Title: Detecting Fwd and reverse of Axis
Post by: codegrush on December 12, 2009, 12:32:26 AM

Hi, I'm trying to detect when my A axis if moving forward or reverse. when moving forward it will actuate a solenoid valve and in reverse it will actuate a different valve and only when it is moving.

I'm new to brains but can someone help me with this? I don't see a dro for direction in the variable list.

Thanks,
  David P
