ams AS5510 10-bit Linear Incremental Position Sensor me Digital Angle output User Manual

ʻO ka AS5510 kahi mea ʻike ʻo Linear Hall me 10 bit hoʻonā a me I²C interface. Hiki iā ia ke ana i ke kūlana kūʻokoʻa o ka neʻe ʻana i ka ʻaoʻao o kahi magnet 2-pole maʻalahi. Hōʻike ʻia ka hoʻonohonoho maʻamau ma lalo (Figure 1).
Ma muli o ka nui o ka magnet, hiki ke ana ʻia kahi hahau ʻaoʻao o 0.5 ~ 2mm me nā ea ea a puni 1.0mm. No ka mālama ʻana i ka mana, hiki ke hoʻololi ʻia ka AS5510 i ka mana iho ke hoʻohana ʻole ʻia.

Ke kau nei i ka papa Adapter AS5510

Hiki ke hoʻopaʻa ʻia ka AS5510-AB i kahi ʻōnaehana mechanical e loaʻa nei e kona mau puka kau ʻehā. Hiki ke hoʻohana ʻia kahi magnet 2-poles i kau ʻia ma luna a ma lalo paha o ka IC.

AS5510 ka hoʻopili ʻana i ka papa adapter a me ka nui

ʻO ka huakaʻi ākea kiʻekiʻe amppili ka litude i ke ʻano magnet a me ka nui a me ka ikaika magnetic (mea magnet a me airgap).
I mea e ana i ka neʻe ʻana o ka mechanical me ka pane laina, e like ke ʻano o ke kahua magnetic ma kahi airgap paʻa ma ke Kiʻi 5:.
ʻO ka laulā laina laina o ka mākia ma waena o nā pole ʻĀkau a me ka Hema e hoʻoholo ai i ka nui o ka huakaʻi hele o ka magnet. ʻO ka liʻiliʻi (-Bmax) a me ka kiʻekiʻe (+Bmax) koʻikoʻi o ka laina laina pono e haʻahaʻa a i ʻole like me kekahi o nā ʻehā ʻehā i loaʻa ma ka AS5510 (kakau inoa 0Bh): Sensitivity = ± 50mT, ± 25mT, ±18.5mT , ± 12.5mT ʻO ka papa inoa puka 10-bit D[9..0] OUTPUT = Field(mT) * (511/Sensitivity) + 511.

ʻO kēia ka hihia kūpono: ʻo ka laina laina o ka magnet he ± 25mT, kūpono i ka ± 25mT sensitivity hoʻonohonoho o ka AS5510. ʻOi aku ka maikaʻi o ka hoʻonā ʻana o ka neʻe ʻana vs.
Max. Ka mamao hele TDmax = ±1mm ( Xmax = 1mm)
ʻIke = ±25mT (Kakau 0Bh ← 01h)
Bmax = 25mT
→ X = -1mm (= -Xmax) Kahua(mT) = -25mT OUTPUT = 0
→X = 0mm Kahua(mT) = 0mT OUTPUT = 511
→ X = +1mm (= +Xmax)
Kahua(mT) = +25mT OUTPUT = 1023
ʻO ka laulima ikaika o OUTPUT ma luna o ±1mm: DELTA = 1023 – 0 = 1023 LSB
Hoʻoholo = TDmax / DELTA = 2mm / 1024 = 1.95µm/LSB
Exampka 2:
Ke hoʻohana nei i nā hoʻonohonoho like ma ka AS5510, ʻo ka laina laina o ka magnet ma luna o ka neʻe like ʻana o ± 1mm i kēia manawa ± 20mT ma mua o ± 25mT ma muli o kahi airgap kiʻekiʻe a i ʻole kahi magnet nāwaliwali. I kēlā hihia, ʻoi aku ka haʻahaʻa o ka hoʻonā o ka neʻe ʻana vs. Max. Ka lōʻihi o ka huakaʻi TDmax = ±1mm (Xmax = 1mm): ʻaʻole i hoʻololi ʻia ʻo Sensitivity = ±25mT (Kakau inoa 0Bh ← 01h): ʻaʻole i hoʻololi ʻia
Bmax = 20mT
→ X = -1mm (= -Xmax)
Kahua(mT) = -20mT OUTPUT = 102
→ X = 0mm Kahua(mT) = 0mT OUTPUT = 511
→ X = +1mm (= +Xmax)
Kahua(mT) = +20mT OUTPUT = 920;
ʻO ka laulima ikaika o OUTPUT ma luna o ±1mm: DELTA = 920 – 102 = 818 LSB
Hoʻoholo = TDmax / DELTA = 2mm / 818 = 2.44µm/LSB
I mea e mālama ai i ka hoʻonā maikaʻi loa o ka ʻōnaehana, ua ʻōlelo ʻia e hoʻololi i ka sensitivity e like me ka Bmax o ka magnet, me Bmax < Sensitivity e pale i ka saturation o ka waiwai hoʻopuka.
Inā hoʻohana ʻia kahi mea hoʻopaʻa magnet, pono ia e hana ʻia me kahi mea non-ferromagnetic i mea e mālama ai i ka ikaika o ke kahua magnetic a me ka laina kiʻekiʻe. ʻO nā mea e like me ke keleawe, ke keleawe, ke alumini, ke kila kila nā koho maikaʻi loa e hana i kēia ʻāpana.

Hoʻohui i ka AS5510-AB

ʻElua uea (I²C) wale nō ke koi ʻia no ke kamaʻilio ʻana me ka MCU hoʻokipa. Pono nā mea pale huki ma ka laina SCL a me SDA. Aia ka waiwai i ka lōʻihi o nā uea, a me ka nui o nā kauā ma ka laina I²C like.
Hoʻopili ʻia ka mana hāʻawi ma waena o 2.7V ~ 3.6V i ka papa adapter a me nā mea huki huki.
Hiki ke hoʻohui ʻia ka lua AS5510 adapterboard (koho) ma ka laina like. I kēlā hihia, pono e hoʻololi i ka helu I²C ma ka pani ʻana iā JP1 me kahi uea.

lako polokalamu example

Ma hope o ka hoʻoikaika ʻana i ka ʻōnaehana, pono e hana ʻia kahi lohi o >1.5ms ma mua o ka I²C mua
Heluhelu/Kākau i ke kauoha me ka AS5510.
ʻO ka hoʻomaka ʻana ma hope o ka hoʻāla ʻana he koho. Aia i loko o:
- Ka hoʻonohonoho ʻana i ka naʻau (kakau inoa 0Bh)

Mākēneki polarity (Kakau 02h bit 1)

ʻAno lohi a wikiwiki paha (Kakau inoa 02h bit 3)
Ke ʻano hoʻohaʻahaʻa mana (Kakau inoa 02h bit 0)

ʻO ka heluhelu ʻana i ka waiwai mākēneki pololei i mua. Heluhelu ke kumu kumu ma lalo nei i ka 10 -bit magnetic field value, a hoʻololi i ka ikaika mākia ma mT (millitesla).
Example: Hoʻonohonoho ʻia ka naʻau i ka laulā +-50mT (97.66mT/LSB); Polarity = 0; hoʻonohonoho paʻamau:

D9..0 waiwai = 0 'o ia hoʻi -50mT ma ka hale nanea.

D9..0 waiwai = 511 'o ia ho'i he 0mT ma ka hale 'ike ('a'ohe mākēneki, a 'a'ohe magnet).
D9..0 waiwai = 1023 'o ia hoʻi + 50mT ma ka hale ʻike.
