What the 1FK2204-5AK10-0SB0 brings to the SINAMICS cabinet
The Siemens 1FK2204-5AK10-0SB0 is a SIMOTICS S-1FK2 CT servo motor from the 1FK2 product family for SINAMICS S120 drives, with a static torque of M0 = 2.4 Nm and a rated power PN = 0.57 kW at nN = 6000 rpm on a 380-480 V bus (PN = 0.75 kW on a 200-240 V bus at nN = 3000 rpm), so the same winding covers both the high-speed 400 V class and the lower-voltage 230 V class without rewiring the panel. Built for the SINAMICS S120, it ships with an absolute encoder single-turn 22-bit (AS22DQC) and a DRIVE-CLiQ M17 plug plus a power connector size M17 — which means setpoint, commutation and diagnostics ride the same DRIVE-CLiQ cable the rest of the S120 line already speaks, keeping the cyclic telegram on the distributed-clock bus without a separate encoder cable to commission.
Holding brake, IP64 and 8 kHz current-loop tuning
The integrated holding brake lets the axis hold position with the drive powered down, which matters on vertical axes and on any load that must not sag when the controller faults or the line is de-energised. IP64 protection and a cylindrical shaft D19 × 40 mm suit typical cabinet-side and light-industrial mounting where the motor is not exposed to washdown; the 8 kHz / 62.5 µs current-loop rate pairs the motor to a fast SINAMICS S120 current controller for tight torque-loop response at the higher end of this 2.4 Nm frame.
Lifecycle, compliance and the BOM-line decision
Compliance paperwork on file covers the RoHS substance restrictions (since 01-07-06) and REACH Art. 33 candidate-list duty to inform, with no export-control flag under AL:N / ECCN:N_CNDU — the documentation set a panel builder needs for the EU market is already in scope. Availability and current pricing on this Siemens 1FK2 frame are confirmed at quote time against an RFQ; production per piece is built to order under Product class C (manufactured to order, non-returnable), which is standard for this motor frame.
Catalog fields the order desk uses
Group Code R220 and Product Group 9021 are the Siemens-internal classification carried on this order code, with a packaging quantity of 1 piece in a 452 × 250 × 267 mm shipper — the line item the procurement system keys on rather than the human-readable description.
