Two rail options, same frame: the motor runs the 1 kW point on a 380–480 V supply and drops to 0.5 kW at 1500 rpm on a 200–240 V supply, so a retrofit onto an existing 230 V drive bus is a sizing question, not a re-engineering one. The shaft is D19x40 mm with a feather key, the body is IP65 sealed, feedback is an absolute encoder AM22DQC (22-bit single-turn + 12-bit multiturn), and both the DRIVE-CLiQ signal plug and the power connector are M17 size — meeting it where it is in an existing SINAMICS S120 cabinet. ## Backplane, feedback, and connector stack DRIVE-CLiQ on the M17 plug carries the encoder and motor data straight into a SINAMICS S120 drive — no extra encoder cable to spec — and the same M17 family handles the power side, so the cabinet-side wiring stays in one connector family. The 22-bit + 12-bit multiturn absolute encoder means the drive retains absolute position across power cycles, which matters on vertical axes or any load that can drift on de-energise; the holding brake takes the static load after the stop. ## Sizing notes for a retrofit window At 1 kW on the 400 V class rail the motor lands in the mid-frame 1FK2 HD slot; the IP65 housing and D19x40 keyed shaft are the mounting constants when comparing to whatever is being replaced on a 1990s machine. For an existing line, the practical check is whether the 1 kW / 3000 rpm point covers the original duty cycle, and whether the existing cabinet can land DRIVE-CLiQ — that is the part of the upgrade that decides whether the swap is a motor-only change or a drive-side rework. ## Lifecycle and compliance posture Product status is active on the current lifecycle record, and the product class is C — built to order, non-returnable, non-reusable — so the motor is configured and manufactured per order rather than pulled from shelf stock.
