Basic Moves

There are four basic move types:

  • Reference Move—Initializes the axes to a known physical reference such as a home switch or encoder index
  • Straight–Line Move—Moves from point A to point B in a straight line. The move can be based on position or velocity
  • Arc Move—Moves from point A to point B in an arc or helix
  • Contoured Move—A user-defined move; you generate the trajectory, and the points loaded into the motion controller are splined to create a smooth profile

The motion controller uses the specified move constraints, along with the move data, such as end position or radius and travel angle, to create a motion profile in all the moves except the contoured moves. Contoured moves ignore the move constraints and follow the points you have defined.
