The ML4404 receives position and velocity\u003c\/div\u003e\n\u003cdiv\u003einformation from a servo controller, such as the\u003c\/div\u003e\n\u003cdiv\u003eML4403, and generates the desired time optimal\u003c\/div\u003e\n\u003cdiv\u003evelocity trajectory. Desired Velocity is then compared\u003c\/div\u003e\n\u003cdiv\u003ewith the actual velocity to create the error signal used by the servo controller.\u003c\/div\u003e\n\u003cdiv\u003eAn anticipate function is included to compensate for phase shift error caused by actuator inductance.\u003c\/div\u003e\n\u003cdiv\u003eAnother feature on the ML4404 is an error measure\u003c\/div\u003e\n\u003cdiv\u003eoutput which averages the velocity error during\u003c\/div\u003e\n\u003cdiv\u003edeceleration, so that the control system can monitor\u003c\/div\u003e\n\u003cdiv\u003eand adjust the necessary transducer gain for minimum\u003c\/div\u003e\n\u003cdiv\u003eaccess time.\u003c\/div\u003e\n\u003cdiv\u003eThe servo system usually requires accurate analog voltages to be set through software control. This is\u003c\/div\u003e\n\u003cdiv\u003eeasily accomplished with a duty cycle to current\u003c\/div\u003e\n\u003cdiv\u003etranslator function on the ML4404. By controlling the\u003c\/div\u003e\n\u003cdiv\u003eduty cycle of a TTL line, a processor can set an analog voltage on the translator output. These translators are\u003c\/div\u003e\n\u003cdiv\u003efully independent blocks which can be used anywhere\u003c\/div\u003e\n\u003cdiv\u003ein the control system.\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Specialty Parts \u0026 Electronic Components, Inc.","offers":[{"title":"Default Title","offer_id":42328114266167,"sku":"327273360464","price":8.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0103\/5124\/7415\/files\/57_aea44bd7-0c82-44a0-9140-6a01b431e1df.jpg?v=1784741187","url":"https:\/\/specialtypartsinc.com\/products\/1-pc-ml4404ycq-micro-linear-interface-circuit-bipolar-plcc-28","provider":"Specialty Parts \u0026 Electronic Components, Inc.","version":"1.0","type":"link"}
