Hi guys.
I'm running a SCM router with xilog plus and have hit an "inverter frequency error" message, it is to do with the tool selections restarting on me and the SCM guys told me I needed to manually drop the tool and put it back on the external rack, however I am unable to use the head release function. I press the button correctly and activate "cycle start" although nothing happens.
Any advice is welcome at this point.

Cheers guys
