0.57 kW CT servo, sized for the SINAMICS S210 line
Siemens SIMOTICS S-1FK2 CT servo motor, order code 1FK2204-5AK01-0MA0, listed with M0=2.4 Nm stall torque and PN=0.57 kW at nN=6000 rpm on a 380-480 V bus, with a second rating of PN=0.75 kW at nN=3000 rpm on 200-240 V — the same frame, two operating points. It sits in the 1FK2 family for SINAMICS S210 drives, and the description names a cylindrical shaft D19x40mm, IP65 sealing, and a rotatable M17 plug for the power/OCC connector — the form-factor cues a panel-builder needs before measuring the cabinet footprint. Feedback is the AM22DQC absolute encoder, 22-bit single-turn plus 12-bit multi-turn, so position survives a power-cycle without a homing routine on restart — a real win on machines where the home flag is awkward to reach.
Why the dual voltage rating is the headline
Look at the two PN figures side by side: 0.57 kW at 6000 rpm on 380-480 V versus 0.75 kW at 3000 rpm on 200-240 V — same stator, two bus classes, so the integrator matches the drive's line voltage first and lets the constant-torque ceiling follow, not the other way around. IP65 with a D19x40mm shaft and a rotatable M17 plug means the motor is built for cabinet-edge or machine-mount duty where coolant mist and cutting fluid splash are normal — not for a washdown food-zone, not for outdoor exposure.
Packaging, codes, and what the order paperwork needs
Ships as a single piece in a 452.00 x 250.00 x 267.00 mm pack — keep the original carton on the receiving dock if the unit is going into bonded stock, because the Group Code R220 / Product Group 9021 markings drive the receiving inspection line. RoHS compliance since 01-07-06 and REACH Art. 33 disclosure obligations are noted; export control lists AL:N / ECCN:N_CNDU, so the shipping paperwork does not need an export licence for the usual destinations.
Class C build, active lifecycle, sourced per RFQ
Product class C — built to order, non-returnable, no restocking credit. That detail matters when you spec a spare: buy the second motor only when the line acceptance test is signed, not before.
