Sizing the drive match for SINAMICS S200
The 1FL2104-4BF01-1SC0 is a SIMOTICS S-1FL2 low-inertia servo in the 1FL2 family, intended as the matched motor half of a SINAMICS S200 drive package. The 400 V 3AC supply rail, Pn of 1 kW, Nn of 3000 rpm, and M0 of 3.2 Nm (equal to the rated Mn) confirm a constant-torque profile across the working speed range — the drive sizing calculation does not need a separate field-weakening allowance. For audit purposes the shaft height is 40 mm, the encoder is the 21-bit absolute single-turn type on a hybrid connector designated AS, and the shaft carries a half-key with N tolerance. There is no holding brake — if the application requires a safe-stop-held axis, a brake-equipped variant in the same family must be specified instead.
Sealing, oil resistance, and cabinet-side integration
Protection class is IP65 with oil resistance, per the description block; the motor body and shaft seal are rated for the coolant and lubricant mist found around a typical cutting or transfer machine, not for direct jet washdown. Mounting is flange-style on the 40 mm shaft-height footprint, and the hybrid connector exits on the same face so the cabinet gland layout can be planned against the 315.00 x 182.00 x 172.00 mm shipping envelope noted in the packaging data.
Order unit, lifecycle, and how to source
Lifecycle stage is recorded as current, and the quantity unit is 1 Piece with packaging quantity 1. Product class C applies — manufactured to order, not returnable against credit — so the order must be sized to the actual axis count rather than over-spec'd on the assumption of returnable shelf stock.
