Sizing the drive against the nameplate
The Siemens 1FK2204-5AK00-2SA0 is a SIMOTICS S-1FK2 CT synchronous servo motor out of the 1FK2 family, the compact high-dynamics line designed to pair with the SINAMICS S210 drive platform — so before you commit a BOM slot, confirm the drive-side firmware profile and the OCC connector mapping on the S210 you have on the shelf. It is rated PN = 0.57 kW at nN = 6000 rpm on a 380-480 V bus, with a second operating point of PN = 0.75 kW at nN = 3000 rpm on a 200-240 V bus; the M0 = 2.4 Nm stall torque figure is the constant-torque ceiling that defines the lower-speed sizing band, not the rated point on the nameplate. The feedback is a 22-bit single-turn absolute encoder (AS22DQC) with the OCC interface — so when an apprentice asks why there is no battery box on the back, the answer is that single-turn absolute does not need one to retain position across power cycles, only multi-turn would.
Mounting, shaft and the cabinet layout
Shaft is a cylindrical D14 x 30 mm stub — no keyway on this variant — so coupling selection lands on a clamping or compression hub rather than a keyed coupling, and the integrator should budget for the larger bore when adapting to an existing gearbox input. Degree of protection is IP64, meaning the body is dust-tight and resists splashing water from any direction; it is not rated for washdown jets or submerged duty, so cabinet or shroud protection is required on a hygienic line. The power and feedback plug is M17, rotatable — the rotatable connector is the small kindness that lets the wireman orient the cable exit to the cable tray without twisting the leads inside the motor.
Compliance and what ships in the box
The motor has been compliant with the RoHS substance restrictions since 01-07-06, and REACH Art. 33 candidate-list duty-to-inform applies — the declaration pack on this listing carries both, which is what the doc-control check needs at goods-in. Product class is the Siemens 'C' class — built to order, non-returnable — so a panel builder who orders one extra as a spare is committing a non-refundable BOM line; confirm the build against the SINAMICS S210 drive configuration before the order is released.
