Pairing the SIMOTICS S-1FL2 to a SINAMICS S200
Siemens 1FL2310-2AC01-0SB0 is a SIMOTICS S-1FL2 servomotor out of the family built to feed a SINAMICS S200 drive — shaft height 90 mm, 400 V 3AC supply, paired through the motor-side power and feedback connector shown on the drive's S200 commissioning map. If a cabinet currently runs S200, this is the motor half of that motion axis; substituting a 1FL2 from a different series drops you back to the drive's compatibility matrix. The ratings that actually decide fit: Pn=3.5 kW, Nn=2000 rpm, M0=18.1 Nm stall, Mn=16.7 Nm rated — a roughly 8 % torque margin between rated and stall, which is what lets the axis take a brief overload pulse during accel without tripping the drive. Sizing logic on this family is rated-torque-first; the headline 3.5 kW number is the thermal continuous figure, not the peak.
Encoder, brake, and what that means on the floor
Feedback is a 21-bit absolute encoder delivered through the angular connector, so the drive knows absolute shaft position at power-up — no homing return on every restart, which on a packaging line is the difference between a five-second resume and a five-minute recovery. Single-cable hybrid connector: bring power and feedback down one cable run, not two, and check the drive-side mating connector against the S200 motor cable list before pulling wire. Configuration ships without a holding brake — Mn=16.7 Nm is the only thing arresting the load when the drive is disabled. For a vertical axis (lift, gravity-loaded slide), that means the drive's brake control loop or an external mechanical brake has to absorb the kinetic energy; on a horizontal conveyor or rotary table the lack of a brake is usually fine and saves the backlash.
IP65 with oil seal — where this motor physically belongs
IP65 rating holds with the factory oil seal fitted — a food-and-bev washdown zone, a lubricant-misted machine tool, or any outdoor skid with hose-down cleaning is in scope. Shaft height 90 mm is the SH-90 frame, so the mounting footprint matches the rest of the 1FL2 family at that height; a motor swap within SH-90 doesn't require a re-machined adapter plate.
Lifecycle, catalog codes, and what to expect at quote time
RoHS compliance has been on the record since 2018-01-01 and the REACH Art. 33 information duty is carried through the manufacturer's Reach Information page — standard for the 1FL2 family and what most EU and US plant intake teams expect to see. Group Code R220 / Product Group X0DM are the internal catalog keys used to route the RFQ to the right product family on the sourcing desk; they are not functional ratings. Packaging ships one motor per carton at roughly 495 x 369 x 335 mm — worth knowing for a receiving dock planning the unload path, since SH-90 servomotors are not light and a hand-off onto a high bay still wants a cart or hoist.
