The 1FL2310-4AC01-1SB0 is a SIMOTICS S-1FL2 servomotor rated at 5 kW continuous power on 400 V three-phase supply, with a rated speed of 2000 rpm and a stall torque of 25.2 Nm (rated torque 23.9 Nm). That torque at zero speed means the motor holds position under load without needing a holding brake — this variant ships without one, so the axis relies on the drive's holding current or an external brake for vertical loads. The shaft height is 90 mm, which places it in the medium-frame range for this family. The AS21bit absolute encoder (22-bit single-turn, 12-bit multi-turn) gives the SINAMICS S200 drive full position feedback without a home cycle after power-up — useful for gantry or rotary axes where the machine must know its position immediately on restart.
IP65 with oil seal — washdown-ready integration
Protection class IP65 with an oil seal means the motor body and the shaft exit are sealed against dust ingress and low-pressure water jets. In a food, packaging, or machine-tool environment, this lets the motor mount directly in the washdown zone without a secondary cover — the oil seal also keeps cutting fluids out of the bearing cavity. The angular connector (AS21bit) exits at 90° to the motor axis, which keeps the cable profile low in tight cable-tray runs or when the motor is mounted close to the machine frame. The connector is keyed to the encoder type — an AS21bit absolute encoder, not incremental, so the mating cable must carry the SSI or BiSS protocol the S200 drive expects.
Active production, made to order — sourcing posture
RoHS compliance effective 01-Jan-2018 and REACH candidate-list disclosure are on file. No UL or CSA listing is stated in the record — confirm with the SINAMICS S200 drive system documentation if a UL-marked motor is required for the panel.
