Feedback is the AM22DQC absolute encoder at 22-bit single-turn plus 12-bit multiturn, brought back over a DRIVE-CLiQ plug M17, so the motor plugs straight into a SINAMICS S120 CU without an external SMC/SME module — the drive auto-identifies the encoder on first power-up. Mechanical side is a cylindrical shaft D14 x 30 mm with IP64 sealing, sized for typical high-dynamic packaging, indexing table and small-format converting machine duty where the 1FK2 HD torque class fits. ## Catalog trail and order handling Siemens files the code under Group Code R220 / Product Group 9021, and the order unit is one piece — Product class C, meaning the unit is produced to order and cannot be reused or returned against credit, so the BOM line should be frozen before the RFQ goes out rather than treated as cancellable stock. Export Control marks AL:N / ECCN:N_CNDU, which means the part ships without a dual-use export licence gate for most destinations; still flag the destination country before the RFQ if the build is non-domestic. The motor ships in a 452.00 x 250.00 x 267.00 mm pack at one piece per carton — give the receiving bench that footprint and keep the original Siemens inner foam set until commissioning, because the AM22DQC encoder zero is preserved across transit and gets re-referenced by the drive on first commissioning. ## Lifecycle posture and compliance trail RoHS compliance has been on file since 01-07-06 and REACH Art. 33 duty-to-inform is carried via the standard Siemens Reach Information page, which is what the buyer-side compliance reviewer will look for on the declaration pack rather than a per-shipment certificate. ## What the buyer actually came to find out The headline sizing decision is the 0.6 kW at 6000 rpm rating paired with the 1.27 Nm standstill torque — that combination defines the mechanical load envelope for the axis and is the number to match against the SINAMICS S120 line module sizing, not just the nameplate kW. The DRIVE-CLiQ M17 interface is the integration hinge: the matching power connector is the M17 size on the motor pigtail, so the cabinet-side cable set has to be ordered against the same M17 power + DRIVE-CLiQ M17 feedback pairing — mixing M23 power with the M17 feedback half is the common panel-build miss on first installs. Because Product class is C (made to order, no return credit), a sourcing RFQ should carry the exact M0 / PN / nN values, the encoder variant AM22DQC, and the shaft code D14 x 30 mm so the order cannot drift to a near-sibling within the 1FK2 family.","metaTitle":"Siemens 1FK2104-4AK00-2MB0 Servo Motor, 0.6 kW, IP64","metaDescription":"Siemens 1FK2104-4AK00-2MB0 SIMOTICS S-1FK2 HD servo motor, 0.6 kW at 6000 rpm (380-480 V), IP64, DRIVE-CLiQ M17.
