Problem with Cintimatic Milacron 7VC-750

[kandrews]

Need help. Problem is on a Cintimatic Milacron 7VC-750, Acramatic 850 machine. Here is the problem:

When all of the axis are zero'd initially, the tool changer will operate correctly. If the table is moved again in any direction, the tool changer will not function and the machine will not function at all after that unless it is shut down and power re-applied. The Sector Master Module Error Code is A0. The cluster address is 04. I would certainly like some input on this and what area I should be looking in. Thanks
