Communication velocity depends on the installed processor model and chassis scan time configuration. Firmware flash compatibility is fixed at the hardware revision level; no field-upgradable firmware exists for this module. I\/O density scaling is constrained by the 3-input \/ 1-output channel count per single slot. The module must reside as close to the processor slot as physical chassis layout permits to minimize backplane signal propagation delay.\u003c\/p\u003e\n\u003ch3\u003eOrdering Information\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1 x 1746-HSRV Servo Control Module\u003c\/li\u003e\n\u003cli\u003e1 x Installation instruction sheet\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eMounting \u0026amp; Wiring Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eChassis Placement\u003c\/strong\u003e: Install the module in the slot immediately adjacent to the processor module to reduce backplane latency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounding\u003c\/strong\u003e: Bond the SLC 500 enclosure to system earth ground using a copper conductor of adequate gauge before applying power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSignal Separation\u003c\/strong\u003e: Route analog velocity command wiring separately from 24 VDC discrete I\/O conductors to prevent inductive coupling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTorque\u003c\/strong\u003e: Secure all terminal connections to the torque values specified in the SLC 500 wiring documentation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the 1746-HSRV support hot-swap removal under load?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eNo. Remove power from the SLC 500 chassis before extracting or inserting the module.
