I have a 1986 vintage Matsuura MC-500V2 mill with a Yasnac MX2 control. When I attempt to use work coordinate codes G54 through G59 I get an alarm code 020 which states,"unusable G code or G code not included in options programmed". Looking in the Yasnac operators manuel I see that G54 though G59 are listed as optional. So I'm assuming that there is nothing wrong with the control or the machine and that the original owner ordered it without work coordinates.
So the big question is, how do I turn this option on? I'm hoping it's only a matter of changing some parameters and not having to add or replace a board. Does anybody know? I've E-mailed the west coast Matsuura dealer for info but I fear any service they provide will be prohibitively expensive. I suppose I should also contact a Yasnac/Yasakawa service center. Can anybody suggest a good one?

Thanks
