What this Siemens order code actually is
The Siemens 1FL2105-2AF01-1MB0 is a SIMOTICS S-1FL2 low-inertia servomotor built to be driven by a SINAMICS S200 converter — the motor and drive are sold as a matched pair, and the suffix -1MB0 ties the motor to its S200 firmware variant. Supply is 400 V three-phase AC; the motor delivers 1.5 kW rated power with a stall torque of 5 Nm and a rated torque of 4.6 Nm at a rated speed of 3000 rpm — so the continuous working envelope is roughly 92% of stall torque at full speed, leaving little thermal headroom for sustained overloads above the rated point. It sits in a 52 mm shaft-height frame with a keyed shaft (tolerance N), no holding brake, an angular connector, and IP65 protection with an oil seal on the shaft pass-through — meaning the motor body and shaft entry are sealed against low-pressure water jets and oil mist typical of machine-tool and conveyor cells.
Encoder feedback and how it lands in the drive
Feedback is a 21-bit absolute encoder wired through an angular connector, which on the 1FL2/S200 pairing resolves to single-turn absolute position over the drive's internal comms — adequate for the cyclic point-to-point moves common in packaging and small-payload pick-and-place, where the cycle budget is tight and a homing return costs milliseconds every move. Because the encoder and motor are sold as a calibrated unit, substituting a third-party motor on the S200 drive is not a plug-in swap — the drive expects the motor's electronic nameplate data and encoder parameters on first commissioning.
Compliance documentation and order class
Siemens classifies the motor under group code R220 in product group X0DK, with compliance to RoHS substance restrictions confirmed since 01-01-18 and REACH Article 33 candidate-list information available on request. Export-control classification is AL:N / ECCN:N, so the part ships without a licence requirement under the standard dual-use lists — relevant for cross-border spares planning where paperwork holds up a line. The product class is C — manufactured or produced to order, which Siemens flags as non-returnable and non-reusable against credit; this matters for spares policy, because a cancelled BOM line cannot be walked back as a stock return.
