Cincinnati t10 all axix moving when pressing the machine start button!!

hey guys, we have a Cincinnati t10 that seems to have some sort of ghost. When I turn the power on from the main the machine powers up just fine. When I press the machine start button the hydrolics kick on, but the axis start to move on their own slowly!!! As soon as I let off the machine start button the hydrolics kick off. Any ideas????
Thank you for your time!

That vintage machine will probably need more information to help you. What control and drives are on it?

What you described as the axes moving slowly is likely a balance issue so the axes are drifting while they are enabled. Since you seem to indicate all axes are doing this it would point to a common point that is shared by all axes and not something specific to each axis (however I have seen cases where a short in the machine wiring takes out all axis drives simultaneously).

Usually that problem is caused by the drive ready signal being stuck on. The software is waiting for a signal to come on that is already one.
What control? 900 for 950?
