Reading the nameplate before you commit the BOM line
1FL2310-6AC01-1MB0 is a Siemens SIMOTICS S-1FL2 low-inertia servomotor from the family of 1FL2 servomotors for SINAMICS S200, supplied on a 400 V 3AC rail at a rated 7 kW with a base speed of 2000 rpm and a standstill torque of 35.2 Nm against a continuous rating of 33.4 Nm. The shaft-height-90 frame with key and AM21-bit absolute encoder on the angled connector targets the standard S200 single-cable drive commissioning profile, so the drive-controller pairing is defined by the family rather than a separate order code. The 400 V 3AC winding puts this motor squarely in the three-phase industrial envelope — not a 230 V single-phase drop-in — and the M0 35.2 Nm / Mn 33.4 Nm pair means the motor sits within roughly 5 % of its continuous rating from a standstill, which keeps the low-speed torque margin usable for indexing tables and short-stroke presses that hold position through the dwell.
Mechanical fit and what the IP65 oil seal changes
Shaft height 90 mm with a keyed shaft (tolerance N) drives the standard SH90 mounting footprint and the standard drive-end bearing stack used across the family; the angled connector AM21bit on the drive end leaves the cable exit lateral, which matters when the cabinet layout feeds the cable from the side rather than axially. The motor ships without a holding brake and carries IP65 protection with an oil seal at the shaft entry — the oil seal is the differentiator versus the IP65-only variant, because it lets the motor run near gearboxes or lubrication points without the gearbox mist migrating up the shaft into the encoder. For dry, clean cabinet environments the seal is overkill; for any line adjacent to a reducer or chain lubrication station it is the right call.
Drive pairing, control loop, and the encoder choice
The motor is specified as matched to the SINAMICS S200 drive family, so the encoder protocol, temperature sensor wiring, and power connector are designed to plug straight into the S200 module — no separate terminal module is required, which is what keeps the AM21bit angled connector on the order code rather than a third-party cable set. The 21-bit absolute encoder resolves about 2 arc-minutes per count, which is enough for most packaging-indexing and rotary-knife duty without a second external encoder on the load; if the application is a high-precision C-axis or a flying shear with tight registration, confirm whether the AM21 resolution is sufficient before freezing the order.
Lifecycle, compliance, and what 'made to order' means for spares
Product class on the order is C: products manufactured or produced to order, which cannot be reused or re-utilized or returned against credit. For the storeroom that means a unit pulled from the shelf for a wrong-spec replacement cannot be restocked; keep it on the shelf only when the application is committed and the mounting footprint, brake option, and encoder code are confirmed against the S200 project. Substance compliance is documented: RoHS conformity since 01-01-18 and REACH Article 33 disclosure on file per the current candidate list. Both are recorded in the manufacturer compliance pack, which is the documentation set most buyers ask for during an MRO audit of the drivetrain. Quoted to order against the project BOM — lead time and current pricing confirmed at RFQ. The 495 x 369 x 335 mm single-piece pack and one-piece quantity unit mean each unit ships in its own carton, which keeps the receiving dock plan simple but rules out splitting a master carton across multiple lines.
