Where this 1FK2 HD fits on a packaging or assembly line
The Siemens 1FK2104-4AK11-1SB0 is a SIMOTICS S-1FK2 HD servomotor designed to sit on a SINAMICS S120 drive line, pairing with the controller over a DRIVE-CLiQ M17 feedback plug and a size M17 power connector. The holding brake and IP65 rating on the body mean the motor is sized for machines where the shaft has to hold position when the drive is de-energised and where the cabinet-side environment sees washdown or airborne oil. Two operating points are published on the rating plate: 0.6 kW at nN=6000 rpm on a 380-480 V supply, and 0.4 kW at nN=3000 rpm on a 200-240 V supply, with M0=1.27 Nm static torque. The 200-240 V point covers North American single-phase-fed drive cabinets, while the 380-480 V point is the European/Asian three-phase default.
Mechanical and feedback package
The shaft is D19x40 mm with a feather key, the encoder is an AS22DQC single-turn 22-bit absolute encoder, and the housing is sealed to IP65. For a packaging-machinery builder that means the feedback resolution is sufficient for index-and-orient stop routines without needing a battery-backed multi-turn module, and the brake release is wired through the same M17 power plug that carries the motor phases. This variant carries a holding brake as standard — the -1SB0 suffix is the brake option in the 1FK2 order-code structure — and is ordered in single-piece quantity per the Product Group 9021 / Group Code R220 cataloguing. Export classification is AL:N / ECCN:N_CNDU, which simplifies cross-border shipments.
Lifecycle, ordering terms, and compliance
For the documentation pack a procurement audit will ask for, the RoHS date and the REACH statement are the entries that travel with the shipment. The motor ships in single-piece pack at 452.00 x 250.00 x 267.00 mm — useful for crate planning on a panel-builder receiving dock.
