On the panel or machine builder's side it slots into the standard Siemens servo cable and encoder ecosystem — the electrical fit is governed by the family, not this single dash code, so any cross-reference has to respect the resolver/encoder option and brake choice baked into the suffix. ## Where this motor sits in the lineup 1FK7 is the compact, high-dynamic family inside Siemens' synchronous servomotor range, and 1FK7040 specifically is the 63 mm shaft-height frame — sized for smaller axes (feed rollers, indexing tables, packaging heads, small-format converting) where 1FK7060 and 1FK7080 frames would over-spec the mounting.","metaTitle":"1FK7040-5AK71-1TB0 Siemens Servo Motor, 1.86 kg","metaDescription":"Siemens 1FK7040-5AK71-1TB0 1FK7 compact synchronous servo motor, listed weight 1.86 kg.
