Is here anyone in Sweden, close Stockholm, that uses step/dir servo drivers? I have problems with my machine with loosing position and need to make a test with another driver.
Anyone who wants to help a guy in need?..

Hi,
I'm not really close to Stockholm but I guess I could send you a drive to try with if a better solution doesn't pop up - if I have one that matches. What type of motor are you driving? PMDC, Brushless AC etc? What voltage and current?
Things to check, in case you haven't already:
Is the polarity of the step- & direction signals correct (ie. active low/high) and is the wiring done accordingly?
Do you have enough current to drive the opto-isolators in the drive (if opto-isolated).
Is the pulsewidth long enough?
Are you losing on all axies or just one?
/Henrik.
Thanks Henrik. Believe me, A LOT is tested.
DC (brush) motors.
if someone has a servo it could be good to try a different driver/servo combination.
