For a typical reversing cyclic positioning application, at any point in the cycle, your Desired Position is at most +50.00% (moving forward) or -50.00% (moving backwards) of the Cycle Length away from your Current Position. Therefore, when using the positioning function blocks, the Output yields a position error between +/-50.00%.

This function block is intended for non-reversing cyclic positioning applications. Positive values (0.00% to +50.00%) are passed through unchanged. Negative values (-49.99% to -0.01%) are translated to positive values (50.01% to 99.99%). The negative values are translated to positive values the with the same physical position so the entire cycle may be smoothly traversed with only positive control values.

The bipolar value to be converted to a unipolar value.

The unipolar value which may be used as a non-reversing control output.
