Define the motor before you size the drive
The 1FL2205-2AF01-1MB0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 family, wound for a 400 V 3AC supply, rated 1 kW continuous at a nominal speed of 3000 rpm with a stall torque M0 of 3.6 Nm and a rated torque Mn of 3 Nm, and it pairs specifically with the SINAMICS S200 drive line.
Reading the ratings against the S200 channel
On a 400 V 3AC bus the motor delivers its 1 kW at 3000 rpm; the 3.6 Nm stall against a 3 Nm rated figure means roughly a 20 % torque reserve at zero speed, which is the working headroom the SINAMICS S200 uses for acceleration and load transients without tripping on overcurrent. The encoder side is the AM21bit absolute multi-turn unit, fed to the S200 over the matching drive-side cable — for commissioning the encoder resolution is what sets the achievable positioning accuracy, not the motor itself, so the S200 firmware must be loaded with the AM21 profile before the first reference run.
Mechanical fit on the machine side
Shaft height 48 mm with a keyed shaft (tolerance N) and no holding brake — meaning any safety-rated stop on this axis is the drive's job through the S200's STO/SS1 functions, not a mechanical failsafe at the motor. The IP65 rating with oil seal applies to the body and the shaft entry when the power and feedback connectors are mated; the angular connector orientation on this variant (-1MB0) is fixed at build, so the cable bend radius and the cabinet entry need to be checked against the connector exit direction before the motor is bolted down.
Ordering codes and compliance envelope
Substance compliance since 01-01-18 per RoHS, with REACH Art. 33 disclosure supplied with the shipment; export classification is AL:N / ECCN:N, so no dual-use export licence applies for cross-border shipment.
Sourcing posture for the BOM line
Because the product class is build-to-order, planning a spare for a line-down event means quoting the lead time up front — quote time and current pricing are confirmed against the RFQ; no stock-holding or same-day-ship claim attaches to this code. Shipping carton is 382 x 222 x 240 mm for a single-piece pack — relevant when specifying the receiving bay footprint for an incoming inspection cell.
