We had the batteries die on this machine and lost all parameters. We installed new batteries and got the machine running again after installing parameter backups that we had on file, it will home out perfect, we can run a program etc but it will not tool change on the turret. Looking at the ladder on the controller everything seems to be doing what it should up to the point of communicating with the pmc. In the ladder it calls for ucpc2 to unclamp turret but it is not being read it stops at this line and waits. Any ideas of what the issue could be? Thank you for any info you may have! Can attach pictures of the machine and I have a copy of the ladder if needed.
