Servo motor built around the SINAMICS S120 drive line
The Siemens 1FK2204-5AK11-0MB0 is a SIMOTICS S-1FK2 CT servo motor from the 1FK2 servomotor family, sized for direct connection to a SINAMICS S120 drive via the DRIVE-CLiQ plug M17 with a matching power connector size M17 on the motor side. The shaft end is a cylindrical D19x40 mm stub with an integrated holding brake, and the absolute encoder AM22DQC delivers 22-bit single-turn plus 12-bit multiturn resolution — enough for positioning axes that need to retain absolute position after a power cycle without re-homing.
Two voltage rails, one rated point each
On a 380-480 V bus the motor delivers PN = 0.57 kW at nN = 6000 rpm; on the 200-240 V bus PN rises to 0.75 kW at nN = 3000 rpm. The slower speed rating on the lower-voltage rail reflects the higher available torque per amp at reduced speed — pick the operating point that matches the bus the cabinet actually feeds. The current-loop bandwidth is fixed at 8 kHz / 62.5 µs, which is the only tuning the drive side assumes; derating or alternate pulse patterns need to be reconciled against this figure before commissioning. Degree of protection IP65 on the housing means the motor takes washdown and dust exposure in stride on a packaging or conveyor line, but it is not a fully sealed submersible rating — cable entries still need their own gland sealing on the cabinet side.
Compliance posture and stock-keeping unit
Export classification is AL:N / ECCN:N_CNDU, so the part ships without the dual-use licensing paperwork that some higher-power servos carry. Order quantity is 1 piece, with Group Code R220 and Product Group 9021 used internally to slot the line item into a Siemens BOM quotation.
Sourcing posture for the active production line
Lifecycle is recorded as current and the product class flags this as made-to-order — the motor is built against the specific encoder, brake and connector option set, not pulled from a generic shelf. Lead time therefore follows the build queue rather than off-the-shelf stock, and quoting goes through the RFQ path against the configured BOM.
