problema driver digital dm556d si interfata db 25 1205


Recommended Posts

Seara buna.Am o problema la legarea celor 2 componente.Am legat motorul conform schemelor de pe net.

Pul+ -p2

Pul- - p3

Dir+ -p4

Dir- -p5

 

p3 si p5 la gnd.

Daca le dau drumu,se blocheaza axu motorului.

Mai sunt 2 pini la driver Ena + respectiv Ena - .

 

Ena+ l*am pus la +5v ... Ena- la gnd.S*a deblocat axul dar nu a pornit ... dandui de lucru din mach 3.

 

Ce am gresit?Imi poate reface cimeva schema de legaturi?Sau e din setarile dr la mach3?

Eu l-as lasa sa il tina blocat, asa sti ca atunci cand ai terminat o operatiune si asteapta dupa altceva nu o sa iti deblocheze motoarele cu riscul sa piarda pasul.

 

Daca vrei sa le deblocheze folosesti pinul ENA pe care il setezi in mach3 parca la Pins->output, nu am mach3 acum in fata. Pinul ENA deblocheaza motorul atunci cand primeste 5v sau gnd, depinde cum e conectat, adica cand se inchide circuitul prin el.
