S300-SB Suffix

In 2011 we changed the S300 microprocessor to an upgraded version.  During this change there was an intermediary microprocessor used.

The generic S300 servo amplifier drive part number ended with an NA, like S30301-NA.  It had Hardware 3.01.

The intermediate S300 servo amplifiers's part numbers ended with SB, like S30301-NA-SB.

The new microprocessor started soon after, still in 2011 and we removed the -SB suffix, but the new Hardware was 4.0.

You may download parameters from HW 3.01 to HW4.0, but you cannot download parameters from HW4.0 to HW 3.01.
