Where this motor sits on the S210 drive line
The Siemens 1FK2104-4AK00-2MA0 is a SIMOTICS S-1FK2 HD servo motor built for the SINAMICS S210 drive platform, with a stall torque M0 of 1.27 Nm and a rated power of 0.6 kW at 6000 rpm on a 380-480 V bus, or 0.4 kW at 3000 rpm on a 200-240 V bus — meaning a single motor SKU spans both the European 400 V class and the North American 230 V class without re-specifying the part number. Siemens lists the product family positioning plainly: 1FK2 servomotors for SINAMICS S210, so the encoder protocol, holding-brake option, and connector geometry are matched to that drive at the firmware level rather than adapted later.
Encoder, shaft, and connector fit
Feedback is the AM22DQC absolute encoder at 22-bit single-turn plus 12-bit multi-turn resolution, which lands absolute position on the drive at power-up without a homing move — useful for machine builders who need the axis referenced before the first motion command. The shaft is a cylindrical D14 x 30 mm stub without a keyway, paired with the OCC (One Cable Connection) interface through an M17 rotatable plug, so the power and feedback conductors share a single cable run back to the SINAMICS S210 — fewer drops in the cable carrier and one connector to land at the drive. Degree of protection is IP64 on the motor housing, which is the standard for cabinet-internal or light-dust industrial duty; the motor is not specified for washdown or outdoor mounting as supplied.
Lifecycle status and what the order code carries
Lifecycle stage is recorded as current and the product status is Active, so the part remains in normal production under Siemens' standard configurator and is specifiable into new BOM lines without a last-time-buy gate. The order code carries Group Code R220 and Product Group 9021, which is how Siemens' own ordering system keys the SKU for pricing and lead-time confirmation — the same identifier the buyer will see on the order acknowledgment.
Compliance and paperwork that travel with the motor
Export control classifications show AL:N and ECCN:N_CNDU, which means no specific export license is triggered for this SKU under the stated categories, simplifying shipment to most industrial destinations. Product class is recorded as C: products manufactured or produced to order, which cannot be reused or re-utilized or be returned against credit — meaning this is a build-to-order configurator SKU and standard 30-day return windows do not apply once the unit ships. Packaging is one piece per shipper at 452.00 x 250.00 x 267.00 mm, the standard single-motor Siemens pack size for the 1FK2 frame.
