Rotatie Pan si Tilt la Movihead

Recommended Posts

Am o problema cu un movihead tampit facut de FAL de 250! Sa va explic:Rotatia de PAN si TILT la moviheaduri au un opto senzor ce detecteaza miscare si de obicei un microswitch pentru cap de cursa. Ei problema la Fal este ca lipseste acest switch pentru cap de cursa...Am asa ceva la reparat care nu reuseste sa faca pozitia zero ...adica el merge pana la capatul mecanic si nu se opreste...decat dupa vrun minut de incercare..ceea ce nu e bine deloc pentru curele si motor! Alta problema este ca si Pan si Tilt si Focalizare au aceleasi simptome! Rationamentul meu este ca face capul de cursa prind detectie de curent pe motorul pas cu pas! A mai intalnit cineva asa ceva ?!

Am rezolvato....facea pozitia zero pe timp...asa ca el 30 de sec. incerca sa duca toate motorasele la zero chiar daca sunt la zero! Si gata cred ca e inchis topicul!
