Defining the unit
Siemens 1FK2104-5AF01-1SA0 is a SIMOTICS S-1FK2 HD servo motor from the 1FK2 servomotors for SINAMICS S210 product family, listed as current and shipped as a single piece. In a robot cell or indexing line, this motor is the torque-producing end of a SINAMICS S210 drive pairing via the OCC interface, so handshake latency between drive and motor feedback is closed at the converter bus rather than over a separate encoder cable run.
Duty points and where it lands on the nameplate
The nameplate carries two operating points: PN = 0.75 kW at nN = 3000 rpm on a 380-480 V supply, and PN = 0.375 kW at nN = 1500 rpm on a 200-240 V supply, with a stall torque M0 of 2.4 Nm — the 480 V point is the high-speed pick-and-place envelope, while the 240 V half-power point is the holding-torque regime on smaller cabinets. Because the same frame supports both ratings, wiring the motor into a 200-240 V drive derates continuous output to the half-kW figure without a thermal headroom penalty — the 2.4 Nm stall constant is the figure that closes the cycle budget for short accelerations.
Shaft, feedback, and the connector at the cabinet wall
Shaft is D19 x 40 mm with feather key; feedback is an absolute single-turn 22-bit encoder (AS22DQC); the power/feedback connector is an M17 plug, rotatable. The 22-bit single-turn resolution gives 1.048.576 counts per shaft revolution, which is what lets the cell close position loops without a homing routine at every restart. Degree of protection is IP65 — sealed against dust and low-pressure water jets, so it sits in factory-floor washdown-adjacent cells (food secondary packaging, beverage case-packing) but not in direct immersion or high-pressure cleaning zones where IP67 or higher is required.
Compliance and procurement fields
REACH Art. 33 information is supplied on request. Export Control Regulations list AL:N / ECCN:N_CNDU, which means no export licence is triggered for the destination classes under that regime. Group Code R220, Product Group 9021, Product class C — produced to order, not re-usable and not returnable for credit. Packaging is one piece per shipper with dimensions 452.00 x 250.00 x 267.00 mm. The made-to-order class is the line to flag internally: cancellations do not return stock to a saleable pool.
