Siemens SIMOTICS S-1FL6 Servo Motor

Description

• 1FL6054​ → Frame size 60 mm (flange 60×60 mm), Rated torque 2.39 Nm (continuous), Rated speed 3000 rpm​ (some windings 2000 rpm — check suffix), Power ~ 0.75 kW.
  The -2AF21-​ segment indicates: 2 = shaft with key + seal, A = with holding brake?​ Actually in 1FL6 coding: position 6 of 20-char (the “2” after 1FL6054-) = brake flag: 2 = With brake (24V DC spring-applied), 1 = Without brake​ — so “-2AF21-” means WITH brake (2), Flange/Keyed shaft (F = keyed shaft), 21 = winding/signal variant.
• The last 4 digits (2AB1 / 2AG1 / 2AH1)​ mainly differentiate encoder type / connector orientation / option:
  • 2AB1​ → Typically Incremental encoder 20-bit + commutation info (TTL/HTL — for V90 system), Straight connector (or standard orientation), Single cable capable with V90 (via combined power+encoder cable).
  • 2AG1 / 2AH1​ → May indicate Absolute encoder (EnDat 2.1 single-turn or multi-turn — depends on region/version — some 1FL6 export versions have absolute encoder for S120 compatibility)​ or different connector orientation (right-angle vs straight) — always verify by full 20-character code or datasheet.In China/Asia domestic market 1FL6 usually ships with incremental 20-bit for V90 (2AB1); export/European versions may offer absolute (2AG1 = EnDat abs sometimes).
• Paired Drive: Recommended SINAMICS V90 (PN or analog version — e.g., 6SL3210-5FE10-8UF0 for 0.75kW/1.0kW V90 PN). Can also be used with SINAMICS S120 + CU310-2​ if encoder type matches (EnDat version required for S120 auto-ID — incremental version needs S120 with incremental eval + manual motor data entry).

Key Features

• Rated Torque (1FL6054): 2.39 Nm continuous @ 3000 rpm (peak ~ 7.17 Nm)
• Rated Power: ~ 0.75 kW
• Encoder: 20-bit incremental (for V90 — 2AB1) OR EnDat absolute (some -2AG1/-2AH1 export versions — confirm)
• Brake: Present on “-2A…-” (2 = with brake, 1 = without — check first digit after flange code)
• Ingress Protection: IP65 (with shaft seal), IP54 (motor body), IP67 optional on some
• Cooling: Natural convection (self-cooled)
• Country of Origin: China / Germany (Siemens DI LC)

Model & Variant Reference (1FL6054 Listed — Suffix = Encoder/Option)

⚠️ Critical Notes:

1. V90 System Prefers Incremental (2AB1): For hassle-free single-cable connection to SINAMICS V90, use the 20-bit incremental version (2AB1)​ — V90 auto-recognizes motor parameters from electronic plate (if V90 PN has “One Cable” capability — power+encoder in one hybrid cable 6FX500-___). The EnDat/abs version (-2AG1) is for S120 or V90 PN with absolute encoder option — more costly & needs correct drive FW.
2. Brake = “2” in 6th Char: 1FL6054-2AF21-… = WITH brake (24V DC spring-applied, released by energizing). If you need w/o brake look for “-1AF21-” (first digit=1 = no brake). Verify by full 20-char code!
3. Cables Sold Separately: For V90 + 2AB1 motor → order V90 hybrid cable (power+encoder in one): e.g., 6FX500-0MA06-0Bxx (length xx m — select by meter). For S120 + EnDat version → separate power (6FX2002-… M17/M23) + encoder (6FX2003-… EnDat M23 → SMC20/CU310-2).
4. Shaft & Key: “-F-” in code = keyed shaft with seal. Plain shaft (no key) is option “E” typically — check if your coupling requires keyway (most do).
5. Inertia Matching: 1FL6054 J_mot ≈ 0.00044 kg·m² — good for medium inertia loads. Check: T_motor ≥ (J_load/i² + J_mot) × α + Friction × r / η.

Technical Specifications (Representative — 1FL6054-2AF21-2AB1, 2.39 Nm, 3000 rpm, Incremental Encoder, w/ Brake)

Warranty & After-Sales

• Factory new units: 12 months warranty
• Refurbished units: 3-6 months warranty (spin test on V90 / S120 test rig — verify encoder count & brake release)
• Technical support for:
  • Drive pairing (SINAMICS V90 PN: 6SL3210-5FE10-8UF0 (0.75kW) or 6SL3210-5FE11-0UF0 (1.0kW) — size by motor current × safety factor; S120 + EnDat version if -2AG1)
  • Cable selection (V90: one-cable hybrid 6FX500-0MA06-0Bxx length; S120 EnDat: power 6FX2002-… M17 + encoder 6FX2003-… M23 → SMC20/CU310-2)
  • Brake wiring (24V DC release — V90 BRAKE terminal or external relay — ensure brake released BEFORE torque enable)
  • Encoder type confirmation (2AB1 = incremental for V90; 2AG1 = EnDat abs — for S120 or V90 PN abs option — verify before ordering!)
  • Inertia / torque check (T_motor ≥ T_load/gear + J_eq×α)
  • Cross-ref to 1FL6062 (next size up ~4.77 Nm) if undersized
• Optional: V90 drive, hybrid motor cable (6FX500-0MA06-0Bxx), brake release module, mating connector
