What this motor delivers on the line
The Siemens 1FL2304-2AF01-0HB0 is a SIMOTICS S-1FL2 low-inertia servomotor in the 1FL2 family, sized for the SINAMICS S200 drive platform: 400 V 3AC supply, 0.4 kW rated power at a 3000 rpm nominal speed, with 1.45 Nm stall (M0) and 1.27 Nm rated (Mn). At 1.27 Nm rated against a 3000 rpm base, the motor is right-sized for small-format positioning axes — conveyor diverters, indexing tables, lightweight feeders, and packaging format changeovers — rather than high-inertia spindle duty.
Mechanical options and the panel-side interface
The build carries an AS17-bit absolute encoder, a plain shaft with tolerance N, no holding brake, and a shaft height of 45 mm — a 1FL2 low-profile frame that drops onto standard machine brackets without adapter plates. Connection is through an angular connector, which keeps the cable exit parallel to the motor body and is the practical choice where straight-on cable glands would interfere with adjacent axis hardware. Protection class is IP65 with oil seal, so the motor body resists coolant splash and cutting-oil mist around the shaft — fit for shop-floor cells where washdown is not required but gearbox oil migration is a real concern.
Drive pairing and commissioning envelope
The listed match is SINAMICS S200 — the 1FL2 family is qualified against this drive, and firmware auto-configuration expects this motor/encoder combination on first plug-in. Holding brake is omitted on this build (-0HB0 option code), so any axis that needs a fail-safe park position must be specified as a separate brake option or a downstream mechanical arrest.
Lifecycle, compliance, and ordering reality
Lifecycle stage is current and the brand position is active; RoHS compliance has been in force since 01-01-18, and REACH Art. 33 candidate-list obligations apply with the reach information document held on file. Product class C means the unit is produced to order and cannot be returned against credit — when the BOM line goes in, confirm quantity, encoder variant, and brake option up front, because a wrong-coded motor cannot be re-utilized. Group code R220 and product group X0DM identify the position in the Siemens catalog structure for internal ordering and warranty routing.
