7358 motion

[vuboy]

I'm using PCI_7358 to control a motor.  What happens if I call the "single axis move" sub vi again on the same axis with the same setting the same setting while the that axis in in operation from the first call (not complete).  Is there any problem (not smooth) in motion as it has to start over from whatever position it's at the time I call the subvi second time or it's smoothly moving to the setting target?

Hi vuboy,

How the motion response behaves will depend on a couple of factors, mainly whether the moves are configured for Absolute Position or Relative Position. There should not be any delay and the motor should continue to complete its move, especially if you are giving it the same target position.

If you are using absolute position moves, the move will simply continue until the target position is reached. If you are using relative position moves, the target positions will effectively be added together. Also, there is a Wait for Move Complete function that can be added if you are concerned about move commands being sent at multiple times.

I hope that helps!
