Servomotor definition for the 1FL2104-4AF01-0HC0
The Siemens 1FL2104-4AF01-0HC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 product family, sized to run on a SINAMICS S200 drive. Servomotors in this class deliver closed-loop torque and position control where a standard induction motor and VFD pair would stall on dynamic response — pick-and-place axes, feed drives on packaging lines, and short-cycle rotary tables are the typical fit.
Ratings that pin down the BOM slot
The motor is rated 1 kW continuous (Pn) at 3000 rpm (Nn), with stall and rated torque both listed at 3.2 Nm (M0 = Mn), supplied from a 3-phase 400 V AC bus. A matched M0/Mn figure tells the integrator the motor has no constant-power speed range collapse — peak torque equals rated torque, so any sizing pass that assumes a higher M0/Mn ratio overstates the axis capability. Mechanical interface is a 40 mm shaft height with a plain shaft (tolerance N), no holding brake, driven via a hybrid connector and equipped with an AS17-bit absolute encoder; the body carries IP65 with an oil seal, so the motor tolerates coolant splash and oil mist at the shaft exit but is not rated for submerged or high-pressure washdown duty. The motor is grouped under Group Code R220 and Product Group X0DK, sold in single-piece quantities with packaging dimensions of 382.00 mm × 222.00 mm × 240.00 mm, which matters when you floor-plan a receiving bench or stage replacements during a shutdown.
Commissioning pair-up with the SINAMICS S200
Because the motor is declared as a matched drive for the SINAMICS S200, the commissioning pass plugs straight into the drive's motor table — no encoder database import, no third-party ID lookup. The AS17-bit absolute encoder feedback means the drive resolves position on power-up without a homing sweep, which keeps the cold-start sequence on a packaging line under a second rather than several seconds of return-to-reference travel.
Compliance posture and material declarations
RoHS substance restrictions have applied since 01-01-18; the product also carries a REACH Article 33 duty-to-inform statement, and export classification is AL:N / ECCN:N. Product class C means each unit is built to order and cannot be returned against credit — spec the quantity into the BOM line, not against an inventory return window.
Lifecycle and what it means for the order
Production status is active (current), so this order code is on the Siemens build schedule rather than in a phase-out window. Because the product class is build-to-order with no return path, the practical move is to confirm quantity and lead time against your RFQ before locking the motor into a machine-build sequence — configurator output, line item count, and ship-from are all settled at quote time.
