Where this motor sits in the cell
The 1FK70857AF711SG0 is a Siemens synchronous servo motor in the 1FK7 family, listed at 22 Nm continuous torque and 3000 rpm with resolver feedback and a plain shaft — a configuration that normally pairs with a SINAMICS S120 drive module over the DRIVE-CLiQ-style encoder chain on a high-dynamics axis. In a robotics cell, a 22 Nm / 3000 rpm motor of this class typically drives a wrist or auxiliary axis where cycle budget matters more than raw torque — the resolver feedback keeps the digital handshake tight to the controller, which is what closes the cycle budget on a palletizing or pick-and-place application.
Lifecycle read: eol_hot and what it changes
No official pin-compatible successor is listed for the 1FK70857AF711SG0 in this ledger, so a board-or-mechanical-swap to a newer 1FK7 variant or a current-generation equivalent is the integrator's call, not a guaranteed factory cross.
Spec fields on record
The description string on file — SVMTR 22NM 3000RPM ERN RES SHFT TOL — decodes to a 22 Nm, 3000 rpm motor with an ERN-series resolver and a tolerance-class plain shaft, which is the feedback and shaft combination a Siemens application note would flag as the standard for matched pairing with a SINAMICS S120 drive in a servo loop.
