3.2 Nm, 1 kW at 3000 rpm — what the motor actually delivers
The Siemens 1FK2204-6AF11-0SB0 is a SIMOTICS S-1FK2 CT servo motor from the 1FK2 family built to plug into SINAMICS S120 drives, with a standstill torque of 3.2 Nm and a rated output of 1 kW at a nominal 3000 rpm on a 380-480 V supply, dropping to 0.5 kW at 1500 rpm on 200-240 V for panels fed off a lower mains tap. The DRIVE-CLiQ M17 plug handles the encoder and electronic nameplate link to the drive, so commissioning pulls the motor data straight from the motor without a manual parameter entry. It ships with a holding brake for vertical-axis or gravity-loaded applications, an IP65 housing that shrugs off coolant splash and cutting mist around the machine, and an absolute encoder single-turn 22-bit (AS22DQC) that gives the drive position feedback without a homing run on power-up. The power connector is the same M17 size as the DRIVE-CLiQ plug, which means the cable gland layout on the machine side needs to clear both connectors side-by-side — confirm the bend radius on the drag-chain routing before locking the motor mounting.
Built to the SINAMICS S120 drive line — pairing notes
As an S-1FK2 CT motor with DRIVE-CLiQ, the 1FK2204-6AF11-0SB0 is wired into a SINAMICS S120 line via the drive's motor module — the electronic nameplate travels over DRIVE-CLiQ on first connection, so the drive auto-configures the motor parameters and current limits. The cylindrical shaft D19x40 mm and the brake interface follow the standard 1FK2 frame, so existing shaft couplings and brake cables in the same frame family are reusable when swapping in this variant on an existing axis.
Compliance, group code, and order class
Siemens classifies this motor as Group Code R220 / Product Group 9021, packaged one per box with outer dimensions 452 x 250 x 267 mm, and lists it as Product class C — built to order, not returnable for credit.
Lifecycle read — active and built to order
Lifecycle is recorded as active, which on a Product class C line means each unit is configured and produced against the order — there is no shelf stock at the factory level.
