Motor definition for the SINAMICS S120 axis
The 1FK2104-5AK01-0SB0 is a SIMOTICS S-1FK2 HD servo motor from the 1FK2 family, sized for SINAMICS S120 drives; it carries 0.75 kW at nN = 3000 rpm on a 200-240 V rail and 1.07 kW at nN = 6000 rpm on a 380-480 V rail, with M0 = 2.4 Nm holding torque, in an IP65 housing with a cylindrical shaft D19 x 40 mm (cites:). Encoder is the absolute single-turn AS22DQC at 22-bit resolution, with feedback carried on a DRIVE-CLiQ M17 plug and power on a size M17 connector — the cable set is therefore all DRIVE-CLiQ pre-terminated on the motor side, so commissioning on S120 reduces to plugging the motor into the drive module (cites:). The motor ships under Group Code R220 / Product Group 9021 as a Product Class C line item — built to order, non-returnable for credit, so spare and replacement orders should be sized against confirmed consumption rather than stocked speculatively (cites:,).
Duty envelope and what the ratings actually gate
IP65 on the housing means the motor body tolerates directed water jets and dust ingress, which clears it for food-and-beverable washdown zones when the gland plate and cable entries are seated to the same rating; the encoder and connector faces still require their mating connectors to maintain the wet-end seal (cites:). The encoder is absolute single-turn 22-bit — position is retained only across power cycles within the same turn, so any axis that needs true multi-turn homing memory must look at the AS22DQ multi-turn variant in the same 1FK2 frame rather than substituting this code (cites:).
Compliance and logistics footprint
RoHS compliance has been declared since 01-07-06 and REACH Art. 33 candidate-list information is supplied with the product, which is the documentation set a quality file or PO trace will normally request for this motor (cites:,). Export control classification is AL:N / ECCN:N_CNDU, so the part is not licence-controlled for standard commercial export; packaging is 452.00 x 250.00 x 267.00 mm per single-piece pack, which sets the inbound crate and the shelf footprint for any storeroom holding a critical spare (cites:,).
Sourcing posture for a critical spare
Lifecycle stage is current and the line is active (cites:,).
