Thank you GredW for the reply and sorry for responding it late. I want to send the external pulse to the driver using the LabView, maybe in this case we can use pin 34 35( servo ready). I want to control the position and speed of the traverse by using this external pulse. I am new in servo motor and labview, so i am having difficulty while working on this one. Do you have any LabView code which can communicate with the servo driver and manipulate position, velocity or acceleration?
