What the 1FK2 CT motor delivers for a motion axis
The 1FK2204-6AF00-2SA0 is a Siemens SIMOTICS S-1FK2 CT servo motor — the compact, high-inertia variant in the 1FK2 family paired with the SINAMICS S210 drive line. Holding torque M0 is 3.2 Nm, and the motor delivers 1 kW mechanical output at rated speed 3000 rpm when driven from a 380-480 V supply. At half voltage (200-240 V) the same motor derates to 0.5 kW at 1500 rpm, which means the SINAMICS S210 supply voltage you spec into the axis sets the achievable power band — the 200-240 V slot is not a fallback, it is a deliberate lower-power operating point. The cylindrical shaft is D14 by 30 mm, which determines the coupling and encoder coupling dimensions on the load side. IP64 sealing on the motor body means dust-tight and protected against water spray from any direction — this is the ingress protection level for a motor that lives inside a machine envelope but sees coolant mist or washdown on the cabinet exterior, not a submerged or pressure-washed rating. For food-and-beverage or packaging lines where the motor sits behind a sealed door, IP64 is typically sufficient without the cost and size penalty of IP67.
Encoder resolution and OCC interface
The single-turn 22-bit absolute encoder (type AS22DQC) resolves 4,194,304 positions per revolution — fine enough that most indexing and positioning loops close entirely within the motor's own feedback without a separate linear scale. Because it is single-turn, absolute position is known within one revolution; for multi-turn travel the drive tracks revolutions internally after homing. The OCC (One Cable Connection) interface combines motor power and encoder feedback into a single rotatable M17 connector, which cuts the cable count at the motor face and simplifies routing in tight axis envelopes where every connector orientation matters.
Compliance and product-class realities
RoHS compliance is confirmed from 01-07-06, and REACH Article 33 duty-to-inform applies — the standard documentation package for a Siemens automation product entering EU supply chains. Export classification is AL:N / ECCN:N_CNDU, meaning no controlled-goods restrictions for most commercial distribution routes. The product class is flagged as C: manufactured to order, non-cancellable, non-returnable — this is a made-to-order line where the distributor commits the BOM quantity upfront and Siemens builds it to the order. Lead time and pricing are confirmed at RFQ, not from a live inventory figure.
