1 kW, 3.2 Nm continuous — sized for the SINAMICS S200 line
The 1FL2104-4BG11-1SC0 is a SIMOTICS S-1FL2 low-inertia servo from the 1FL2 family, built explicitly as the motor half of a SINAMICS S200 PN drive pairing — a 200 V 3AC supply rail, 1 kW rated power at a nominal 3000 rpm, with a continuous stall and rated torque of 3.2 Nm at the 40 mm shaft height. It carries an absolute 21-bit single-turn encoder on a hybrid connector and ships with a holding brake, so vertical-axis applications can hold position on power-off without an external brake resistor or mechanical latch. Lifecycle is active, so this is a current-production motor — not a stranded last-time-buy. Group Code R220 / Product Group X0DK place it in Siemens' standard ordering structure for indent and EDI lines.
What the ratings actually drive at commissioning
1 kW continuous at 3000 rpm nominal means the motor is sized for mid-range point-to-point motion — conveyor indexers, small packaging axes, tabletop gantry slides — not heavy machining spindles. The 3.2 Nm figure appears as both M0 (stall) and Mn (rated), so there is no torque foldback between standstill and running speed; the S200 can hold rated torque all the way down to low rpm without the current-boost headroom eating into thermal margin. IP65 with oil seal at the shaft exit means the motor body and shaft penetration tolerate light coolant splash and oil mist, but it is not IP67 or IP69K — high-pressure washdown or submerged duty needs a different housing rating. Holding brake is fitted from the factory, so the brake release and 24 V wiring land on the hybrid connector and tie directly into the SINAMICS S200's brake control, no separate brake rectifier. Tolerance N on the shaft keyway and a keyed shaft drive a press-fit coupling or pulley; if the downstream mechanics use a zero-backlash elastomer spider, the key seat is redundant but harmless. The 21-bit absolute encoder resolves position to roughly 0.0003° per count — enough for any S200 servo loop without an external measuring system.
Class C ordering terms and what they mean for stocking
Siemens lists this as Class C — manufactured to order, no return credit, no reuse. Practically, that means a cancellation or quantity reduction after the order is released typically cannot be restocked as a return; budget accordingly and order against firm BOM quantities, not optimistic forecasts. Packaging is 1 piece per shipper at 382 × 222 × 240 mm, single-unit logistics rather than multi-pack. RoHS compliance has been in force since 01-01-18 and REACH Art. 33 candidate-list information is available on request through the standard Reach Information channel — the motor carries no ECCN export restriction (AL:N / ECCN:N), so standard commercial export documentation applies rather than dual-use licensing. The S200 PN drive is sourced the same way, so a complete axis (drive + motor + hybrid cable) is one order line rather than three separate quotes.
