Reading the order code suffix on -1LG0-Z-N05
The 1FK7034-5AK71-1LG0-Z-N05: The trailing -Z-N05 designation flags this build as a Z-variant with a customer-specific modification — a built-to-order configuration rolled up against the standard 1FK7 catalogue options. In practice that means the encoder type, holding brake option, shaft geometry, connector orientation, or a paint/sealing upgrade differs from the base catalogue entry, and the BOM line has to be matched exactly against the nameplate or the original Siemens configurator record before a reorder goes out. Sharing only the 1FK7034 frame digits is not enough; the -Z suffix is the deciding tag.
