Where this motor lands in a SINAMICS S120 cabinet
The Siemens 1FK2204-5AF10-2MB0 is a SIMOTICS S-1FK2 CT servo motor from the 1FK2 family built to pair with SINAMICS S120 drives, rated PN 0.75 kW at nN=3000 rpm on 380-480 V and PN 0.375 kW at nN=1500 rpm on 200-240 V — so the drive sizing has to respect the supply voltage tier, not just the kW figure. Stall torque is M0 = 2.4 Nm, giving the integrator a peak-torque headroom reference against the application's accelerating load; the motor carries an absolute encoder AM22DQC (22-bit single-turn + 12-bit multiturn) and a holding brake, which is the standard 1FK2 CT configuration for positioning axes where the load must hold still with the drive powered down.
Connectors, shaft, and the IP64 envelope
Connection to the S120 line-up is via DRIVE-CLiQ on an M17 plug, with a separate size M17 power connector for the motor cables — meaning a single hybrid cable carries feedback and power, the standard 1FK2 wiring pattern; the cylindrical shaft is D14 x 30 mm, so any coupling or pulley has to match that diameter and length. Degree of protection is IP64 — sealed against dust and splashing water, so the motor can sit on the machine frame near coolant splash and hose-down zones, but it is not rated for full immersion or high-pressure jet washdown; if the line includes a washdown station, an IP65 or higher 1FK2 variant should be selected instead.
Lifecycle, compliance, and order handling
Lifecycle is recorded as current and Active — production is open and the part is sourced as a made-to-order line: product class C, manufactured to order, non-returnable against credit, so any RFQ should carry the final voltage tier, shaft option, and connector choice before release.
Packaging and shelf footprint for MRO spares
Each unit ships in a 452 x 250 x 267 mm package — a compact servo carton that fits a standard MRO shelf bin; group code R220 and product group 9021 are the internal Siemens classification keys for the order entry, useful when matching against the procurement system.
