Motion trajectory calculation runs on the module's onboard logic, not in the processor scan cycle, so position loop closure is unaffected by ladder program execution time. No field-flashable firmware exists; the IMC 110 instruction set is fixed per hardware revision. I\/O density is one axis per single slot, with no daisy-chain expansion on the same module. Place the card in the slot nearest the CPU to keep backplane transaction latency minimal.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x 1746-HS IMC 110 Motion Controller Module\u003c\/li\u003e\n\u003cli\u003e1 x Printed installation and wiring insert\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eChassis Integration Notes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSlot Position\u003c\/strong\u003e: Mount adjacent to the processor module; avoid remote I\/O adapter chassis.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEncoder Wiring\u003c\/strong\u003e: Use shielded twisted pair for A, B, Z lines; terminate shield at the module end only to system ground.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Budget\u003c\/strong\u003e: Sum 300 mA at 5 VDC plus 104 mA at 24 VDC against the 1746 chassis power supply derating curve before commissioning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsolation Boundary\u003c\/strong\u003e: The user-side 5 VDC rail (150 mA) is galvanically isolated from backplane logic; do not tie user encoder supply to backplane 5 VDC.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eIs the 1746-HS hot-swappable on a powered SLC 500 chassis?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. Power down the chassis before insertion or removal.

Phase skew beyond quadrature tolerance reduces the maximum trackable frequency and may double-count; verify encoder cable length against capacitive roll-off.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the module retain position after a backplane power cycle?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. The 1746-HS does not hold absolute position across power loss. The CPU must re-home or preset the axis via M-file commands on restart.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is the isolated user-side 5 VDC 150 mA rail for?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt powers the encoder interface side isolated from backplane logic to suppress ground-loop noise from long cable runs to the motor feedback device.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan two 1746-HS modules synchronize for gearing?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo inter-module camming exists on 1746-HS.
