Powered by an embedded 486 DX2 processor running at 66 MHz, this motion module coordinates precise, multi-axis motion loops via an integrated SERCOS fiber optic interface. It bridges high-performance motion control with standard PLC rack architectures for complex industrial automation tasks.\u003c\/p\u003e\n\u003ch3\u003eFunctional Operation and Architecture\u003c\/h3\u003e\n\u003cp\u003eThe module functions as an embedded PC running a dedicated operating system environment, housing three internal printed circuit boards linked via an internal ISA bus. Its core processing unit handles synchronized motion profiles, while the dedicated SERCOS communication board transmits and receives real-time data streams over fiber optic rings to compatible servo drives.\u003c\/p\u003e\n\u003cp\u003eNon-volatile holding registers facilitate seamless data exchange between the motion controller and the main Quantum CPU or other external network nodes. Front-panel LED indicators—including Ready, Run, and Bat Low—alongside a reset key switch, provide immediate feedback on system operational health and network ring status.\u003c\/p\u003e\n\u003ch3\u003eParameter Specifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e141-MMS-425-01 (141MMS42501)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSchneider Electric (Modicon)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eMulti-Axis Servo Controller Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Series\u003c\/td\u003e\n\u003ctd\u003eModicon Quantum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProcessor\u003c\/td\u003e\n\u003ctd\u003e486 DX2 (66 MHz)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Interface\u003c\/td\u003e\n\u003ctd\u003eSERCOS fiber optic (TX\/RX receptacles)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePhysical Slot Requirement\u003c\/td\u003e\n\u003ctd\u003e2 adjacent slots (double-width module)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Power Consumption\u003c\/td\u003e\n\u003ctd\u003e2.5 A at 5 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e2.05 lbs (0.91 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eInstallation and Configuration Requirements\u003c\/h3\u003e\n\u003cp\u003eThe controller requires a double-width slot allocation and can occupy any two available slots within a Quantum rack, operating similarly to standard NOM communication modules. Because it consumes double-width space and draws 2.5 A from the backplane, ensure the rack power supply is adequately dimensioned. Fiber optic cables must be carefully routed to the TX and RX ports on the front faceplate, maintaining proper bend radii to prevent signal degradation along the SERCOS ring.\u003c\/p\u003e\n\u003cp\u003eAn internal backup battery maintains volatile SRAM memory for up to six months when rack power is removed. Ensure the battery is connected prior to system commissioning.\u003c\/p\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What processor speed does the 141-MMS-425-01 module feature? A: It features an embedded 486 DX2 processor operating at a clock speed of 66 MHz.\u003c\/p\u003e\n\u003cp\u003eQ: How many rack slots does this motion controller occupy? A: It requires a double-width housing layout, taking up two adjacent slots in a Quantum backplane.\u003c\/p\u003e\n\u003cp\u003eQ: What is the purpose of the front-panel fiber optic connections? A: The TX and RX receptacles form the SERCOS communication ring used to exchange high-speed control data with compatible industrial servo drives.\u003c\/p\u003e","brand":"SCHNEIDER","offers":[{"title":"Default Title","offer_id":53256578597144,"sku":"141-MMS-425-01","price":179.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/3483\/3688\/files\/141-MMS-425-01.png?v=1794453949","url":"https:\/\/www.innoplcsync.com\/products\/servo-controllers-schneider-electric-141-mms-425-01","provider":"InnoPLC Sync Co., Ltd.","version":"1.0","type":"link"}
