IP64 sealing on the housing means the body tolerates dust and splashed water but is not rated for washdown; the encoder and connector faces are the wet-side boundary, so the cordset glands carry the real sealing load once installed. ## Two voltage rails, one motor — what the rating actually means Siemens rates this frame at PN = 1 kW on a 380–480 V supply at nN = 3000 rpm, and PN = 0.5 kW on a 200–240 V supply at nN = 1500 rpm — the lower rail is the same physical motor running at half flux and half speed, not a derated variant, so a 230 V cabinet install is supported on the same order code without re-engineering the mechanical side. M0 = 3.2 Nm sets the stall torque the drive must command during acceleration peaks; the SINAMICS S120 controller should be configured against this figure rather than the continuous PN, because machine accel/decel cycles will pull closer to M0 than to rated load. ## Compliance, classification, and what 'made to order' means for the BOM The motor is listed under product class C — manufactured to order with no return-for-credit path — and ships as a single-piece unit in its own carton sized 452 x 250 x 267 mm, which is the planning reality for stocking: this is not a shelf item that goes into a generic inventory bin, it is a configured BOM line that ties to the SINAMICS S120 topology.","metaTitle":"Siemens 1FK2104-6AF00-1SB0 servo motor, 1 kW, IP64","metaDescription":"Siemens 1FK2104-6AF00-1SB0 SIMOTICS S-1FK2 HD servo, M0 3.2 Nm, 1 kW at 3000 rpm, IP64, DRIVE-CLiQ.
