On the 380-480 V drive bus it delivers PN=1.07 kW at nN=6000 rpm with a stall torque M0=2.4 Nm; on the 200-240 V bus it drops to PN=0.75 kW at nN=3000 rpm — the same frame, two voltage regions, one BOM line. The mechanical package is IP65 with a D19x40 mm shaft and feather key, fed through an M17 plug that is rotatable for cable routing in the cabinet. Position feedback is a 22-bit single-turn absolute encoder (AS22DQC) over the OCC interface — high-resolution commutation without battery backup or multi-turn gearing. ## Fit evidence against the BOM line The headline number is M0=2.4 Nm — that is the continuous stall torque the drive will regulate against at standstill, and it sets the ceiling for any short-term overload the application programmer will write into the S210 commissioning tool. Rated power is given conditionally: 1.07 kW on the 380-480 V supply at 6000 rpm, 0.75 kW on 200-240 V at 3000 rpm — the higher-voltage rating is the one the motor frame is mechanically sized for, the lower-voltage number is the same frame on a smaller drive. IP65 on the motor housing means it tolerates dust and low-pressure water jets — typical for cabinet-floor machine tools and packaging lines, not for direct washdown zones where IP67K would be the threshold. The 22-bit single-turn absolute encoder resolves 4,194,304 steps per shaft revolution — overkill for a simple positioning axis, expected where the SINAMICS S210 drives the motor into fine-interpolation contouring. ## Compliance, classification, and shipping Substance compliance: RoHS conformity since 01-07-06, REACH Art. 33 duty-to-inform applies with the candidate-list disclosure carried in the product record. Export classification is AL:N / ECCN:N_CNDU — no special export licence is triggered for typical industrial destinations, but cross-border shipments still require the standard commercial invoice trail. ## Sourcing posture for a configured S-1FK2 build Class C is a built-to-order configuration, not a stocked SKU — independent distribution sources it against an RFQ, with configuration integrity and traceability confirmed at quote time rather than off-the-shelf. Because the encoder variant, shaft, and plug are all part of the order code string, a like-for-like replacement must match the -1SA0 suffix rather than settling on a near-frame substitute — mismatched feedback or connector type shows up only at commissioning.","metaTitle":"Siemens 1FK2104-5AK01-1SA0 S-1FK2 servo, 2.4 Nm / 1.07 kW","metaDescription":"Siemens 1FK2104-5AK01-1SA0 SIMOTICS S-1FK2 HD servo for SINAMICS S210, M0=2.4 Nm, IP65, 22-bit single-turn encoder.
