Hi,
I have several bad MR-J2S-B servo amplifers and I do not really want to give up them. I judge the trouble reason is that the firmware of main controller---SH7065 had been lost. Fortunately, I have some good amplifers in hand with the same model. Can I get the firmware from a good one and re-programme those bad? or where can I downlaod the firmware I need?
Please help!

Thanks and Regards,
