Hi, the actual pinouts or wire numbers are not important, it's the order they are in that is.
To find out this order connect the common white lead to (V+) 7.8V, then connect any other lead to ground (-), call this lead number (4). Lets say you have connected WHITE (common), and RED (4). Leave both these wires connected throughout the rest of the process.
Now connect any other wire to ground (-), let's say the green one. If the motor turns a small increment clockwise, call it number (3), for anticlockwise call it (1), if nothing happens call it (2). Assign the appropriate number to the green wire and disconnect the green wire.
repeat the above paragraph for the remaining coloured wires.
You should now have a "Firing order" for your stepper motor. Much like a car engine, it doesn't matter what number you call the cylnders, if you fire them in the right order the engine will run.
Hope this helps... |
