0.75 kW / 400 V 3AC servo in the SH40 frame
The Siemens 1FL2104-2BF01-0SC0 is a SIMOTICS S-1FL2 low-inertia servomotor built around a 40 mm shaft height, rated 0.75 kW (Pn) from a 400 V three-phase supply at a nominal speed of 3000 rpm, with both standstill torque and rated torque at 2.4 Nm. That torque-to-frame figure is the dimension the panel builder needs to confirm against the SINAMICS S200 it will drive — the motor and drive are sized as a pair, not separately.
Encoder, shaft, brake — what the order code locks in
The 1FL2104-2BF01-0SC0 ships without a holding brake and carries a plain shaft to tolerance N, so it relies on the downstream mechanics for any vertical-axis hold. Feedback is via a 21-bit absolute encoder wired through an AS-i hybrid connector, which keeps the cable between drive and motor to a single assembly rather than separate power and signal leads.
IP65 with oil seal — where it sits on the line
The motor carries IP65 protection with an oil seal at the shaft entry, so it tolerates the coolant mist and light splash around a small CNC tool changer, conveyor index station, or packaging indexing head — it is not rated for direct washdown. The hybrid AS-i connector entry is the wet-side interface; the sealing is at the connector, not the housing thread, so an unmated plug drops the enclosure class.
Configuration class and packaging
The listing falls under Product class C — built to order, non-returnable against credit — and ships as a single piece in a 315 x 182 x 172 mm package, which is the shape the receiving dock needs to plan for. Group Code R220 and Product Group X0DK are the internal Siemens taxonomy keys behind that ordering class.
