Status and what this part actually is
The ILS1F573S1333: The device is a Lexium ILS stepper motor rated for a 24-36 VDC bus with a CAN interface — that combination places it in the compact, low-voltage DC segment of the Lexium family typically paired with a matched stepper drive in machine-builder cabinets where CANopen-style networking feeds motion commands alongside other nodes on the same fieldbus trunk.
Sourcing posture for an obsolete stepper
With production closed, the realistic supply path runs through independent distribution rather than direct franchised inventory: quote the exact order code against an RFQ, and lot-specific availability, warranty traceability, and lead time come back with the quote rather than off a live stock indicator. The spec sheet places this entry under Servo Drives even though the part description reads as a stepper motor — that mix is typical for integrated Lexium motion packages where the drive and motor share one order-code family.
Field-fitting notes for the ILS1F57 frame
The 24-36 VDC bus means cabinet-side the drive expects a regulated low-voltage DC rail rather than a rectified mains bus, which simplifies fusing and lets the unit sit on the same 24 VDC backplane that feeds I/O if the integration plan already runs SELV rails through the panel. CAN connectivity implies a node address and a PDO/SDO map on commissioning — the message profile has to be loaded from the Lexium configuration tool before the motor will respond to the first motion command, so a spare configuration file belongs in the documentation pack issued at delivery.
