For an integrator with a SINUMERIK or SIMOTION line that was originally built around this motor, that means a last-time-buy window is closed and the BOM line has to flip to a sourced-from-stock posture: lead time and current pricing are quoted only at the time of order, and date-code traceability follows whatever the broker channel can document. ## Mechanical envelope and handling On a panel retrofit, the resolver or absolute encoder feedback cable and the power conductors terminate at the same Siemens-standard connector family used on other 1FK7 motors, so the panel-side gland plate cutout stays valid as long as the drive-side SINAMICS parameter set matches the motor's rated torque/inertia profile.","metaTitle":"Siemens 1FK7044-4CH71-1RG1 Servo Motor, 7.26 kg","metaDescription":"1FK7044-4CH71-1RG1 Siemens 1FK7 high-dynamic synchronous servo motor, 7.26 kg.
