Mitsubishi Elevator Brake Circuit (BK) Kuwongolera Mavuto

Circuit ya Brake (BK)

1 Mwachidule

Mabwalo a mabuleki amagawidwa m'magulu awiri:olamuliridwa pakali panondiresistive voltage divider-controlled. Zonse zikuphatikizapokuyendetsa maulendondikulumikizana ndi mabwalo oyankha.

1.1 Mabuleki Oyendetsedwa Pakalipano

• Kapangidwe:

  • Kuyendetsa Circuit: Mothandizidwa ndi #79 kapena S420, yoyendetsedwa ndi #LB contactor.

  • Feedback Circuit: Zizindikiro zolumikizirana ndi brake (zotseguka / zotsekedwa) zotumizidwa mwachindunji ku matabwa a W1/R1.

• Ntchito:

  1. #LB cholumikizira chimatseka → Control unit (W1/E1) iyambitsa.

  2. Control unit imatulutsa mphamvu ya brake → Brake imatsegulidwa.

  3. Olumikizana nawo amatumiza mawonekedwe a zida.

Schematic:

1.2 Resistive Voltage Divider-Controlled Brake Circuit

• Kapangidwe:

  • Kuyendetsa Circuit: Mulinso ma resistors ogawa ma voltage ndi olumikizirana nawo.

  • Feedback Circuit: Imayang'anira malo achitetezo kudzera pa ma NC/NO.

• Ntchito:

  1. Brake Yatsekedwa: NC imalumikizana ndi zopinga zazifupi → voliyumu yonse yayikidwa.

  2. Brake Open: Kusuntha kwa Armature → Kulumikizana kwa NC kutsegulidwa → Zotsutsa zimachepetsa voteji mpaka mulingo wokonza.

  3. Ndemanga Yowonjezera: Zowonjezera PALIBE olumikizana amatsimikizira kutsekedwa kwa brake.

Zolemba Zofunikira:

• ZaZPML-A makina okokera, kusintha kwa mabuleki kumakhudza mwachindunji kuyenda kwa zida (zabwino: ~ 2mm).

2 Njira Zothetsera Mavuto Onse

2.1 Kulephera Kuchita Mabuleki

Zizindikiro:

• Brake imalephera kutsegula/kutseka (mbali imodzi kapena zonse ziwiri).

• Zindikirani: Kulephera kwa mabuleki kwathunthu kungayambitse kutsetsereka kwagalimoto (zowopsa zachitetezo).

Njira Zowunika:

1. Onani Voltage:

   • Tsimikizirani mphamvu yamagetsi yonse pakutsegula ndi kukonza magetsi pambuyo pake.

   • Gwiritsani ntchito ma multimeter kuyeza mphamvu ya koyilo (mwachitsanzo, 110V ya #79).

2. Yang'anani Ma Contacts:

   • Sinthani njira yolumikizirana (pakati paziwongolero zapano; pafupi ndi malekezero aulendo kuti muzitha kuwongolera).

3. Macheke a Makina:

   • Lubricate mgwirizano; onetsetsani kuti palibe zopinga panjira ya zida.

   • Sinthanibrake gap(0.2-0.5mm) nditorque springkukangana.

2.2 Ndemanga Zolakwika za Signal

Zizindikiro:

• Brake imagwira ntchito bwino, koma bolodi la P1 likuwonetsa zizindikiro zokhudzana ndi brake (mwachitsanzo, "E30").

Njira Zowunika:

1. M'malo Ndemanga Contacts: Yesani ndi zigawo zodziwika bwino.

2. Sinthani Malo Olumikizirana:

   • Kuti muzitha kuwongolera: Lumikizani zolumikizana pafupi ndi mapeto a ulendo wa zida.

3. Onani Wiring wa Signal:

   • Tsimikizirani kupitiliza kuchokera pamalumikizidwe kupita pama board a W1/R1.

2.3 Zolakwika Zophatikizana

Zizindikiro:

• Kulephera kwa Brake + ma code olakwika.

Yankho:

• Pangani kusintha kwa brake yonse pogwiritsa ntchito zida ngatiZPML-A Brake Calibration Chipangizo.

3 Zolakwika Zofala & Mayankho

3.1 Brake Imalephera Kutsegula

3.2 Kusakwanira kwa Braking Torque

4. Zithunzi

Chithunzi : Brake Circuit Schematics

• Ulamuliro Wamakono: Topology yosavuta yokhala ndi njira zodziyimira pawokha / zoyankha.

• Resissive Control: Magetsi ogawanitsa ma voltages ndikuwonjezera mayankho amawu.

Zolemba Zolemba:
Bukuli likugwirizana ndi miyezo ya Mitsubishi elevator. Nthawi zonse tsatirani ndondomeko zachitetezo ndikuyang'ana zolemba zaukadaulo kuti mumve zambiri zachitsanzo.
