Position to Element – 2Bh

What the Library Does With This Command

The library will move the picker in front of the specified element at the current media Get position.

Command Usage

This command can be used to pre-position the robotics to an element to enhance performance, or it can be

used as a general-purpose way to relocate the robotics without involving media movement. This might be

useful for diagnostic or demonstration purposes.
