Hellow water2006,
Thank you for using our discussion forums. In regards to continuous mode, are you referring to a constant velocity motion? There are several examples on our website which will give you a good start on setting this up. In particular the "Constant Velocity Move" example which is found at http://zone.ni.com/devzone/cda/epd/p/id/1206
I hope this helps.
