What changes the value in this family

Option codes

Installed option codes. On configured units these are most of the value.

On the motor or drive nameplate, after the base part number.

Firmware revision

Firmware/FRN revision. Buyers match it to an existing project; a mismatch can make the unit useless to them.

On the label as "FRN" or "FW", and on the module's own display if it powers up.

Tested or untested

Tested / as-is / new-in-box. The single biggest multiplier on used price.

Not on the plate. It comes from whoever pulled the unit, and it moves the price more than anything printed.
