What the 1FK2204-5AK11-1MB0 is built for
The 1FK2204-5AK11-1MB0 is a SINAMICS S120-matched servo motor in Siemens' compact SIMOTICS S-1FK2 CT line — 2.4 Nm holding torque with a spring-applied holding brake that holds the axis when the drive de-energises, which is the standard arrangement for any vertical load that must not drop on power loss. Rated 0.57 kW at 6000 rpm on 380-480 V three-phase and 0.75 kW at 3000 rpm on 200-240 V — the power figure changes with supply voltage because the motor is driven within the SINAMICS S120 inverter envelope, not direct-on-line. The AM22DQC absolute encoder delivers 22-bit single-turn resolution plus 12-bit multiturn, giving 4,096 revs of position memory before roll-over — enough for most rotary table and indexing axis applications without a homing cycle on every power-up. DRIVE-CLiQ is the digital serial bus that carries motor identity, encoder position, and temperature data back to the SINAMICS S120 control unit over a single M17 plug — the drive recognises the motor model and its parameters automatically on first boot, which eliminates one class of commissioning error on a machine retrofit. IP65 sealing means the motor body tolerates dusty and splash-prone environments — suitable for the outside-the-cabinet zone on a packaging line or a woodworking machine where coolant mist is present, provided the cable-entry side is properly sealed with a matching M17 cordset.
Made-to-order: what Class C means for your procurement
This order code carries Product Class C — manufactured to order, which means Siemens builds each unit against the purchase order and cannot reuse, re-utilise, or credit a returned unit. Export control classification is AL:N / ECCN:N_CNDU — no dual-use restriction applies, which simplifies procurement logistics for most industrial end-users.
Compliance and documentation
RoHS compliance is confirmed from 01-07-06, and REACH Article 33 duty-to-inform is flagged on the Siemens record — the full substance declaration is available through the Siemens Industry Online Support portal.
