Hello,
Finally I have all the parts and today I tried to run the motors but unfortunately I failed the step led on the pmdx-126 was blinking when I press the arrows/page up & down keys on keyboard, also the step led on the drivers blinking but no motion or any noise on the motor. Actually I don't know what's wrong !!! No signal at all from the driver outputs.
I have:
Lam technology drivers & motors (DS1078, M1343031) and pmdx-126, antek PS 80VDC 12.5A .
could you please help me ?!
