I have a 1999 Mazak VTC 16B with the Fusion 640 control, turned the machine on this morning it went to its opening screen then this came up System Error Memory error detechted system halted. Machine has never had any issues.
Thank you for your help.
 
I had this same fault on a previous version of this control (M500). Here's a link to my story: http://www.practicalmachinist.com/vb/mazak/fjv-25-vertical-mill-parameters-q-249160/

Hope your parameters and any customizations are backed up. There is a procedure to clear, reload and reformat the memory after the problem has been addressed.

I know nothing about the 640 control but I would start by checking the backup battery voltage. You may end up replacing the NC board or at least the memory section of it. Mitsubishi Automation (MEAU) is helpful but they can only go so far as Mazak has personalized the control to match the machine.

Best o' luck,
