Standstill torque M0=1.27 Nm defines the low-speed mechanical envelope: adequate for indexing tables and small-format converting axes where peak torque at start/stop matters more than continuous shaft power. Feedback is the AM22DQC absolute encoder — 22-bit single-turn plus 12-bit multi-turn — so position retention survives power-cycle loss without an external battery module, and the DRIVE-CLiQ M17 plug carries both encoder data and motor identification to the SINAMICS drive on a single cable. ## Mechanical fit and environmental envelope The housing carries IP65 protection, meaning the body resists dust ingress and low-pressure water jets — the motor can sit on a machine in a washdown-adjacent zone or in a dust-loaded cell, but not under direct high-pressure spray or full immersion. The shaft is cylindrical D19x40 mm, the standard 1FK2 frame for this kW class — a keyed or plain-bore coupling mates directly, and the 40 mm length gives enough bearing support for a pinion or small pulley stack. Power and signal both exit through M17 connectors, the same size on both sides — this keeps the cabinet-side cable gland and the feedback lead interchangeable across the 1FK2 low-inertia frame, which simplifies panel wiring spares. ## Compliance trail for incoming inspection ECCN license stamp or an ATR attachment — standard commercial invoicing is sufficient for most destinations, though end-use statements still apply for restricted end-users. Procurement classification lands at Group Code R220, Product Group 9021 — these are the line items the buyer's SAP or ERP system uses to bucket the motor against other Siemens drive components for tail-spend reporting. ## Lifecycle and BOM decision Product class is built-to-order with no return credit pathway, which is standard for a configured servo motor — the encoder, shaft, connector, and winding options are picked at order entry, so cancelling after cut-in means the unit is non-returnable. Packaging ships one piece per box at 452 x 250 x 267 mm, so a single spare fits a standard courier parcel and a multi-unit build needs a crate rather than individual cartons.","metaTitle":"Siemens 1FK2104-4AK01-0MB0 Servo Motor, 0.6 kW, 6000 rpm","metaDescription":"Siemens 1FK2104-4AK01-0MB0 SIMOTICS S-1FK2 HD servo motor, 0.6 kW at 6000 rpm, IP65, absolute encoder AM22DQC, DRIVE-CLiQ.
