    Default Puma 8S Y03 Amp Unequipped Spindle Stop Signal

    Just bought a 1997 Daewoo Puma 8S. Have run 2 jobs on it so far. Just booted it up Monday morning and have the error in the title. I've identified that the middle amp in the top of the cabinet is not lit up.

    This happened on Friday, and I turned the machine off, disconnected and reconnected all the DSUB cables going between amps. Turned the machine back on, and it started working and ran all day. Today, this is not working.

    I've ordered a couple replacement cables, but am concerned this is not the problem since I can't get it to work today. If it's an intermittent cable I'd think I'd be able to get it going. Am I barking up the wrong tree? What else can I check while I wait?

    The left AMP says "b" on the back while the right amp is flashing between "F1" and "E7". Can't find anything telling me what these mean.

    What is the serial number?

    What is the control model?

    What is the Amp Model or Part number?

    Crap!

    Everything I have to assist with servo drives is Fanuc oriented!

    I have not acquired information on the Mitsubishi drives.

    Sorry.

    I did get the machine running today, but no idea how. I just kept trying to turn it on occasionally. Once on, it runs great. I left it on tonight in hopes I don't have this problem tomorrow, but I don't want to leave it on 24/7.

    Anyone know if this sounds like how a bad spindle drive would behave?

    The amp that intermittently lights up is failing. You will need to replace it.

    That's what I was afraid of. Thank you for the confirmation.
