What this motor is and why it pairs with the S200
The Siemens 1FL2203-4AG01-1SC0 is a SIMOTICS S-1FL2 low-inertia servomotor from the 1FL2 family, designed to operate from the matching SINAMICS S200 drive — specifying the motor outside that drive family is the fastest way to lose comms or hit an encoder-version fault (cites:,). Mechanically it sits in the SH30 frame with a 200 V 3AC supply, 0.4 kW rated power, 1.27 Nm rated and standstill torque, 3000 rpm rated speed, a keyed shaft to tolerance N, no holding brake, and a hybrid cable exit connector — meaning the cable set and connector pinout are part of the motor, not separate order lines (cites:).
Reading the rating plate before you mount it
The 1.27 Nm continuous rating equals the standstill (M0) figure on this variant — so the motor can hold position at zero rpm at its continuous rating rather than only delivering transient torque from a stop (cites:). 3000 rpm rated speed on a 200 V 3AC bus is the operating point the SINAMICS S200 drive is sized for; exceeding it pushes the field-weakening region and the drive will derate or trip depending on the configured velocity limit (cites:). IP65 with oil seal is specified for the shaft end only — meaning the shaft sealing is wet/oily-splash suitable, but the cable entry and connector face still respect their own IP rating; a cordset that is not IP65 will back-convert the whole assembly at the wet end (cites:). The AS21bit absolute encoder in this build feeds position and commutation back to the SINAMICS S200 over the drive's serial interface, so the encoder version is fixed by the order-code suffix — swapping to a different 1FL2203 variant without updating the drive's encoder parameter block is a known commissioning trap (cites:).
Compliance paperwork to expect on the shipping carton
RoHS compliance has been in place for this part since 2018-01-01, so a buyer commissioning in the EU after that date should not need a separate substance-restriction waiver (cites:). Reach Information is supplied under Article 33 of REACH for any candidate-list substance present above the threshold — request the latest Reach Information sheet at quote time if a downstream EU manufacturer needs the declaration to close a BOM line (cites:). Product class C on this line means built to order with no reuse, re-utilisation, or credit return — spares planning should hold the BOM count, not assume stock returns for cancellations (cites:).
Procurement, lifecycle, and how to commit the line
Because the product class is C (made to order), the line is best handled as quoted-to-order against the BOM quantity rather than treated as a distribution-shelf SKU — pack quantity is 1 piece and outer-pack dimensions are 315 x 182 x 172 mm, which matters when staging spares in cabinets (cites:,). Group Code R220 / Product Group X0DJ are the ordering slots used on the Siemens commercial line; quoting against these codes keeps the BOM row audit-able when the purchasing system reconciles back to the factory order (cites:,).
