The record on 1FK7042-2AC71-1RB0-Z shows eol_hot, which is the key read for any procurement decision. A line carrying a Siemens SIMOTION S120 or SINAMICS drive that was designed around a 1FK7 compact axis cannot drop a new replacement into the same shaft and encoder envelope without re-specifying — the motor selection, resolver/encoder feedback and shaft height all bind into the mechanical and electrical design below the motor. ## Sourcing posture for an eol_hot axis motor For an axis built around 1FK7042-2AC71-1RB0-Z, the practical question is whether spares are still quoted to order or only available through independent surplus.","metaTitle":"Siemens 1FK7042-2AC71-1RB0-Z Servo Motor, 1FK7 Compact","metaDescription":"Siemens 1FK7042-2AC71-1RB0-Z 1FK7 compact synchronous servo, listed as eol_hot.
