1 kW HD servo motor for the SINAMICS S210 drive line
The Siemens 1FK2104-6AF10-1SA0 is a SIMOTICS S-1FK2 HD servo motor with 3.2 Nm static torque and 1 kW rated power at 3000 rpm when fed from a 380-480 V SINAMICS S210 drive, dropping to 0.5 kW at 1500 rpm on the 200-240 V input class — the same frame covers both voltage rails without a derate in the mechanical envelope. It is built for pairing with SINAMICS S210 in the 1FK2 servomotor family (Product Family 1FK2 servomotors for SINAMICS S210), which is the first thing to check when dropping it into a cabinet slot — a 1FK2 motor on anything other than the matching S210 drive loses the one-cable OCC interface.
Holding brake, encoder, shaft, plug
The motor ships with an integrated holding brake so the shaft locks when the drive is de-energised — vertical axes (lifters, Z-axis slides) keep position without a separate brake resistor or mechanical clamp. Feedback is an absolute encoder single-turn 22-bit (AS22DQC) on the rear of the motor, giving 4 million counts per turn for high-resolution positioning — the single-turn variant means the drive reads position on power-up without a homing run, but absolute multi-turn retention over a power-down is not on offer. The shaft is D19 x 40 mm with a feather key for positive torque transmission, the housing is IP64 (sealed against dust and splashing water — suitable for inside-cabinet and light washdown, not direct jet spray), and the connection side carries a rotatable M17 plug so the cable exit can be clocked to the cabinet layout without disassembling the motor.
Active production, made-to-order class
Lifecycle stage is recorded as current with product status Active — Siemens continues to manufacture the 1FK2 HD line and the 1FK2104-6AF10-1SA0 variant sits inside that active envelope. Product class is C: products manufactured / produced to order, which cannot be reused or re-utilized or be returned against credit — meaning the kit is built when the order is placed, not pulled from a finished-goods shelf, so the BOM line carries a non-standard return posture and the lead-time conversation starts at the RFQ. Compliance carries the standard Siemens substance-restriction posture: RoHS conformity since 01-07-06 and REACH Art. 33 duty-to-inform per the current candidate list (Reach Information provided on the product page), with no ECCN or AL control flags on export — ships under standard industrial-automation export rules.
Carton and kitting notes
Packaging dimensions are 452.00 x 250.00 x 267.00 mm for one piece — a single-motor carton is roughly half a metre on the long edge, so the receiving bench and the cabinet doorway both need to clear that footprint before the driver is called over. Quantity unit is 1 piece — the motor ships one per carton, so a multi-axis build orders N cartons and the kit list should treat each motor as its own line item with its own serial to keep the decl pack and the axis map aligned.
