The 1FK7044-4CF71-1CH0 is a Siemens 1FK7 high-dynamic synchronous servo motor from the SIMOTICS S family, the compact brushless line typically paired with SINAMICS S120 drive modules on packaging, converting, and tool-changing axes where short cycle times and high acceleration matter more than continuous stall torque.
For an EOL servo, expect lead time to be lot-dependent rather than a fixed factory schedule.
Not as a drop-in. The 1FK7044-4CF71-1CH0 and the 1FK7042-5AF71-1DB0 are different frame sizes within the 1FK7 family — the 1FK7042 lists 5.44 kg against the 1FK7044's 7.71 kg, and the winding, encoder, and braking options are order-code-specific, so shaft height, mounting, and the SINAMICS drive configuration would all need to be re-validated before any substitution could be approved.
