Nearest Absolute
The axis will move in the direction that
gives the shortest path to the Command
Position, as shown below:
The axis will move as if it were a linear
axis. Therefore, the axis will move to
the Command Position in the direction of
increasing position units, as shown
below:
Example 2: Basic Rotary Move
Consider a rotary axis with a single-turn encoder with a Position Unwind value of 360
and a Position Offset of 0. Therefore, the position range extends from 0 up to, but not
including, 360. The current position of the axis is 45. You issue a Move Absolute
command with a Position command parameter of 315. The following illustrations explain
how the axis will behave for each possible Direction parameter:
Positive Negative
The axis will move in the positive
direction to the Command Position, as
shown below:
The axis will move in the negative
direction to the Command Position, as
shown below:
