Fagor 8025/ accuslide error 099, M-tables lost

Hi,

I have a '92 Hardinge/Accuslide retrofit with a Fagor 8025TG controller. When i got it the battery was dead and the parameters were lost. Between the manuals I got with the machine and research on the web I have reset all the parameters except for this one error.

Error 099 parity error Ms.
This indicates that the M tables are corrupted. When I go to the M-decoded function section, all I see are M?? listed. when I try to recall M03 for example, all I get is a checksum error.

I also get a checksum error when I view the leadscrew compensation parameters, although the parameters themselves look correct.

The manual says that error 099 will activate the internal emergency, meaning that the servos will not power up (like the E-stop has been pressed)

None of the manuals I have or anything I have found on the web tells me how to set the M functions when they screwed up like this. Does anyone know how to fix this?


Thanks
