Nikki Denso drive info needed

I need to replace an old Nikki Denso servo drive NPSA-GMDA-401Y2A2. I can't seem to find any info about the drive which makes it difficult to configure a replacement. It has about 48 dip switches and 4 rotary switches and I don't know what any of them do without a manual. Has anyone ever seen one of these before or have some documentation that you would like to share?
I need a miracle.

Have you tried the manufacturers website:

Look under the discontinued products.

Regards,

This particular model is not listed. They sent me two manuals with model numbers that have the same first two digits but they are not the same. I am thinking they are a special OEM item or something. It is on a Komori printing press.
