Txhawm rau ua tiav cov qib theem siab, lub cev muaj zog feem ntau ntau dua li yuav raug tso cai yam tsis muaj kev txwv tam sim no. Piv txwv li, tus tsav lub cev muaj zog tuaj yeem muaj qhov ntsuas siab tshaj tam sim no ntawm 1A nrog 5Ω kauj tsis kam, uas yuav qhia txog lub zog loj tshaj plaws ntawm 5 V. txwv rau qis dua 1A txhawm rau tiv thaiv kev puas tsuaj rau lub cav.

A4988 txhawb qhov kev txwv tam sim no, thiab lub tshuab txiav potentiometer ntawm lub rooj tsavxwm tuaj yeem siv los teeb tsa qhov txwv tam sim no. Ib txoj hauv kev los teeb tsa qhov txwv tam sim no yog tso tus neeg tsav tsheb mus rau hauv hom-kauj ruam thiab ntsuas qhov tam sim no khiav los ntawm ib lub cav uas tsis siv lub sijhawm ntsuas STEP cov tswv yim. Qhov ntsuas tam sim no yuav yog 0.7 npaug ntawm qhov txwv tam sim no (txij li ob lub coils ib txwm nyob thiab txwv rau 70% ntawm qhov txwv tam sim no teeb tsa nyob rau hauv hom puv kauj ruam). Thov nco ntsoov tias kev hloov lub logic voltage, Vdd, mus rau tus nqi sib txawv yuav hloov qhov kev txwv tam sim no txij li qhov hluav taws xob ntawm tus lej "ref" yog qhov ua haujlwm ntawm Vdd. Lwm txoj hauv kev los teeb tsa qhov txwv tam sim no yog ntsuas qhov hluav taws xob ncaj qha rau sab saum toj ntawm lub hwj chim thiab los laij qhov txwv tam sim no (qhov kev nkag siab tam sim no yog 0.1Ω). Qhov txwv tam sim no cuam tshuam nrog qhov ntsuas hluav taws xob raws li hauv qab no: Tam sim no Txwv = VREF × 1.25 Yog li, piv txwv li, yog tias qhov ntsuas hluav taws xob yog 0.6 V, qhov txwv tam sim no yog 0.75A. Raws li tau hais los saud, nyob rau theem puv hom, tam sim no los ntawm cov coils tau txwv rau 70% ntawm qhov txwv tam sim no, yog li kom tau txais cov kauj ruam puv kauj tam sim no ntawm 1A, qhov txwv tam sim no yuav tsum yog 1A/0.7 = 1.4A, uas sib xws rau VREF ntawm 1.4A/1.25 = 1.12 V. Saib A4988 daim ntawv qhia kom paub ntau ntxiv. Nco tseg: Cov kauj tam sim no tuaj yeem sib txawv heev los ntawm cov khoom siv hluav taws xob tam sim no, yog li koj yuav tsum tsis txhob siv qhov ntsuas tam sim no ntawm lub hwj chim los teeb tsa qhov txwv tam sim no. Qhov chaw tsim nyog los tso koj lub ntsuas cua tam sim no yog nyob rau hauv nrog ib qho ntawm koj cov stepper lub cev muaj zog coils.
