. The problem is when I spin the chuck by hand to get to the chuck key I get a spindle fault detected code. I opened the back and it's
    flashing a 9 code. I've researched everything I could and can't figure out what I need to do next. I can shut the main power off and it will clear the code until the next time I have to turn the turn the chuck.

    Thanks for any help,

    Flashing 9 on spindle? What kind of spindle amplifier is it? (Alpha, Analog, Digital) Which FANUC control is on the machine?

    Hi Brent
    The Harrison is designed to detect and alarm if there is any movement of the chuck if in the chuck guard is in the down position
    Please make sure the chuck guard is up therefore and no alarms should happen
    I have assumed that this is what we would call a 400+ with only one keyboard if it isnt message me and I'll assist

    Thanks for the info on the chuck guard but everything seems to be working with that. I can have someone open and close the guard and watch the relays work.
    As far as which amplifier is on the machine not sure, I'm a newbie at most of this stuff.Attachment 360958Attachment 360956Attachment 360954

    According to our service manuals alarm 9
    Is the chuck guard switch and even though the switch is open it is not shutting power to the drive
    Change the switch and should be ok

    I took the chuck guard switch assembly apart and found the switch is fine. It was pressing in far enough to trigger the relays in the back but not
    enough to show the chuck guard open on the screen. I removed the cover and slotted the mounting holes so I could slide the switch closer to the
    cover guard. Where can I get one of those manuals?

    Thank you so much for your help.

    Hi!
    I have a similar problem. The spindle suddenly stops and I get a "Spindle Fault Detected" error but I get Alarm 2. Any idea what it means?
    Very grateful for any reply!
